General Information
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. Insure that the carrier
makes proper notation of any shortages or damage on all
copies of the freight bill and completes a common carrier
inspection report. Concealed damage not discovered
during unloading must be reported to the carrier within
15 days of receipt of shipment. If not led within 15 days,
the freight company can deny the claim without recourse.
Note: It is the responsibility of the purchaser to le all
necessary claims with the carrier. Notify your equipment
supplier of all damage within fteen (15) days of shipment.
Storage
Equipment should be stored in its original packaging in
a clean, dry area. Store units in an upright position at all
times. 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.

hose into unit. If hose will not connect to your building
drain several options include, relocate end of building
drain, add to or cut hose, use hard plastic or copper
elbow ttings for tight radii (put inside hose). Keep hose
positioned within or over subbase area so hose does not
interfere with front cabinet. Cabinet should not push or
reroute hose. Clamp all joints watertight. Check for leaks.
Internally the drain hose is clamped to drain pan and
pitched correctly. Horizontal runs of condensate hose
should be pitched downward 1/4 inch minimum for every
foot [10mm per 46cm] of hose. Avoid low points because
dirt collects in these areas and may cause blockage. If
blocked the condensate level in drain pan increases.
When the level gets too high, the Console unit has sensor
switch that will shut unit off. Overow may still occur.
If the building drain connection is parallel with oor,
the height can be up to 1-1/2 inches [38mm] above
the subbase for proper pitch and correct drainage. Up
to 5 inches [127mm] above the subbase is allowable,
but drainage will be slower. When the drain connection
is 2-1/2 to 5 inches [64 to 127mm] above, the hose
inside the unit will act as a trap. Heights of more than 5
inches [127mm] above the subbase are NOT allowable
(condensate overow may occur). If the unit has a
disconnect option, drain locations are limited. See unit
conguration pages for details.
Field installation of a trap or vent is not required unless
specied by local codes. Console units are designed
in a blow-through conguration. The condensate drain
pan is located on the outlet side of the blower so that
the pressure in the drain pan is higher than atmospheric
pressures.
When drain connection is completed check for proper
drainage and leaks. Correct if necessary.
If trap is used, check and clean often. See Preventive
Maintenance Instructions.

Installation of Supply and Return Piping
Follow these piping guidelines.
1. Install a drain valve at the base of each supply and
return riser to facilitate system ushing.
2. Install shut-off / balancing valves and unions at each
unit to permit unit removal for servicing.
3. Place strainers at the inlet of each system
circulating pump.
4. Select the proper hose length to allow slack between
connection points. Hoses may vary in length by +2%
to -4% under pressure.
5. Refer to Table 1. Do not exceed the minimum bend
radius for the hose selected. Exceeding the minimum
bend radius may cause the hose to collapse, which
reduces water ow rate. Install an angle adapter to
avoid sharp bends in the hose when the radius falls
below the required minimum.
Insulation is not required on loop water piping except
where the piping runs through unheated areas, outside
the building or when the loop water temperature is
below the minimum expected dew point of the pipe
ambient conditions. Insulation is required if loop water
temperature drops below the dew point (insulation is
required for ground loop applications in most climates).

1-1/4" [31.8mm] 6-3/4" [17.1cm]
CAUTION!
CAUTION! Do not bend or kink supply lines or hoses.
NOTICE! Do not allow hoses to rest against structural
building components. Compressor vibration may be
transmitted through the hoses to the structure, causing
unnecessary noise complaints.
Figure 2: Supply/Return Hose Kit
Pipe joint compound is not necessary when Teon®
thread tape is pre-applied to hose assemblies or when
ared-end connections are used. If pipe joint compound
is preferred, use compound only in small amounts on
the external pipe threads of the tting adapters. Prevent
sealant from reaching the ared surfaces of the joint.
Note: When anti-freeze is used in the loop, insure
that it is compatible with the Teon tape or pipe joint
compound that is applied.
Maximum allowable torque for brass ttings is 30 ft-lbs
[41 N-m]. If a torque wrench is not available, tighten
nger-tight plus one quarter turn. Tighten steel ttings
as necessary.
Optional pressure-rated hose assemblies designed
specically for use with ClimateMaster units are available.
Similar hoses can be obtained from alternate suppliers.
Supply and return hoses are tted with swivel-joint
ttings at one end to prevent kinking during installation.
Refer to Figure 2 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.

