PREMIER INSTALLATION MANUAL
General Installation Information
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.
Safety Considerations
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.
Follow all safety codes. Wear safety glasses and work gloves. Use a quenching cloth for brazing operations and have a
fire extinguisher available.
Moving and Storage
Move units in the normal “up” orientation as indicated by the arrows on each carton. Horizontal units may be moved and
stored per the information on the carton. 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 cartons 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. Units are to be stored in clean, dry location to prevent damage.
Unit Location
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.
Installing Vertical Units
Vertical units are available in left or right air return configurations. 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). If access to the left side of the unit will be
limited after installation, remove the two mounting screws on the left side of the
control box before setting the unit (leave the two front mounting screws intact).
This will allow the control box to be removed with only the two front mounting
screws for future service.

PREMIER INSTALLATION MANUAL
Installing Horizontal Units
Horizontal units are available with side or end discharge and may be field converted from one to the other by replacing the discharge panel with a new panel which must be ordered separately. Horizontal units are normally suspended from
a ceiling by four or six 3/8-inch diameter threaded rods. The rods are usually attached to the unit by hanger bracket kits
furnished with each unit.
Lay out the threaded rods per the dimensions in Figure 3. Assemble the hangers to the unit as shown. Securely tighten
the brackets to the unit using the weld nuts located 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

PREMIER INSTALLATION MANUAL
Duct System
An air outlet collar is provided on vertical top flow units and all horizontal units to facilitate a duct connection. A flexible
connector is recommended for discharge and return air duct connections on metal duct systems. Uninsulated duct should
be insulated with a minimum of 1-inch duct insulation. Application of the unit to uninsulated ductwork in an unconditioned
space is not recommended as the unit’s performance will be adversely affected.
If the unit is connected to existing ductwork, check the duct system to ensure that it has the capacity to accommodate
the air required for the unit application. If the duct is too small, as in the replacement of heating only systems, larger ductwork should be installed. All existing ductwork should be checked for leaks and repaired if necessary.
The duct system should be sized to handle the design airflow quietly and efficiently. To maximize sound attenuation of
the unit blower, the supply and return plenums should include an internal duct liner of fiberglass or constructed of ductboard
for the first 10 feet. On systems employing a sheet metal duct system, canvas connectors should be used between the unit
and the ductwork. If air noise or excessive airflow is a problem, the blower speed can be changed (refer to pages 16-17).
CAUTION: Be sure to remove the shipping material from the blower discharge before
connecting ductwork.
Water Piping
The proper water flow must be provided to each unit whenever the unit operates. To assure proper flow, use pressure/
temperature ports to determine the flow rate. These ports should be located adjacent to the supply and return water connections on the unit. The proper flow rate cannot be accurately set without measuring the water pressure drop through the
refrigerant-to-water heat exchanger.
All source water connections on residential units are swivel fittings that accept a 1-inch male pipe thread (MPT). The
swivel connector has a rubber gasket seal similar to a rubber hose gasket, which when mated to the flush end of any 1-inch
threaded pipe provides a leak-free seal without the need for thread sealing tape or compound. Check to ensure that the rubber seal is in the swivel connector prior to attempting any connection. The rubber seals are shipped attached to the waterline. To make the connection to a ground loop system, mate the brass connector (supplied in CK4L and CK3L connector kit)
against the rubber gasket in the swivel connector and thread the female locking ring onto the pipe threads, while maintaining the brass connector in the desired direction. Tighten the connectors by hand, then gently snug the fitting with pliers to
provide a leak-proof joint. When connecting to an open loop (ground water) system, thread any 1-inch MPT fitting (SCH80
PVC or copper) into the swivel connector and tighten in the same manner as noted above. The open and closed loop piping
system should include pressure/temperature taps for serviceability.
All source water connections on commercial units are standard female pipe thread.
Never use flexible hoses smaller than 1-inch inside diameter on the unit. Limit hose length to 10 feet per connection.
Check carefully for water leaks.
Water Quality
In groundwater situations where scaling could be heavy or where biological growth such as iron bacteria will be present, a closed loop system is recommended. The heat exchanger coils in groundwater systems may, over a period of time,
lose heat exchange capabilities due to a buildup of mineral deposits inside. These can be cleaned, but only by a qualified
service mechanic, as special solutions and pumping equipment are required. Desuperheater coils can likewise become
scaled and possibly plugged. In areas with extremely hard water, the owner should be informed that the heat exchanger
may require occasional flushing.
Freeze Protection
Set the freeze protection switch SW2-2 on the printed circuit board for applications using a closed loop antifreeze solution to “LOOP”. On applications using an open loop/groundwater system (or closed loop no antifreeze), set this dip switch to
“WELL”, the factory default setting. (Refer to the Dip Switch Field Selection table on page 20.)
PREMIER INSTALLATION MANUAL
Condensate Drain
On vertical units, the internal condensate drain assembly consists of a drain tube which is connected to the drain pan, a
3/4-inch PVC female adapter and a flexible connecting hose. The female adapter may exit either the front or the side of the
cabinet. The adapter should be glued to the field-installed PVC condensate piping. On vertical units, a condensate hose is
inside all cabinets as a trapping loop; therefore, an external trap is not necessary.
On horizontal units, a copper stub is provided for condensate drain piping connection. An external trap is required (see
Figures 4 and 5 below). If a vent is necessary, an open stand pipe may be applied to a tee in the field-installed condensate
piping.

