Horizontal Installation
Horizontal Unit Location
Units are not designed for outdoor installation. Locate
the unit in an INDOOR area that allows enough space
for service personnel to perform typical maintenance or
repairs without removing unit from the ceiling. Horizontal
units are typically installed above a false ceiling or in a
ceiling plenum. Never install units in areas subject to
freezing or where humidity levels could cause cabinet
condensation (such as unconditioned spaces subject
to 100% outside air). Consideration should be given to
access for easy removal of the lter and access panels.
Provide sufcient room to make water, electrical, and
duct connection(s).
If the unit is located in a conned 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 difcult to remove after the unit is
installed should be removed prior to setting the unit. Refer
to Figure 3 for an illustration of a typical installation. Refer
to unit engineering design guide for dimensional data.
Mounting Horizontal Units
Horizontal units have hanger kits pre-installed from the factory
as shown in Figure 1. Figure 3 shows a typical horizontal unit
installation.
Horizontal heat pumps are typically suspended above a ceiling
or within a soft using eld supplied, threaded rods sized to
support the weight of the unit.
Use four (4) eld supplied threaded rods and factory provided
vibration isolators to suspend the unit. Hang the unit clear of the
oor slab above and support the unit by the mounting bracket
assemblies only. DO NOT attach the unit ush with the oor
slab above.
Pitch the unit toward the drain as shown in Figure 2 to improve
the condensate drainage. On small units (less than 2.5
tons/8.8kW) ensure that unit pitch does not cause condensate
leaks inside the cabinet.
In limited side access installations, pre-removal of the
control box side mounting screws will allow control box
removal for future servicing (HB units only).
Conform to the following guidelines when selecting
unit location:
1. Provide a hinged access door in concealed-spline
or plaster ceilings. Provide removable ceiling
tiles in T-bar or lay-in ceilings. Refer to horizontal
unit dimensions for specic series and model in
unit submittal data. Size the access opening to
accommodate the service technician during the
removal or replacement of the compressor and the
removal or installation of the unit itself.
2.
Provide access to hanger brackets, water valves
and ttings. Provide screwdriver clearance to access
panels, discharge collars and all electrical connections.
3. DO NOT obstruct the space beneath the unit with
piping, electrical cables and other items that prohibit
future removal of components or the unit itself.
4. Use a manual portable jack/lift to lift and support the
weight of the unit during installation and servicing.
The installation of water source heat pump units and all
associated components, parts and accessories which
make up the installation shall be in accordance with
the regulations of ALL authorities having jurisdiction
and MUST conform to all applicable codes. It is the
responsibility of the installing contractor to determine and
comply with ALL applicable codes and regulations.

Field Conversion of Air Discharge
Overview
Horizontal units can be eld converted between side (straight)
and back (end) discharge using the instructions below.
Note: It is not possible to eld convert return air between
left or right return models due to the necessity of
refrigeration copper piping changes.
Preparation
It is best to eld convert the unit on the ground before hanging.
If the unit is already hung it should be taken down for the eld
conversion.
Side to Back Discharge Conversion
1.
Place unit in well lit area. Remove the screws as shown in
Figure 4 to free top panel and discharge panel.
2. Lift out the access panel and set aside. Lift and rotate
the discharge panel to the other position as shown, being
careful with the blower wiring.
3.
Check blower wire routing and connections for tension or
contact with sheet metal edges. Reroute if necessary.
4. Check refrigerant tubing for contact with
other components.
5. Reinstall top panel and screws noting that the location for
some screws will have changed.
6. Manually spin the fan wheel to insure that the wheel is not
rubbing or obstructed.
7. Replace access panels.
Figure 4: Left Return Side to Back
Back to Side Discharge Conversion
If the discharge is changed from back to side, use above
instruction noting that illustrations will be reversed.
Left vs. Right Return
It is not possible to eld convert return air between left or right
return models due to the necessity of refrigeration copper
piping changes. However, the conversion process of side to
back or back to side discharge for either right or left return
conguration is the same. In some cases, it may be possible
to rotate the entire unit 180 degrees if the return air connection
needs to be on the opposite side. Note that rotating the unit will
move the piping to the other end of the unit.

Horizontal Installation
Condensate Piping – Horizontal Units
Pitch the unit toward the drain as shown in Figure 2 to
improve the condensate drainage. On small units (less
than 2.5 tons/8.8 kW), insure that unit pitch does not
cause condensate leaks inside the cabinet.
Install condensate trap at each unit with the top of the trap
positioned below the unit condensate drain connection as
shown in Figure 6.
Each unit must be installed with its own individual trap
and connection to the condensate line (main) or riser.
Provide a means to ush or blow out the condensate line.
DO NOT install units with a common trap and/or vent.
Always vent the condensate line when dirt or air can
collect in the line or a long horizontal drain line is
required. Also vent when large units are working against
higher external static pressure than other units connected
to the same condensate main since this may cause
poor drainage for all units on the line. WHEN A VENT
IS INSTALLED IN THE DRAIN LINE, IT MUST BE
LOCATED AFTER THE TRAP IN THE DIRECTION OF
THE CONDENSATE FLOW.

