UNPACKING Carefully remove the CD30 dehumidifier unit from its transit box and visually check for signs of transit damage. If there is evidence of damage DO NOT attempt to operate the unit, call your supplier for advice. Do not discard the packing; it will be useful when transporting the dehumidifier unit in the future.
INTRODUCTION The Ebac CD30 industrial dehumidifier removes moisture from the air through the refrigeration process. The Ebac CD30 is basically comprised of: A) B) C) D) E) F) G) H)
A compressor A refrigerant evaporator coil A refrigerant condenser coil One circulation fan A drain tray for collecting and disposing of condensed moisture A solid state timer for hot gas defrost cycle An adjustable membrane-type humidistat A cabinet to house the above components
The fan draws the moist air through the cold evaporator coil which cools the air below its dew point. Moisture forms on the evaporator coil and is collected in the condensate tray which is equipped with a permanent drain. The cooled air then passes through the hot condenser coil where it is reheated using the same energy removed during the cooling phase plus the additional heat generated by the compressor. The air is, therefore discharged from the dehumidifier at a slightly higher temperature with a lower absolute humidity, than that which entered. Continuous circulation of air through the dehumidifier gradually reduces the relative humidity within the area. The CD30 dehumidifier is a rugged reliable drying unit designed to operate effectively over a broad range of temperature and humidity conditions. A powerful and reliable active hot gas defrost system, controlled by an electronic timer, guarantees positive de-icing, thereby optimizing operation at low temperatures. The unit incorporates a welded steel chassis and is finished in an epoxy coating for resilience to damage caused by rough handling. The CD30 dehumidifier is fitted with an adjustable humidistat to enable you to select the level of dryness.

OPERATION The operation of the dehumidifier is to remove moisture from the air by having it condense on the cold tubes of the evaporator coil. The air then passes over the hot condenser coil and returns to the conditioned space slightly warmer and dryer than when it entered the dehumidifier unit. TEST FOR CORRECT OPERATION The following procedures should be followed to test the CD30 for correct operation. 1. After unpacking, examine all external features to confirm damage free shipment. Report all defects and damage at once. 2. Check dehumidification process: a) Place unit on a level surface. b) Start up unit by rotating the adjustable humidistat knob counter clockwise to the minimum setting. Plug in the unit to a grounded receptacle with a 15 amp power source. Rotate the humidistat knob clockwise to the maximum setting. c) Check the compressor is running. d) Leave the machine running for 15 minutes. e) Observe the evaporator coils, to confirm frost formation. i. If the air temperature is below 70ºF, an even coating of frost should cover the entire evaporator coils, except for the last one or two coils. ii. If the temperature is above 70ºF, frost and/or droplets of condensed water should cover the entire evaporator coil. If after carrying out all the above checks, the unit does not appear to function correctly refer to the section, “Trouble Shooting”, or contact your supplier. WARNING: •
Due to the high pressures within the refrigeration circuit, under no circumstances must direct heat be applied to the evaporator coil in an attempt to remove the build up of ice. • No attempt should be made to cut open any part of the refrigeration circuit due to high pressures and gas involved. If the unit is switched off at the mains power supply for any reason, the unit must be allowed to stand at rest for at least three minutes before restarting. Failure to do so may cause the unit to blow the fuses owing to the compressor due to there being a refrigerant imbalance.
SPECIAL FEATURES (Where Fitted) Control Humidistat This humidistat operates in the same way as the normal humidistat to control the on/off function of the dehumidifier units, but is factory pre-set at 55% RH to maintain the relative humidity air at the set point.
Alarm Humidistat This humidistat, which has been factory pre-set at 70% RH, allows for connection to an external warning system. This warning indicating system will be monitored by the customer and will warn and indicate when the relative humidity of the air within the room has risen above a warning level due to a fault, either with the dehumidifier or due to some other circumstances and will require a service engineer. NOTE RATING OF ALARM HUMIDISTAT IS 3.5A @ 240V Alarm Wiring:
Plug L – Normally open contacts Plug N – Close on humidity rise Plug E – Earth
ROUTINE MAINTENANCE WARNING: ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN DISCONNECTED BEFORE CARRYING OUT ROUTINE MAINTENACE ON ITEMS 1, 2, 3, AND 4. To ensure continued full efficiency of the dehumidifier, maintenance procedures should be performed as follows:
1.
Clean the surface of the evaporator and condenser coils by blowing the dirt out from behind the fins with compressed air. Hold the nozzle of the air hose away from the coil (approx 6”) to avoid damaging the fins. Alternatively, vacuum clean the coils. WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS
2.
Check that the fan is firmly secured to the motor shaft and that the fan rotates freely. The fan motor is sealed for life and therefore does not need oiling.
3.
To check the refrigerant charge, run the unit for 15 minutes and briefly remove the cover. The evaporator coil should be evenly frost coated across its surface. At temperatures above 25°C, the coil may be covered with droplets of water rather than frost. Partial frosting accompanied by frosting of the thin capillary tubes, indicates loss of refrigerant gas or low charge.
4.
Check all wiring connections.
5. To check the operation of the defrost system, switch the machine on and leave it running for approximately 45 minutes. The machine will then enter “Hot Gas” defrost mode for approximately 4 minutes before returning to normal operation. If the unit will not defrost, the printed circuit timer board may be defective or the by-pass valve may be inoperable.
IF ANY OF THE PRECEDING PROBLEMS OCCUR, CONTACT THE EBAC SERVICE CENTER PRIOR TO CONTINUED OPERATION OF THE UNIT TO PREVENT PERMANENT DAMAGE.
REPAIRS 1.
Should an electrical component fail, consult the Factory Service Center to obtain the proper replacement part.
2.
If refrigerant gas is lost from the machine, it will be necessary to use a refrigeration technician to correct the fault. Contact the Factory Service Center prior to initiating this action. Any competent refrigeration technician will be able to service the equipment. The following procedure must be used: a. The source of the leak must be determined and corrected. b. The machine recharging.
should
be
thoroughly
evacuated
before
c. The unit must be recharged with refrigerant measured accurately by weight. d. For evacuation and recharging of the machine, use the crimped and brazed charging stub attached to the side of the refrigerant compressor. The charging stub should be crimped and rebrazed after servicing. NEVER allow permanent service valves to be fitted to any part of the circuit. Service valves may leak causing further loss of refrigerant gas. 3.
The refrigerant compressor fitted to the dehumidifier is a durable unit that should give many years of service. Compressor failure can result from the machine losing its refrigerant gas. The compressor can be replaced by a competent refrigeration technician. Failure of the compressor can be confirmed by the following procedure: a. Establish that power is present at the compressor terminals using a voltmeter. b. With the power disconnected, check the continuity of the internal winding by using meter across the compressor terminals. An open circuit indicates that the compressor should be replaced. c. Check that the compressor is not grounded by establishing that a circuit does not exist between the compressor terminals and the shell of the compressor.