PREMIER INSTALLATION MANUAL
Closed Loop Ground Source Systems
Note: For closed loop systems with antifreeze protection, set SW2-2 to the “loop” position (see table on page 32).
Once piping is completed between the unit, flow center and the ground loop (see figure below), final purging and charging of the loop is required. A flush cart (or a 1.5 HP pump minimum) is needed to achieve adequate flow velocity in the loop
to purge air and dirt particles from the loop itself. Antifreeze solution is used in most areas to prevent freezing. Flush the
system adequately to remove as much air as possible then pressurize the loop to a static pressure of 40-50 PSI (summer)
or 50-75 PSI (winter). This is normally adequate for good system operation. Loop static pressure will fluctuate with the seasons. Pressures will be higher in the winter months than during the cooling season. This fluctuation is normal and should be
considered when initially charging the system.
After pressurization, be sure to remove the plug in the end of the loop pump motor(s), if applicable, to allow trapped air to
be discharged and to ensure that the motor housing has been flooded. Ensure that the loop flow center provides adequate
flow through the unit by checking the pressure drop across the heat exchanger and comparing it to the unit capacity data
in the specification catalog. Usually 2.5 to 3 GPM of flow per ton of cooling capacity is recommended in earth loop applications. (See wiring diagram attached to the inside of the unit for pump wiring details.)

Multiple Units on One Flow Center
When two units are connected to one loop pumping system, pump control is automatically achieved by
connecting the SL terminals on connector P2 in both
units with 2-wire thermostat wire. These terminals are
polarity dependant. The loop pump(s) may be powered
from either unit, whichever is more convenient. If either
unit calls, the loop pump(s) will automatically start. The
use of two units on one flow center is generally limited to
a total of 20 GPM capacity.

Open Loop Ground Water Systems
Always maintain water pressure in the heat exchanger by placing water control valves at the outlet of the unit to prevent
mineral precipitation. Use a closed, bladder-type expansion tank to minimize mineral formation due to air exposure. Ensure
proper water flow through the unit by checking pressure drop across the heat exchanger and comparing it to the figures in
Capacity Tables in the Specification Catalog. Normally, about 2 GPM flow rate per ton of cooling capacity (1.5 GPM per ton
minimum at 50°F) is needed in open loop systems.
Note: For open loop/ground water systems or systems that do not contain an antifreeze solution, set SW2-Switch #2 to the “WELL” position.

Discharge water from the unit is not contaminated in any
manner and can be disposed of in various ways, depending on
local building codes (e.g. recharge well, storm sewer, drain field,
adjacent stream or pond, etc.). Most local codes forbid using
the sanitary sewer for disposal. Consult your local building and
zoning department to assure compliance in your area.
The water control solenoid is wired between the common pin
#2 connector P1 and pin #3 connector P3, and a jumper wire is
connected between R and pin #1 connector P3 (refer to Figure
9). Notice that DIP switch 2-3, located on the PCB, must be
switched to the “Comp” position so the valve will operate with the
compressor.

Boiler/Cooling Tower Closed Loop Systems
Boiler/Cooling Tower
The water loop is usually maintained between 60°F and 90°F. Premier units allow 25°F to 110°F EWT for proper heating and cooling operation.
To reject excess heat from the water loop, the use of a closed circuit evaporative cooler or an open type cooling tower
with a secondary heat exchanger between the tower and the water loop is recommended. If an open type cooling tower is
used without a secondary heat, continuous chemical treatment and filtering of the water must be performed to ensure the
water is free from damaging materials.
Water Piping Connections
Units should not be connected to the supply and return piping until the water system has been cleaned and flushed
completely. Supply and return water connections are standard female pipe thread on commercial units (1-inch swivel on
residential units). Never use flexible hoses with an inside pipe diameter that is smaller than the water connections on the
unit and limit the hose length to 10 feet or less per connection. High-pressure flexible hoses provide sound attenuation for
both normal unit operating noise and hydraulic pumping noise. Hard piping can also be brought directly to the unit although
it is not recommended since no vibration or noise attenuation can be accomplished.

