Inspection
Upon receipt of the equipment, carefully check the
shipment against the bill of lading. Make sure all units
have been received. Inspect the carton or crating of
each unit, and inspect each unit for damage. Assure
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 the ClimateMaster Traffic Department 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. Do not stack TMW170 or 340. The stack limit for
TMW036, 060 and 120 is three.
Unit Protection
Cover units on the job site with either shipping
packaging, vinyl film, 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.
CAUTION!
CAUTION! All three phase scroll compressors must have
direction of rotation verified at start-up. Verification is
achieved by checking compressor Amp draw. Amp draw
will be substantially lower compared to nameplate values.
Additionally, reverse rotation results in an elevated sound
level compared to correct rotation. Reverse rotation will
result in compressor internal overload trip within several
minutes. Verify compressor type before proceeding.
CAUTION!
CAUTION! DO NOT store or install units in corrosive
environments or in locations subject to temperature or
humidity extremes (e.g., attics, garages, rooftops, etc.).
Corrosive conditions and high temperature or humidity can
significantly reduce performance, reliability, and service life.
Always move and store units in an upright position. Tilting
units on their sides may cause equipment damage.
CAUTION!
CAUTION! CUT HAZARD - Failure to follow this caution
may result in personal injury. Sheet metal parts may have
sharp edges or burrs. Use care and wear appropriate
protective clothing, safety glasses and gloves when
handling parts and servicing heat pumps.
Examine all pipes, fittings, and valves before installing
any of the system components. Remove any dirt or trash
found in or on these components.
Pre-Installation
Installation, Operation, and Maintenance instructions
are provided with each unit.. The installation site chosen
should include adequate service clearance around the
unit. Before unit start-up, read all manuals and become
familiar with the unit and its operation. Thoroughly check
the system before operation.
Prepare units for installation as follows:
1. Compare the electrical data on the unit nameplate
with ordering and shipping information to verify that
the correct unit has been shipped.
2. Keep the cabinet covered with the shipping
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.

Unit Installation
TMW Unit Location
These 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.
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.
Locate the unit in an indoor area that allows easy
removal of access panels, and has enough space for
service personnel to perform maintenance or repair.
Provide sufficient room to make water and electrical
connections.. Any access panel screws that would be
difficult to remove after the unit is installed should be
removed prior to setting the unit. These units are not
approved for outdoor installation and, therefore, must
be installed inside the structure being conditioned. Do
not locate in areas where ambient conditions are not
maintained within 4-38°C.
WARNING!
WARNING! Do not bend or kink supply lines or hoses.
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. 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 and causes a slight kink.
Insulation is not required on loop water piping
except where the piping runs through unheated
areas or outside the building or when the loop water
temperature is below the minimum expected dew
point of the pipe ambient temperature. Insulation is
required if loop water temperature drops below the
dew point.
Pipe joint compound is not necessary when Teflon
threaded tape is pre-applied to hose assemblies or
when flared-end connections are used. If pipe joint
compound is preferred, use compound only in small
amounts on the pipe threads of the fitting adapters.
Prevent sealant from reaching the flared surfaces of
the joint.
Note: When antifreeze is used in the loop, assure
that it is compatible with Teflon tape or pipe joint
compound employed.
WARNING!
WARNING! Piping must comply with all applicable codes.
Maximum allowable torque for brass fittings is
41 N-m. If a torque wrench is not available, tighten
finger-tight plus one quarter turn. Tighten steel
fittings as necessary.

Piping 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.
Optional pressure-rated hose assemblies designed
specifically for use with ClimateMaster units are available.
Similar hoses can be obtained from alternate suppliers.
Supply and return hoses are fitted with swivel-joint fittings
at one end to prevent kinking during installation.
Refer to Figure 1 for an illustration of a Supply/Return
Hose Kit. Male adapters secure hose assemblies to the
unit and risers. Install hose assemblies properly and
check them regularly to avoid system failure and reduced
service life.
CAUTION!
CAUTION! Corrosive system water requires corrosion
resistant fittings and hoses and possibly water treatment.

