General Installation Information Unit Location
Safety Considerations
Locate the unit in an indoor area that allows for easy removal of the filter and access panels. Location should have enough space for service personnel to perform maintenance or repair. Provide sufficient room to make water, electrical and duct connection(s). If the unit is located in a confined space, such as a closet, provisions must be made for return air to freely enter the space by means of a louvered door, etc. Any access panel screws that would be difficult to remove after the unit is installed should be removed prior to setting the unit. On horizontal units, allow adequate room below the unit for a condensate drain trap and do not locate the unit above supply piping. Care should be taken when units are located in unconditioned spaces to prevent damage from frozen water lines and excessive heat that could damage electrical components.
WARNING: Before performing service or maintenance operations on a system, turn off main power switches to the indoor unit. If applicable, turn off the accessory heater power switch. Electrical shock could cause personal injury. Installing and servicing heating and air conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install, repair or service heating and air conditioning equipment. Untrained personnel can perform the basic maintenance functions of cleaning coils and cleaning and replacing filters. All other operations should be performed by trained service personnel. When working on heating and air conditioning equipment, observe precautions in the literature, tags and labels attached to the unit and other safety precautions that may apply.
Installing Vertical Units Follow all safety codes. Wear safety glasses and work gloves. Use a quenching cloth for brazing operations and have a fire extinguisher available.
Prior to setting the unit in place, remove and discard the compressor hold down shipping bolt located at the front of the compressor mounting bracket.
Moving and Storage
Vertical units are available in left or right air return configurations. Top flow vertical units should be mounted level on a vibration absorbing pad slightly larger than the base to provide isolation between the unit and the floor. It is not necessary to anchor the unit to the floor (see right).
Move units in the normal “up” orientation. Horizontal units may be moved and stored per the information on the packaging. Do not stack more than three units in total height. Vertical units may be stored one upon another to a maximum height of two units. Do not attempt to move units while stacked. When the equipment is received, all items should be carefully checked against the bill of lading to be sure all crates and cartons have been received. Examine units for shipping damage, removing the units from the packaging if necessary. Units in question should also be internally inspected. If any damage is noted, the carrier should make the proper notation on the delivery receipt, acknowledging the damage.
Bottom flow units should be mounted level and sealed well to floor to prevent air leakage. Bottom flow units require the supply air opening to be cut at least 1/2 in. larger than the unit’s air outlet. Protect the edges of combustible flooring with sheet metal over-wrap or other noncombustible material.

ENVISION COMMERCIAL 0.75-6 TONS INSTALLATION MANUAL
Installing Horizontal Units on the underside of the bottom panel. When attaching the hanger rods to the bracket, a double nut is required since vibration could loosen a single nut. To allow filter access, one bracket on the filter side should be installed 180° from the position shown in the figure below. The unit should be pitched approximately 1/4 in. towards the drain in both directions to facilitate the removal of condensate. Use only the bolts provided in the kit to attach hanger brackets. The use of longer bolts could damage internal parts.
Remove and discard the compressor hold down shipping bolt located at the front of the compressor mounting bracket prior to setting the unit in place. Horizontal units are available with side or end discharge. NOTES: 1) Left (Right) Return Side Discharge cannot be converted to Left (Right) Return End Discharge or vice versa, without additional custom sheet metal parts. Horizontal units are normally suspended from a ceiling by four (009-030 models) or six (036-072 models) 3/8 in. diameter threaded rods. The rods are usually attached to the unit by hanger bracket kits furnished with each unit. 2) In some applications, it is difficult to service the filter with the central hanger bracket, located near the air coil, installed. In these instances, it is permissible to suspend the unit with the five remaining hanger brackets.
Some applications require the installation of horizontal units on an attic floor. In this case, the unit should be set in a full size secondary drain pan on top of a vibration absorbing pad. The secondary drain pan prevents possible condensate overflow or water leakage damage to the ceiling. The secondary drain pan is usually placed on a plywood base isolated from the ceiling joists by additional layers of vibration absorbing material.
Lay out the threaded rods per the dimensions below. Assemble the hangers to the unit as shown. Securely tighten the brackets to the unit using the weld nuts located
CAUTION: Do not use rods smaller than 3/8-inch diameter since they may not be strong enough to support the unit. The rods must be securely anchored to the ceiling.

