General Information
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: Notification of installation, operation or
maintenance information, which is important, but which is
not hazard-related.
⚠ WARNING! ⚠
WARNING! The EarthPure® Application and Service Manual
should be read and understood before attempting to service
refrigerant circuits with HFC-410A.
⚠ WARNING! ⚠
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 proficiency requirements.
⚠ CAUTION! ⚠
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
filters can quickly become clogged with construction dirt and
debris, which may cause system damage and void product
warranty.
⚠ WARNING! ⚠
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.
4
⚠ WARNING! ⚠
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.
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.
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, 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.

⚠ CAUTION! ⚠
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. Some airflow patterns and some control box
locations are field convertible. Locate the conversion
section of this IOM.
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 will 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.

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). Allow 91 cm clearance for servicing
unit through all access panels.
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.
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 and
the removal or installation of the unit itself.
2. Provide access to hanger brackets, water
valves and fi 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.
12
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.

Drain
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 (waterseal) 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.
⚠ CAUTION! ⚠
CAUTION! Ensure condensate line is pitched toward drain
1/8 inch per ft [11 mm per m] of run.
Duct System Installation - Proper duct sizing and design
is critical to the performance of the unit. The duct system
should be designed to allow adequate and even 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.

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 floor 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
Duct System Design & Installation Guidelines
The following application guidelines must be used
when installing TC units. Failure to follow these guidelines could result in unsatisfactory unit performance
and/or premature failure of some unit components.
ClimateMaster will not warrant, or accept responsibility for products which fail, have defects, damage or insufficient 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.

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.
⚠ 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 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.

Water-Loop Heat Pump Applications
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.
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. In piping systems expected to utilize
water temperatures below 50°F [10°C], 1/2” (13mm)
closed cell insulation is required on all piping surfaces to
eliminate condensation (extended range units required).
Metal to plastic threaded joints should never be used due
to their tendency to leak over time.
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.
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 13 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.
Low Water Temperature Cutout Setting CXM2 When antifreeze is selected, the LT1 jumper (JW3) should
be clipped to select the low temperature (antifreeze 10.0°F
[-12.2°C]) setpoint and avoid nuisance faults (see “Low
Water Temperature Cutout Selection” in this manual). Note:
Low water temperature operation requires extended
range equipment.

Ground-Loop Heat Pump Applications
⚠ CAUTION! ⚠
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.
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 14. 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.
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 manager should
be consulted for the antifreeze best suited to your area.
Low temperature 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 25 to 22°F [-4 to -6°C] and
low temperature 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 CXM2 When antifreeze is selected, the LT1 jumper (JW3) should
be clipped to select the low temperature (antifreeze 10.0°F
[-12.2°C]) setpoint and avoid nuisance faults (see “Low
Water Temperature Cutout Selection” in this manual). Note:
Low water temperature operation requires extended
range equipment.
Earth loop temperatures can range between 25 and
110°F [-4 to 43°C]. Flow rates between 2.25 and 3 gpm
per ton [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.

Ground-Water Heat Pump Applications
Open Loop - Ground Water Systems - Typical open
loop piping is shown in Figure 15. 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.
⚠ 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 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.
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 Requirements - 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
32
use (well water/open loop) and DHW (desuperheater);
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, bladdertype 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 15. 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 18). Note the special wiring diagrams for slow
closing valves (Figures 19 & 20).
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.

Clean water is essential to the performance and life span of water source heat pumps. Contaminants, chemicals, and
minerals all have the potential to cause damage to the water heat heat exchanger if not treated properly. All closed water

Water Quality Requirements, Cont’d.
1. The ClimateMaster Water Quality Table provides
water quality requirements for coaxial & brazed plate
heat exchangers.
2. The water must be evaluated by an independent
testing facility comparing site samples against
this table. When water properties are outside of
these parameters, the water must either be treated
by a professional water treatment specialist to
bring the water quality within the boundaries of
this specification, or an external secondary heat
exchanger must be used to isolate the heat pump
water system from the unsuitable water. Failure to
do so will void the warranty of the heat pump system
and will limit liability for damage caused by leaks or
system failure.
3. Regular sampling, testing and treatment of the water
is necessary to assure that the water quality remains
within acceptable levels thereby allowing the heat
pump to operate at optimum levels.
4. If closed‐loop systems are turned off for extended
periods, water samples must be tested prior to
operating the system.
5. For optimal performance, it is recommended that the
closed‐loop piping systems are initially filled with de‐
ionized water.
6. Well water with chemistry outside of these
boundaries, and salt water or brackish water requires
an external secondary heat exchanger. Surface/Pond
water should not be used.
7. If water temperature is expected to fall below 40°F,
antifreeze is required. Refer to the heat pump IOM for
the correct solution ratios to prevent freezing.