INTRODUCTION Dehumidifiers remove moisture from the air that is circulating through the unit. The resulting reduction of relative humidity helps prevent rust, rot, mould, mildew and condensation within the room, or other enclosed spaces where the dehumidifier is used. A dehumidifier consists of a motor-compressor unit, a refrigerant condenser, an air circulating fan, a refrigerated surface, a means of collecting and disposing the condensed moisture and a cabinet to house these components. The fan draws air through the refrigerated surface and cools it below its dew point, removing moisture which is collected and led away. The cool air then passes the hot condenser, where it is reheated. With the addition of other radiated heat the air is discharged into the room at a higher temperature but lower relative humidity than when the air entered the unit. Continuous circulation of the room air through the dehumidifier unit gradually reduces the relative humidity in the room. The CD30 has been designed for the exacting conditions which can prevail in offices, shops, houses, restaurants, public houses etc. It combines lightness and compactness with high reliability and strength. The gas, which is used inside the hermetically sealed refrigeration circuit is R134a and contains no CFC’s and has therefore a zero ozone depletion factor.

INSTALLATION POSITIONING: Position the dehumidifier unit in the center of the room to be conditioned if at all possible. However if a damp patch is particularly apparent the outlet grille should be pointed towards it. NOTE: Both inlet grille and outlet grille of the dehumidifier unit must have clear space around them and not be obstructed in anyway. WIRING: Connect the power mains cable to a 5 or 13 Amp power supply. As follows:230V supply Brown
Live
Blue
Neutral
Green/Yellow
Earth (ground)
DRAINAGE: Connect a 12.5mm inside diameter hose to the condensate outlet pipe (positioned centrally, beneath the air inlet grille). Secure the hose using a worm drive clip. The hose should at no point be raised higher than the outlet pipe. Failure to observe this requirement will result in flooding of the dehumidifier.
OPERATION The operation of the dehumidifier is to remove moisture from the air by having it condense on the cold tubes of the evaporator coil. The air then passes over the hot condenser coil and returns to the conditioned space slightly warmer and dryer than when it entered the dehumidifier unit. AIR MOVING SYSTEM: Air is drawn in through the inlet grille at the rear of the dehumidifier (below the handle) and over the two heat exchanges (evaporator/condenser coils) under the influence of the axial fan, which is driven by the motor. The operation of the fan is to run continuously whenever the power is supplied to the dehumidifier. The fan motor used in the dehumidifier unit is induction protected i.e. the motor is able to take stalled current without burning out the motor windings. DEFROST OPERATION: Should the ambient temperature fall below 15°C the ice will form on the evaporator coil as the air is passed over it, and in turn the efficiency of the unit will drop. To prevent the build up of ice on the evaporator coil a timer is incorporated to energize the hot-gas defrost valve every 55mins for a period of 4mins. Operating the hot-gas valve causes the evaporator coil to defrost and the water to drain down to the condensate pan and into the drainage tube. HIGH TEMPERATURE CUTTOUT: The CD30 dehumidifier has been designed to work in ambient temperatures between -5°C and +35°C. Should the temperature in the room become excessive a thermostat within the compressor casing will open and dehumidifying will stop, until the thermostat resets itself. HUMIDISTAT CONTROL: The CD30 is fitted with a control humidistat, which measures the relative humidity of the air within the room to be conditioned. The humidistat incorporates a pointer and scale, which can be adjusted, and set to a relative humidity level that is acceptable to maintain the required conditions within the room. The humidistat controls the on/off function of the dehumidifier, when the relative humidity of the air in the room falls below the set point of the humidistat the dehumidifier will switch off, but when the relative humidity of the air starts to rise again and passes the set point the unit will switch on. The humidistat is used for the on/off function as it is a cost effective method which ensures power is only used when needed.
WARNING: • • •
Due to the high pressures within the refrigeration circuit, under no circumstances must direct heat be applied to the evaporator coil in an attempt to remove the build up of ice. No attempt should be made to cut open any part of the refrigeration circuit due to high pressures and gas involved. If the unit is switched off at the mains power supply for any reason, the unit must be allowed to stand at rest for at least three minutes before restarting. Failure to do so may cause the unit to blow the fuses owing to the compressor due to there being a refrigerant imbalance.
SPECIAL FEATURES (Where Fitted)
Temperature Controlled Defrost The CD30 Dehumidifier unit can be fitted with temperature sensitive devices which will operate in conjunction with the defrost control. In normal operation the defrost control will come into operation every 55minutes, this is to ensure that there will be no build up of ice at lower temperatures, but where year round conditions need to be maintained the dehumidifier will have to operate across a wider range of temperatures. To ensure that the dehumidifier operates most efficiently this temperature sensitive device will restrict the operation to the times when the evaporator coil is at –2ºC. Heated Condensate Drainage Tube The CD30 dehumidifier unit can be fitted with a heater tape, which will run the length of the condensate drainage tube. The effect of this heated condensate drainage tube will ensure that when the drainage point for the unit is not in the same room, but is run outside the room and could fall below freezing point, the tube will be warm enough to still allow the condensate to flow. Control and Warning Indicator Humidistat The CD30 dehumidifier can be fitted with a control panel, fixed to the outside of the cabinet. The panel will incorporate two humidistats which both measure the relative humidity of the air. The first humidistat incorporates a pointer and scale (as previously mentioned) and is identified as “control”. The second humidistat is situated adjacent to the control humidistat and is identified as “alarm”. This is fitted with a coloured knob to the shaft of the humidistat for easy identification. Ebac will set this humidistat to the individual customer’s requirements upon request. Control Humidistat This humidistat operates in the same way as the normal humidistat to control the on/off function of the dehumidifier units, but is factory pre-set to maintain the relative humidity air at the set point.
Alarm Humidistat This humidistat, which has been factory pre-set, allows for connection to a warning system. This warning indicating system will be monitored by the customer and will warn and indicate when the relative humidity of the air within the room has risen above a warning level due to a fault, either with the dehumidifier or due to some other circumstances and will require a service engineer. NOTE RATING OF ALARM HUMIDISTAT IS 3.5A @ 240V Alarm Wiring:
Plug L – Normally open contacts Plug N – Close on humidity rise Plug E – Earth
ROUTINE MAINTENANCE WARNING: ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN DISCONNECTED BEFORE CARRYING OUT ROUTINE MAINTENACE ON ITEMS 1, 2, 3 AND 4.
To ensure continued full efficiency of the dehumidifier, maintenance procedures should be performed as follows: Removal of the cover is achieved by means of four screws at the sides of the unit at base level. With the cover removed all maintenance can be carried out. 1.
Clean the surface of the evaporator and condenser coils by blowing the dirt out from behind the fins with compressed air. Hold the nozzle of the air hose away from the coil (approx 6”) to avoid damaging the fins. Alternatively, vacuum clean the coils. WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS
2.
Check that the fan is firmly secured to the motor shaft and that the fan rotates freely. The motor is sealed for life and does not require any lubrication
3.
To check the refrigerant charge, run the unit for 15 minutes and briefly remove the cover. The evaporator coil should be evenly frost coated across its surface. At temperatures above 25°C, the coil may be covered with droplets of water rather than frost.

