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.
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 filed
within 15 days, the freight company can deny the claim
without recourse.
Note: It is the responsibility of the purchaser to file all
necessary claims with the carrier. Notify your equipment
supplier of all damage within fifteen (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. Stack units a maximum of 3 units
high.
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.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
Tranquility ® Compact (TC) Series
R e v. : 0 2 / 0 4 / 1 3
Examine all pipes, fittings, 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
configurations 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 finished.
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-to-air
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. (No action is required for
compressors with rubber grommets.)
7. Some airflow patterns are field convertible (horizontal
units only). Locate the airflow 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.
CAUTION!
CAUTION! All three phase scroll compressors must have
direction of rotation verified at start-up. Verification 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!
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
significantly 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.
NOTICE! Failure to remove shipping brackets from
spring-mounted compressors will cause excessive
noise, and could cause component failure due to
added vibration.

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 filter and access panels.
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.
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 specific 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 fittings. 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.
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 soffit using field supplied, threaded
rods sized to support the weight of the unit.
Use four (4) field supplied threaded rods and factory
provided vibration isolators to suspend the unit. Hang
the unit clear of the floor slab above and support the
unit by the mounting bracket assemblies only. DO NOT
attach the unit flush with the floor 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.

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
e-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, filter rails are the industry
standard and are included on ClimateMaster commercial
heat pumps for the purposes of holding the filter only.
For ducted return applications, the filter rail must be
removed and replaced with a duct flange or filter rack.
Canvas or flexible connectors should also be used to
minimize vibration between the unit and ductwork.

Field Conversion of Air Discharge
Overview - Horizontal units can be field converted
between side (straight) and back (end) discharge using
the instructions below.
Figure 4: Left Return Side to Back
Remove Screws
Water
Connection End
Note: It is not possible to field convert return air
between left or right return models due to the
necessity of refrigeration copper piping changes.
Return Air
Preparation - It is best to field convert the unit on the
ground before hanging. If the unit is already hung it
should be taken down for the field 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. Re-route 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 ensure that the wheel
is not rubbing or obstructed.
7. Replace access panels.

that illustrations will be reversed.
Left vs. Right Return - It is not possible to field 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
configuration 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.

Condensate Piping
Duct System Installation
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 2.5 tons/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 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 flush 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 airflow
through the unit during operation. Air flow through
the unit MUST be at or above the minimum stated
airflow 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 flexible 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 fiberglass duct
liner or be constructed from ductboard for the first 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 flow
is a problem, the blower speed can be changed. For
airflow charts, consult submittal data for the series and
model of the specific 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 airflow 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.

* 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.
CAUTION!
CAUTION! Ensure condensate line is pitched toward drain

1. Install the unit on a piece of rubber, neoprene orother
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 filter replacement
and drain pan cleaning. Do not block filter 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 sufficient
to allow removal of the unit, if necessary.
5. In limited side access installations, pre-removal of the
control box side mounting screws will allow control
box removal for future servicing.
6. Provide access to water valves and fittings and
screwdriver access to the unit side panels, discharge
collar and all electrical connections.

standard and are included on ClimateMaster commercial
heat pumps for the purposes of holding the filter only. For
ducted return applications, the filter rail must be removed
and replaced with a duct flange or filter rack. Canvas
or flexible connectors should also be used to minimize
vibration between the unit and ductwork.

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
baffle 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

Notice! Units with clear plastic drain lines should have
regular maintenance (as required) to avoid buildup of
debris, especially in new construction.
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 flush 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 flushing.
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 flow 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 Teflon®
thread tape is pre-applied to hose assemblies or when
flared-end connections are used. If pipe joint compound
is preferred, use compound only in small amounts on
the external pipe threads of the fitting adapters. Prevent
sealant from reaching the flared surfaces of the joint.
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 on TC Series units to prevent water line
damage.
WARNING!
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 CPVS 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.
CAUTION!
CAUTION! Corrosive system water requires corrosion
resistant fittings 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.

Water-Loop Heat Pump Applications
Commercial Water Loop Applications
Commercial systems typically include a number of
units connected to a common piping system. Any unit
plumbing maintenance work can introduce air into the
piping system; therefore air elimination equipment
is a major portion of the mechanical room plumbing.
Consideration should be given to insulating the
piping surfaces to avoid condensation. ClimateMaster
recommends unit insulation any time the water
temperature is expected to be below 60ºF (15.6ºC). Metal
to plastic threaded joints should never be used due to
their tendency to leak over time.
Teflon® tape thread sealant is recommended to
minimize internal fouling of the heat exchanger. Do
not over tighten connections and route piping so as
not to interfere with service or maintenance access.
Hose kits are available from ClimateMaster in different
configurations as shown in Figure 12 for connection
between the unit and the piping system. Depending
upon selection, hose kits may include shut off valves,
P/T plugs for performance measurement, high pressure
stainless steel braided hose, “Y” type strainer with blow
down valve, and/or “J” type swivel connection. Balancing
valves and an external low pressure drop solenoid valve
for use in variable speed pumping systems may also be
included in the hose kit.
The piping system should be flushed to remove dirt,
piping chips, and other foreign material prior to
operation (see “Piping System Cleaning and Flushing
Procedures” in this manual). The flow rate is usually set
between 2.25 and 3.5 gpm per ton [2.9 and 4.5 l/m per
kW] of cooling capacity. ClimateMaster recommends 3
gpm per ton [3.9 l/m per kW] for most applications of
water loop heat pumps. To ensure proper maintenance
and servicing, P/T ports are imperative for temperature
and flow verification, as well as performance checks.
Water loop heat pump (cooling tower/boiler) systems
typically utilize a common loop, maintained between
60 - 90°F [16 - 32°C]. The use of a closed circuit evaporative
cooling tower with a secondary heat exchanger between
the tower and the water loop is recommended. If an
open type cooling tower is used continuously, chemical
treatment and filtering will be necessary.

