GENERAL INFORMATION The AT100S is a Low Grain Refrigerant (LGR) Dehumidifier, which is used to remove moisture from air within a building envelope. The dried air will then extract moisture from wetted building materials and building contents by circulating the dry air. “Low Grain” refers to the unit’s ability to remove moisture from air that is already very dry, as one grain of moisture represents 1/7000th of a pound of water. “Refrigerant” refers to the principle of dehumidification. We use vapor compression principles using refrigerant, as opposed to other approaches to dehumidification, such as desiccant drying. The standard rating point for rating the performance of a dehumidifier is 80ºF at 60% Relative Humidity. This corresponds to a Specific Humidity of 92.5 grains of moisture per pound of dry air if measured at sea level. What sets LGR dehumidifiers apart from standard dehumidifiers is that they are capable of removing water from air at 80ºF at 20% Relative Humidity, which is very dry. This corresponds to 30.4 grains of moisture per pound of dry air if measured at sea level. The unit draws air in through the grille located in the top of the unit. The air is dehumidified as it moves through the various stages within the unit, as depicted in Figure 1. The dehumidified air is then discharged out the front of the unit, close to the floor. Water removed from the air is delivered to an automatically controlled pump within the unit, which provides the pressure to pump the water to a remote location via 35 feet of vinyl tubing supplied. The maximum allowable lift to maintain an acceptable rate of flow from the pump is 19 feet. The maximum lift at zero flow at rated voltage is 20 feet. As the inlet air temperature and/or humidity drops, a point will be reached where the surface temperature of the evaporator will be below freezing and the water will accumulate as frost on the evaporator surface. Periodic defrosting will be required to melt the frost and to direct the water run-off to the pump. As to when defrosting takes place, this is automatically determined and controlled by the unit. The AT100S can be operated in environments between 33°F and 100°F (0.6 and 38°C). Within this temperature range, the unit will regulate its operation as necessary, depending on conditions. Below 40°F, the unit may continue to dehumidify effectively, depending on the humidity load. For example, if the air temperature is 34°F (1°C), but the air is very dry, the unit will operate for a few minutes, and then shut down on the “too cold” alarm. However, if the space can be warmed with heaters, with air being circulated by fans, it will greatly speed up the drying process by increasing the evaporation rate of water out of the building materials. Optimal drying temperatures range somewhere between 66 and 85°F (19 and 29.5°C). TRANSPORTING THE AT100S The AT100S should be transported upright. When transporting the unit, there is the possibility of water spillage out of the pump reservoir or water drainage off of the wetted evaporator coil. It is therefore important to make effective use of the manual purge button to evacuate the water out of the pump reservoir before moving the unit. After the OFF button has been depressed, it is recommended that a manual purge be initiated by depressing the PURGE button. Then wait at least 15 minutes for the water to shed off the evaporator and find its way into the pump reservoir. Initiate another manual purge to clear the pump reservoir of any residual water one last time before moving the unit. Disconnect and fully drain the 35 foot vinyl drain hose before coiling it up and storing it under the top cover.