Hydrogen Sulfide has an odor of rotten eggs. If one
detects this smell, a test for H2S must be performed.
If H2S is detected above the limit indicated,
remediation is necessary (Consult with your Water
Testing/Treatment Professional) or a secondary heat
exchanger is required using appropriate materials as
recommended by the heat exchanger supplier.
Suspended solids and particulates must be filtered
to prevent fouling and failure of heat exchangers.
Strainers or particulate filters must be installed to
provide a maximum particle size of 600 micron (0.60
mm, 0.023 in.) using a 20 to 30 mesh screen size.
When a loop is installed in areas with fine material
such as sand or clay, further filtration is required to a
maximum of 100 micron. Refer to the Strainer / Filter
Sizing Chart to capture the particle sizes encountered
on the site.
An electrical grounding system using a dedicated
ground rod meeting NEC and Local Electrical
codes must be installed. Building Ground must not
be connected the WSHP piping system or other
plumbing pipes.
Refer to IOM for instructions on measuring resistance
and leakage currents within water loops.
Do not use PVC pipe for water loop (compressor POE
oil and glycols damage PVC) use of HDPE pipe is
recommended.

OHM meter
Measure the earth ground bond using an Ohm meter between the building's ground rod and the steel well casing.
The resistance measured should be zero Ohms. The NEC allows a resistance to ground up to 20 Ohms. Any
resistance above zero, indicates a poor earth ground which may be the result of a hot neutral line or that
conduc�ve water is present. Both of these may lead to electrolysis and corrosion of the heat pump piping. A check
for both should be performed and resolved.
Note if the well casing is plas�c, a conduc�ve path can be achieved by inser�ng a #6 AWG bare copper wire into the
well water. Remove the temporary conductor when finished.

Electrical - Power Wiring
⚠ WARNING! ⚠
⚠ CAUTION! ⚠
ELECTRICAL - LOW VOLTAGE WIRING
WARNING! Disconnect electrical power source to prevent
injury or death from electrical shock.
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 power block as shown in Figure 11. Consult
electrical data tables for correct fuse size.
Transformer - All 208/230 voltage units are factory wired
for 380 volt. If supply voltage is 420 volt, installer must
rewire transformer. See wire diagram for connections.
Figure 11: TCH 072-120 Line Voltage Wiring
Thermostat Connections - The thermostat should be
wired directly to the CXM2 or DXM2.5 board. Figure 17
shows wiring for TC units. See “Electrical – Thermostat”
(Figure 21) for specific terminal connections. Review
the appropriate AOM (Application, Operation and
Maintenance) manual for units with DDC controls.
Low Water Temperature Cutout Selection - The CXM2/
DXM2.5 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 LT1. Note that the LT1
thermistor is located on the refrigerant line between the
coaxial heat exchanger and expansion device (TXV or cap
tube). Therefore, LT1 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 -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 13 to change the setting
to -12.2°C refrigerant temperature, a more suitable
temperature when using an antifreeze solution. All
ClimateMaster units operating with entering water
temperatures below 15°C must include the optional
water/refrigerant circuit insulation package to prevent
internal condensation.

compressor contactor coil has been provided on the
CXM2/DXM2.5 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 the specific unit wiring
diagram for details.

