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.
Follow all safety codes. Wear safety glasses and work gloves. Use a quenching cloth for brazing
operations and have a fire extinguisher available.
Move units in the normal “up” orientation. 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.

General
Installation
Information
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.

SETTING VERTICAL UNITS
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
Vibration
Absorbing
Mesh
Air
Pad
anchor the unit to the floor (see Figure 1). Bottom
flow units should be mounted level and sealed well
to floor to prevent air leakage.
NOTE:
If access to the left side of the unit will be limited after installation, remove the two mounting
Figure 1 – Vertical Unit 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.
SETTING HORIZONTAL UNITS
CAUTION:
Do not use rods smaller than 3/8” diameter since they may not be strong enough to
support the unit. The rods must be securely anchored to the ceiling.
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 six 3/8” 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 2. 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. The unit should be pitched approximately 1/4” towards the drain in
both directions to facilitate the removal of condensate. (see Figure 5A on page 6). Use only the bolts
provided in the kit. The use of longer bolts could damage internal parts.
Some residential 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 mesh.
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 mesh.

DUCT SYSTEM
CAUTION:
Be sure to remove the shipping material from the blower discharge before connecting
ductwork.
An air outlet collar is provided on vertical top flow units and all horizontal units to facilitate a duct
connection (vertical bottom flow units have no collar). 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" 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 few 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 (see the
Blower Speed and Blower Performance sections on page 19).
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. (See Table
2 on page 21 for water flow and pressure drop information.)
All source water connections are swivel piping fittings that accept a 1" male pipe thread (MPT) (see
Figure 4A). The swivel connector has a rubber gasket seal similar to a rubber hose gasket, which when
mated to the flush end of any 1" 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
CK4S connector kits) 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 (see Figure
4B). Tighten the connectors by hand, then gently snug the fitting with pliers to provide a leak-proof joint.
When connecting to an open loop (groundwater) system, thread any 1" MPT fitting (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.
Never use flexible hoses smaller than 1" inside diameter on the unit. Limit hose length to
10 ft. per connection. Check carefully for water leaks.

WATER QUALITY
The unit may be ordered with either a copper or a cupronickel coaxial heat exchanger. Copper is
adequate for closed loop and open loop groundwater systems which are not high in mineral content. In
conditions anticipating moderate scale formation or in brackish water, a cupronickel heat exchanger is
recommended. 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 setting). (See schematics on
pages 14 and 15.)
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" 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 Figure 5B). If a vent is necessary, an
open stand pipe may be applied to a tee in the field-installed condensate piping.

GROUND SOURCE SYSTEMS
NOTE:
For closed loop systems with antifreeze protection, set SW2-2 to the "LOOP" position.
(See schematics on pages 14 and 15.)
Once piping is completed between the unit, flow center and the ground loop (see Figure 6 on
page 7), final purging and charging of the loop is required. A WaterFurnace 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 checkingthe pressure drop across
the heat exchanger and comparing it to the figures shown in Table 2 on page 21. Usually 2.5 to 3 gpm
of flow per ton of cooling capacity is recommended in earth loop applications. (See Figure 13 on
page 13 for loop pump power wiring details.)
MULTIPLE UNITS ON ONE FLOW CENTER
When two Premier E units are connected to one loop pumping system, pump control is
automatically achieved by connecting the slave terminals on connector P2 in both units with 2-wire
thermostat wire. These terminals are polarity dependant (see Figure 7 on page 7). The loop pump(s)
may be powered from either Premier 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.

Systems
OPEN LOOP SYSTEMS
NOTE:
set SW2-Switch #2 to the “WELL” position,
Typical open loop piping is shown in Figure 8. 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. Insure
proper water flow through the unit by checking pressure drop across the heat exchanger and
comparing it to the figures in Table 2 on page 21. Usually 1.5-2 gpm of flow per ton of cooling
capacity is recommended in open loop applications. In dual capacity units, stage 1 is half of the total
tonnage. Therefore, on a E048, the stage 1 solenoid should flow 3-6 gpm and stage 1 & 2 together
should flow 6-9 gpm.
Discharge water from the unit is not contaminated in any manner and can be disposed of in
various ways, depending on local building codes, i.e. recharge well, storm sewer, drain field, adjacent
stream or pond, etc. Most local codes forbid the use of sanitary sewer for disposal. Consult your
local building and zoning department to assure compliance in your area.

WATER TANK PREPARATION
A family of four should have a water heater with a minimum 50-gallon capacity. For families of
more than four, use an 80-gallon water heater or two 50-gallon water heaters connected in a series as
shown in Figure 12 on page 11. Electric water heaters are recommended.
CAUTION:
1) Turn off the power to the water heater.
2) Attach a water hose to the water tank drain connection and run the other end of the hose to an
open drain or outdoors.
3) Close the cold water inlet valve to the water heater tank.
4) Drain the tank by opening the valve on the bottom of the tank, then open the pressure relief valve
or hot water faucet.
5) Flush the tank by opening the cold water inlet valve to the water heater to free the tank of
sediments. Close when draining water is clear.
6) Disconnect the garden hose and remove the drain valve from the water heater.

WATER TANK REFILL
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 (located in the Premier E
unit) 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.
DESUPERHEATER START UP
CAUTION:
Never operate the DHW circulating pump while dry.
Electrical
Connections
1) Make sure that any valves in the desuperheater water circulating circuit are open.
2) Turn on the Premier E unit to first stage heating.
3) 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.
4) 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.
5) Allow the unit to heat water for 15 to 20 minutes to be sure operation is normal.
6) 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.
DESUPERHEATER NOTE
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.
NOTE:
Do not run DHW 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.
GENERAL
Be sure the available power is the same voltage and phase as that shown on the unit serial plate.
Line and low voltage wiring must be done in accordance with local codes or the National Electric Code,
whichever is applicable.