LOAD PLUMBING INSTALLATION
TMW Unit Load Plumbing
The applications are too varied to describe in this
document. However, some basic guidelines will be
presented. Much of the discussions on water loop
applications would be valid for the load plumbing
discussion as well. All plumbing should conform to local
codes with the following considerations:
Wide temperature variation applications such as
heating/cooling coils:
- Employ piping materials that are rated for the
maximum temperature and pressure combination.
This excludes PVC for most heating applications.
- Insure that load water flow in high temperature
heating applications is at least 3.2 l/m per kW
to improve performance and reduce nuisance high
pressure faults.
- DO NOT employ plastic to metal threaded joints
- Utilize a pressure tank and air separator vent system
to equalize pressure and remove air..
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.
Swimming Pool Hot Tub Applications:
- Load side heat exchanger should be isolated with
secondary heat exchanger constructed of anticorrosion material in all chlorine/bromine fluid
applications.
Potable Water Applications:
- Load side heat exchanger should be isolated with
secondary heat exchanger for use in potable water
systems.
- Insure load water flow in high temperature heating
applications is at least 3.2 l/m per kW to improve
performance and reduce nuissance to high pressure
faults.

Water-Loop Heat Pump Applications
Commercial systems typically include a number of
units plumbed 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 10°C, 13mm closed cell insulation is required on
all piping surfaces to eliminate condensation. Metal to
plastic threaded joints should never be employed due
to their tendency to leak over time. Teflon tape thread
sealant is recommended for FPT water connections
(commercial class) to minimize internal fouling of the heat
exchanger. Do not overtighten connections and route
piping so as not to interfere with service or maintenance
access. Hose kits are available from ClimateMaster in
Figure 2 for connection between the TMW unit and the
piping system. The hose kits include shut off valves, P/T
plugs for performance measurement, high pressure
stainless steel braid hose, "Y" type strainer 20 mesh
(841 micron) [0.84mm]) with blowdown valve, and "J"
type swivel connection. Balancing valves to facilitate
the balancing of the system, may also be included in
the hose kit. The piping system should be flushed to
remove dirt, piping chips, and other foreign material
prior to operation. See Piping System Cleaning and
Flushing Procedures later in this document. The flow
rate is usually set between 2.4 l/m and 3.2 l/m per kW
of cooling capacity. ClimateMaster recommends 2.7
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 flow
verification, as well as performance checks.
Load Connections
(Hot Water/Chilled Water)
Source Connections
Power Disconnect
Cooling Tower/Boiler Systems typically utilize a
common loop maintained between 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.
Low Water Temperature Cutout Setting
CXM or DXM Control: When an antifreeze is selected,
the FP1 jumper (JW3) should be clipped to select the
low temperature 12°C setpoint to avoid nuisance faults.
See Figure 4: Low Water Temperature Cutout - FP1.

Ground-Water Heat Pump Applications
Typical open loop piping is shown in Figure 3. Shut off valves
should be included in case of servicing. Boiler drains or other
valves should be ‘tee’d’ into the line to allow acid flushing of
just the heat exchanger. Pressure temperature plugs should
be used so that flow 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 1 for water quality guidelines. The unit can
be ordered with either a copper or cupro-nickel water heat
exchanger. 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,
a closed loop system is recommended. It is recommended
to install an intermediate heat exchanger to isolate an open
loop from the heat pump loop on open well systems. Heat
exchangers may over time lose heat exchange capabilities
due to a build up of mineral deposits inside. These can be
cleaned only by a qualified service mechanic as acid and
special pumping equipment are required.

The ClimateMaster Water Quality Table provides water quality requirements for ClimateMaster coaxial heat exchangers. The water should be evaluated by an
independent testing facility comparing to this Table and when properties are outside of these requirements, an external secondary heat exchanger must be used to
isolate the heat pump heat exchanger from the unsuitable water. Failure to do so will void the warranty for the coaxial heat exchanger and any other components
damaged by a leak.
Notes:
• Closed Recirculating system is identified by a closed pressurized piping system.
• Recirculating open wells should observe the open recirculating design considerations.
• NR - Application not recommended.
• "-" No design Maximum.