Ground-Loop Heat Pump Applications
CAUTION!
CAUTION! The following instructions represent industry
accepted installation practices for closed loop earth coupled
heat pump systems. Instructions are provided to assist the
contractor in installing trouble free ground loops. These
instructions are recommendations only. State/provincial
and local codes MUST be followed and installation 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!
CAUTION! Ground loop applications require extended range
equipment and optional refrigerant/water circuit insulation.
Pre-Installation
Prior to installation, locate and mark all existing
underground utilities, piping, etc. Install loops for new
construction before sidewalks, patios, driveways, and other
construction has begun. During construction, accurately
mark all ground loop piping on the plot plan as an aid in
avoiding potential future damage to the installation.
Piping Installation
The typical closed loop ground source system is shown in
Figure 13. All earth loop piping materials should be limited
to polyethylene fusion only for in-ground sections of the
loop. Galvanized or steel fittings should not be used at any
time due to their tendency to corrode. All plastic to metal
threaded fittings should be avoided due to their potential
to leak in earth coupled applications. A flanged fitting
should be substituted. P/T plugs should be used so that
flow can be measured using the pressure drop of the unit
heat exchanger.
Earth loop temperatures can range between 25 and 110°F
[-4 to 43°C]. Flow rates between 2.25 and 3 gpm [2.41 to
3.23 l/m per kW] of cooling capacity is recommended in
these applications.
Test individual horizontal loop circuits before backfilling.
Test vertical U-bends and pond loop assemblies prior to
installation. Pressures of at least 100 psi [689 kPa] should
be used when testing. Do not exceed the pipe pressure
rating. Test entire system when all loops are assembled.
Flushing the Earth Loop
Upon completion of system installation and testing, flush
the system to remove all foreign objects and purge to
remove all air.
Antifreeze
In areas where minimum entering loop temperatures
drop below 40°F [5°C] or where piping will be routed
through areas subject to freezing, antifreeze is required.
Alcohols and glycols are commonly used as antifreeze;
however your local sales office should be consulted to
determine the antifreeze best suited to your area. Freeze
protection should be maintained to 15°F [9°C] below
the lowest expected entering loop temperature. For
example, if 30°F [-1°C] is the minimum expected entering
loop temperature, the leaving loop temperature would
be 22 to 25°F [-6 to -4°C] and freeze protection should be
at 15°F [-10°C]. Calculation is as follows:
30°F - 15°F = 15°F [-1°C - 9°C = -10°C].
All alcohols should be premixed and pumped from
a reservoir outside of the building when possible or
introduced under the water level to prevent fumes.
Calculate the total volume of fluid in the piping system.
Then use the percentage by volume shown in table
2 for the amount of antifreeze needed. Antifreeze
concentration should be checked from a well mixed
sample using a hydrometer to measure specific gravity.
Low Water Temperature Cutout Setting - CXM Control
When antifreeze is selected, the FP1 jumper (JW3) should
be clipped to select the low temperature (antifreeze
10.0°F [-12.2°C]) setpoint and avoid nuisance faults (see

manual). Note: Low water temperature operation
requires extended range equipment.

Ground-Water Heat Pump Applications
Open Loop - Ground Water Systems - Typical open
loop piping is shown in Figure 14. Shut off valves should
be included for ease of servicing. Boiler drains or other
valves should be “tee’d” into the lines to allow acid
flushing of the heat exchanger. Shut off valves should be
positioned to allow flow through the coax via the boiler
drains without allowing flow into the piping system.
P/T plugs should be used so that pressure drop and
temperature can be measured. Supply and return water
piping materials should be limited to copper, PE, or similar
material. PVC or CPVC should never be used as they are
incompatible with the POE oils used in HFC-410A products
and piping system failure and property damage may result.
WARNING!
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 CPVS 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.
Water quantity should be plentiful and of good quality.
Consult table 3 for water quality guidelines. The unit can
be ordered with either a copper or cupro-nickel water
heat exchanger. Consult Table 3 for recommendations.
Copper is recommended for closed loop systems and
open loop ground water systems that are not high
in mineral content or corrosiveness. In conditions
anticipating heavy scale formation or in brackish water, a
cupro-nickel heat exchanger is recommended. In ground
water situations where scaling could be heavy or where
biological growth such as iron bacteria will be present, an
open loop system is not recommended. Heat exchanger
coils may over time lose heat exchange capabilities due
to build up of mineral deposits. Heat exchangers must
only be serviced by a qualified technician, as acid and
special pumping equipment is 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
acid flushing. In some cases, the desuperheater
option should not be recommended due to hard water
conditions and additional maintenance required.
Water Quality Standards - Table 3 should be consulted
for water quality requirements. Scaling potential should
be assessed using the pH/Calcium hardness method.
If the pH <7.5 and the calcium hardness is less than
100 ppm, scaling potential is low. If this method yields
numbers out of range of those listed, the Ryznar Stability
and Langelier Saturation indecies should be calculated.
Use the appropriate scaling surface temperature for
the application, 150°F [66°C] for direct use (well water/
open loop); 90°F [32°F] for indirect use. A monitoring
plan should be implemented in these probable scaling
situations. Other water quality issues such as iron fouling,
corrosion prevention and erosion and clogging should be
referenced in Table 3.
Expansion Tank and Pump - Use a closed, bladder-type
expansion tank to minimize mineral formation due to
air exposure. The expansion tank should be sized to
provide at least one minute continuous run time of the
pump using its drawdown capacity rating to prevent
pump short cycling. Discharge water from the unit is not
contaminated in any manner and can be disposed of in
various ways, depending on local building codes (e.g.
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 Control Valve - Note the placement of the
water control valve in Figure 14. Always maintain water
pressure in the heat exchanger by placing the water
control valve(s) on the discharge line to prevent mineral
precipitation during the off-cycle. Pilot operated slow
closing valves are recommended to reduce water
hammer. If water hammer persists, a mini-expansion
tank can be mounted on the piping to help absorb the
excess hammer shock. Ensure that the total ‘VA’ draw
of the valve can be supplied by the unit transformer.
For instance, a slow closing valve can draw up to 35VA.
This can overload smaller 40 or 50 VA transformers
depending on the other controls in the circuit. A typical
pilot operated solenoid valve draws approximately 15VA
(see Figure 19). Note the special wiring diagrams for slow
closing valves (Figures 20 & 21).