9 – SW2-8 must be in the OFF position for pulsed “L” lockout signal and in the ON position for constant “L” lockout signal. 10 - Air Flow Configuration Example: SW1 configured for dip 1 as low, dip 3 as medium, and dip 5 as high Speed ECM2 fan 11 – Dual Capacity units only.
4 - The blk/wh and gray/wh wires are removed when Aux Heat is installed . 5 - Buss lugs L1 and L2 can be removed and dual power wire sets connected directly to box lugs L 1, L2, and L3, L4. 6 - This Switch allows the unit to down stage with the t -stat when OFF and finish on second stage when ON. Finish second stage reduces stage changing in recip dual capacity compressors and should be ON for unzoned Dual Cap E -Series or Premier 2 speed units. 7 - When optional electronic air -filter is installed, power for the electronic air-filter is provided by P2-2 and 24 VAC. 8 – SW3-4 should be in the OFF position when using the 17P501A01 electric heat board and should be ON when using the 17P514A01 electric heat board .

ENVISION COMMERCIAL 0.75-6 TONS INSTALLATION MANUAL
Envision Controls - Premier Shutdown Mode A 24VAC common signal to the “shutdown” input on the control board puts the unit into shutdown mode. Compressor, hot water pump and blower operation are suspended.
Safety Controls The Envision control receives separate signals for a high pressure switch for safety, a low pressure switch to prevent loss of charge damage, and a low suction temperature thermistor for freeze sensing. Upon a continuous 30-second measurement of the fault (immediate for high pressure), compressor operation is suspended, the appropriate lockout LED begins flashing. (Refer to the “Fault Retry” section below).
Standard Premier Microprocessor The Premier control system is a microprocessor-based printed circuit board conveniently located in the unit control box for accessibility. The microprocessor control is specifically designed for the Envision Series heat pumps and integrate single speed and dual capacity compressors, variable speed ECM blower motors and advanced features needed in geothermal applications. All variable speed ECM airflow selections are conveniently configured on the control via DIP switches. The microprocessor provides control of the entire unit as well as outputs for status modes, faults, and diagnostics. Removable low voltage thermostat terminal strips provide convenient field connections. LEDs are located on the front of the cabinet for quick inspection without removing any access panels.
Testing The Envision control allows service personnel to shorten most timing delays for faster diagnostics.
Fault Retry All faults (except for low RPM faults with the ECM blower motor) are retried twice before finally locking the unit out. An output signal is made available for a fault LED at the thermostat. The “fault retry” feature is designed to prevent nuisance service calls.
Diagnostics The Envision control board allows all inputs and outputs to be displayed on the LEDs for fast and simple control board diagnosis.
Startup The unit will not operate until all the inputs and safety controls are checked for normal conditions. At first powerup, a four minute delay is employed before the compressor is energized.
Resistance Heat Control (208-230 Units)
Component Sequencing Delays
The electric heat control module contains the appropriate high-voltage control relays. Control signals energize the relays in the proper sequence, and the LED display board indicates which stages are energized.
Components are sequenced and delayed for optimum space conditioning performance.
Heating Operation Heat, 1st Stage (Y1)
Accessory Relay An accessory relay on the control board allows for field connection of solenoid valves, electronic air cleaners, etc. The accessory relay has a normally open output and a normally closed output.
The blower motor is started on low speed immediately (PSC ON), the loop pump is energized 5 seconds after the “Y1” input is received, and the compressor is energized on low capacity 10 seconds after the “Y1” input. The blower is switched to medium speed 15 seconds after “Y1” input (ECM only).
Short Cycle Protection
Heat, 2nd Stage (Y1,Y2) Single-Speed Units
The control employs a minimum “off” time of four minutes to provide for short cycle protection of the compressor.
Blower changes to high speed 15 seconds after the “Y2” input (ECM only).
Condensate Overflow Protection
Heat, 2nd Stage (Y1,Y2) Dual Capacity Units
The Envision control board incorporates an impedance sensing liquid sensor at the top of the drain pan. Upon a continuous 30-second sensing of the condensate, compressor operation is suspended (see Fault Retry), and the condensate overflow lockout LED begins flashing.