PREMIER INSTALLATION MANUAL
System Cleaning and Flushing
Prior to start up of any heat pump, the water circulating system must be cleaned and flushed of all dirt and debris. If
the system is equipped with water shutoff valves, the supply and return runouts must be connected together at each unit
location to prevent the introduction of dirt into the unit, (see Figure 10). The system should be filled at the water makeup
connection with all air vents open. After filling, vents should be closed.
The contractor should start the main circulator with the pressure reducing valve makeup open. Vents should be checked
in sequence to bleed off any trapped air and to verify circulation through all components of the system.
As water cirulates through the system, the contractor should check and repair any leaks found in the piping system.
Drain(s) at the lowest point(s) in the system should be opened for the initial flush and blowdown, making sure water fill
valves are set at the same rate. Check the pressure gauge at the pump suction and manually adjust the makeup water
valve to hold the same positive pressure both before and after opening the drain valves. Flushing should continue for at
least two hours, or longer if required, unil drain water is clean and clear.
The supplemental heater and/or circulator pump, if used, should be shut off. All drains and vents should be opened to
completely drain the system. Short circuited supply and return runouts should now be connected to the unit supply and
return connections.
Refill the system with clean water. Test the system water for acidity and treat as required to leave the water slightly
alkaline (pH 7.5 to 8.5). The specified percentage of antifreeze may also be added at this time. Use commercial grade
antifreeze designed for HVAC systems only. Environol™ brand antifreeze is recommended.
Once the system has been filled with clean water and antifreeze (if used), precautions should be taken to protect the
system from dirty water conditions. Dirty water will result in system-wide degradation of performance, and solids may clog
valves, strainers, flow regulators, etc. Additionally, the heat exchanger may become clogged which reduces compressor
service life and can cause premature unit failure. In boiler/tower applications, set the loop control panel set points to desired
temperatures. Supply power to all motors and start the circulating pumps. After full flow has been established through all
components including the heat rejector (regardless of season), air vented and loop temperatures stabilized, each of the
units will be ready for check, test and start up and for air and water balancing.
Note: For closed loop systems with antifreeze protection, set SW2-2 to the “LOOP” position.

10. To prevent air entrapment in the system, install a vent coupling at the highest point of the interconnecting lines.
11. Insulate all exposed surfaces of both connection water lines with 3/8-inch wall closed cell insulation.
Note: All plumbing and piping connections must comply with local plumbing codes.
Desuperheater Startup
1. Close the drain valve to the water heater.
2. Open the cold water supply to the tank.
3. Open the hot water faucet in the house to bleed air from the system. Close when full.
4. Depress the handle on the pressure relief valve to bleed any remaining air from the tank then close.
5. If so equipped, unscrew the indicator plug on the motor end of the pump until all air is purged from the pump, then tighten the plug. Use vent couplings to bleed air from the lines.
6. Carefully inspect all plumbing for water leaks and correct as required.
7. Before restoring electrical supply to the water heater, adjust the temperature setting on the tank.
• On tanks with both upper and lower elements, the lower element should be turned down to the lowest setting,
approximately 100°F. The upper element should be adjusted to 120°F to 130°F. Depending upon the specific needs of the customer, you may want to adjust the upper element differently.
• On tanks with a single element, lower the thermostat setting to 120°F.
8. After thermostat(s) is adjusted, replace the access cover and restore electrical supply to the water heater.
9. Make sure that any valves in the desuperheater water circulating circuit are open.
10. Turn on the Premier unit to first stage heating.
11. The DHW pump should be running. Be sure the disable switch for the DHW pump (SW4) is ON. The DHW OFF LED on the unit should not be illuminated.
12. The temperature difference between the water entering and leaving the desuperheater should be 5°F to 15°F. The
water flow should be approximately 0.4 GPM per ton of nominal cooling.
13. Allow the unit to heat water for 15 to 20 minutes to be sure operation is normal.
14. When the pump is first started, open the inspection port (if equipped) until water dribbles out, then replace. Allow the pump to run for at least five minutes to ensure that water has filled the circulator properly.
CAUTION: Never operate the DHW circulating pump while dry. If the unit is placed in operation before the desuperheater piping is connected, be sure that the pump switch is set to the OFF position.
Desuperheater Notes: When servicing a unit’s refrigeration circuit, it is always good practice to disable the desuperheater
pump. This can be accomplished by using the DHW pump disable switch located on the front of the unit cabinet near
the LED annunciator panel. The red DHW OFF LED will illuminate, indicating the DHW pump is disabled.