Tranquility ® Compact (TC) Series
R e v. : 0 2 / 0 4 / 1 3
Ground-Water Heat Pump Applications
Flow Regulation - Flow regulation can be accomplished
by two methods. One method of flow regulation involves
simply adjusting the ball valve or water control valve on
the discharge line. Measure the pressure drop through
the unit heat exchanger, and determine flow rate from
Tables 8a through 8e. Since the pressure is constantly
varying, two pressure gauges may be needed. Adjust the
valve until the desired flow of 1.5 to 2 gpm per ton [2.0
to 2.6 l/m per kW] is achieved. A second method of flow
control requires a flow control device mounted on the
outlet of the water control valve. The device is typically
a brass fitting with an orifice of rubber or plastic material
that is designed to allow a specified flow rate. On
occasion, flow control devices may produce velocity noise
that can be reduced by applying some back pressure
from the ball valve located on the discharge line. Slightly
closing the valve will spread the pressure drop over both
devices, lessening the velocity noise.
Note: When EWT is below 50°F [10°C], 2 gpm per ton
(2.6 l/m per kW) is required.
Water Coil Low Temperature Limit Setting - For all
open loop systems the 30°F [-1.1°C] FP1 setting (factory
setting-water) should be used to avoid freeze damage to
the unit. See “Low Water Temperature Cutout Selection”
in this manual for details on the low limit setting.

Electrical - Power Wiring
WARNING!
WARNING! Disconnect electrical power source to prevent
injury or death from electrical shock.
CAUTION!
CAUTION! Use only copper conductors for field installed
electrical wiring. Unit terminals are not designed to accept
other types of conductors.
Electrical - Line Voltage - All field installed wiring,
including electrical ground, must comply with the
National Electrical Code as well as all applicable local
codes. Refer to the unit electrical data for fuse sizes.
Consult wiring diagram for field connections that must
be made by the installing (or electrical) contractor. All
final electrical connections must be made with a length
of flexible conduit to minimize vibration and sound
transmission to the building.
General Line Voltage Wiring - Be sure the available
power is the same voltage and phase 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.
Power Connection - Line voltage connection is made
by connecting the incoming line voltage wires to the
“L” side of the contractor as shown in Figure 15. Consult
electrical data tables for correct fuse size.
Transformer - All 208/230 voltage units are factory wired
for 208 volt. If supply voltage is 230 volt, installer must
rewire transformer. See wire diagram for connections.
Blower Speed Selection – Units with PSC Motor - PSC
(Permanent Split Capacitor) blower fan speed can be
changed by moving the blue wire on the fan motor
terminal block to the desired speed as shown in Figure
16. Most ClimateMaster units are shipped on the medium
speed tap. Consult submittal data or engineering design
guide for specific unit airflow tables. Typical unit design
delivers rated airflow at nominal static (0.15 in. w.g.
[37Pa]) on medium speed and rated airflow at a higher
static (0.4 to 0.5 in. w.g. [100 to 125 Pa]) on high speed for
applications where higher static is required. Low speed
will deliver approximately 85% of rated airflow at 0.10 in.
w.g. [25 Pa]. An optional high static blower is available on
some models.

Three phase wiring is similar except that all three
power wires are directly connected to the contactor.

Electrical - Power & Low Voltage Wiring
Special Note for AHRI Testing: To achieve rated
airflow for AHRI testing purposes on all PSC products,
it is necessary to change the fan speed to “HI” speed.
When the heat pump has experienced less than 100
operational hours and the coil has not had sufficient time
to be “seasoned”, it is necessary to clean the coil with a
mild surfactant such as Calgon to remove the oils left by
manufacturing processes and enable the condensate to
properly “sheet” off of the coil.

ELECTRICAL - LOW VOLTAGE WIRING
Thermostat Connections - The thermostat should be
wired directly to the CXM or DXM board. Figure 19
shows wiring. See “Electrical – Thermostat” for specific
terminal connections. Review the appropriate AOM
(Application, Operation and Maintenance) manual for
units with DDC controls.
Low Water Temperature Cutout Selection - The CXM/
DXM control allows the field selection of low water (or
water-antifreeze solution) temperature limit by clipping
jumper JW3, which changes the sensing temperature
associated with thermistor FP1. Note that the FP1
thermistor is located on the refrigerant line between
the coaxial heat exchanger and expansion device (TXV).
Therefore, FP1 is sensing refrigerant temperature, not
water temperature, which is a better indication of how
water flow rate/temperature is affecting the refrigeration
circuit.
The factory setting for FP1 is for systems using water
(30°F [-1.1°C] refrigerant temperature). In low water
temperature (extended range) applications with
antifreeze (most ground loops), jumper JW3 should be
clipped as shown in Figure 18 to change the setting to
10°F [-12.2°C] refrigerant temperature, a more suitable
temperature when using an antifreeze solution. All
ClimateMaster units operating with entering water
temperatures below 60°F [15.6°C] must include the
optional water/refrigerant circuit insulation package to
prevent internal condensation.

Accessory Connections
A terminal paralleling the compressor contactor coil
has been provided on the CXM/DXM control. Terminal
“A” is designed to control accessory devices, such as
water valves. Note: This terminal should be used only
with 24 Volt signals and not line voltage. Terminal “A” is
energized with the compressor contactor. See Figure 19
or the specific unit wiring diagram for details.

Component
Water Solenoid Valves - An external solenoid valve(s)
should be used on ground water installations to shut off
flow to the unit when the compressor is not operating.
A slow closing valve may be required to help reduce
water hammer. Figure 19 shows typical wiring for a 24VAC
external solenoid valve. Figures 20 and 21 illustrate
typical slow closing water control valve wiring for Taco
500 series (ClimateMaster P/N AVM) and Taco SBV
series valves. Slow closing valves take approximately
60 seconds to open (very little water will flow before 45
seconds). Once fully open, an end switch allows the
compressor to be energized. Only relay or triac based
electronic thermostats should be used with slow closing
valves. When wired as shown, the slow closing valve will
operate properly with the following notations:
1. The valve will remain open during a unit lockout.
2. The valve will draw approximately 25-35 VA through
the “Y” signal of the thermostat.