CAUTION! Many units are installed with a factory or field
supplied manual or electric shut-off valve. DAMAGE WILL
OCCUR if shut-off valve is closed during unit operation. A
high pressure switch must be installed on the heat pump side
of any field provided shut-off valves and connected to the
heat pump controls in series with the built-in refrigerant circuit
high pressure switch to disable compressor operation if water
pressure exceeds pressure switch setting. The field installed
high pressure switch shall have a cut-out pressure of 300
psig and a cut-in pressure of 250 psig. This pressure switch
can be ordered from ClimateMaster with a 1/4” internal flare
connection as part number 39B0005N02.
Thermostat
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 14 shows typical wiring for a 24VAC
external solenoid valve. This wiring should only be used
if valve fully opens in 15 second. Figure 20 illustrates
a typical slow closing water control valve wiring for
Belimo 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.
Note: This valve can overheat the anticipator of an
electromechanical thermostat. Therefore, only relay or
triac based thermostats should be used.

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. Wire the
appropriate thermostat as shown in Figure 20 to the
low voltage terminal strip on the CXM2 or DXM2.5
control board. Practically any heat pump thermostat
will work with ClimateMaster units, provided it has
the correct number of heating and cooling stages.

Blower Adjustment
⚠ CAUTION! ⚠
CAUTION! Always disconnect all power supply(s) to unit
prior to making belt or sheave adjustments. Inadvertently
starting of the motor can cause damage to the equipment
and personal injury.
Airflow and External Static Pressure Selection
Adjustment - The TC_L Series is available with standard,
low, and high static options. These options will substitute
a different blower drive sheave for each static range.
In addition certain static ranges (bold print in Tables 5a
through 5k) may require the optional large fan motor.
Please specify static range and motor horsepower when
ordering. See model nomenclature.
Sheave Adjustment - The TC_L Series is supplied
with variable sheave drive on the fan motor to adjust
for differing airflows at various ESP conditions. Select
an airflow requirement on the left side of the table, then
move horizontally to right under the required ESP. Note
the sheave turns open, rpm and horsepower for that
condition. Fully closed the sheave will produce the
highest static capability (higher rpm). To adjust sheave
position: loosen belt tension and remove belt, loosen set
screw on variable sheave (on fan motor) and open sheave
to desired position. Retighten set screw and replace belt
and set belt tension as below.
Belt Tensioning - An overly loose belt will, upon motor
start, produce a slippage 'squeel' and cause premature
belt failure and or intermittent airflow. An overly tight belt
can cause premature motor or blower bearing failure.
Belt Tensioning Procedure - TC_L
1. Remove belt from motor sheave
2. Lift motor assembly
3. Loosen the 5/16" hex nuts on the grommet motor
adjustment bolts (2 per bolt). To increase the belt
tension loosen the top hex nut. To decrease the belt
tension loosen the bottom hex nut.
4. Turn the bolts by hand to the desired position then
tighten the 5/16" hex nuts ( 2 per bolt).
5. Lower the motor assembly
6. Install the belt
7. The belt should be tensioned tensioning gauge method
such as the Browning Belt Tensioner to set proper belt
tension (See next page).
Notes:
- Motor position should not need adjustment.
- Motor sheave position is at mid position of each sheave. Thus the motor sheave is typically 2.5 turns open on a 5 turn sheave.
Sheave and Pulley Alignment - Verify belt is straight;
misalignment will cause premature belt failure. Adjust
sheave if needed.

General Rules of Tensioning
DEFLECTION =
BELT SPAN
64
BELT SP
1. Ideal tension is the lowest tension at which the belt will
not slip under peak load conditions.
2. Check tension frequently during the first 24-48 hours
of operation.
3. Over tensioning shortens belt and bearing life.
4. Keep belts free from foreign material which may
cause slip.
5. Make V-drive inspection on periodic basis. Tension
when slipping. Never apply belt dressing as this will
damage the belt and cause early failure.
AN
Tension Measurement Procedure
FORCE
SCALE
SPAN
SCALE
Belt Deflection Force

LARGE
“O” RING
Measure the belt span (see sketch).
Position bottom of the large “O” ring on the span scale at the measured belt span.
Set the small “O” ring on the deflection force scale to zero.
Place the tension checker squarely on one belt at the center of the belt span. Apply a
force on the plunger and perpendicular to the belt span until the bottom of the large
“O” ring is even with the top of the next belt or with the bottom of a straight edge laid
across the sheaves.
5. Remove the tension checker and read the forct applied from the bottom of the small
“O” ring on the deflection force scale.
6. Compare the force you have applied with the values given in the table below. The force
should be between the minimum and maximum shown. The maximum value is shown
for “New Belt” and new belts should be tensioned at this value to allow for expected
tension loss. Used belts should be maintained at the minimum value as indicated in the
table below.
NOTE: The ratio of deflection to belt span is 1:64.