PREMIER INSTALLATION MANUAL
Standard Microprocessor Control Operation
The Premier control system is a microprocessor-based printed circuit board conveniently located in the unit control box
for easy accessibility. The microprocessor provides control of the entire unit as well as outputs for status modes, faults, and
diagnostics. Low voltage terminal strips provide all necessary terminals for field connections. LEDs are located on the front
of the unit for quick inspection without removing any access panels. The control offers optimal space conditioning. The
board accepts traditional 24VAC thermostat inputs.
Startup
The unit will not operate until all the inputs and safety controls are checked for normal conditions. At first power-up, a
four-minute delay is employed before the compressor is energized.
Component Sequencing Delays
Components are sequenced and delayed for optimum space conditioning performance.
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 accessory relay is factory set to control the
optional electronic air-cleaner.
Short Cycle Protection
The control employs a minimum “off” time of four minutes and a minimum “on” time of two minutes to provide for short
cycle protection of the compressor.
Loop Pump SL Signals
A signal between multiple Premier control boards at the SL inputs and outputs (SL1-In and Out) will provide for remote
control of the loop pump on any unit.
Condensate Overflow Protection
The Premier 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), the condensate overflow
lockout LED begins flashing, and an output signal (LO) is made available for conneciton to a “fault” LED at the thermostat.
Shutdown Input
A simple grounded signal to the “shutdown” input on the control board puts the unit into shutdown mode. Compressor,
hot water pump and fan operaiotn are suspended
Safety Controls
The Premier 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 protection. Upon a continuous 30-second measurement of the fault (immediate for high pressure), compressor operation is suspended (see fault retry), the appropriate lockout
LED begins flashing, and an output signal (LO) is made available for connection to a “fault” LED at the thermostat.
Testing
The Premier control allows service personnel to shorten most timing delays for faster diagnostics (see field selection DIP
switch #1).
30
PREMIER INSTALLATION MANUAL
Standard Microprocessor Control Operation
Fault Retry
All faults (except for low RPM fault with the ECM2 fan motor) are retried twice before finally locking the unit out. The
“fault retry” feature is designed to prevent nuisance calls.
Diagnostics
The Premier control board allows all inputs and outputs to be displayed on the LEDs for fast and simple control board
diagnosis (see field selection DIP switches #6 and #7).
Resistance Heat Control
For units equipped with internal electric heaters, 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.
Fan Speed Control
A DIP switch on the Premier control allows field selection of low and medium fan speeds for cooling in the dehumidification mode or medium and high fan speeds for cooling in the normal mode (ECM2 version only).
Hot Water High Limit
This mode occurs when the hot water thermistor temperature is at or above 130°F for 30 continuous seconds. The DHW
limit status LED on the unit illuminates, and the hot water pump de-energizes. Hot water pump operations resume on the
next compressor cycle or after 30 minutes of continuous compressor operation during the current thermostat demand cycle.
Hot Water Pump Switch
When the pump switch is engaged, hot water pump operation is disabled, and the pump status LED on the unit illuminates.
ECM2 Airflow Selection DIP Switches (SW1)
A 12-position DIP switch package on the Premier control allows the airflow levels to be set for low, medium and high
speed when using the ECM2 blower motor (refer to the Blower table on page 28).
Only three of the DIP switches can be in the “on” position. The first “on” switch (the lowest position number) determines
the “low speed fan” setting. The second “on” switch determines the “medium speed fan” setting, and the third “on” switch
determines the “high speed fan” setting.

6. Check the temperature of both the supply and discharge water. (Refer to the table on page 37.)
7. Check for an air temperature drop of 15°F to 20°F across the air coil, depending on the fan speed and entering water
temperature.
8. Decrease the cooling set point several degrees and verify high-speed blower operation.
9. Adjust the cooling setpoint above the room temperature and verify that the compressor and water valve or loop pumps
deactivate.
10. Initiate a control signal to place the unit in the heating mode. Heating setpoint must be set above room temperature.
11. First stage heating will energize after a time delay.
12. Check the temperature of both the supply and discharge water. (Refer to the table on page 37.)
13. Check for an air temperature rise of 20°F to 35°F across the air coil, depending on the fan speed and entering water
temperature.
15. If auxiliary electric heaters are installed, increase the heating setpoint until the electric heat banks are sequenced on when the thermostat is in the Emergency Heat mode. Check amperage of each element.
16. Adjust the heating setpoint below room temperature and verify that the compressor and water valve or loop pumps
deactivate.
17. During all testing, check for excessive vibration, noise or water leaks. Correct or repair as required.
18. Set system to desired normal operating mode and set temperature to maintain desired comfort level.
19. Instruct the owner/operator in the proper operation of the thermostat and system maintenance.