THE SMART SOLUTION FOR ENERGY EFFICIENCY

R e v. : 0 2 / 0 4 / 1 3
Electrical - Thermostat Wiring
Thermostat Installation - The thermostat should be
located on an interior wall in a larger room, away from
supply duct drafts. DO NOT locate the thermostat in
areas subject to sunlight, drafts or on external walls.
The wire access hole behind the thermostat may in
certain cases need to be sealed to prevent erroneous
temperature measurement. Position the thermostat
back plate against the wall so that it appears level and
so the thermostat wires protrude through the middle
of the back plate. Mark the position of the back plate
mounting holes and drill holes with a 3/16” (5mm) bit.
Install supplied anchors and secure plate to the wall.
Thermostat wire must be 18 AWG wire. Representative
thermostat wiring is shown in Figures 22 however, actual
wiring connections should be determined from the
thermostat IOM and or unit wiring diagram. Practically
any heat pump thermostat will work with ClimateMaster
units, provided it has the correct number of heating and
cooling stages.

CXM Controls
CXM Control - For detailed control information,
see CXM or DXM Application, Operation and
Maintenance (AOM) manual (part # 97B0003N12 or part
#97B0003N13).
Field Selectable Inputs - Test mode: Test mode allows
the service technician to check the operation of the
control in a timely manner. By momentarily shorting the
test terminals, the CXM control enters a 20 minute test
mode period in which all time delays are sped up 15
times. Upon entering test mode, the status LED will flash
a code representing the last fault. For diagnostic ease at
the thermostat, the alarm relay will also cycle during test
mode. The alarm relay will cycle on and off similar to the
status LED to indicate a code representing the last fault,
at the thermostat. Test mode can be exited by shorting
the test terminals for 3 seconds.
Retry Mode: If the control is attempting a retry of a fault,
the status LED will slow flash (slow flash = one flash every
2 seconds) to indicate the control is in the process of
retrying.
Field Configuration Options - Note: In the following
field configuration options, jumper wires should be
clipped ONLY when power is removed from the CXM
control.
Water coil low temperature limit setting: Jumper 3 (JW3FP1 Low Temp) provides field selection of temperature
limit setting for FP1 of 30°F or 10°F [-1°F or -12°C]
(refrigerant temperature).
Not Clipped = 30°F [-1°C]. Clipped = 10°F [-12°C].
Air coil low temperature limit setting: Jumper 2 (JW2FP2 Low Temp) provides field selection of temperature
limit setting for FP2 of 30°F or 10°F [-1°F or -12°C]
(refrigerant temperature). Note: This jumper should
only be clipped under extenuating circumstances, as
recommended by the factory.
Not Clipped = 30°F [-1°C]. Clipped = 10°F [-12°C].
Alarm relay setting: Jumper 1 (JW1-AL2 Dry) provides
field selection of the alarm relay terminal AL2 to
be jumpered to 24VAC or to be a dry contact (no
connection).
Not Clipped = AL2 connected to R. Clipped = AL2 dry
contact (no connection).
DIP Switches - Note: In the following field configuration
options, DIP switches should only be changed when
power is removed from the CXM control.
DIP switch 1: Unit Performance Sentinel Disable provides field selection to disable the UPS feature.
On = Enabled. Off = Disabled.
DIP switch 2: Stage 2 Selection - provides selection of
whether compressor has an “on” delay. If set to stage
2, the compressor will have a 3 second delay before
energizing. Also, if set for stage 2, the alarm relay will
NOT cycle during test mode.
On = Stage 1. Off = Stage 2
DIP switch 3: Not Used.
DIP switch 4: DDC Output at EH2 - provides selection for
DDC operation. If set to “DDC Output at EH2,” the EH2
terminal will continuously output the last fault code of
the controller. If set to “EH2 normal,” EH2 will operate as
standard electric heat output.
On = EH2 Normal. Off = DDC Output at EH2.
Note: Some CXM controls only have a 2 position DIP
switch package. If this is the case, this option can be
selected by clipping the jumper which is in position 4
of SW1.
Jumper not clipped = EH2 Normal. Jumper clipped =
DDC Output at EH2.
DIP switch 5: Factory Setting - Normal position is “On.”
Do not change selection unless instructed to do so by
the factory.

DXM Controls
1.3 - Thermostat type (heat pump or heat/cool): DIP 1.3
provides selection of thermostat type. Heat pump or
heat/cool thermostats can be selected. When in heat/
cool mode, Y1 is the input call for cooling stage 1; Y2 is
the input call for cooling stage 2; W1 is the input call for
heating stage 1; and O/W2 is the input call for heating
stage 2. In heat pump mode, Y1 is the input call for
compressor stage 1; Y2 is the input call for compressor
stage 2; W1 is the input call for heating stage 3 or
emergency heat; and O/W2 is the input call for reversing
valve (heating or cooling, depending upon DIP 1.4).
On = Heat Pump. Off = Heat/Cool.
1.4 - Thermostat type (O/B): DIP 1.4 provides selection of
thermostat type for reversing valve activation. Heat pump
thermostats with “O” output (reversing valve energized
for cooling) or “B” output (reversing valve energized for
heating) can be selected with DIP 1.4.
On = HP stat with “O” output for cooling. Off = HP stat
with “B” output for heating.
1.5 - Dehumidification mode: DIP 1.5 provides
selection of normal or dehumidification fan mode. In
dehumidification mode, the fan speed relay will remain
off during cooling stage 2. In normal mode, the fan speed
relay will turn on during cooling stage 2.
On = Normal fan mode. Off = Dehumidification mode.
1.6 - DDC output at EH2: DIP 1.6 provides selection for
DDC operation. If set to “DDC Output at EH2,” the EH2
terminal will continuously output the last fault code of
the controller. If set to “EH2 normal,” EH2 will operate as
standard electric heat output.
On = EH2 Normal. Off = DDC Output at EH2.
1.7 - Boilerless operation: DIP 1.7 provides selection of
boilerless operation. In boilerless mode, the compressor
is only used for heating when FP1 is above the
temperature specified by the setting of DIP 1.8. Below
DIP 1.8 setting, the compressor is not used and the
control goes into emergency heat mode, staging on EH1
and EH2 to provide heating.
On = normal. Off = Boilerless operation.
1.8 - Boilerless changeover temperature: DIP 1.8 provides
selection of boilerless changeover temperature setpoint.
Note that the FP1 thermistor is sensing refrigerant
temperature between the coaxial heat exchanger and the
expansion device (TXV). Therefore, the 50°F [10°C] setting
is not 50°F [10°C] water, but approximately 60°F [16°C]
EWT.
On = 50°F [10°C]. Off = 40°F [16°C].
DIP Package #2 (S2) - DIP Package #2 has 8 switches and