Unit Starting and Operating Limits
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 4 for
operating limits.
Commissioning Limits
Starting conditions are based upon the following notes:
Notes:
1. Limits in Table 5 are not normal or continuous
operating limits. Minimum/maximum limits are startup limits to bring the building space up to occupancy
temperatures. Units are not designed to operate
under these limits on a regular basis.
2. Voltage utilization range complies with AHRI
Standard 110.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
Tranquility ® Compact Belt Drive ( TC _L) Series
Rev.:24 Januar y, 2023
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. 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.
Models with Waterside Economizer also manually
open economizer valve and coil air vents (2) to bleed
air from coil.
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 86°F [30°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.
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.

⚠ 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 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.

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. Commercial
380-420V units are factory wired for 380V operation
unless specified otherwise.
Balancing/shutoff valves: Ensure that all isolation
valves are open (after system flushing - see System
Checkout) and water control valves are wired.
Entering water and air: Ensure that entering water
and air temperatures are within operating limits of
Table 9.
Low water temperature cutout: Verify that low water
temperature cut-out on the CXM2/DXM2.5 control is
properly set.
Unit blower wheel: Manually rotate blower wheel to
verify free rotation and ensure that all blower wheels
are secured to the blower motor shaft and centered in
housing.
Blower motor: Verify motor bolts are tight. DO NOT
oil motors upon start-up. Fan motors are pre-oiled at
the factory.
Check shaft pillow blocks, sheave and pulley are tight
Verify sheave has been set to turns in design
requirement. Record turns on start up log sheet.
Verify belt is straight and proper tension
Condensate line: Verify that condensate line is open,
trapped, vented 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 CXM2 or DXM2.5 field
selection options are properly set.

System water temperature: Check water temperature
for proper range and also verify heating and cooling
setpoints 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 fl ow 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.

THE SMART SOLUTION FOR ENERGY EFFICIENCY
Tranquility ® Compact Belt Drive ( TC _L) Series

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 9. 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.
c. Note: Units have a five minute time delay in
the control circuit that can be eliminated on the
CXM2/DXM2.5 control board as shown below in
Figure 22. See controls description for details.
d. 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 tables 10a through 10e.
e. 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. Check the
temperature of both entering and leaving water.
If temperature is within range table, proceed
with the test. If temperature is outside of the
operating range, check refrigerant pressures and
compare to tables 12 through 15. Verify correct
water flow by comparing unit pressure drop
across the heat exchanger versus the data in
tables 10a through 10e. 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 tables 8a
through 8e. 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
6.

9.
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.
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 17. 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
tables 11 through 16. Verify correct water flow
by comparing unit pressure drop across the heat
exchanger versus the data in tables 10a through
10e. 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 (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
tables 10a through 10e.
e. In S-I units, 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.
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.
When testing is complete, set system to maintain
desired comfort level.
BE CERTAIN TO FILL OUT AND FORWARD
ALL WARRANTY REGISTRATION PAPERS TO
CLIMATEMASTER.
Note: If performance during any mode appears
abnormal, refer to the CXM2/DXM2.5 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.

THE SMART SOLUTION FOR ENERGY EFFICIENCY

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.
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.
Belt - Check that the belt is tight. Retighten if needed.
Replace if it is split or cracked.
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.
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.
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.

exclude CM’s liability for death, personal injury or fraud.
LIMITATION OF REMEDIES
In the event of a breach of this Limited Express Warranty or any warranty that is mandatory under applicable imperative law, CM will only be obligated at CM’s option to either 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, U.S.A. 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. TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, THIS REMEDY IS THE SOLE AND EXCLUSIVE REMEDY OF THE CUSTOMER 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. If, notwithstanding the disclaimers contained herein, it is determined by a court or other qualied judicial body that other warranties exist, any such warranty, including
without limitation any express warranty or any implied warranty of tness for particular purpose and merchantability, shall be limited to the duration of the Limited Express Warranty. This Limited Express Warranty does not exclude any warranty that is
mandatory and that may not be excluded under applicable imperative law.