A set of "dry" contacts has been provided to control accessory devices, such as water solenoid
valves on open loop installations, electronic air cleaners, humidifiers, etc. This relay contact should
be used only with 24 volt signals and not line voltage power. The relay has both normally open
and normally closed contacts and can operate with either the fan or the compressor. Use DIP switch
SW2-3 to cycle the relay with fan or compressor. The relay contacts are available on terminals #2 and
#3 of P3. (See the wiring schematic on pages 14-15 for details).
208 VOLT OPERATION
All Premier E units are factory wired for 230 volt operation. There is a switch located on the control
box, which allows the installer to select 208 volt unit operation. (Refer to Figure 13 on page 13 for
switch location).

Control Operation
NOTE:
DIP switch SW2-#8 is required to be in the OFF position for the Premier E control to
recognize the 24VAC thermostat inputs. SW2-#8 must be ON when using the TA32E12
thermostat. The second stage compressor wire must be installed between the unit and the thermostat
for proper control operation.
HEATING OPERATION
Heat, 1st Stage (Y1)
The fan motor is started on low speed immediately; the first 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 and the hot water pump
is cycled 30 seconds after the “Y1” input.
Heat, 2nd Stage (Y1,Y2)
The compressor is de-energized immediately; the second loop pump is energized 5 seconds after
the “Y2” input; and the hot water pump is cycled 30 seconds after the “Y2” input. The fan changes to
high speed 45 seconds after the “Y2” input and the compressor is energized on high capacity 60
seconds after the “Y2” input.
Heat, 3rd Stage (Y1,Y2,W)
The hot water pump is de-energized which directs all heat to satisfy the thermostat. 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.
16
Page 17
PREMIER E SERIES DUAL CAPACITY INSTALLATION AND MAINTENANCE MANUAL
Emergency Heat (W only)
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 any time 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 first 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 (85% of medium fan
speed if in dehumidification mode) and the hot water pump is cycled 30 seconds after the “Y1” input.
Cool, 2nd Stage (Y1,Y2,O)
The compressor is de-energized immediately, the second loop pump is energized 5 seconds after
the “Y2” input, and the hot water pump is cycled 30 seconds after the “Y2” input. The fan changes to
high speed (85% of high fan speed if in dehumidification mode) 45 seconds after the “Y2” input and
the compressor is energized on high capacity 60 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 pumps, 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, and if the
thermostat calls for heating 2nd or 3rd stage, emergency heat operation will occur.
Lockout modes of any kind can be reset at the thermostat by turning the mode switch “OFF” for
five seconds then back to desired modes, 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.
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 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
The Premier E control board monitors fan RPM to sense if the fan is not operating. This lockout
mode occurs if the fan RPM falls below the low RPM limit (100 RPM) for 30 continuous seconds.

for both sides of coil, a thorough water rinse should follow.
START-UP STEPS:
NOTE:
Complete the Equipment Start-Up/Commissioning Check Sheet (WFS147) during this proce-
dure. Refer to thermostat operating instructions and complete the start-up procedure.
1) Initiate a control signal to energize the blower motor. Check blower operation.
2) Initiate a control signal to place the unit in the cooling mode. Cooling setpoint must be set
below room temperature.
3 First stage cooling will energize after a time delay.
4) Be sure that the compressor and water control valve or loop pumps are activated.
5 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 water pressure drop found on Table 2
on page 21.
6) Check the temperature of both the supply and discharge water. (Refer to Table 1 on page 21.)
7) Check for an air temperature drop of 15 to 25 degrees Fahrenheit 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.
Verify that the compressor switches to high-capacity operation after a one-minute time delay.
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 Table 1 on
page 21.)
13) Check for an air temperature rise of 20 to 35 degrees Fahrenheit across the air coil,
depending on the fan speed and entering water temperature.
14) Increase the heating set point 2-3 degrees above current room temperature and verify that
the compressor switches to high-capacity operation after a one-minute time delay.

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
ppm or greater)
in the water, it is best to establish with the owner a periodic maintenance schedule so
high mineral content (125
the coil can be checked regularly. Should periodic coil cleaning be necessary, use standard coil
cleaning procedures which are compatible with either the cupro-nickel or copper
water lines. Generally, the more water flowing through the unit the less chance for scaling.
OTHER MAINTENANCE
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 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.
Troubleshooting
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.
CAUTION:
NOTE:
To obtain maximum performance, the air coil should be cleaned before start-up. A 10 percent
Fin edges are sharp.
solution of dishwasher detergent and water is recommended for both sides of coil; a thorough water
rinse should follow.
ECM2 Fan Motors
ECM2 Blower Motors are equipped with sealed ball bearings and require no periodic oiling.
Desuperheater Coils
See Water Coil Maintenance section above.
CONTROLS
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).
22
Page 23
PREMIER E SERIES DUAL CAPACITY INSTALLATION AND MAINTENANCE MANUAL
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.
Refer to the wiring schematic on pages 14-15 for additional information.
NOTE:
REFRIGERANT SYSTEM
NOTE:
Verify that air and water flow rates are at proper levels before servicing the
refrigerant circuit.
To maintain sealed circuit integrity, do not install service gauges unless unit operation appears
abnormal (refer to the unit operating pressures and temperatures table below). If superheat and
subcooling are outside recommended ranges, an adjustment to the refrigerant charge may
be necessary.