Safety Features - CXM and DXM Controls
Safety Features – CXM/DXM Control
The safety features below are provided to protect
the compressor, heat exchangers, wiring, and other
components from damage caused by operation outside
of design conditions.
Anti-short cycle protection: The control features a 5
minute anti-short cycle protection for the compressor.
Note: The 5 minute anti-short cycle also occurs at
power up.
Random start: The control features a random start upon
power up of 5-80 seconds.
Fault Retry: In Fault Retry mode, the Status LED begins
slowly flashing to signal that the control is trying to
recover from a fault input. The control will stage off the
outputs and then “try again” to satisfy the thermostat
input call. Once the thermostat input call is satisfied,
the control will continue on as if no fault occurred. If 3
consecutive faults occur without satisfying the thermostat
input call, the control will go into “lockout” mode. The
last fault causing the lockout will be stored in memory
and can be viewed at the “fault” LED (DXM board) or
by going into test mode (CXM board). Note: LT1/LT2
faults are factory set at only one try.
Lockout: In lockout mode, the status LED will begin fast
flashing. The compressor relay is turned off immediately.
Lockout mode can be “soft” reset by turning off the
thermostat (or satisfying the call). A “soft” reset keeps
the fault in memory but resets the control. A “hard”
reset (disconnecting power to the control) resets the
control and erases fault memory.
Lockout with emergency heat: While in lockout mode,
if W becomes active (CXM), emergency heat mode will
occur. If DXM is configured for heat pump thermostat
type (DIP 1.3), emergency heat will become active if O/
W2 is energized.
High pressure switch: When the high pressure switch
opens due to high refrigerant pressures, the compressor
relay is de-energized immediately since the high pressure
switch is in series with the compressor contactor coil. The
high pressure fault recognition is immediate (does not
delay for 30 continuous seconds before de-energizing
the compressor).
High pressure lockout code = 2
Example: 2 quick flashes, 10 sec pause, 2 quick flashes, 10
sec. pause, etc.
Low pressure switch: The low pressure switch must be open
and remain open for 30 continuous seconds during “on”
cycle to be recognized as a low pressure fault. If the low
pressure switch is open for 30 seconds prior to compressor
power up it will be considered a low pressure (loss of charge)
fault. The low pressure switch input is bypassed for the initial
120 seconds of a compressor run cycle.
32
Low pressure lockout code = 3
Water coil low temperature (LT1): The LT1 thermistor
temperature must be below the selected low
temperature limit setting for 30 continuous seconds
during a compressor run cycle to be recognized as a LT1
fault. The LT1 input is bypassed for the initial 120 seconds
of a compressor run cycle. LT1 is set at the factory for one
try. Therefore, the control will go into lockout mode once
the LT1 fault has occurred.
LT1 lockout code = 4
Air coil low temperature (LT2): The LT2 thermistor
temperature must be below the selected low
temperature limit setting for 30 continuous seconds
during a compressor run cycle to be recognized as a LT2
fault. The LT2 input is bypassed for the initial 60 seconds
of a compressor run cycle. LT2 is set at the factory for one
try. Therefore, the control will go into lockout mode once
the LT2 fault has occurred.
LT2 lockout code = 5
Condensate overflow: The condensate overflow sensor
must sense overflow level for 30 continuous seconds to
be recognized as a CO fault. Condensate overflow will be
monitored at all times.
CO lockout code = 6
Over/under voltage shutdown: An over/under voltage
condition exists when the control voltage is outside the
range of 19VAC to 30VAC. Over/under voltage shut
down is a self-resetting safety. If the voltage comes back
within range for at least 0.5 seconds, normal operation
is restored. This is not considered a fault or lockout. If
the CXM/DXM is in over/under voltage shutdown for 15
minutes, the alarm relay will close.
Over/under voltage shut down code = 7
Unit Performance Sentinel-UPS (patent pending): The
UPS feature indicates when the heat pump is operating
inefficiently. A UPS condition exists when:
a. In heating mode with compressor energized, LT2 is greater
than 125°F [52°C] for 30 continuous seconds, or:
b. In cooling mode with compressor energized, LT1 is greater
than 125°F [52°C] for 30 continuous seconds, or:
c. In cooling mode with compressor energized, LT2 is less
than 40°F [4.5°C] for 30 continuous seconds.