CAUTION!
CAUTION! Ensure condensate line is pitched toward drain
1/4” per foot [21mm per m] of run.
Duct System Installation
Proper duct sizing and design is critical to the
performance of the unit. The duct system should be
designed to allow adequate and even airow through
the unit during operation. Air ow through the unit MUST
be at or above the minimum stated airow for the unit
to avoid equipment damage. Duct systems should
be designed for quiet operation. Refer to Figure 3 for
horizontal duct system details or gure 8 for vertical duct
system details. A exible connector is recommended
for both discharge and return air duct connections on
metal duct systems to eliminate the transfer of vibration
to the duct system. To maximize sound attenuation of
the unit blower, the supply and return plenums should
include internal berglass duct liner or be constructed
from ductboard for the rst few feet. Application of the
unit to uninsulated ductwork in an unconditioned space
DUCT SYSTEM INSTALLATION
is not recommended, as the unit’s performance will be
adversely affected.
At least one 90° elbow should be included in the supply
duct to reduce air noise. If air noise or excessive air ow
is a problem, the blower speed can be changed. For
airow charts, consult submittal data for the series and
model of the specic unit.
If the unit is connected to existing ductwork, a previous
check should have been made to insure that the
ductwork has the capacity to handle the airow required
for the unit. If ducting is too small, as in the replacement
of a heating only system, larger ductwork should be
installed. All existing ductwork should be checked for
leaks and repaired as necessary.

unit. Refer to Figures 7 and 8 for typical installation
illustrations. Refer to unit submittal data or engineering
design guide for dimensional data.
1. Install the unit on a piece of rubber, neoprene or
other mounting pad material for sound isolation. The
pad should be at least 3/8” [10mm] to 1/2” [13mm] in
thickness. Extend the pad beyond all four edges of
the unit.
2. Provide adequate clearance for lter replacement
and drain pan cleaning. Do not block lter access
with piping, conduit or other materials. Refer to
unit submittal data or engineering design guide for
dimensional data.
3. Provide access for fan and fan motor maintenance
and for servicing the compressor and coils without
removing the unit.
4. Provide an unobstructed path to the unit within the

Sound Attenuation for Vertical Units
Sound attenuation is achieved by enclosing the unit within a
small mechanical room or a closet. Additional measures for
sound control include the following:
1. Mount the unit so that the return air inlet is 90° to the
return air grille. Refer to Figure 9. Install a sound bafe as
illustrated to reduce line-of sight sound transmitted through
return air grilles.
2.
Mount the unit on a rubber or neoprene isolation pad to minimize vibration transmission to the building structure.
Figure 9: Vertical Sound Attenuation
Condensate Piping – Vertical Units
Vertical units utilize a condensate hose inside the cabinet as
a trapping loop; therefore an external trap is not necessary.
Figure 10a shows typical condensate connections. Figure 10b
illustrates the internal trap for a typical vertical heat pump.
Each unit must be installed with its own individual vent (where
necessary) and a means to ush or blow out the condensate
drain line. Do not install units with a common trap and/or vent.

NOTICE! Units with clear plastic drain lines should have
regular maintenance (as required) to avoid buildup of debris,
especially in new construction.
* Some units include a painted drain connection. Using a
threaded pipe or similar device to clear any excess paint
accumulated inside this fitting may ease final drain line installation.

Piping Installation
Installation of Supply and Return Piping
Follow these piping guidelines.
1. Install a drain valve at the base of each supply and
return riser to facilitate system ushing.
2. Install shut-off / balancing valves and unions at each
unit to permit unit removal for servicing.
3. Place strainers at the inlet of each system
circulating pump.
4. Select the proper hose length to allow slack between
connection points. Hoses may vary in length by +2%
to -4% under pressure.
5. Refer to Table 1. Do not exceed the minimum bend
radius for the hose selected. Exceeding the minimum
bend radius may cause the hose to collapse, which
reduces water ow rate. Install an angle adapter to
avoid sharp bends in the hose when the radius falls
below the required minimum.
Insulation is not required on loop water piping except
where the piping runs through unheated areas, outside
the building or when the loop water temperature is
below the minimum expected dew point of the pipe
ambient conditions. Insulation is required if loop water
temperature drops below the dew point (insulation is
required for ground loop applications in most climates).
A backup wrench is required when tightening water
connections on HB series to prevent water line damage.
CAUTION!
CAUTION! Corrosive system water requires corrosion resis-
tant ttings and hoses, and may require water treatment.
CAUTION!
CAUTION! Do not bend or kink supply lines or hoses.
CAUTION!
CAUTION! Piping must comply with all applicable codes.
Table 1: Metal Hose Minimum Bend Radii
Hose Diameter Minimum Bend Radii
1/2" [12.7mm] 2-1/2" [6.4cm]
3/4" [19.1mm] 4" [10.2cm]
1" [25.4mm] 5-1/2" [14cm]
1-1/4" [31.8mm] 6-3/4" [17.1cm]
Pipe joint compound is not necessary when Teon®
thread tape is pre-applied to hose assemblies or when
ared-end connections are used. If pipe joint compound
is preferred, use compound only in small amounts on
the external pipe threads of the tting adapters. Prevent
sealant from reaching the ared surfaces of the joint.
Note: When anti-freeze is used in the loop, insure that it
is compatible with the Teon tape or pipe joint compound
that is applied.
Maximum allowable torque for brass ttings is 30 ft-lbs
[41 N-m]. If a torque wrench is not available, tighten
nger-tight plus one quarter turn. Tighten steel ttings
as necessary.
Optional pressure-rated hose assemblies designed
specically for use with Heat Controller units are available.
Similar hoses can be obtained from alternate suppliers.
Supply and return hoses are tted with swivel-joint ttings
at one end to prevent kinking during installation.
Refer to Figure 11 for an illustration of a typical supply/
return hose kit. Adapters secure hose assemblies to the
unit and risers. Install hose assemblies properly and
check regularly to avoid system failure and reduced
service life.
NOTICE! Do not allow hoses to rest against structural
building components. Compressor vibration may be
transmitted through the hoses to the structure, causing
unnecessary noise complaints.
