General Information
WARNING! To avoid the release of refrigerant into the
atmosphere, the refrigerant circuit of this unit must be
serviced only by technicians who meet local, state, and
federal prociency requirements.
WARNING! All refrigerant discharged from this unit must
be recovered WITHOUT EXCEPTION. Technicians must
follow industry accepted guidelines and all local, state, and
federal statutes for the recovery and disposal of refrigerants.
If a compressor is removed from this unit, refrigerant circuit
oil will remain in the compressor. To avoid leakage of
compressor oil, refrigerant lines of the compressor must be
sealed after it is removed.
CAUTION! To avoid equipment damage, DO NOT use
these units as a source of heating or cooling during the
construction process. The mechanical components and
lters can quickly become clogged with construction dirt and
debris, which may cause system damage and void product
warranty.
⚠ WARNING! ⚠
⚠ WARNING! ⚠
⚠ WARNING! ⚠
⚠ WARNING! ⚠
⚠ CAUTION! ⚠
WARNING! The EarthPure®Application and Service Manual
should be read and understood before attempting to service
refrigerant circuits with HFC-410A.
Storage
Pre-Installation
Inspection - Upon receipt of the equipment, carefully check
the shipment against the bill of lading. Make sure all units
have been received. Inspect the packaging of each unit, and
inspect each unit for damage. Ensure that the carrier makes
proper notation of any shortages or damage on all copies of
the freight bill and completes a common carrier inspection
report. Concealed damage not discovered during unloading
must be reported to the carrier within 15 days of receipt of
shipment. If not led within 15 days, the freight company can
deny the claim without recourse. Note: It is the responsibility
of the purchaser to le all necessary claims with the carrier.
Notify your equipment supplier of all damage within fteen
(15) days of shipment.
Storage - Equipment should be stored in its original
packaging in a clean, dry area. Store units in an upright
position at all times.
Unit Protection - Cover units on the job site with either the
original packaging or an equivalent protective covering. Cap
the open ends of pipes stored on the job site. In areas where
painting, plastering, and/or spraying has not been completed,
all due precautions must be taken to avoid physical damage
to the units and contamination by foreign material. Physical
damage and contamination may prevent proper start-up and
may result in costly equipment clean-up.
Examine all pipes, ttings, and valves before installing
any of the system components. Remove any dirt or debris
found in or on these components.
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 con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.
Safety
Warnings, cautions and notices appear throughout this
manual. Read these items carefully before attempting any
installation, service or troubleshooting of the equipment.
DANGER: Indicates an immediate hazardous situation,
which if not avoided will result in death or serious injury.
DANGER labels on unit access panels must be observed.
WARNING: Indicates a potentially hazardous situation,
which, if not avoided, could result in death or serious
injury.
CAUTION: Indicates a potentially hazardous situation or
an unsafe practice, which, if not avoided, could result in
minor or moderate injury or product or property damage.
NOTICE: Notication of installation, operation or
maintenance information, which is important, but which is
not hazard-related.
WARNING! The installation of water-source heat pumps 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.

CAUTION! All three phase scroll compressors must have
direction of rotation veried at start-up. Veri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
signicantly reduce performance, reliability, and service life.
Always move and store units in an upright position. Tilting
units on their sides will cause equipment damage.
⚠ CAUTION! ⚠
⚠ CAUTION! ⚠
⚠ 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.
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 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. Some airow patterns and some control box
locations are eld convertible. Locate the conversion
section of this IOM.

Horizontal Installation
Figure 1: Hanger Bracket
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 suf cient room to make water, electrical, and
duct connection(s). Allow 91 cm clearance for servicing
unit through all access panels.
If the unit is located in a con 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 dif 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.
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 speci 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 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.
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  nal hanger bracket
attachment and unit suspension. See Figure 1a.
Use four (4)  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, lter rails are the industry
standard and are included on ClimateMaster commercial
heat pumps for the purposes of holding the lter only. For
ducted return applications, the lter rail must be removed
and replaced with a duct ange or lter frame. Canvas
or exible connectors should also be used to minimize
vibration between the unit and ductwork.

TCH Field Conversion of Air Discharge
Overview - Horizontal units can be eld converted
between straight (side) 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 - Field conversion must be completed on
the ground. If the unit is already hung it should be taken
down for the eld conversion. Place in a well-lighted area.
Conversion should only be attempted by a quali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 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 con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.

CAUTION! Ensure condensate line is pitched toward drain

⚠ CAUTION! ⚠
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 airow
through the unit during operation. Air ow through the
unit MUST be at or above the minimum stated air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 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
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 ow is
a problem, the blower speed can be changed. For airow
charts, consult submittal data for the series and model of
the speci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 air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.
Horizontal Units Condensate Piping - Pitch the unit
toward the drain as shown in Figure 2 to improve the
condensate drainage. 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 2 inches [51mm] of ESP capability requires
2 inches [51mm] of trap depth). As a general rule, 1-1/2
inch [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 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.

Vertical Location and Access
TC units are not designed for outdoor installation. Locate
the unit in an indoor area that allows enough space for
installation and for service personnel to perform typical
maintenance or repairs. TC units are typically installed in
a oor level closet or in a small mechanical room. Refer to
Figure 7 for an illustration of a typical installation. Install
units with adequate clearance to allow maintenance
and servicing. Conform to the following guidelines when
selecting unit location:
• Provide adequate clearance for filter replacement and
drain pan cleaning. DO NOT block filter access with
piping, conduit or other materials. Refer to submittal
drawing for Vertical Unit Dimensions.
• Provide access for fan and fan motor maintenance
and for servicing of the compressor and coils without
removal of the unit.
• Provide an unobstructed path to the unit within the
closet or mechanical room to enable removal of the unit
if necessary.
• Provide access to water valves and fittings, and
screwdriver access to the unit side panels, discharge
collar and all electrical connections
Figure 7: Typical Vertical Installation
Duct System Design & Installation Guidelines
The following application guidelines must be used
when installing TC units. Failure to follow these guide-
lines could result in unsatisfactory unit performance
and/or premature failure of some unit components.
ClimateMaster will not warrant, or accept responsibil-
ity for products which fail, have defects, damage or insuf-
cient performance as a result of improper application.
• The duct system must be sized to handle the
airflow quietly and must not exceed the maximum
allowable External Static Pressure. To maximize
sound attenuation metal supply and return ducts
should include internal insulation or be of duct board
construction for the first 10 feet or end of first
full-sized elbow.
• Install a flexible connector in all supply and return
air ducts close to the unit to inhibit sound transfer to
the ducts.
• Do not install uninsulated duct in an unconditioned
space. The unit performance will be adversely affected
and damage from condensate can occur.