CAUTION!
CAUTION! Many units installed with a factory or eld
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 eld 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 eld 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 are
connection as part number 39B0005N02.

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. 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.
Teon 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
congurations 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 ushed to remove dirt,
piping chips, and other foreign material prior to operation
(see “Piping System Cleaning and Flushing Procedures”
in this manual). The ow 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 insure proper maintenance and servicing,
P/T ports are imperative for temperature and ow
verication, 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 ltering will be necessary.
Low Water Temperature Cutout Setting
CXM or DXM Control
When antifreeze is selected, the FP1 jumper (JW3) should
be clipped to select the low temperature (antifreeze 13°F
[-10.6°C]) set point 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!
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
All earth loop piping materials should be limited to
polyethylene fusion only for in-ground sections of the
loop. Galvanized or steel ttings should not be used at
any time due to their tendency to corrode. All plastic to
metal threaded ttings should be avoided due to their
potential to leak in earth coupled applications. A anged
tting should be substituted. P/T plugs should be used
so that ow 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
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 backlling.
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, ush
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 manager should be consulted
for 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
25 to 22°F [-4 to -6°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 uid 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 specic gravity.
Low Water Temperature Cutout Setting
CXM or DXM Control
When antifreeze is selected, the FP1 jumper (JW3) should
be clipped to select the low temperature (antifreeze 13°F
[-10.6°C]) set point and avoid nuisance faults (see “Low
Water Temperature Cutout Selection” in this manual). NOTE:
Low water temperature operation requires extended range
equipment.

Ground-Water Heat Pump Applications
Open Loop - Ground Water Systems
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 ushing of the heat exchanger. Shut
off valves should be positioned to allow ow through
the coax via the boiler drains without allowing ow into
the piping system. P/T plugs should be used so that
pressure drop and temperature can be measured. Piping
materials should be limited to copper or PVC SCH80.
Note: Due to the pressure and temperature extremes,
PVC SCH40 is not recommended.
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 qualied
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 ushing.
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) 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, 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 eld, 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
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. Insure 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..
Flow Regulation
Flow regulation can be accomplished by two methods.
One method of ow 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 ow rate. Since the pressure is
constantly varying, two pressure gauges may be needed.
Adjust the valve until the desired ow of 1.5 to 2 gpm per
ton [2.0 to 2.6 l/m per kW] is achieved. A second method
of ow control requires a ow control device mounted
on the outlet of the water control valve. The device is
typically a brass tting with an orice of rubber or plastic
material that is designed to allow a specied ow rate.
On occasion, ow 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.
CAUTION!
CAUTION! Many units installed with a factory or eld
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 eld provided shut-off valves and connected to the

high pressure switch to disable compressor operation if water
pressure exceeds pressure switch setting. The eld installed

psig and a cut-in pressure of 190 psig. This pressure switch
can be ordered from ClimateMaster with a 1/4” internal are
connection as part number 39B0005N01.
NOTICE! Ground-water applications for commercial
buildings with more than 2-3 units should include a plate
frame heat-exchanger to isolate the heat pumps from the
ground-water and conne heat exchanger cleanings to one
location and lessen maintenance. Direct use of ground-water
may increase the frequency of heat pump maintenance and
may shorten life expectancy.