INTRODUCTION
Designed for a wide range of applications, the CD85 dehumidifier is a rugged, industrial unit which utilizes an energy-efficient compressor and a compact portable design to provide easy efficient drying.
The CD85 has a number of special features:
• • • • • • • •
Compact Size High efficiency rotary compressor Ebac’s “Hot Gas” defrost system Exterior epoxy powder-coated finish Provision for permanent drainage All galvanized interior Extra long power cord Humidistat
The fan draws the moist air through the cold evaporator coil, which cools the air below its dew point. Moisture forms on the evaporator coil and is collected in the condensate tray, which is equipped with a permanent drain. The cooled air then passes through the hot condenser coil where it is reheated using the same energy removed during the cooling phase, plus the additional heat generated by the compressor. The air is, therefore, discharged from the dehumidifier at a slightly higher temperature with a lower absolute humidity than that which entered. Continuous circulation of air through the dehumidifier gradually reduces the relative humidity within the area.
The CD85 dehumidifier is a rugged, reliable drying unit designed to operate effectively over a broad range of temperature and humidity conditions. An active hot gas defrost system, controlled by an electronic timer, guarantees positive de-icing, thereby optimizing operation at low temperatures.
The unit incorporates a welded and galvanized steel chassis and is finished in an epoxy coating for resilience to damage caused by rough handling.

CD85 INDUSTRIAL DEHUMIDIFIER OWNER’S MANUAL
INTRODUCTION
Designed for a wide range of applications, the CD85 dehumidifier is a rugged, industrial unit which utilizes an energy-efficient compressor and a compact portable design to provide easy efficient drying.
The CD85 has a number of special features:
• • • • • • • •
Compact Size High efficiency rotary compressor Ebac’s “Hot Gas” defrost system Exterior epoxy powder-coated finish Provision for permanent drainage All galvanized interior Extra long power cord Humidistat
The fan draws the moist air through the cold evaporator coil, which cools the air below its dew point. Moisture forms on the evaporator coil and is collected in the condensate tray, which is equipped with a permanent drain. The cooled air then passes through the hot condenser coil where it is reheated using the same energy removed during the cooling phase, plus the additional heat generated by the compressor. The air is, therefore, discharged from the dehumidifier at a slightly higher temperature with a lower absolute humidity than that which entered. Continuous circulation of air through the dehumidifier gradually reduces the relative humidity within the area.
The CD85 dehumidifier is a rugged, reliable drying unit designed to operate effectively over a broad range of temperature and humidity conditions. An active hot gas defrost system, controlled by an electronic timer, guarantees positive de-icing, thereby optimizing operation at low temperatures.
The unit incorporates a welded and galvanized steel chassis and is finished in an epoxy coating for resilience to damage caused by rough handling.
COVERS The CD85 covers can be swapped to allow the airflow direction to be changed to better suit the application the unit is to be used for. To change the covers, first remove the 4 off retaining screws and washers from each cover, swap cover positions and replace 4 off retaining screws and washers. If changing the evaporator covers then the filter retaining mesh should always be placed behind the Evaporator Grille Cover. This is held in place with 4off M3 hex head bolts.

INTRODUCTION Dehumidifiers remove moisture from the air that is circulating through the unit. The resulting reduction of relative humidity helps prevent rust, rot, mould, mildew and condensation within the room, or other enclosed spaces where the dehumidifier is used. A dehumidifier consists of a motor-compressor unit, a refrigerant condenser, an air circulating fan, a refrigerated surface, a means of collecting and disposing the condensed moisture and a cabinet to house these components. The fan draws air through the refrigerated surface and cools it below its dew point, removing moisture which is collected and led away. The cool air then passes the hot condenser, where it is reheated. With the addition of other radiated heat the air is discharged into the room at a higher temperature but lower relative humidity than when the air entered the unit. Continuous circulation of the room air through the dehumidifier unit gradually reduces the relative humidity in the room.
The CD100 dehumidifier is a rugged reliable drying unit designed to operate effectively over a broad range of temperature and humidity conditions. A powerful and reliable active hot gas defrost system, controlled by an electronic timer, guarantees positive de-icing and thereby optimising operation at low temperatures. The unit incorporates a welded steel chassis and is finished in vinyl coated steel covers for resilience to damage caused by rough handling.

