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 compo-
nents. 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 clean-
ing 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 extin-
guisher available.
Moving and Storage
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.
Safety Considerations
General Installation Information
Vertical Unit Mounting
2 in. PEX Foam
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
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.
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 figure below).

Installing Horizontal Units
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.
NOTE: Horizontal units are normally suspended from a ceiling by
four (009-060 models) or five (070-072 models) 3/8 in. 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 Hanger Bracket Dimensions
table. 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, install hanger brackets
as illustrated in the Hanger Bracket Locations section. 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.
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.
CAUTION: Do not use rods smaller than 3/8 in.
diameter since they may not be strong enough to
support the unit. The rods must be securely anchored
to the ceiling.

An air outlet collar is provided on vertical top flow units and all
horizontal units to facilitate a duct connection. Aflexible 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.
Duct System
Water Piping
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 ductboarad 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.
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 at
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 commercial units are fittings that
accept a male pipe thread (MPT). Insert the connectors by hand,
then tighten the fitting with a wrench to provide a leakproof joint.
When connecting to an open loop (groundwater) system, thread
any copper MPT fitting into the connector and tighten in the same
manner as described above.

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 PVC stub or stainless steel tube is provided
for condensate drain piping connection. An external trap is required
(see below). If a vent is necessary, an open stand pipe may be
applied to a tee in the field-installed condensate piping.

In ground water 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 ground
water 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. Hot water
generator 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. Failure
to adhere to the guidelines in the water quality table could result in
loss of warranty.
Units with cupronickel heat exchangers are recommended for open
loop applications due to the increased resistance to build-up and
corrosion, along with reduced wear caused by acid cleaning.
System Cleaning and Flushing
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
(This will prevent the introduction of dirt into the unit, see Flushing
with Water Shutoff Valve Equipped Systems illustration). The
system should be filled at the water make-up 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 circulates 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 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

Typical open loop piping is shown below. 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 unit capacity data tables in the specification catalog.
1.5-2 gpm of flow per ton of cooling capacity is recommended in
open loop applications. Due to only minor differences in flow rate
from low to high, only one solenoid valve should be used. The valve
should be sized for full flow.
Discharge water from the unit is not contaminated in any manner and
can be disposed of in various ways, depending on local 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 departments to assure compliance in
your area.

adjust the make-up 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, until 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 application, 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.
Ground Source Loop System Checkout
Once piping is completed between the unit pumping system and
ground loop, final purging and charging of the loop is needed. A
high pressure pump 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 may decrease soon after initial
installation, due to pipe expansion and loop temperature change.
Running the unit for at least 30 minutes after the system has been
completely purged of air will allow for the “break-in” period. It may
be necessary to adjust static loop pressure (by adding water) after
the unit has run for the first time. Loop static pressure will also
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 charging the system initially.
Ensure the pump provides adequate flow through the unit by
checking pressure drop across the heat exchanger.
Usually 2.25-3.0 gpm of flow per ton of cooling capacity is
recommended in earth loop applications.

The heat reclaiming hot water generator coil is of vented double-
wall copper construction and is suitable for potable water.
To maximize the benefits of the hot water generator a minimum
50-gallon water heater is recommended. For higher demand
applications, use an 80-gallon water heater or two 50-gallon
water heaters connected in a series as shown below. Electric
water heaters are recommended. Make sure all local electrical
and plumbing codes are met for installing a hot water generator. A

Water Tank Preparation
To install a unit with a hot water generator, follow these
installation guidelines.
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.
7. Refer to Plumbing Installation and Hot Water Generator Startup.
Plumbing Installation
1. Inspect the dip tube in the water heater cold inlet for a check
valve. If a check valve is present it must be removed or
damage to the hot water generator circulator will occur.
2. Remove drain valve and fitting.
3. Thread the 3/4-inch NPT x 3-1/2-inch brass nipple into the
water heater drain port.
4. Attach the center port of the 3/4-inch FPT tee to the opposite
end of the brass nipple.
5. Attach the 1/2-inch copper to 3/4-inch NPT adaptor to the side
of the tee closest to the unit.
6. Install the drain valve on the tee opposite the adaptor.
7. Run interconnecting tubing from the tee to HWG water out.
8. Cut the cold water “IN” line going to the water heater.
9. Insert the reducing solder tee in line with cold water “IN” line
as shown.
10.Run interconnecting copper tubing between the unit DHW
water “IN” and the tee (1/2-inch nominal). The recommended
maximum distance is 50 feet.
11.
To prevent air entrapment in the system, install a vent coupling
at the highest point of the interconnecting lines.
12.Insulate all exposed surfaces of both connecting water lines
with 3/8-inch wall closed cell insulation.
NOTE: All plumbing and piping connections must comply with local
plumbing codes.

CAUTION: Never operate the HWG circulating
pump while dry. If the unit is placed in operation
before the hot water generator piping is connected,
be sure that the pump wires are disconnected from
the contactor.
Hot Water Generator Connections cont.
Hot Water Generator Startup
1. Make sure the power is off to the heat pump. Connect the wire
from the hot water generator pump to T1 on the contactor.
2. Close the drain valve to the water heater.
3. Open the cold water supply to the tank.
4. Open a hot water faucet in the building to bleed air from the
system. Close when full.
5. Open the pressure relief valve to bleed any remaining air from
the tank, then close.
6. If so equipped, turn the venting (burping) screw in the center of
the pump two (2) turns open (water will drip out), wait until all air is
purged from the pump, then tighten the plug. Use vent couplings to
bleed air from the lines.
7. Carefully inspect all plumbing for water leaks and correct
as required.
8. 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.
9. After the thermostat(s) is adjusted, replace the access cover
and restore electrical supply to the water heater.
10. Make sure that any valves in the hot water generator circuit
are open.
11. Turn on the unit to heating.
12. The HWG pump should be running. When the pump is first
started, turn the venting (burping) screw (if equipped) in the
center of the pump two (2) turns open 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.
13. The temperature difference between the water entering
and leaving the hot water generator should be 5°F to 15°F.
The water flow should be approximately 0.4 gpm per ton of
nominal cooling.
14. Allow the unit to heat water for 15 to 20 minutes to be sure
operation is normal.