*Length = Physical distance from thermostat to unit.
Thermostat Installation
The thermostat should be located on an interior wall
in a larger room, away from supply air 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 7 to
the low voltage terminal strip on the CXM or DXM control
board. 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/DXM
Application, Operation and Maintenance (AOM) manual
(part #97B0003N08).
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 ash 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 ash (slow ash = one ash
every 2 seconds) to indicate the control is in the process
of retrying.
Field Conguration Options
Note: In the following eld conguration options, jumper
wires should be clipped ONLY when power is removed
from the CXM control.
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 Switches
Note: In the following eld conguration options, DIP
switches should only be changed when power is removed
from the DXM control.
DIP Package #1 (S1)
DIP Package #1 has 8 switches and provides the
following setup selections:
1.1 - Unit Performance Sentinel (UPS) disable: DIP Switch
1.1 provides eld selection to disable the UPS feature.
On = Enabled. Off = Disabled.
1.2 - Compressor relay staging operation: DIP 1.2
provides selection of compressor relay staging operation.
The compressor relay can be selected to turn on with
a stage 1 or stage 2 call from the thermostat. This is
used with dual stage units (2 compressors where 2 DXM
controls are being used) or with master/slave applications.
In master/slave applications, each compressor and fan will
stage according to its appropriate DIP 1.2 setting. If set
to stage 2, the compressor will have a 3 second on-delay
before energizing during a Stage 2 demand. Also, if set for
stage 2, the alarm relay will NOT cycle during test mode.
On = Stage 1. Off = Stage 2.
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
41

DXM Controls
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 - Dehumidication mode: DIP 1.5 provides
selection of normal or dehumidication fan mode. In
dehumidication 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 = Dehumidication 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 specied 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
set point. Note that the FP1 thermistor is sensing
refrigerant temperature between the coaxial heat
exchanger and the expansion device (TXV or cap tube).
Therefore, the 50°F [10°C] setting is not 50°F [10°C]
water, but approximately 60°F [16°C] EWT.

THE SMART SOLUTION FOR ENERGY EFFICIENCY

Rev.: 30 June, 2008B
Safety Features - CXM/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 ashing 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 satised,
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:
FP1/FP2 faults are factory set at only one try.
Lockout: In lockout mode, the status LED will begin fast
ashing. 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 congured 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 ashes, 10 sec pause, 2 quick ashes,
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 60 seconds of a compressor run
cycle.
Low pressure lockout code = 3
Water coil low temperature (FP1): The FP1 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
FP1 fault. The FP1 input is bypassed for the initial 60
seconds of a compressor run cycle. FP1 is set at the
factory for one try. Therefore, the control will go into
lockout mode once the FP1 fault has occurred.
FP1 lockout code = 4
Air coil low temperature (FP2): The FP2 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
FP2 fault. The FP2 input is bypassed for the initial 60
seconds of a compressor run cycle. FP2 is set at the
factory for one try. Therefore, the control will go into
lockout mode once the FP2 fault has occurred.
FP2 lockout code = 5
Condensate overow: The condensate overow sensor
must sense overow level for 30 continuous seconds to
be recognized as a CO fault. Condensate overow 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

c) In cooling mode with compressor energized, FP2 is
less than 40°F [4.5°C] for 30 continuous seconds.
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 FP1/FP2 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:
a) The compressor is on in the cooling mode and the
FP1 sensor is colder than the FP2 sensor, or:
b) The compressor is on in the heating mode and the
FP2 sensor is colder than the FP1 sensor.
Swapped FP1/FP2 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 ash code 3 when the unit is in ESD mode.
ESD mode = code 3 (green “status” LED)
Do not restart units without inspection and remedy of
faulting condition. Damage may occur.
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 rst 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.
CXM/DXM Controls
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
ash 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 ash a
code representing the LAST fault in memory. If there is
no fault in memory, the fault LED will ash Code 1. The
yellow test LED will turn on when in test mode. CAUTION:

and are based upon the following notes:
Notes:
1. Conditions in Table 8 are not normal or continuous
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 insure
proper unit operation.
Extreme variations in temperature and humidity and/