INSTALATION POSITIONING: Position the dehumidifier unit in the center of the room to be conditioned if at all possible. However if a damp patch is particularly apparent the outlet grille should be pointed towards it. NOTE: Both inlet grille and outlet grille of the dehumidifier unit must have clear space around them and not be obstructed in anyway. WIRING: Connect the power mains cable to a 13 Amp power supply. As follows:Brown
Live
Blue
Neutral
Green/Yellow
Earth (ground)
DRAINAGE: Connect a 15mm inside diameter hose to the water outlet pipe. Secure the hose using a worm drive clip. The hose should at no point be raised higher than the outlet pipe. Failure to observe this requirement will result in flooding of the dehumidifier unit. The CD100 may also be fitted with a water pump (optional), which is capable of discharging the condensate water 30ft away from the unit. The water can, therefore, be discharged into a drain some distance away.
OPERATION
The operation of the dehumidifier is to remove moisture from the air by having it condense on the cold tubes of the evaporator coil. The air then passes over the hot condenser coil and returns to the conditioned space slightly warmer and dryer than when it entered the dehumidifier unit. To concentrate drying all doors and windows should be kept closed. Test for Correct Operation WARNING: DO NOT RUN THE MACHINE WITHOUT THE COVERS IN PLACE FOR ANY LONGER THAN NECESSARY. DO NOT REMOVE / REPLACE THE COVERS WITH THE POWER ON
Remove the cover by releasing the retaining bolts and follow the test procedure laid out below:1. Set the adjustable humidistat to maximum. 2. Switch the machine to the on position; this will result in the compressor starting to run and the fan blade starting to rotate. 3. When the compressor has been running for 20 minutes the coils located above the drain tray will be evenly coated in frost. (If the ambient temperature is above 25ºC the coils will be covered in water. 4. After the machine has been running for approximately 50 minutes the unit will automatically enter into defrost. The defrost cycle lasts for approximately 3 minutes; this will result in the frost on the coils melting and dripping into the drainage tray. 5. After the defrost has finished the machine will return to normal operation. 6. Ensure the condensate drains away from the machine. Setting the Adjustable Humidistat The position of the humidistat depends on the application the CD100 is being used for and the conditions within the area to be dried. The worse the conditions within the area then the higher the humidistat should be set (i.e. the machine will run for a longer period of time to ensure all the moisture is reduced sufficiently). As a rough guide the humidistat wants to be set at
approximately 50% for factories and warehouses and for basements or deflooding then the humidistat should be set to approximately 100%. Optional Discharge Pump This is an optional extra as requested at purchase. The pump works automatically and periodically pumps away collected moisture to a drain or container. The pump is capable of discharging water to a vertical height of 30ft. Indicator Panel The CD100 is fitted with an indicator lamp to show when power is available and the unit is switched on, if this does not appear to be functioning correctly then refer to the repairs section. Warnings. •
Due to the high pressures within the refrigeration circuit, under no circumstances must direct heat be applied to the evaporator coil in an attempt to remove the build up of ice. • No attempt should be made to cut open any part of the refrigeration circuit due to high pressures and gas involved. • If the unit is switched off at the mains power supply for any reason, the unit must be allowed to stand at rest for at least three minutes before restarting. Failure to do so may cause the unit to blow the fuses owing to the compressor due to there being a refrigerant imbalance.
ROUTINE MAINTENANCE WARNING: ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN DISCONNECTED BEFORE CARRYING OUT ROUTINE MAINTENACE ON ITEMS 1, 2, 3, AND 4.
To ensure continued full efficiency of the dehumidifier, maintenance procedures should be performed as follows: Removal of the cover is achieved by means of four screws at the sides of the unit at base level. With the cover removed all maintenance can be carried out. 1.
Clean the surface of the evaporator and condenser coils by blowing the dirt out from behind the fins with compressed air. Hold the nozzle of the air hose away from the coil (approx 6”) to avoid damaging the fins. Alternatively, vacuum clean the coils.
WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS
2.
Check that the fan is firmly secured to the motor shaft and that the fan rotates freely. THE FAN IS SEALED FOR LIFE AND DOES NOT NEED LUBRICATING.
3.
To check the refrigerant charge, run the unit for 20 minutes (with humidistat set to maximum) and briefly remove the cover. The evaporator coil should be evenly frost coated across its surface. At temperatures above 25°C, the coil may be covered with droplets of water rather than frost. Partial frosting accompanied by frosting of the thin capillary tubes, indicates loss of refrigerant gas or low charge.
4.
Check all wiring connections.

DRAINAGE: Connect a 15mm inside diameter hose to the water outlet pipe. Secure the hose using a worm drive clip. The hose should at no point be raised higher than the outlet pipe. Failure to observe this requirement will result in flooding of the dehumidifier unit. The CD100 may also be fitted with a water pump (optional), which is capable of discharging the condensate water 30ft away from the unit. The water can, therefore, be discharged into a drain some distance away.
OPERATION
The operation of the dehumidifier is to remove moisture from the air by having it condense on the cold tubes of the evaporator coil. The air then passes over the hot condenser coil and returns to the conditioned space slightly warmer and dryer than when it entered the dehumidifier unit. To concentrate drying all doors and windows should be kept closed. Test for Correct Operation WARNING: DO NOT RUN THE MACHINE WITHOUT THE COVERS IN PLACE FOR ANY LONGER THAN NECESSARY. DO NOT REMOVE / REPLACE THE COVERS WITH THE POWER ON
Remove the cover by releasing the retaining bolts and follow the test procedure laid out below:1. Set the adjustable humidistat to maximum. 2. Switch the machine to the on position; this will result in the compressor starting to run and the fan blade starting to rotate. 3. When the compressor has been running for 20 minutes the coils located above the drain tray will be evenly coated in frost. (If the ambient temperature is above 25ºC the coils will be covered in water. 4. After the machine has been running for approximately 50 minutes the unit will automatically enter into defrost. The defrost cycle lasts for approximately 3 minutes; this will result in the frost on the coils melting and dripping into the drainage tray. 5. After the defrost has finished the machine will return to normal operation. 6. Ensure the condensate drains away from the machine. Setting the Adjustable Humidistat The position of the humidistat depends on the application the CD100 is being used for and the conditions within the area to be dried. The worse the conditions within the area then the higher the humidistat should be set (i.e. the machine will run for a longer period of time to ensure all the moisture is reduced sufficiently). As a rough guide the humidistat wants to be set at
approximately 50% for factories and warehouses and for basements or deflooding then the humidistat should be set to approximately 100%. Optional Discharge Pump This is an optional extra as requested at purchase. The pump works automatically and periodically pumps away collected moisture to a drain or container. The pump is capable of discharging water to a vertical height of 30ft. Indicator Panel The CD100 is fitted with an indicator lamp to show when power is available and the unit is switched on, if this does not appear to be functioning correctly then refer to the repairs section. Warnings. •
Due to the high pressures within the refrigeration circuit, under no circumstances must direct heat be applied to the evaporator coil in an attempt to remove the build up of ice. • No attempt should be made to cut open any part of the refrigeration circuit due to high pressures and gas involved. • If the unit is switched off at the mains power supply for any reason, the unit must be allowed to stand at rest for at least three minutes before restarting. Failure to do so may cause the unit to blow the fuses owing to the compressor due to there being a refrigerant imbalance.
ROUTINE MAINTENANCE WARNING: ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN DISCONNECTED BEFORE CARRYING OUT ROUTINE MAINTENACE ON ITEMS 1, 2, 3, AND 4.
To ensure continued full efficiency of the dehumidifier, maintenance procedures should be performed as follows: Removal of the cover is achieved by means of four screws at the sides of the unit at base level. With the cover removed all maintenance can be carried out. 1.
Clean the surface of the evaporator and condenser coils by blowing the dirt out from behind the fins with compressed air. Hold the nozzle of the air hose away from the coil (approx 6”) to avoid damaging the fins. Alternatively, vacuum clean the coils.
WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS
2.
Check that the fan is firmly secured to the motor shaft and that the fan rotates freely. THE FAN IS SEALED FOR LIFE AND DOES NOT NEED LUBRICATING.
3.
To check the refrigerant charge, run the unit for 20 minutes (with humidistat set to maximum) and briefly remove the cover. The evaporator coil should be evenly frost coated across its surface. At temperatures above 25°C, the coil may be covered with droplets of water rather than frost. Partial frosting accompanied by frosting of the thin capillary tubes, indicates loss of refrigerant gas or low charge.
4.
Check all wiring connections.
IF ANY OF THE PRECEDING PROBLEMS OCCUR, CONTACT THE EBAC SERVICE CENTER PRIOR TO CONTINUED OPERATION OF THE UNIT TO PREVENT PERMANENT DAMAGE.
REPAIRS 1.
Should an electrical component fail, consult the Factory Service Center to obtain the correct replacement part.
2.
If refrigerant gas is lost from the machine, it will be necessary to use a refrigeration technician to correct the fault. Contact the Factory Service Center prior to initiating this action. Any competent refrigeration technician will be able to service the equipment. The following procedure must be used: a. The source of the leak must be determined and corrected. b. The machine recharging.
should
be
thoroughly
evacuated
before
c. The unit must be recharged with refrigerant measured accurately by weight. d. For evacuation and recharging of the machine, use the crimped and brazed charging stub attached to the side of the refrigerant compressor. The charging stub should be crimped and rebrazed after servicing. NEVER allow permanent service valves to be fitted to any part of the circuit. Service valves may leak causing further loss of refrigerant gas. 3.
The refrigerant compressor fitted to the dehumidifier is a durable unit that should give many years of service. Compressor failure can result from the machine losing its refrigerant gas. The compressor can be replaced by a competent refrigeration technician. Failure of the compressor can be confirmed by the following procedure: a. Establish that power is present at the compressor terminals using a voltmeter. b. With the power disconnected, check the continuity of the internal winding by using meter across the compressor terminals. An open circuit indicates that the compressor should be replaced. c. Check that the compressor is not grounded by establishing that a circuit does not exist between the compressor terminals and the shell of the compressor.