R e v. : 0 2 / 0 4 / 1 3
Safety Features - CXM and DXM Controls
If a UPS condition occurs, the control will immediately
go to UPS warning. The status LED will remain on as if
the control is in normal mode. Outputs of the control,
excluding LED and alarm relay, will NOT be affected
by UPS. The UPS condition cannot occur during a
compressor off cycle. During UPS warning, the alarm
relay will cycle on and off. The cycle rate will be “on” for
5 seconds, “off” for 25 seconds, “on” for 5 seconds, “off”
for 25 seconds, etc.
UPS warning code = 8
Swapped LT1/LT2 thermistors: During test mode, the
control monitors to see if the FP1 and FP2 thermistors are
in the appropriate places. If the control is in test mode,
the control will lockout with code 9 after 30 seconds if:
CXM/DXM Control Start-up Operation
The control will not operate until all inputs and safety
controls are checked for normal conditions. The compressor will have a 5 minute anti-short cycle delay at
power-up. The first time after power-up that there is a
call for compressor, the compressor will follow a 5 to 80
second random start delay. After the random start delay
and anti-short cycle delay, the compressor relay will be
energized. On all subsequent compressor calls, the random start delay is omitted.
a. The compressor is on in the cooling mode and the LT1
sensor is colder than the LT2 sensor, or:
b. The compressor is on in the heating mode and the LT2
sensor is colder than the LT1 sensor.
Swapped LT1/LT2 thermistor code = 9.
ESD (DXM only): The ESD (Emergency Shut Down)
mode can be enabled from an external common signal
to terminal ESD to shut down the unit. The green status
light will flash code 3 when the unit is in ESD mode.
ESD mode = code 3 (green “status” LED)
Diagnostic Features
The LED on the CXM board advises the technician of the
current status of the CXM control. The LED can display
either the current CXM mode or the last fault in memory
if in test mode. If there is no fault in memory, the LED will
flash Code 1 (when in test mode).
The green status LED and red fault LED on the DXM
board advise the technician of the current status of the
DXM control. The status LED will indicate the current
mode that the DXM control is in. The fault LED will
ALWAYS flash a code representing the LAST fault in
memory. If there is no fault in memory, the fault LED will
flash Code 1. The yellow test LED will turn on when in
test mode. CAUTION: Do not restart units without
inspection and remedy of faulting condition. Damage
may occur.

Unit Starting and Operating Conditions
Operating Limits
Environment – Units are designed for indoor installation only. 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).
Power Supply – A voltage variation of +/– 10% of nameplate utilization voltage is acceptable.
Determination of operating limits is dependent primarily upon three factors: 1) return air temperature. 2) water
temperature, and 3) ambient temperature. When any one of these factors is at minimum or maximum levels, the
other two factors should be at normal levels to ensure proper unit operation. Extreme variations in temperature and
humidity and/or corrosive water or air will adversely affect unit performance, reliability, and service life. Consult Table
7 for operating limits.

Piping System Cleaning and Flushing
Piping System Cleaning and Flushing - Cleaning and
flushing the WLHP piping system is the single most
important step to ensure proper start-up and continued
efficient operation of the system.
Follow the instructions below to properly clean and
flush the system:
1. Ensure that electrical power to the unit is
disconnected.
2. Install the system with the supply hose connected
directly to the return riser valve. Use a single length
of flexible hose.
3. Open all air vents. Fill the system with water. DO
NOT allow system to overflow. Bleed all air from the
system. Pressurize and check the system for leaks
and repair as appropriate.
4. Verify that all strainers are in place (ClimateMaster
recommends a strainer with a #20 stainless steel
wire mesh). Start the pumps, and systematically
check each vent to ensure that all air is bled from
the system.
5. Verify that make-up water is available. Adjust makeup water as required to replace the air which was
bled from the system. Check and adjust the water/air
level in the expansion tank.
6. Set the boiler to raise the loop temperature to
approximately 85°F [29°C]. Open a drain at the
lowest point in the system. Adjust the make-up water
replacement rate to equal the rate of bleed.
7. Refill the system and add trisodium phosphate
in a proportion of approximately one pound per
150 gallons (.8 kg per 1000 l ) of water (or other
equivalent approved cleaning agent). Reset the
boiler to raise the loop temperature to 100°F [38°C].
Circulate the solution for a minimum of 8 to 24 hours.
At the end of this period, shut off the circulating
pump and drain the solution. Repeat system
cleaning if desired.
8. When the cleaning process is complete, remove the
short-circuited hoses. Reconnect the hoses to the
proper supply, and return the connections to each of
the units. Refill the system and bleed off all air.
9. Test the system pH with litmus paper. The system
water should be in the range of pH 6.0 - 8.5 (see
table 3). Add chemicals, as appropriate to maintain
neutral pH levels.
10. When the system is successfully cleaned, flushed,
refilled and bled, check the main system panels,
safety cutouts and alarms. Set the controls to
properly maintain loop temperatures.
CAUTION!
CAUTION! DO NOT use “Stop Leak” or similar chemical
agent in this system. Addition of chemicals of this type to
the loop water will foul the heat exchanger and inhibit unit
operation.
Note: The manufacturer strongly recommends all
piping connections, both internal and external to the
unit, be pressure tested by an appropriate method
prior to any finishing of the interior space or before
access to all connections is limited. Test pressure may
not exceed the maximum allowable pressure for the
unit and all components within the water system.
The manufacturer will not be responsible or liable
for damages from water leaks due to inadequate or
lack of a pressurized leak test, or damages caused
by exceeding the maximum pressure rating during
installation.

Unit and System Checkout
WARNING!
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 CPVS 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.
Unit and System Checkout
BEFORE POWERING SYSTEM, please check the following:
UNIT CHECKOUT
Balancing/shutoff valves: Ensure that all isolation
valves are open and water control valves are wired.
Line voltage and wiring: Verify that voltage is within
an acceptable range for the unit and wiring and
fuses/breakers are properly sized. Verify that low
voltage wiring is complete.
Unit control transformer: Ensure that transformer
has the properly selected voltage tap.
Entering water and air: Ensure that entering water
and air temperatures are within operating limits of
Table 8a-b.
Low water temperature cutout: Verify that low water
temperature cut-out on the CXM/DXM control is
properly set.
Unit fan: Manually rotate fan to verify free rotation
and ensure that blower wheel is secured to the
motor shaft. Be sure to remove any shipping
supports if needed. DO NOT oil motors upon startup. Fan motors are pre-oiled at the factory. Check
unit fan speed selection and compare to design
requirements.
Condensate line: Verify that condensate line is
open and properly pitched toward drain.
Water flow balancing: Record inlet and outlet water
temperatures for each heat pump upon startup.
This check can eliminate nuisance trip outs and
high velocity water flow that could erode heat
exchangers.
Unit air coil and filters: Ensure that filter is clean and
accessible. Clean air coil of all manufacturing oils.
Unit controls: Verify that CXM or DXM field
selection options are properly set.
36
SYSTEM CHECKOUT
System water temperature: Check water temperature
for proper range and also verify heating and cooling
set points for proper operation.
System pH: Check and adjust water pH if necessary
to maintain a level between 6 and 8.5. Proper pH
promotes longevity of hoses and fittings (see table 3).
System flushing: Verify that all hoses are connected
end to end when flushing to ensure that debris
bypasses the unit heat exchanger, water valves and
other components. Water used in the system must be
potable quality initially and clean of dirt, piping slag,
and strong chemical cleaning agents. Verify that all
air is purged from the system. Air in the system can
cause poor operation or system corrosion.
Cooling tower/boiler: Check equipment for proper
setpoints and operation.
Standby pumps: Verify that the standby pump is
properly installed and in operating condition.
System controls: Verify that system controls function
and operate in the proper sequence.
Low water temperature cutout: Verify that low water
temperature cut-out controls are provided for the
outdoor portion of the loop. Otherwise, operating
problems may occur.
System control center: Verify that the control center
and alarm panel have appropriate setpoints and are
operating as designed.
Miscellaneous: Note any questionable aspects of the
installation.
CAUTION!
CAUTION! Verify that ALL water control valves are open and
allow water flow prior to engaging the compressor. Freezing
of the coax or water lines can permanently damage the heat
pump.
CAUTION!
CAUTION! To avoid equipment damage, DO NOT
leave system filled in a building without heat during the
winter unless antifreeze is added to the water loop. Heat
exchangers never fully drain by themselves and will freeze
unless winterized with antifreeze.
NOTICE! Failure to remove shipping brackets from
spring-mounted compressors will cause excessive
noise, and could cause component failure due to
added vibration.