Piping System Cleaning and Flushing
Piping System Cleaning and Flushing
Cleaning and ushing the WLHP piping system is the
single most important step to insure proper start-up and
continued efcient operation of the system.
Follow the instructions below to properly clean and ush
the system:
1.
Insure 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 exible hose.
3. Open all air vents. Fill the system with water. DO
NOT allow system to overow. 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 make-
up 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. Rell the system and add trisodium phosphate in
a proportion of approximately one pound per 150
gallons [1/2 kg per 750 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. Rell 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, ushed,
relled and bled, check the main system panels,
safety cutouts and alarms. Set the controls to
properly maintain loop temperatures.
CAUTION!
CAUTION! To avoid possible damage to a plastic (PVC)
piping system, do not allow temperatures to exceed 113°F
[45°C].
NOTE:
ClimateMaster strongly recommends all piping
connections, both internal and external to the unit,
be pressure tested for leakage by an appropriate
method prior to any nishing of the interior space
or before access to all connections is limited.
ClimateMaster will not be responsible or liable for
damages from water leaks due to inadequate or a
lack of pressurized leak testing during installation.
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.

Unit and System Checkout
BEFORE POWERING SYSTEM, please check the following:
UNIT CHECKOUT
Balancing/shutoff valves: Insure 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: Insure that transformer
has the properly selected voltage tap. Commercial
208-230V units are factory wired for 208V operation
unless specied otherwise.
Entering water and air: Insure that entering water and
air temperatures are within operating limits of Table 8.
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 insure 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 ow balancing: Record inlet and outlet water
temperatures for each heat pump upon startup. This
check can eliminate nuisance trip outs and high
velocity water ow that could erode heat exchangers.
Unit air coil and lters: Insure that lter is clean and
accessible. Clean air coil of all manufacturing oils.
Unit controls: Verify that CXM or DXM eld selection
options are properly set.
Consoles

Unit and System Checkout Procedure
can cause poor operation or system corrosion.
Cooling tower/boiler: Check equipment for proper set
points 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 set points 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 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 lled 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 springmounted compressors will cause excessive noise, and could
cause component failure due to added vibration.
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 ttings (see Table
3).
System ushing: Verify that all hoses are connected
end to end when ushing to insure 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

Unit Start-Up Procedure
Unit Start-up Procedure
1. Turn the thermostat fan position to “ON”. Blower
should start.
2. Balance air ow 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 8. 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
insure 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 ve minute time delay in the
control circuit that can be eliminated on the CXM/
DXM control board as shown below in Figure 8.
See controls description for details.
c. Check the elevation and cleanliness of the
condensate lines. Dripping may be a sign of a
blocked line. Check that the condensate trap is
lled to provide a water seal.
d.
Refer to Table 9. 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.
e.
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].
f. Turn thermostat to “OFF” position. A hissing noise
indicates proper functioning of the reversing valve.
6. Allow ve (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 9. 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.
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 insure 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.
WARNING!
WARNING! When the disconnect switch is closed, high
voltage is present in some areas of the electrical panel.
Exercise caution when working with energized equipment.
CAUTION!
CAUTION! Verify that ALL water control valves are open and
allow water ow prior to engaging the compressor. Freezing
of the coax or water lines can permanently damage the heat
pump.

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 owing through the unit, the less chance
for scaling. Therefore, 1.5 gpm per ton [2.0 l/m per kW]
is recommended as a minimum ow. Minimum ow rate
for entering water temperatures below 50°F [10°C] is 2.0
gpm per ton [2.6 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
owing through the unit, the less chance for scaling.
However, ow 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 lter.
Washable, high efciency, electrostatic lters, when dirty,
can exhibit a very high pressure drop for the fan motor
and reduce air ow, resulting in poor performance. It is
especially important to provide consistent washing of
these lters (in the opposite direction of the normal air
ow) once per month using a high pressure wash similar
to those found at self-serve car washes.
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 insure indoor air quality. The
condensate drain can pick up lint and dirt, especially
with dirty lters. Inspect the drain twice a year to avoid
the possibility of plugging and eventual overow.
Compressor
Conduct annual amperage checks to insure 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
insure 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 ns 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. 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 ow rates are at
proper levels before servicing the refrigerant circuit.