UNPACKING Carefully remove the CD100 dehumidifier unit from its transit box and visually check for signs of transit damage. If there is evidence of damage DO NOT attempt to operate the unit, call your supplier for advice. Do not discard the packing; it will be useful when transporting the dehumidifier unit in the future.
INTRODUCTION Dehumidifiers remove moisture from the air that is circulating through the unit. The resulting reduction of relative humidity helps prevent rust, rot, mould, mildew and condensation within the room, shelter or other enclosed spaces where the dehumidifier is used. A dehumidifier consists of a motor-compressor unit, a refrigerant condenser, an air circulating fan, a refrigerated evaporator, a means for collecting and disposing of the condensed moisture and a cabinet to house these components. The fan draws the moist room air through the cold evaporator coil which cools the air below its dew point. Moisture forms on the evaporator and is collected in the condensate tray then lead away to a permanent drain. The cooled air then passes through the hot condenser, where it is re-heated with the same energy removed during the cooling phase and the addition heat derived from the compressor. The air is therefore discharged into the room at a slightly higher temperature but at a lower relative humidity than that at which it entered the unit. Continuous circulation of room air through the dehumidifier gradually reduces the relative humidity of the room. The CD100 dehumidifier is a rugged reliable drying unit designed to operate effectively over a broad range of temperature and humidity conditions. A powerful and reliable active hot gas defrost system, controlled by an electronic timer, guarantees positive de-icing, thereby optimizing at low temperatures. The unit incorporates a welded steel chassis and is finished in vinyl coated steel covers for resilience to damage caused by rough handling.

UNPACKING Carefully remove the CD200 dehumidifier unit from its transit packaging and visually check for signs of transit damage. If there is evidence of damage DO NOT attempt to operate the unit, call your supplier for advice. Do not discard the packing, it will be useful when transporting the dehumidifier unit in the future.
INTRODUCTION The Ebac CD200 industrial dehumidifier removes moisture from the air through the refrigeration process. The Ebac CD200 is basically comprised of: 1) A compressor 2) A refrigerant evaporator coil 3) A refrigerant condenser coil 4) One circulation fan 5) A humidistat 6) A condensate pump 7) A cabinet to house the above components The fan draws the moist air through the cold evaporator coil which cools the air below its dew point. Moisture forms on the evaporator coil and is collected in the condensate tray which is equipped with a permanent drain. The cooled air then passes through the hot condenser coil where it is reheated using the same energy removed during the cooling phase, plus the additional heat generated by the compressor. The air is therefore discharged from the dehumidifier at a slightly higher temperature with a lower absolute humidity than with which it entered. Continuous circulation of air through the dehumidifier gradually reduces the relative humidity within the area. The CD200 dehumidifier is a rugged, reliable drying unit designed to operate effectively over a broad range of temperature and humidity conditions. The CD200 dehumidifier uses an adjustable humidistat to enable you to select the level of dryness.