PREMIER INSTALLATION MANUAL
Description of Unit Operation
Note: Fan speed operation below applies only to units equiped with ECM blower motors.
Heating Operation
Heat, 1st Stage (Y1)
The fan motor is started on low speed immediately, 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 fan is switched to medium
speed 15 seconds after “Y1” input. The hot water pump is cycled 30 seconds after the “Y1” input.
Heat, 2nd Stage (Y1, Y2)
The hot water pump is de-energized, which directs all heat to satisfying the thermostat, and the fan changes to high
speed 15 seconds after the “Y2”input.
Heat, 3rd Stage (Y1, Y2, W)
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.
Emergency Heat
The fan 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.
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.
Cool, 1st Stage (Y1,O)
The fan motor is started on low speed immediately, the loop pump is energized 5 seconds after the “Y1” input is
received, and the compressor is energized 10 seconds after the “Y1” input. In the ECM2 version, the fan is switched to medium speed 15 seconds after “Y1” input (remains in low speed if in dehumidification mode). The hot water pump is cycled
30 seconds after the “Y1” input.
Cool, 2nd Stage (Y1, Y2, O)
The fan changes to high speed (85% of high speed if in dehumidification mode) 15 seconds after the “Y2” input.
Fan (G only)
The fan starts on low speed. Regardless of fan input “G” from thermostat, the fan will remain on low speed for 30
seconds at the end of each heating, cooling or emergency heat cycle.
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 ECM2 low RPM fault, the fan will
continue to run on low speed. If the thermostat calls for heating, emergency heat operation will occur.
Lockout modes of any kind can be reset at the thermostat after a 5-second waitinng perioud, which restores normal
operation but keeeps the unit lockout LED illuminated. Interruption of power to the unit will reset a lockout without a waiting
period and clear all lockout LEDs.
High Pressure
This lockout mode occurs when the normally closed safety switch is opened momentarily.
Low Pressure
This lockout mode occurs when the normally closed low pressure switch is opened for 30 continuous seconds.
Freeze Protection (Water Flow)
This lockout mode occurs when the freeze thermistor temperature is at or below the selected freeze protection point
(well 30°F or loop 15°F) for 30 continuous seconds.
Condensate Overflow
This lockout mode occurs when the condensate overflow level has been reached for 30 continuous seconds.
Fan RPM
When equipped with an ECM2 fan motor, the Premier control board monitors fan RPM to sense operation. This
lockout mode occurs if the fan RPM falls below the low RPM limit (100 RPM) for 30 continuous seconds.

Troubleshooting
To check the unit control board for proper operation:
1. Disconnect thermostat wires at the control board.
2. Jumper the desired test input (Y1, Y2, W, O, or G) to the R terminal with the SW2-8 in the “OFF” position to simulate a
thermostat signal.
3. If control functions properly:
- Check for thermostat and field control wiring (use the diagnostic inputs mode).
4. If control responds improperly:
- Ensure that component being controlled is functioning (Compressor, Blower, Reversing Valve, etc.)
- Ensure that wiring from control to the component is functioning (use the diagnostic outputs mode).
- If steps above check properly, replace unit control.
Note: Verify that air and water flow rates are at proper levels before servicing the refrigerant circuit.

PREMIER INSTALLATION MANUAL
Preventive Maintenance
Water Coil Maintenance
1. 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.
2. 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.
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.
Other Maintenance
Air Coil
To obtain maximum performance, the air coil should be cleaned before startup. A 10% solution of dishwasher detergent
and water is recommended for both sides of coil; a thorough water rinse should follow.
CAUTION: Fin edges are sharp.
Fan Motors (ECM & PSC)
Blower Motors are equipped with sealed ball bearings and require no periodic oiling.
Desuperheater Coils
See Water Coil Maintenance section.
Filters
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.
Condensate Drain
In areas where airborne bacteria produce a sludge 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.
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 clean. Care must be taken not to damage the aluminum fins while cleaning.
Replacement Procedures
Obtaining Parts
When ordering service or replacement parts, refer to the model number and serial number of the unit as stamped on the
serial plate attached to the unit. If replacement parts are required, mention the date of installation of the unit and the date of
failure, along with an explanation of the malfunctions and a description of the replacement parts required.
In-warranty Material Return
Material may not be returned except by permission of authorized warranty personnel. Contact your local distributor for
warranty return authorization and assistance.
