NOTICE! Failure to remove shipping brackets from
spring-mounted compressors will cause excessive
noise, and could cause component failure due to
added vibration.
CAUTION! All three phase scroll compressors must have
direction of rotation verifi ed at start-up. Verifi cation is
achieved by checking compressor Amp draw. Amp draw
will be substantially lower compared to nameplate values.
Additionally, reverse rotation results in an elevated sound
level compared to correct rotation. Reverse rotation will
result in compressor internal overload trip within several
minutes. Verify compressor type before proceeding.
CAUTION! DO NOT store or install units in corrosive
environments or in locations subject to temperature or
humidity extremes (e.g., attics, garages, rooftops, etc.).
Corrosive conditions and high temperature or humidity can
signifi cantly reduce performance, reliability, and service
life. Always move and store units in an upright position.
Tilting units on their sides may cause equipment damage.
CAUTION!

CAUTION! CUT HAZARD - Failure to follow this caution
may result in personal injury. Sheet metal parts may have
sharp edges or burrs. Use care and wear appropriate
protective clothing, safety glasses and gloves when
handling parts and servicing heat pumps.
Pre-Installation
Installation, Operation, and Maintenance instructions
are provided with each unit. Horizontal equipment
is designed for installation above false ceiling or in a
ceiling plenum. Other unit confi gurations are typically
installed in a mechanical room. The installation site
chosen should include adequate service clearance
around the unit. Before unit start-up, read all manuals
and become familiar with the unit and its operation.
Thoroughly check the system before operation.
Prepare units for installation as follows:
1. Compare the electrical data on the unit
nameplate with ordering and shipping
information to verify that the correct unit has been
shipped.
2. Keep the cabinet covered with the original
packaging until installation is complete and all
plastering, painting, etc. is fi nished.
3. Verify refrigerant tubing is free of kinks or dents
and that it does not touch other unit components.
4. Inspect all electrical connections. Connections
must be clean and tight at the terminals.
5. Remove any blower support packaging (water-toair units only).
6. Loosen compressor bolts on units equipped with
compressor spring vibration isolation until the
compressor rides freely on the springs. Remove
shipping restraints.
7. Some airfl ow patterns are fi eld convertible
(horizontal units only). Locate the airfl ow
conversion section of this IOM.
8. Locate and verify any hot water generator (HWG),
hanger, or other accessory kit located in the
compressor section or blower section.

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 fi lter
and access panels. Provide suffi cient room to make
water, electrical, and duct connection(s).
If the unit is located in a confi ned 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 diffi cult 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 submittal data or
engineering design guide for dimensional data.
In limited side access installations, pre-removal of the
control box side mounting screws will allow control box
removal for future servicing.
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 specifi c series and model
in unit submittal data. Size the access opening
to accommodate the service technician during
the removal or replacement of the compressor,
control, or blower assembly. Provide access to
hanger brackets, water valves and fi ttings. Provide
screwdriver clearance to access panels, discharge
collars and all electrical connections.
2. 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.
3. 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.
Mounting Horizontal Units
Horizontal units have 4 hanger brackets partially
attached at the factory, one at each corner. Enclosed
within the unit there is a hanger kit hardware bag
containing vibration isolation grommets, washers,
screws and a hanger installation instruction page. One
additional screw from the hardware bag must be added
to each hanger bracket before unit installation.Tighten
each screw to 75 in-lbs (8.5 Nm). See Figure 1. Refer
to the hanger installation instruction page contained
in the hardware bag for details of fi nal hanger bracket
attachment and unit suspension. See Figure 1a.
Use four (4) fi eld supplied threaded rods and factory
provided vibration isolators to suspend the unit. Safely
lift the unit into position supporting the bottom of the
unit. Ensure the top of the unit is not in contact with
any external objects. Connect the top end of the 4
all-thread rods, slide rods through the brackets and
grommet then assemble washers and double nuts at
each rod. Ensure that the unit is approximately level
and that the threaded rod extends past the nuts.
Pitch the unit toward the drain as shown in Figure 2
to improve the condensate drainage. On small units
(less than 8.8 kW) ensure that unit pitch does not cause
condensate leaks inside the cabinet.

Air Coil - To obtain maximum performance, the air coil
should be cleaned before start-up. A 10% solution of
dishwasher detergent and water is recommended for
both sides of the coil. A thorough water rinse should
follow. UV based anti-bacterial systems may damage
coated air coils.
Notice! Installation Note - Ducted Return: Many
horizontal WSHPs are installed in a return air ceiling
plenum application (above ceiling). Vertical WSHPs
are commonly installed in a mechanical room with free
return (e.g. louvered door). Therefore, fi lter rails are the
industry standard and are included on ClimateMaster
commercial heat pumps for the purposes of holding
the fi lter only. For ducted return applications, the fi lter
rail must be removed and replaced with a duct fl ange
or fi lter frame. Canvas or fl exible connectors should
also be used to minimize vibration between the unit
and ductwork.