INSTALLATION POSITIONING: Position the dehumidifier unit in the center of the room to be conditioned if at all possible. However if a damp patch is particularly apparent the outlet grille should be pointed towards it if possible. This unit can also be used in a duct system where applicable, please see the diagrams on the following pages which identify the overall sizes of the unit and also the mounting points. NOTE: Both inlet grille and outlet grille of the dehumidifier unit must have clear space around them and not be obstructed in anyway.
This unit should be connected to a single outlet circuit fused spur with a 20A rating. Selecting the correct fan speed – The CD200 has a low fan speed and a high fan speed and the required speed must be chosen before installation. To select the correct fan speed firstly remove the filter cover via the 9off screws, then remove the electrical box cover via the 4off M4 hex head bolts. Once the electrical box cover is removed the supplied link wire must be wired between either the ‘C’ and ‘L’ or the ‘C’ and ‘H’ terminals on the terminal block. This is shown below. The default setting of the unit is high speed.
OPERATION The following procedures should be followed to test the CD200 for correct operation: 1) After unpacking, examine all external features to confirm damage-free shipment. Report all defects and damage at once. Connect the power cable to a grounded power source. 2) Install drain tubing as required (detailed in step F). Caution: Do not operate the machine without the covers for any longer than necessary. Do not remove/ replace the covers when the unit is in operation. Check dehumidification process as follows: A. Place unit on a level surface. B. Start up unit as follows: i.Ensure fan speed selection has been chosen as mentioned in previous pages. ii.Rotate humidistat control knob to fully counter clockwise, minimum setting. iii.Plug unit into power supply, switch unit on via on/off switch and rotate humidistat knob clockwise to desired setting. C. Check that the compressor is running. D. Leave the machine running for 15 minutes. E. Observe the evaporator coils behind the filter on the air inlet end of the unit to confirm frost formation. i.If the air temperature is below 70ºF, an even coating of frost should cover the entire evaporator coil, except for the last one or two coils. ii.If the air temperature is about 70ºF, frost and/or droplets of condensed water should cover the entire evaporator coil. F. As the drain tray fills, the condensate will automatically drain by gravity into the condensate pump. Using the supplied hose fit one end to the drainage outlet and secure and the other end of the hose must be located to a permanent drain. The pump has a lift capacity of 5 meters therefore ensure the attached hose is no more than 5 meters above the unit outlet point. If after carrying out the above procedures, the unit does not appear to function properly, refer to the Trouble Shooting section or contact the Factory Service Center. WARNING: • •
Due to the high pressures within the refrigeration circuit, under no circumstances must direct heat be applied to the evaporator coil in an attempt to remove the build up of ice. No attempt should be made to cut open any part of the refrigeration circuit due to high pressures and gas involved. If the unit is switched off at the mains power supply for any reason, the unit must be allowed to stand at rest for at least five minutes before restarting. Failure to do so may cause the unit to blow the fuses owing to the compressor due to there being a refrigerant imbalance.
External Humidistat Option The CD200 has the option of using an external humidistat remotely mounted within a room, where available. In the control box there is a connector that can be wired to, which will enable the use of an external humidistat. The following steps should be carried out to enable correct operation of the external humidistat. • • • • • •
Locate the control box and remove the cover, keeping screws for re-attachment Locate the connector within the control box and remove the plug from the socket Dismantle the plug and remove the link wire from terminals 2 & 3 Wire remote humidistat to terminals 1 & 3, ensuring wires pass through the plug back shell Re-assemble the plug and refit to the socket on the control box The CD200 internal humidistat will now be by-passed and the external humidistat will control the unit.
ROUTINE MAINTENANCE
WARNING: ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN DISCONNECTED BEFORE CARRYING OUT ROUTINE MAINTENANCE ON ITEMS 1, 2, 4, 5, AND 6.
To ensure continued full efficiency of the dehumidifier, maintenance procedures should be performed as follows:
1.
Clean the surface of the evaporator and condenser coils by blowing the dirt out from behind the fins with compressed air. Hold the nozzle of the air hose away from the coil (approx 6”) to avoid damaging the fins. Alternatively, vacuum clean the coils.
WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS.
2.
Check that the fan is firmly secured to the motor shaft and that the fan rotates freely. The fan motor is sealed for life and therefore does not need oiling.
3.
To check the refrigerant charge, run the unit for 15 minutes and briefly remove the cover. The evaporator coil should be evenly frost coated across its surface. At temperatures above 70°F, the coil may be covered with droplets of water rather than frost. Partial frosting accompanied by frosting of the thin capillary tubes, indicates loss of refrigerant gas or low charge.
4.
Check all wiring connections.
IF ANY OF THE PRECEDING PROBLEMS OCCUR, CONTACT THE EBAC SERVICE CENTER PRIOR TO CONTINUED OPERATION OF THE UNIT TO PREVENT PERMANENT DAMAGE.

UNPACKING Carefully remove the CD425 dehumidifier unit from its packing and visually check for signs of transit damage. If there is evidence of damage DO NOT attempt to operate the unit, call your supplier for advice. Do not discard the packing, as it will be useful when transporting the dehumidifier unit in the future.
INTRODUCTION The Ebac CD425 dehumidifier removes moisture from the air that circulates through it. The resulting reduction in relative humidity protects buildings and their contents from the adverse effects of excess humidity. The CD425 Dehumidifier comprises of: a) b) c) d) e) f)
A compressor Refrigerant evaporator coils Refrigerant condenser coils Circulation fan A drain tray for collecting and disposing of condensed moisture A cabinet to house the above components.
The fan draws the moist air through the evaporator coils which cools the air below its dew point. Moisture forms on the evaporator and is collected in the condensate tray which leads away to a permanent drain. The cooled air then passes through the hot condenser, where it is reheated using the same energy removed during the cooling phase and the additional heat generated by the compressor. The air is, therefore, discharged from the dehumidifier at a slightly higher temperature, but a lower relative humidity, than that at which it entered. Continuous circulation of air through the dehumidifier gradually reduces the relative humidity within the area being dehumidified. Where large amounts of moisture are required to be removed from the area, more than one dehumidifier may be required, please contact your local distributor for advice.

OPERATION The CD425 is a self contained low temperature dehumidifier. All electrical contactors, overloads, etc are housed in an electrical box built inside the unit. The unit is equipped with a defrost valve which energized automatically to clear any ice formation on the evaporator coils. This allows the unit to operate at much lower temperatures; the control panel gives indication of the set humidity, drying and defrost status. TEST FOR CORRECT OPERATION The following procedure should be followed to test the unit for correct operation. 1. After unpacking connect the unit to a 220V 3PH 60 Hz – 3 wire power supply. 2. Switch fan ON and check for correct fan rotation. (Air blows out of the top of the machine). 3. Check dehumidification process: a) Remove the front cover b) Check the actual relative humidity inside the area c) Set humidity control to a LOWER value than the actual relative humidity d) After approximately 6 minutes check the compressor is running e) Leave the machine to run for 15 minutes. (NOTE: ensure that the set humidity, see c above, is set very low as the compressor will switch off when the actual RH coincides with the set point) f) Observe the evaporator coils i. If the air temperature is below 20ºC an even coating of ice should cover the entire evaporator coil ii. If the temperature is above 20ºC droplets of condensed water should cover the entire evaporator coil 4. If the air temperature is below 20 ºC the unit will go into defrost within 60 minutes. During the defrost cycle the defrost solenoid valve is energized and a warming of the evaporator coil can be felt.
If after carrying out the above checks the unit does not appear to function correctly refer to the repairs section or your supplier.
SYSTEM INSALLATION POSITIONING Position the CD425 in the area leaving enough room either end of the unit to allow for easy servicing. Using a spirit level ensure the level in both direction. Failure to do so may result in the drain tray overflowing and flooding of the chamber. WIRING Connect a suitably fused 3 phase mains power supply to the MAINS T/B terminal block inside the electrical box located at the control panel end of the machine. DRAINAGE Connect the outlet from the drain tray (located behind the front grille and under the evaporator coils) to a permanent drain. Please ensure that the drainage does not rise above the level of the CD425’s drain tray. Failure to observe this requirement will result in internal flooding of the dehumidifier.
ROUTINE MAINTENANCE WARNING: ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN DISCONNECTED BEFORE CARRYING OUT ROUTINE MAINTENACE ON ITEMS 1, 2, 3, 4, AND 5.
To ensure continued full efficiency of the dehumidifier, maintenance procedures should be performed as follows: 1. Clean the surface of the evaporator and condenser coils by blowing the dirt out from behind the fins with compressed air. Hold the nozzle of the air hose away from the coil (approx 6”) to avoid damaging the fins. Alternatively, vacuum clean the coils.
WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS
2.
Check that the fan is firmly secured to the motor shaft and that the fan rotates freely. The fan motor is sealed for life and therefore does not need oiling.
3.
To check the refrigerant charge, run the unit for 15 minutes and briefly remove the cover. The evaporator coil should be evenly frost coated across its surface. At temperatures above 25°C, the coil may be covered with droplets of water rather than frost. Partial frosting accompanied by frosting of the thin capillary tubes, indicates loss of refrigerant gas or low charge.
4.
Check all wiring connections.
5.
To check the operation of the defrost system, ensure the air temperature is below 20 ºC, switch the machine on and leave it running for approximately 1 hour. The machine will then enter “Hot Gas” defrost mode for approximately 5 minutes before returning to normal operation. If the unit will not defrost, the printed circuit timer board/sensor may be defective or the by-pass valve may be inoperable.
IF ANY OF THE PRECEDING PROBLEMS OCCUR, CONTACT THE EBAC SERVICE CENTER PRIOR TO CONTINUED OPERATION OF THE UNIT TO PREVENT PERMANENT DAMAGE.