CAUTION: If the unit has been laid on its back, even for short periods of time, it must be set upright for at least ½ hour before being plugged in and started up. This gives the compressor oil and liquid refrigerant sufficient time to re-distribute. Failure to do so can cause premature compressor failure, and voids the compressor warranty. If extremely poor road conditions exist, or excessive shock and vibration are expected, take precautionary measures by padding the unit to provide impact absorption during transport. CAUTION: Always be careful when moving the AT100S inside a building or home. The unit weighs 125 lbs., so older structures with weakened floors and staircases may require special considerations for safe transport. ELECTRICAL REQUIREMENTS The AT100S is a cord-connected unit that uses a standard grounded NEMA 5-15P plug which is to be connected to a 115 Volt AC 60 Hz grounded electrical receptacle. The supply voltage should be between 109 and 121 Volts in order for the unit to function as intended. Performance ratings are determined at 115 Volts. In circumstances where extreme voltage fluctuations exist, and have not yet been corrected by the electrical utility, the unit is capable of operating between 104 and 126 volts, when necessary. Due to momentary start-up current surge, the unit may require a dedicated 15 Amp circuit which is free of other loads. There is a 0 to 10 second random re-start sequence built into the control logic that prevents simultaneous start-up of multiple units after a power outage and subsequent re-energization. If the unit was in operation before a power outage, it will be re-started automatically, but randomly within 10 seconds, when power resumes. It is recommended that a Ground Fault Current Interrupt (GFCI) device be used in the electrical supply circuit. A GFCI is an electrical safety device that will trip the circuit and interrupt the supply of electricity if leakage of current is detected. Extension cords used for the AT100S must be Certified (UL, CSA as applicable) heavy duty No. 14/3 AWG grounded industrial-grade type. Use of larger numerical gauge (smaller diameter wire) wire power cord(s) may result in electric shock, fire hazards, and/or damage to the unit. The cords must be in good condition, in continuous lengths (no splicing) and should not exceed a length of 50 feet. Make certain that any extension cords used do not reduce power at the unit to less than the recommended 109 Volts. Use of a voltmeter to confirm voltage is suggested. Check to ensure that any circuit to which the unit is connected is protected by a maximum 20 Amp circuit breaker. To avoid personal injury, fire hazards and/or damage to the AT100S electrical system and power cord, do not connect or disconnect the power cord to an electrical outlet unless the unit is “OFF”. REQUIREMENTS FOR SAFE OPERATION Never allow unauthorized individuals or children to operate the unit at any time. Abatement Technologies urges anyone operating the AT100S to wear the proper personal protective equipment and follow safe work practices in accordance with federal, state, provincial and employer regulations. 3 of 10
Check the condition of power cord(s) before using them. Damaged cords can cause fatal electric shock and/or equipment damage. Power cord(s) should never be exposed to water, heat, sharp, or abrasive objects; in addition, they should never be kinked or crushed. Avoid tightly wrapping the cords to prevent kinking of the internal wires. Always replace damaged power cords immediately. Never pull the unit by the power cord. Avoid running over power cords with utility equipment and vehicles. CAUTION: As with any piece of electrical equipment, always make sure that the unit is turned “OFF” prior to disconnecting it from an electrical outlet. Failure to do so will cause “arcing”, and could result in personal injury, fire hazards and/or damage to the unit. Do not disconnect the power cord from supply receptacle while the unit is operating. WARNING: To reduce risk of electrical shock, do not expose this unit to water or rain – it is certified for INDOOR USE ONLY. Do not touch the electrical outlet or power cord(s) with wet hands or while standing on a wet or damp surface. WARNING: Risk of electrical shock, or contact with moving parts leading to personal injury or death! Turn unit “OFF” and disconnect power cord from supply receptacle before taking off any removable covers. WARNING: The AT100S is equipped with an automatic reset / restart motorized impeller that will restart without warning after a temporary power interruption or recovery from a thermal overload (over-heating) condition. If all covers are not in place, the intended protection from the motorized impeller will not be present - keep clear of the motorized impeller to reduce the risk of injury. WARNING: To reduce risk of fire or electrical shock, do not use the AT100S with any solid-state speed control device. CAUTION: For general dehumidification use only. Do not use to dehumidify hazardous or explosive materials and vapors. WARNING: Abatement Technologies AT100S dehumidifier is not intrinsically safe for use in hazardous environments.

WARNING: Pressurized Unit. This equipment is factory-charged with refrigerant R-22 and is under pressure. Only qualified personnel should attempt repairs to the refrigeration system. Do not puncture or cut into the refrigeration piping. WARNING: The unit should never be operated without the compressor terminal cover properly secured in place on top of the compressor; otherwise, serious injury or death could result. The cover is required to be securely in place to allow proper operation for the safety overload, and to act as a shield if the hermetic terminals blow out of the compressor shell. AT100S CONTROL PANEL LCD Display – The scrolling 2-line Liquid Crystal Display (LCD) is the primary communication device to the user. ON/OFF Button – Turns the dehumidifier ON by pressing once, and then OFF by pressing again. MENU Button – Each press of the button cycles the LCD through its secondary functions in the following order; Job Hours, Total Hours, then Language Setting. The MENU button is also used to confirm a change after having navigated to the desired choice using the ENTER button. Job Hours – Indicates the number of hours that the unit has been operating since it was last reset to zero. To reset Job Hours to zero, depress the ENTER button. Total Hours - Indicates the number of hours that the unit has been operating since it was new. Language Setting – Each press of the ENTER button cycles through the following languages on the LCD; ENGLISH, SPANISH, FRENCH. Press MENU to confirm the choice of language. ENTER Button – After the MENU button has been pressed, each press of the ENTER button cycles through the various options that can be changed. Press MENU button to confirm an entry. PURGE Button – Forces the pump to drain the pump reservoir of any remaining water. Pressing the PURGE button initiates a 60 second manual purge. It is especially useful after the unit has been shut off, but water continues to drain off the evaporator. The unit can then be given a final manual purge before it is moved. Normal Operation Indicator - Green LED light that indicates that the unit is “on” and running normally. Defrost Indicator – Blue LED light that indicates that the unit is actively defrosting. Abnormal Operation Indicator – Flashing Red LED light that indicates there is a problem with the unit, usually accompanied by an audible alarm. Refer to the LED display for any messages that may be displayed.