Unit Start-Up Procedure
Unit Start-up Procedure
1. Turn the thermostat fan position to “ON”. Blower
should start.
2. Balance air flow at registers.
3. Adjust all valves to their full open positions. Turn on
the line power to all heat pumps.
4. Room temperature should be within the minimummaximum ranges of table 7. During start-up checks,
loop water temperature entering the heat pump
should be between 60°F [16°C] and 95°F [35°C].
5. Two factors determine the operating limits
of ClimateMaster heat pumps, (a) return air
temperature, and (b) water temperature. When any
one of these factors is at a minimum or maximum
level, the other factor must be at normal level to
ensure proper unit operation.
a. Adjust the unit thermostat to the warmest setting.
Place the thermostat mode switch in the “COOL”
position. Slowly reduce thermostat setting until
the compressor activates.
b. Check for cool air delivery at the unit grille within a
few minutes after the unit has begun to operate.
Note: Units have a five minute time delay in
the control circuit that can be eliminated on the
CXM/DXM control board as shown in Figure 23.
See controls description for details.
c. Verify that the compressor is on and that the water
flow rate is correct by measuring pressure drop
through the heat exchanger using the P/T plugs
and comparing to table 9.
d. Check the elevation and cleanliness of the
condensate lines. Dripping may be a sign of a
blocked line. Check that the condensate trap is
filled to provide a water seal.
e. Refer to table 11. Check the temperature of both
entering and leaving water. If temperature is within
range, proceed with the test. Verify correct water
flow by comparing unit pressure drop across the
heat exchanger versus the data in table 9. Heat of
rejection (HR) can be calculated and compared to
submittal data capacity pages. The formula for HR
for systems with water is as follows:
HR (Btuh) = TD x GPM x 500,where TD is the
temperature difference between the entering and
leaving water, and GPM is the flow rate in U.S.
GPM, determined by comparing the pressure drop
across the heat exchanger to table 9. In S-I units,
the formula is as follows: HR (kW) = TD x l/s x 4.18.
f. Check air temperature drop across the air coil when
compressor is operating. Air temperature drop
should be between 15°F and 25°F [8°C and 14°C].
g. Turn thermostat to “OFF” position. A hissing noise
indicates proper functioning of the reversing valve.
6. Allow five (5) minutes between tests for pressure to
equalize before beginning heating test.
a. Adjust the thermostat to the lowest setting. Place
the thermostat mode switch in the “HEAT” position.
b. Slowly raise the thermostat to a higher
temperature until the compressor activates.
c. Check for warm air delivery within a few minutes
after the unit has begun to operate.
d. Refer to table 11. Check the temperature of both
entering and leaving water. If temperature is within
range, proceed with the test. If temperature is
outside of the operating range, check refrigerant
pressures and compare to table 10. Verify correct
water flow by comparing unit pressure drop across
the heat exchanger versus the data in table 9.
Heat of extraction (HE) can be calculated and
compared to submittal data capacity pages. The
formula for HE for systems with water is as follows:
HE (kW) = TD xGPM x 500, where TD is the
temperature difference between the entering
and leaving water, and l/s is the flow rate in U.S.
GPM, determined by comparing the pressure drop
across the heat exchanger to tables 10a through
10e. In S-I units, the formula is as follows: HE (kW)
= TD x l/s x 4.18.
e. Check air temperature rise across the air coil when
compressor is operating. Air temperature rise
should be between 20°F and 30°F [11°C and 17°C].
f. Check for vibration, noise, and water leaks.
7. If unit fails to operate, perform troubleshooting analysis
(see troubleshooting section). If the check described fails
to reveal the problem and the unit still does not operate,
contact a trained service technician to ensure proper
diagnosis and repair of the equipment.
8. When testing is complete, set system to maintain
desired comfort level.
9. BE CERTAIN TO FILL OUT AND FORWARD ALL WARRANTY
REGISTRATION PAPERS TO CLIMATEMASTER.
Note: If performance during any mode appears
abnormal, refer to the CXM/DXM section or
troubleshooting section of this manual. To obtain
maximum performance, the air coil should be cleaned
before start-up. A 10% solution of dishwasher
detergent and water is recommended.