INTRODUCTION Dehumidifiers remove moisture from the air that is circulating through the unit. The resulting reduction of relative humidity helps prevent rust, rot, mould, mildew and condensation within the room, or other enclosed spaces where the dehumidifier is used.
A dehumidifier consists of a motor-compressor unit, a refrigerant condenser, an air circulating fan, a refrigerated surface, a means of collecting and disposing the condensed moisture and a cabinet to house these components.
The fan draws air through the refrigerated surface and cools it below its dew point, removing moisture which is collected and led away. The cool air then passes the hot condenser, where it is reheated. With the addition of other radiated heat the air is discharged into the room at a higher temperature but lower relative humidity than when the air entered the unit. Continuous circulation of the room air through the dehumidifier unit gradually reduces the relative humidity in the room.
The CD425 is a self contained low temperature dehumidifier. All electrical contactors, overloads, etc, are housed in an electrical box built inside the unit. The unit is equipped with a defrost valve which energises every 42 minutes to clear any ice formation on the evaporator coils. This allows the unit to operate at much lower temperatures. The control panel gives indication of the set humidity, drying and defrosts status.
The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

DRAINAGE: Connect the outlet from the drain tray (located behind the front grille and under the evaporator coils) to a permanent drain. Please ensure that the drainage does not rise above the level of the CD425’s drain tray. Failure to observe this requirement will result in internal flooding of the dehumidifier unit.
OPERATION The operation of the dehumidifier is to remove moisture from the air by having it condense on the cold tubes of the evaporator coil. The air then passes over the hot condenser coil and returns to the conditioned space slightly warmer and dryer than when it entered the dehumidifier unit. To concentrate drying all doors and windows should be kept closed. Test for Correct Operation WARNING: DO NOT RUN THE MACHINE WITHOUT THE COVERS IN PLACE FOR ANY LONGER THAN NECESSARY. DO NOT REMOVE/REPLACE THE COVERS WITH THE POWER ON.
1. After unpacking connect the unit to a 380/415V, 3Ph, 50Hz – 4 wire power supply 2. Switch the machine to the on position and check for correct fan rotation. (Air blows out of the top of the machine). 3. Check dehumidification process: a) Remove front cover b) Check actual relative humidity inside the area c) Set humidity control to a lower value than the actual relative humidity d) After approximately 6 minutes check the compressor is running e) Leave the machine to run for 15 minutes. (NOTE: ensure that the set humidity, see c) above, is set very low as the compressor will switch off when the actual RH coincides with the set point) f) Observe the evaporator coils i) If the air temperature is below 20°C, an even coating of ice should cover the entire evaporator coil ii) If the temperature is above 20°C, droplets of condensed water should cover the entire evaporator coil. 4. Leave the unit to run for a further 27 minutes, after which the unit should go through a 4 minute defrost cycle. During the defrost cycle the defrost solenoid valve is energized and a warming of the evaporator coil can be felt. If after carrying out the above checks the unit does not appear to function correctly, refer to your supplier.
ROUTINE MAINTENANCE WARNING: ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN DISCONNECTED BEFORE CARRYING OUT ROUTINE MAINTENACE ON ITEMS 1, 2, 3, 4, 5, 6, AND 7.
To ensure continued full efficiency of the dehumidifier, maintenance procedures should be performed as follows: 1. Clean the surface of the evaporator and condenser coils by blowing the dirt out from behind the fins with compressed air. Hold the nozzle of the air hose away from the coil (approx 6”) to avoid damaging the fins. Alternatively, vacuum clean the coils. WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS Check that the fan is firmly secured to the motor shaft and that the fan rotates freely. THE FAN IS SEALED FOR LIFE AND DOES NOT NEED LUBRICATING. 3.
To check the refrigerant charge, run the unit for 15 minutes (with humidistat set to maximum) and briefly remove the cover. The evaporator coil should be evenly frost coated across its surface. At temperatures above 20°C, the coil may be covered with droplets of water rather than frost. Partial frosting accompanied by frosting of the thin capillary tubes, indicates loss of refrigerant gas or low charge.
4.
Check all wiring connections.
5.
The bolts retaining the compressor and fan should be inspected to ensure they have not become loose. Check the insulation sleeves on the refrigeration Pipe work have not become detached.
6.
Inspect the drain tray for water marking. If marking is excessive check the drain pipe for blockage.
7.
To check the operation of the defrost system, switch the machine on and leave it running for approximately 55 minutes in temperatures below 20°C. The machine will then enter defrost mode for approximately 5 minutes, before returning to normal operation. If the unit will not defrost, replace the printed circuit board. If the machine is still not defrosting, replace the by-pass valve. Check the machine again after a further hour of operation to determine that the valve is working correctly.
IF ANY OF THE PRECEDING PROBLEMS OCCUR, CONTACT THE EBAC SERVICE CENTER PRIOR TO CONTINUED OPERATION OF THE UNIT TO PREVENT PERMANENT DAMAGE.

The compressor can be replaced by a competent refrigeration technician. Failure of the compressor can be confirmed by the following procedure: a. Establish that power is present at the compressor terminals using a voltmeter. b. With the power disconnected, check the continuity of the internal winding by using meter across the compressor terminals. An open circuit indicates that the compressor should be replaced. c. Check that the compressor is not grounded by establishing that a circuit does not exist between the compressor terminals and the shell of the compressor.