The second stage compressor will be activated 5 seconds after receiving a “Y2” input as long as the minimum first stage compressor run time of 1 minute has expired. The ECM blower changes from medium to high speed 15 seconds after the “Y2” input. 29
ENVISION COMMERCIAL 0.75-6 TONS INSTALLATION MANUAL
Envision Controls - Premier cont. NOTE: Blower speed can change automatically only with an ECM Motor.
Heat, 3rd Stage (Y1,Y2,W) Single-Speed Units The first stage of resistance heat is energized 10 seconds after “W” input, and with continuous 3rd stage demand, the additional stages of resistance heat engage sequentially every 5 minutes.
ECM Airflow Selection DIP Switches (SW1) A 12-position DIP switch package on the Envision control allows the airflow levels to be set for low, medium and high speed. (Refer to Blower Performance Data - ECM Motor). Only three of the DIP switches can be in the “on” position. The first “on” switch (the lowest position number) determines the “low speed blower” setting. The second “on” switch determines the “medium speed blower” setting, and the third “on” switch determines the “high speed blower” setting.
Heat, 3rd Stage (Y1,Y2,W) Dual Capacity Units The 1st stage of resistance heat is energized 10 seconds after “W” input, and with continuous 3rd stage demand, the additional stages of resistance heat engage sequentially every 5 minutes.
Emergency Heat (W only) The blower is started on high speed, and the first stage of resistance heat is energized 10 seconds after the “W” input. Continuing demand will engage the additional stages of resistance heat sequentially every 2 minutes.
Lockout Conditions During lockout mode, the appropriate unit and thermostat lockout LEDs will illuminate. The compressor, loop pump, hot water pump, and accessory outputs are de-energized. Unless the lockout is caused by an ECM low RPM fault, the blower will continue to run on low speed. If the thermostat calls for heating, emergency heat operation will occur.
Cooling Operation In all cooling operations, the reversing valve directly tracks the “O” input. Thus, anytime the “O” input is present, the reversing valve will be energized.
All lockout modes can be reset at the thermostat after turning the unit off, then on, which restores normal operation but keeps the unit lockout LED illuminated. Interruption of power to the unit will reset a lockout without a waiting period and clear all lockout LEDs.
Cool, 1st Stage (Y1,O) The blower motor and hot water pump are started immediately, the loop pump(s) is energized 5 seconds after the “Y1” input is received. The compressor will be energized (on low capacity for Dual Capacity units) 10 seconds after the “Y1” input. The ECM blower will shift from low to medium speed 15 seconds after the “Y1” input (85% of medium speed if in dehumidification mode).
High Pressure This lockout mode occurs when the normally closed safety switch is opened momentarily (set at 600 psi).
Low Pressure Cool, 2nd Stage (Y1, Y2, O) Single Speed Units
This lockout mode occurs when the normally closed low pressure switch is opened for 30 continuous seconds (set at 40 psi).
The blower changes to high speed (85% of high speed if in dehumidification mode) 15 seconds after the “Y2” input (ECM only).
Freeze Detection (Water Flow)
Cool, 2nd Stage (Y1, Y2, O) Dual Capacity Units The second stage compressor will be activated 5 seconds after receiving a “Y2” input as long as the minimum first stage compressor run time of 1 minute has expired. The ECM blower changes to high speed 15 seconds after the “Y2” input. (85% of high speed if in dehumidification mode).
This lockout mode occurs when the freeze thermistor temperature is at or below the selected freeze sensing point (well 30°F or loop 15°F) for 30 continuous seconds.
Condensate Overflow
Blower (G only)
This lockout mode occurs when the condensate overflow level has been reached for 30 continuous seconds.
The blower starts on low speed (PSC ON). Regardless of blower input “G” from thermostat, the blower will remain on low speed for 30 seconds at the end of each heating, cooling or emergency heat cycle.
Blower RPM The control board monitors blower RPM to sense operation. This lockout mode occurs if the blower RPM falls below the low RPM limit (100 RPM) for 30 continuous seconds (ECM only).