Field Conversion of Air Discharge
Overview -
Horizontal units can be fi eld converted
between straight (side) and back (end) discharge using
the instructions below.
Note: It is not possible to fi eld convert return air
between left or right return models due to the
necessity of refrigeration copper piping changes.
Preparation - Field conversion must be completed
on the ground. If the unit is already hung it should be
taken down for the fi eld conversion. Place in a well-
lighted area. Conversion should only be attempted by
a qualifi ed service technician.
Side to Back Discharge Conversion
1. Remove back panel and side access panel
2. Loosen 2 motor slide nuts, raise motor slide
assembly and remove belt and motor sheave.
3. Remove blower sheave. Remove motor bolts and
carefully remove motor.
4. Remove 2 motor clips and reattach to opposite
side.
5. Unbolt (3 per side) complete housing assembly.
6. Rotate complete assembly into new position.
Locate over mounting holes in base, reattach using
3 bolts per side.
7. Mount motor, motor sheave, blower sheave and
belt. Make sure wires are not pinched and not over
sharp edges. Adjust motor downward to tighten
belt. Raise or lower motor slide assembly with
adjusting bolt and retighten 2 slide nuts. Check
for correct tension (See Tensioning V-Belt Drives
page). Rewire motor (at contactor) for correct
rotation. Spin blower wheel to ensure wheel is not
obstructed.
8. Replace 2 panels.
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 fi 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
confi guration 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 - A condensate
drain line must be installed and pitched away for the
unit to allow for proper drainage. This connection must
meet all local plumbing/building codes.
Pitch the unit toward the drain as shown in Figure 2 to
improve the condensate drainage. On small units (less
than 8.8 kW), ensure 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. Design the depth of
the trap (water-seal) based upon the amount of ESP
capability of the blower (where 51mm of ESP capability
requires 51mm of trap depth). As a general rule, 38mm
trap depth is the minimum.
Each unit must be installed with its own individual trap
and connection to the condensate line (main) or riser.
Provide a means to fl 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.

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 airfl ow through the unit during operation.
Air fl ow through the unit MUST be at or above the
minimum stated airfl ow 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 Figure 8 for vertical duct system details. A
fl 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 fi berglass duct liner or be constructed from
ductboard for the fi rst few feet. Application of the unit
to uninsulated ductwork in an unconditioned space is
not recommended, as the unit’s performance may 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 fl ow is a problem, the blower speed can be
changed. For airfl ow charts, consult submittal data for
the series and model of the specifi c unit.
If the unit is connected to existing ductwork, a
previous check should have been made to ensure that
the ductwork has the capacity to handle the airfl ow
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.

Vertical Installation
Vertical 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 mechanical
room/closet. Vertical units are typically installed in a
mechanical room or closet. 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 fi lter

access panel screws that would be diffi cult to remove
after the unit is installed should be removed prior to
setting the 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 10mm to 13mm in
thickness. Extend the pad beyond all four edges
of the unit.
2. Provide adequate clearance for fi lter replacement
and drain pan cleaning. Do not block fi 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 closet or mechanical room. Space should be
suffi cient to allow removal of the unit, if necessary.
5.
In limited side access installations, pre-removal of the

Vertical Installation
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 baffl e 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.
Condensate Piping for Vertical Units - A condensate
line must be installed and pitched away from the unit to
allow for proper drainage. This connection must meet
all local plumbing/building codes. 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 fl ush
or blow out the condensate drain line. Do not install
units with a common trap and/or vent.

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 fl 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 fl 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).
Pipe joint compound is not necessary when Tefl on
®
thread tape is pre-applied to hose assemblies or
when fl ared-end connections are used. If pipe joint
compound is preferred, use compound only in small
amounts on the external pipe threads of the fi tting
adapters. Prevent sealant from reaching the fl ar ed
surfaces of the joint.
Note: When antifreeze is used in the loop, ensure
that it is compatible with the Tefl on tape or pipe
joint compound that is applied.
Maximum allowable torque for brass fi ttings is 41 N-m.
If a torque wrench is not available, tighten fi nger-tight
plus one quarter turn. Tighten steel fi ttings
as necessary.
Optional pressure-rated hose assemblies designed
specifi cally for use with ClimateMaster units are
available. Similar hoses can be obtained from alternate
suppliers. Supply and return hoses are fi tted with
swivel-joint fi 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.
A backup wrench is required when tightening water
connections to prevent water line damage for TC Series
equipment. TS Series equipment has water connections
secured to the corner post.

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.

CAUTION! Piping must comply with all applicable codes.
WARNING! Polyolester Oil, commonly known as POE
oil, is a synthetic oil used in many refrigeration systems
including those with HFC-410A refrigerant. POE oil, if it
ever comes in contact with PVC or CPVC piping, may
cause failure of the PVC/CPVC. PVC/CPVC piping should
never be used as supply or return water piping with water
source heat pump products containing HFC-410A as
system failures and property damage may result.