UNPACKING Thank you for deciding to purchase an Ebac dehumidifier. Like the many tens of thousands of people who have already bought an Ebac dehumidifier we are confident you will find it is the most effective answer to the problem of condensation and dampness related problems Carefully remove the HGR1500 dehumidifier unit from its transit box and visually check for signs of transit damage. If there is evidence of damage DO NOT attempt to operate the unit, call your supplier for advice. Do not discard the packing; it will be useful when transporting the dehumidifier unit in the future. Your dehumidifier is packed in a plastic wrapping, please ensure that it is disposed of safely and where it will not be a danger to children.
INTRODUCTION This user manual tells you how to use the HGR1500 dehumidifier. Please read it thoroughly before operating the dehumidifier. If you have any questions about the unit please contact our Customer Services Department at the address shown at the back of the section or phone 01388 664400. Dehumidifiers remove moisture from the air circulating through it. Continuous operation reduces the relative humidity the air and this helps prevent rust, rot, mould, mildew and condensation. The HGR1500 dehumidifier consists of an air to air heat exchange, motor, compressor unit, a refrigerant condenser and air circulating fan, a refrigerated surface, a means for collecting and disposing of the condensed moisture and a cabinet to house these components.
GENERAL The HGR1500 dehumidifier must only be stored and transported in the horizontal position. To operate, stand the unit on level ground, and connect power supply and it is ready for operation. When a generator is used to supply the power, it is essential to check the minimum kva required in the technical section within this manual. The generator must be started before connection is made to the dehumidifier.
OPERATION The fan draws the moist air through the refrigerated surfaces which cools it below its dew point, removing moisture which is collected and lead away. The cool air then passes over the hot condenser, where it is repeated. With the addition of other radiated heat the air is discharged into the room at a higher temperature but a lower relative humidity than when it entered the unit. Continuous circulation of the room air through the dehumidifier unit gradually reduces the relative humidity in the room. The HGR1500 dehumidifier is a robust, compact unit designed to control the humidity in the enclosed space in which it is placed. The unit is thermally protected and will switch off for a period if maximum operating temperature of 40ºC is exceeded.
ELECTRICAL CONNECTIONS WARNING THIS APPLIANCE MUST BE EARTHED WIRING: Connect the power mains cable/plug of the dehumidifier unit as follows:Brown Blue Green/Yellow
Live Neutral Earth (ground)
As the colour of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminal in your own plug, proceed as follows. The wire which is coloured Green and Yellow must be connected to the terminal marked E or by the Earth symbol or coloured Green or Green and Yellow. The wire which is coloured Blue must be connected to the terminal in the plug which is marked the letters N or coloured Black. The wire which is coloured Brown must be connected to the terminal which is marked with the letter L or coloured Red. You must safely dispose of the non re-wireable plug once it has been removed from the flexible cord. It is dangerous to attempt to insert the plug into any electrical socket. CHANGING THE FUSE 13 Amp fuses that are ASTA approved to BS1362 should only be used. NON REWIREABLE PLUGS The fuse cover must be refitted after the replacement of the fuse.
BASIC STEPS FOR DRYING Ensure that all External doors and windows are closed. Where no doors or windows are fitted, temporarily screen off the openings. POSITIONING For small areas position centrally in the area to be dried, for larger areas such as open plan buildings, offices or factories, a number of dryers may be required, in such cases they should be spaced evenly around the area. Ensure that no unit is positioned in such a way that it blows directly into another. For private houses or flats, position the dryer on one floor at a time, starting at the lowest floor, closing all internal doors on the floor previously dried. Continue until all floor levels have been dried. Note when a particular damp patch is to be dried out the air outlet grille should be directed towards that area but should never be closer than 1m to the surface. At no time should the inlet or outlet grilles be covered or obstructed. DRAINAGE Under most operating conditions water will be produced continuously and it is important that it is drained away correctly and not allowed to spill. Any spillage will evaporate and will therefore, have to be recycled through the dryer again, which in effect, only prolongs the drying period. PORTABLE CONTAINERS Position a closed top container underneath the water discharge pipe (approximately 25 litres capacity). Place a short length of pipe one end over the discharge pipe and the other end in the container. Use a transparent container, this will enable you to check the level of water and so prevent overflowing. As the unit will be running for long periods of time, a regular check should be made on the container water level. PERMANENT DRAINAGE Connect a flexible hose to the water drainage pipe of sufficient length so that it will reach a permanent drain. The gravity head created will allow for a gradual fall from the unit to the drain. Ensure that the hose is free of kinks and is not allowed to rise at any point above the level of the discharge point from the dehumidifier. Any air locks which may be created, should the level be raised by the hose passing over obstructions, could cause the water to “back up” the hose and spill from the drier.
SWITCHING ON Plug the unit into the power supply and switch on. Set the illuminated Rocker switch to the ON SWITCHING OFF Set the illuminated Rocker switch to the OFF position. Turn off the power supply and disconnect.
SPECIAL FEATURES DEFROST OPERATION If the ambient temperature of the room in which the dehumidifier is conditioning, falls below 15ºC ice will form on the evaporator coil as the air passes over it. Over a period of time this build up of ice will effect the efficiency of the dehumidifier on its ability to maintain the required set conditions within the room. The HGR1500 is therefore fitted with a defrost control device. When the unit is operated in ambient of less than 15°C, a defrost cycle should occur approximately every hour. The exact time is impossible to predict as the unit is fitted with a temperature sensitive defrost control. During the defrost cycle the high pressure hot gas from the compressor is diverted into the evaporator coil where it melts the ice which has formed on the evaporator coil.
SAFETY • DO NOT Use the unit if the cabinet or power cord is damaged. • DO NOT Insert objects into any of the grilles on the machine. • DO NOT Cover or obstruct airflow from the grilles. • DO NOT Operate the unit with the covers removed. • DO NOT Attempt any repairs should the unit fail to operate. • DO NOT Stand on the unit. • DO NOT Attempt to lift heavy units unassisted. • DO Check the plug on the equipment matches the supply. • DO Use this unit for the purpose for which it was designed. • DO Ensure the power cord and supply is earthed correctly. • DO Check the voltage selection before attempting to power up the unit. (Dual voltage units only) • DO Use a Residual Current Device “RCD” where possible.
SERVICE The machine should be serviced by qualified Ebac personnel or other persons having technical competence in servicing refrigeration equipment following the instructions in the Ebac service manual.
SPARES Full spares parts listings and Ebac Service Manuals are available upon request by contacting one of the Ebac Service Centres listed in this manual.
OZONE FRIENDLY The gas which is inside the hermetically sealed refrigeration circuit is R22, which is an HCFC. Under No circumstances should this gas be released into the atmosphere. The unit should be serviced by trained personnel who will reclaim the removed gas.
DISPOSAL OF UNIT At the end of the machines working life the refrigerant must be disposed of in the correct manner.