A DIP switch on the Envision control allows field selection of 15% reduced blower speeds for cooling in the dehumidification mode or medium and high blower speeds for cooling in the normal mode.

Envision Controls - FX10 cont. An optional Medium User Interface (MUI) for control setup and advanced diagnostics is available with some mounting kits, MUIK3 - Panel mount version and the MUIK4 - Wall mount version.
Optional FX10 Microprocessor and BAS S Interface
Zone Sensors There are two options for zone sensors that can be used with the FX10 control. Both sensors use a Johnson controls A99 positive temperature coefficient type sensor. The TAXXJ02 has a set point adjustment now which will give the end user a +/- 5°F adjustment from the set point as well as a push button that can be used for temporary occupancy. The control leaves the factory set to operate with a TAXXJ02 sensor and can be changed to read the TAXXA04 sensor through a building automation system or with a user interface.
The FX10 is a microprocessor based control that not only monitors and controls the heat pump but also can communicate any of this information back to the building automation system (BAS). This means that not only does the control monitor the heat pump at the unit you can also monitor and control many the features over the BAS. This clearly puts the FX10 in a class of its own.
Standard Features • • • • • • • • • •
The control will enumerate all fault conditions (HP, LP, CO, LOC, and Freeze Detection) over a BAS as well as display them on a medium user interface (MUI). HP, LP, CO and Freeze Detection faults can all be reset over a BAS. A Loss Of Charge fault can not be reset or bypassed until the problem has been corrected. A MUI is invaluable as a service tool for the building service team.

DDC Operation and Connection
The unit can be commanded to run by a typical heat pump thermostat or run based on heating and cooling set points supplied by a BAS. The control board is wired with quick connect harnesses for easy field change out of a bad control board. All ECM variable blower speed settings can be changed over a BAS or with a MUI. The control has an input programmed to enable field installed emergency heat in the event that the compressor is locked out. This input can also be commanded on from a BAS as needed. An alarm history can be viewed through the MUI and will be held in memory until the unit is power cycled. Relative humidity can be read by a 0-5VDC humidity sensor that is displayed over the network. If you are using an ECM blower motor the control can enable dehumidification mode based on a set point in the control. The dehumidification set point itself can also be changed over a BAS or with a MUI. Dehumidification mode can also be enabled by the BAS. Because the FX10 is not factory configured to read CO2 levels, contact the factory for application assistance.
Other optional network protocol boards that can be added to the FX10 are: • Johnson Control N2 • LonWorks • BACnet - MS/TP @ 19,200 Baud rate - Limit devices to 30 on a single trunk line.
Control and Safety Feature Details Emergency Shutdown The emergency shutdown mode can be activated by a command from a facility management system or a closed contact on BI-2. The default state for the emergency shutdown data point is off. When the emergency shutdown mode is activated, all outputs will be turned off immediately and will remain off until the emergency shutdown mode is de-activated. The first time the compressor starts after the emergency shutdown mode has been de-activated, there will be a random start delay present.
The FX10 control has unused analog and digital inputs for field installed items such as air temperature, water temperature, CO2 or current status switches. The control has unused binary and PWM outputs that can be commanded over the BAS for field use. 35
ENVISION COMMERCIAL 0.75-6 TONS INSTALLATION MANUAL
Envision Controls - FX10 cont. Lockout Mode
Low Pressure (BI-3)
Lockout mode can be activated by any of the following fault signals: refrigerant system high pressure, refrigerant system low pressure, freeze detection, and condensate overflow. When any valid fault signal remains continuously active for the length of its recognition delay, the controller will go into fault retry mode, which will turn off the compressor. After the Compressor short cycle delay, the compressor will attempt to operate once again. If three consecutive faults occur in 60 minutes during a single heating or cooling demand, the unit will go into lockout mode, turning off the compressor, enabling the alarm output, and setting the blower back to low speed operation until the controller is reset. If the control faults due to the low pressure input (BI-3) being open during the pre-compressor startup check, the control will go into lockout mode immediately, disabling the compressor from starting and enabling the alarm output (BO-6). The lockout condition can be reset by powering down the controller, by a command from the BAS, or by the holding the ESC and Return keys on the MUI for 5 seconds.