Preventive Maintenance
Water Coil Maintenance - (Direct ground water
applications only) If the system is installed in an area with
a known high mineral content (125 P.P.M. or greater) in
the water, it is best to establish a periodic maintenance
schedule with the owner so the coil can be checked
regularly. Consult the well water applications section
of this manual for a more detailed water coil material
selection. Should periodic coil cleaning be necessary, use
standard coil cleaning procedures, which are compatible
with the heat exchanger material and copper water
lines. Generally, the more water flowing through the unit,
the less chance for scaling. Therefore, 1.5 gpm per ton
[1.6 l/m per kW] is recommended as a minimum flow.
Minimum flow rate for entering water temperatures
below 50°F [10°C] is 2.0 gpm per ton [2.2 l/m per kW].
Water Coil Maintenance - (All other water loop
applications) Generally water coil maintenance is not
needed for closed loop systems. However, if the piping
is known to have high dirt or debris content, it is best
to establish a periodic maintenance schedule with the
owner so the water coil can be checked regularly. Dirty
installations are typically the result of deterioration of iron
or galvanized piping or components in the system. Open
cooling towers requiring heavy chemical treatment and
mineral buildup through water use can also contribute
to higher maintenance. Should periodic coil cleaning be
necessary, use standard coil cleaning procedures, which
are compatible with both the heat exchanger material
and copper water lines. Generally, the more water flowing
through the unit, the less chance for scaling. However,
flow rates over 3 gpm per ton (3.9 l/m per kW) can
produce water (or debris) velocities that can erode the
heat exchanger wall and ultimately produce leaks.
Filters - Filters must be clean to obtain maximum
performance. Filters should be inspected every month
under normal operating conditions and be replaced
when necessary. Units should never be operated without
a filter.
Washable, high efficiency, electrostatic filters, when dirty,
can exhibit a very high pressure drop for the fan motor
and reduce air flow, resulting in poor performance. It is
especially important to provide consistent washing of
these filters (in the opposite direction of the normal air
flow) once per month using a high pressure wash similar
to those found at self-serve car washes.
44
Condensate Drain - In areas where airborne bacteria
may produce a “slimy” substance in the drain pan, it may
be necessary to treat the drain pan chemically with an
algaecide approximately every three months to minimize
the problem. The condensate pan may also need to be
cleaned periodically to ensure indoor air quality. The
condensate drain can pick up lint and dirt, especially with
dirty filters. Inspect the drain twice a year to avoid the
possibility of plugging and eventual overflow.
Compressor - Conduct annual amperage checks to
ensure that amp draw is no more than 10% greater than
indicated on the serial plate data.
Fan Motors - All units have lubricated fan motors. Fan
motors should never be lubricated unless obvious, dry
operation is suspected. Periodic maintenance oiling is
not recommended, as it will result in dirt accumulating in
the excess oil and cause eventual motor failure. Conduct
annual dry operation check and amperage check to
ensure amp draw is no more than 10% greater than
indicated on serial plate data.
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: Fin edges are sharp.
Cabinet - Do not allow water to stay in contact with the
cabinet for long periods of time to prevent corrosion of
the cabinet sheet metal. Generally, vertical cabinets are
set up from the floor a few inches [7 - 8 cm] to prevent
water from entering the cabinet. The cabinet can be
cleaned using a mild detergent.
Refrigerant System - To maintain sealed circuit integrity,
do not install service gauges unless unit operation
appears abnormal. Reference the operating charts for
pressures and temperatures. Verify that air and water
flow rates are at proper levels before servicing the
refrigerant circuit.

Note: Never connect refrigerant gauges during startup procedures. Conduct water-side analysis using P/T ports
to determine water flow and temperature difference. If water-side analysis shows poor performance, refrigerant
troubleshooting may be required. Connect refrigerant gauges as a last resort.

LIMITATION OF REMEDIES
In the event of a breach of the Limited Express Warranty, CM will only be obligated at CM’s option to repair the failed part or unit or to furnish a new or rebuilt part or unit in exchange for the part or unit which has failed. If
after written notice to CM’s factory in Oklahoma City, Oklahoma of each defect, malfunction or other failure and a reasonable number of attempts by CM to correct the defect, malfunction or other failure and the remedy fails
of its essential purpose, CM shall refund the purchase price paid to CM in exchange for the return of the sold good(s). Said refund shall be the maximum liability of CM. THIS REMEDY IS THE SOLE AND EXCLUSIVE
REMEDY OF THE BUYER OR THEIR PURCHASER AGAINST CM FOR BREACH OF CONTRACT, FOR THE BREACH OF ANY WARRANTY OR FOR CM’S NEGLIGENCE OR IN STRICT LIABILITY.
Limitation: This Limited Express Warranty is given in lieu of all other warranties.

This warranty does not cover and does not apply to: (1) Air Àlters, fuses, refrigerant, Áuids, oil; (2) Products relocated after initial installation; (3) Any portion or component of any system that is not supplied by CM, regardless
of the cause of the failure of such portion or component; (4) Products on which the unit identiÀcation tags or labels have been removed or defaced; (5) Products on which payment to CM is or has been in default; (6) Products
which have defects or damage which result from improper installation, wiring, electrical imbalance characteristics or maintenance; or are caused by accident, misuse or abuse, Àre, Áood, alteration or misapplication of the product; (7) Products which have defects or damage which result from a contaminated or corrosive air or liquid supply, operation at abnormal temperatures, or unauthorized opening of refrigerant circuit; (8) Mold, fungus or bacteria
damages; (9) Products subjected to corrosion or abrasion; (10) Products manufactured or supplied by others; (11) Products which have been subjected to misuse, negligence or accidents; (12) Products which have been operated
in a manner contrary to CM’s printed instructions; or (13) Products which have defects, damage or insufÀcient performance as a result of insufÀcient or incorrect system design or the improper application of CM’s products.
GRANT OF LIMITED EXPRESS WARRANTY
CM warrants CM products purchased and retained in the United States of America and Canada to be free from defects in material and workmanship under normal use and maintenance as follows: (1) All complete air conditioning, heating and/or heat pump units built or sold by CM for twelve (12) months from date of unit start up or eighteen (18) months from date of shipment (from factory), whichever comes Àrst; (2) Repair and replacement parts,

NO WARRANTY OF MERCHANTABILITY OF THE GOODS OR OF THE FITNESS OF THE GOODS FOR ANY PARTICULAR PURPOSE.
It is expressly understood that unless a statement is speciÀcally identiÀed as a warranty, statements made by Climate Master, Inc., a Delaware corporation, (“CM”) or its representatives, relating to CM’s products, whether oral,