Fault Conditions: Blocked Drain – The Red LED will flash, the audible alarm will sound, and the LCD will display “Blocked Drain”, which indicates the water level in the pump reservoir is abnormally high. This could be due to the following: • • • • • • •
Kinked or pinched drain hose Excessive lift (drain hose higher than 19 feet) Male drain hose fitting is partially or fully disconnected Unit was unplugged, and manual purge was not performed 15 minutes after unit was last shut off. Upon restoration of power, reservoir may be quite full. Pump motor failure Pump main float switch failure Pump discharge hose blocked
Identify and correct the cause, and re-start the unit. Too Cold - The Red LED will flash, the audible alarm will sound, and the LCD will display “Too Cold” which indicates that the ambient temperature conditions are too cold, and/or the humidity load is too low, to either maintain acceptable compressor conditions, or to maintain acceptable complete defrost cycles. FILTER REPLACEMENT The air filter is a high efficiency MERV-8 rated filter and can be easily replaced – please order Part Number AT100-1712. Access to the air filter is provided by opening the hinged inlet grille. Pry up one side of the filter skirt with a finger, and then remove the entire filter. As long as the unit has not been tampered with, and all panels are in place, the unit has been designed to allow the filter to be changed without exposing the operator to mechanical or electrical hazards. The original equipment high efficiency pleated air filter is rated MERV-8, and has been specifically designed to allow the unit to remain clean internally, and perform to published ratings. The filters are not reusable, therefore please do not attempt to clean and reuse them. Replacement frequency is very subjective, as it depends on the cleanliness of the job site air, as well the duration of use. CAUTION: Abatement Technologies AT100S units are designed to meet or exceed safety and performance standards for LGR dehumidification equipment. Use only Abatement Technologies genuine parts, including replacement filters. Use of non-Abatement Technologies parts, including replacement filters voids the product warranty and all performance claims. EXTERNAL DUCTING External ducting can be applied to the optional 10” dehumidifier air discharge collar. The ducting enables the dry air to be discharged to a location more remote from the unit’s air intake for those instances where it is advantageous to do so. The maximum duct length will depend on the type of ducting used, but in any case, should not cause the pressure at the outlet, external to the unit, to exceed 0.15” water column external static pressure.

ACCESS TO CLEANING Periodically, the evaporator coil, condenser coil, air-to-air heat exchanger, drain pan and drain tube will need to be cleaned. The frequency of cleaning is indeterminate and depends on how often the equipment is used and how dirty the operating environment has been. The front and side panel is one large L-shaped piece which, when removed, gives access to the internal compartments for cleaning. To Obtain Access for Cleaning: WARNING: UNPLUG THE UNIT FROM THE POWER SUPPLY BEFORE REMOVING ANY COVERS. FAILURE TO DO SO COULD RESULT IN PERSONAL INJURY OR DEATH. • • • •

Remove the front/right side panel Remove the four screws holding the Air-to-Air-Heat Exchanger Cover Plate in place (see Fig. 1) and then remove the Cover Plate. Open the top panel and remove the air filter – you should now be able to see the plates of the plastic Air-to-Air-Heat Exchanger from above. Force a finger between the Heat Exchanger plates, somewhere in the middle of the Heat Exchanger. Push the Heat Exchanger sideways to start removing it from its cavity. Once enough plates start protruding out the side of the casing, grab hold of the Heat Exchanger and pull it completely out of the unit. For cleaning, the Heat Exchanger can be immersed in mild soapy water and then rinsed well. With the Heat Exchanger removed, full access is available to clean the fins of the aluminum evaporator and condenser coils. The dirtiest surfaces to be cleaned will be on the air-entering sides. Vacuuming with a brush should be effective at removing the debris; if not, contact qualified service personnel if more aggressive cleaning is required. There is also full access to clean the Drain Pan, Drain Spout, and Drain Hose. Once complete, ensure that the Air-to-Air-Heat Exchanger is carefully aligned on the 4 rails and is fully inserted into the cavity with the large arrow marking on its side pointing “UP”. Re-install the Cover Plate and the front/right side panel. Be careful not to over-tighten and strip the screws. If a screw strips, replace it with one similar, but the next number size up.
Caution: Poor performance will result if the arrow on the side of the Air-to-Air-Heat Exchanger is not pointing “UP” when it’s re-inserted in the slide rail cavity.