The low-pressure switch shall be a normally closed (NC) switch that monitors the systems refrigerant pressure. The input shall be checked 15 seconds before compressor start up to be sure the pressure switch is closed and then ignored for the first 2 minutes after the compressor output (BO-2) is enabled. If the switch is open continuously for (30) seconds during compressor operation the compressor output (BO-2) will be disabled. The compressor will not restart until the compressor short cycle time delay has been satisfied.
Condensate Overflow The condensate overflow sensing circuit will monitor the condensate level as a resistance input to AI-3. If the condensate water level rises resulting in the input resistance rising above the set point for the recognition delay period, the condition will be recognized as a fault. The condensate will be subjected to a (30) second lockout delay which requires that the fault be sensed for a continuous (30) seconds before suspending unit operation.
Alarm Output (BO-6) The alarm output will be enabled when the control is in the lockout mode and will be disabled when the lockout is reset.
Test Mode Raising the zone temperature input (AI-1) reading to 180–220°F or by holding the ESC and down arrow keys on the MUI for 5 seconds will put the control into test mode. In test mode the random start delay and the compressor fixed on delay time will both be shortened to 5 seconds and the reversing valve will be allowed to cycle with out shutting down the compressor. If an MUI is connected to the control LED 8 will flash and the words “Test Mode Enabled” will be shown on the LCD display when the control is in test mode. Test mode will be disabled after a power cycle, 30 minute timeout, or by holding the ESC and Up arrow keys on the MUI.
Freeze Detection (AI-5) The freeze detection sensor will monitor the liquid refrigerant temperature entering the water coil in the heating mode. If the temperature drops below the freeze detection trip point for the recognition delay period, the condition will be recognized as a fault. The freeze detection trip point will be factory set for 30°F and will be field selectable for 15°F by removing a jumper wire on BI-5. The freeze detection fault condition will be bypassed 2 minutes at normal compressor startup, to allow the refrigeration circuit to stabilize. If the freeze detection sensor becomes unreliable at any time compressor operation will immediately be suspended until the problem is corrected. This should be displayed as an alarm on the BAS and the MUI. This alarm will be reported a “Water Low Temp Limit” fault.
Sequence of Operation Power Fail Restart When the controller is first powered up, the outputs will be disabled for a random start delay. The delay is provided to prevent simultaneous starting of multiple heat pumps. Once the timer expires, the controller will operate normally.
High Pressure (BI-11) The high-pressure switch shall be a normally closed (NC) switch that monitors the systems refrigerant pressure. If the input senses the high-pressure switch is open it must disable the compressor output immediately and count the fault. The compressor minimum on time does not apply if the highpressure switch opens. The compressor will not restart until the compressor short cycle time delay has been satisfied. 36

Envision Controls - FX10 cont. medium speed and will operate in high speed when the compressor is operating at full capacity.
Random Start Delay This delay will be used after every power failure, as well as the first time the compressor is started after the control exits the unoccupied mode or the emergency shutdown mode. The delay should not be less than 1 second and not longer than 120 seconds. If the control is in test mode the random start delay will be shortened to 5 seconds.
Thermostat Control Mode In thermostat mode the compressor will be cycled based on Y1 and Y2 calls from a room thermostat. When the control receives a Y1 command (BI-7) from the thermostat the low capacity compressor output (BO2) will be enabled and the ECM blower will operate in medium speed. When the control receives a Y2 command (BI-8) from the thermostat the full capacity compressor output will be enabled and the ECM blower will operate in high speed. During the heating cycle the reversing valve will be commanded into the off position.
Compressor Fixed On Delay Time The Compressor Fixed On Delay Time will ensure that the compressor output (B02) is not enabled for (90) seconds after the control receives a call to start the compressor. This delay is adjustable from 30 – 300 seconds over a BAS or a MUI. If the control is in test mode the Compressor Fixed On Delay Timer will be shortened to 5 seconds.
Cooling Cycle On a call for cooling, the blower enable output and accessory output 2 will turn on immediately after the random start delay timer has been satisfied. If the compressor short cycle time delay has been satisfied, the compressor will turn on after the blower enable and accessory output 2 are on and the fixed compressor start delay timers have been satisfied.
Compressor Minimum On Delay The compressor minimum on delay will ensure that the compressor output is enabled for a minimum of (2) minute each time the compressor output is enabled. This will apply in every instance except in the event the high pressure switch is tripped or emergency shutdown then the compressor output will be disable immediately.
Set Point Control Mode In set point control mode the reversing valve output will be enabled. As the temperature falls below the cooling set point and begins to operate in the cooling proportional band, the low capacity compressor output (BO-2) will be enabled. A PI loop in the programming of the control will determine when the full capacity compressor output (BO-4) is to be enabled. The compressor must be operating in low capacity for a minimum of 30 seconds before the full capacity compressor output can be enabled. During low capacity compressor operation the ECM blower will operate in medium speed and will operate in high speed when the compressor is operating at full capacity.
Compressor Short Cycle Delay Time The compressor short cycle time delay will ensure that the compressor output will not be enabled for a minimum of (5) minutes after it is disabled. This allows for the system refrigerant pressures to equalize after the compressor is disabled.
Heating Cycle On a call for heating, the blower enable output and accessory output 2 will turn on immediately after the random start delay timer has been satisfied. If the compressor short cycle time delay has been satisfied, the compressor will turn on after the blower enable and accessory output 2 are on and the fixed compressor start delay timers have been satisfied.
Thermostat Control Mode In thermostat mode the compressor will be cycled based on Y1 and Y2 calls from a room thermostat. When the control receives a Y1 command (BI-7) from the thermostat the low capacity compressor output (BO2) will be enabled and the ECM blower will operate in medium speed. When the control receives a Y2 command (BI-8) from the thermostat the full capacity compressor output will be enabled and the ECM blower will operate in high speed. During the cooling cycle the reversing valve will be commanded into the “ON” position.
Auxiliary heat output can be controlled over the BAS. Set Point Control Mode In set point control mode the reversing valve output will be disabled. As the temperature drops below the heating set point and begins to operate in the heating proportional band, the low capacity compressor output (BO-2) will be enabled. A PI loop in the programming of the control will determine when the full capacity compressor output (BO-4) is to be enabled. The compressor must be operating in low capacity for a minimum of 30 seconds before the full capacity compressor output can be enabled. During low capacity compressor operation the ECM blower will operate in 37

Inputs and Outputs Configuration
Blower speeds will be selected through the user interface or the facility management system. There will be a total of 12 speeds selectable with only three being selected at any one time. The lowest numbered speed selection set to ON will select the low-speed blower setting, the middle selection set to ON will select the medium-speed blower setting and the highest selection set to ON will select the high-speed blower setting. If all selections are set to OFF the software shall select speed setting 10 for low-speed, 11 for medium-speed, and will select speed setting 12 for high speed. If only one selection is set to ON, that selection will set the low-speed blower setting, the medium-speed setting will be 11, and the high-speed setting will be speed 12. The maximum low-speed setting will be speed 10 and the minimum high-speed setting will be speed 3. In addition there is a low limit setting in the software to prevent the ECM blower speed from being set below acceptable limits for each unit size.
Field Selectable Options Freeze Detection Set Point (BI-5) The freeze detection set point input allows you to adjust the freeze detection set point (AI-5). When the jumper is installed on BI-5 (Wire #24) the freeze detection set point is factory set for 30°F. When the jumper on BI-5 (Wire #24) is removed the freeze detection set point will be 15°F. Accessory Outputs (BO-7 and BO-8) Accessory Output 1 will be energized 90 seconds prior to the compressor output being energized. Accessory Output 2 will be energized with the blower output (BO-1). When the corresponding compressor output is turned off the accessory output will be deactivated immediately. These outputs are selectable for normally open or normally closed operation through the Medium User interface or through the Building Automation System. SINGLE and DUAL STAGE WATER-TO-AIR
ECM Blower air flow “Soft Switch Settings” A set of 12 “soft switches” accessible through the user interface or building automation system are used to select the three blower speed settings for the ECM blower motor. The 12 soft switches work in exactly the same way as the hardware switches used on the Premier control (Refer to Blower Performance Data - ECM Motor for proper settings). No more than three soft switches may be set to the “ON” position. The first “ON” switch (the lowest number switch) determines the “low speed blower” setting. The second determines the “medium speed blower” setting, and the third determines the “high speed blower” setting.
Emergency Heat/Network Enabled Output (BO5) This output is set from the factory to enable/disable emergency heat. If a problem occurs with the unit resulting in the compressor being locked out in heating mode, the control will automatically enable this output to turn on field installed electric heat. This output is interlocked with the blower proving input BI-6 (Blower proving sensors must be field supplied and installed). BI-6 must be connected to PB2 position 3 (see unit schematic) in the field if no blower proving sensor is desired. There is a configurable parameter available through a BAS network that must be enabled if this output is to be commanded over the BAS network.

Initiate a control signal to energize the blower motor. Check blower operation. Initiate a control signal to place the unit in the cooling mode. Cooling setpoint must be set below room temperature. First stage cooling will energize after a time delay. Check for correct rotation of scroll compressors in 3 phase applications Incorrect rotation will cause low refrigerant pressures and possibly unusual noise. Switch any two power leads at the compressor or contactor to reverse rotation. Be sure that the compressor and water control valve or loop pump(s) are activated.
Verify that the water flow rate is correct by measuring the pressure drop through the heat exchanger using the P/T plugs and comparing to unit capacity data in specification catalog. Check the temperature of both the supply and discharge water (Refer to Unit Operating Parameters tables). Check for an air temperature drop of 15°F to 25°F across the air coil, depending on the blower speed and entering water temperature. Decrease the cooling set point several degrees and verify high-speed blower operation (ECM only). Adjust the cooling setpoint above the room temperature and verify that the compressor and water valve or loop pumpsdeactivate. 1Initiate a control signal to place the unit in the heating mode. Heating set point must be set above room temperature. First stage heating will energize after a time delay. Check the temperature of both the supply and discharge water (Refer to Unit Operating Parameters tables). Check for an air temperature rise of 20°F to 35°F across the air coil, depending on the blower speed and entering water temperature. If auxiliary electric heaters are installed, increase the heating setpoint until the electric heat banks are sequenced on. All stages of the auxiliary heater should be sequenced on when the thermostat is in the Emergency Heat mode. Check amperage of each element. Adjust the heating setpoint below room temperature and verify that the compressor and water valve or loop pumps deactivate. During all testing, check for excessive vibration, noise or water leaks. Correct or repair as required. Set system to desired normal operating mode and set temperature to maintain desired comfort level. Instruct the owner/operator in the proper operation of the thermostat and system maintenance.
NOTE: Be certain to fill out and forward all warranty registration papers.

Preventive Maintenance Water Coil Maintenance
Condensate Drain
1.
In areas where airborne bacteria produce a slime in the drain pan, it may be necessary to treat chemically to minimize the problem. The condensate drain can pick up lint and dirt, especially with dirty filters. Inspect twice a year to avoid the possibility of overflow.
2.
Keep all air out of the water. An open loop system should be checked to ensure that the well head is not allowing air to infiltrate the water line. Lines should always be airtight. Keep the system under pressure at all times. It is recommended in open loop systems that the water control valve be placed in the discharge line to prevent loss of pressure during off cycles. Closed loop systems must have positive static pressure.
Blower Motors Blower motors are equipped with sealed ball bearings and require no periodic oiling.
NOTE: On open loop systems, if the installation is in an area with a known high mineral content (125 ppm or greater) in the water, it is best to establish with the owner a periodic maintenance schedule so the coil can be checked regularly. Should periodic coil cleaning be necessary, use standard coil cleaning procedures which are compatible with either the cupronickel or copper water lines. Generally, the more water flowing through the unit the less chance for scaling.
Hot Water Generator Coil See Water Coil Maintenance section.
Air Coil The air coil must be cleaned to obtain maximum performance. Check once a year under normal operating conditions and, if dirty, brush or vacuum (with a brush attachment) clean. Care must be taken not to damage the aluminum fins while cleaning.
Other Maintenance Filters
CAUTION: Fin edges are sharp.
Filters must be clean to obtain maximum performance. They should be inspected monthly under normal operating conditions and be replaced when necessary. Units should never be operated without a filter.
Replacement Procedures Obtaining Parts
In-Warranty Material Return