Ground-Water Heat Pump Applications
In areas with extremely hard water, the owner should
be informed that the heat exchanger may require
occasional acid flushing.
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 handle at least one minute run
time of the pump to prevent premature pump failure
using its drawdown capacity rating. Discharge water
from the unit is not contaminated in any manner and
can be disposed of in various ways depending on local
building codes; i.e. 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.
Low Water Temperature Cut-Out Setting
For all open loop systems the -1°C FP1 setting (factory
setting-water) should be used to avoid freeze damage
to the unit. See Figure 4: “Low Water Temperature
Cutout - FP1”.
WARNING!
WARNING! Never jumper terminal “A” from CXM or DXM
board #1 to CXM or DXM board #2 on multi-compressor/
control bound units. See Figure 5 in electrical section of this
document for motorized valve wiring.
NOTICE! Low temperature limit system will not
allow leaving load water temperature (cooling
mode) or leaving source water temperature (heating
mode) to be below 5.6°C.
Water Control Valve
Note the placement of the water control valve. Always
maintain water pressure in the heat exchanger by
placing water control valves at the outlet of the unit to
prevent mineral precipitation. Pilot operated or Taco
slow closing valve’s solenoid 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 the Taco slow closing valve
can draw up to 35VA. This can overload smaller 40 or
50 VA transformers depending on the other controls
employed. A typical pilot operated solenoid valve
draws approximately 15VA.
Flow Regulation
Flow regulation can be accomplished by two methods.
First, most water control valves have a built in flow
adjustment. By measuring the pressure drop through
the unit heat exchanger, flow rate can be determined
and compared to Tables 7 and 8. Since the pressure
is constantly varying, two pressure gauges might be
needed. Simply adjust the water control valve until the
desired flow of 1.6 l/m and 2.2 l/m per kW is achieved.
Secondly, a flow control device may be installed. The
devices are typically an orifice of plastic material that
is designed to allow a specified flow rate. These are
mounted on the outlet of the water control valve. On
occasion, these valves can produce a velocity noise
that can be reduced by applying some back pressure.
This is accomplished by slightly closing the leaving
isolation valve of the ground water setup.

Ground-Loop Heat Pump Applications
CAUTION!
CAUTION! The following instructions represent industry
accepted installation practices for Closed Loop Earth
Coupled Heat Pump Systems. They are provided to assist
the contractor in installing trouble free ground loops. These
instructions are recommendations only. State 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.
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.
to their tendency to corrode. All plastic to metal threaded
fittings should be avoided due to their potential to leak in
earth coupled applications and a flanged fitting substituted.
P/T plugs should be used so that flow can be measured
using the pressure drop of the unit heat exchanger in lieu of
other flow measurement means. Earth loop temperatures
can range between -4 to 43°C, and 2.4 l/m to 3.2 l/m per kW
of cooling capacity is recommended in these applications.
Upon completion of the ground loop piping, pressure test
the loop to assure a leak free system. Horizontal Systems: Test
individual loops as installed. Test entire system when all loops
are assembled. Vertical U-Bends and Pond Loop Systems:
Test Vertical U-bends and pond loop assemblies prior to
installation with a test pressure of at least 689 kPa.
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. Flush the loop first with the unit isolated to avoid
flushing debris from the loop into the unit heat exchanger.
Piping Installation
All earth loop piping materials should be limited to only
polyethylene fusion for inground sections of the loop.
Galvanized or steel fitting should not be used at any time due

Antifreeze
In areas where minimum entering loop temperatures
drop below 5°C or where piping will be routed through
areas subject to freezing, anti-freeze is needed. Alcohols
and glycols are commonly used as antifreezes, however
your local sales manager should be consulted for the
antifreeze best suited to your area. Freeze protection
should be maintained to 9°C below the lowest expected
entering loop temperature. For example, if -1°C is the
minimum expected entering loop temperature, the
leaving loop temperature would be -4 to -6°C and
freeze protection should be at -10°C e.g. -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 water level to prevent fuming.
Initially 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. Antifreeze
concentration should be checked from a well mixed
sample using a hydrometer to measure specific gravity.
14
Low Water Temperature Cut-Out Setting
CXM or DXM Control:
When an antifreeze is selected, the FP1 jumper [JW3]
should be clipped to select the low temperature
12.2°C setpoint to avoid nuisance faults. See Figure 4.

CXM Controls
CXM Control
For detailed control information, see the CXM
Application, Operation and Maintenance (AOM)
manual (part #97B0003N12).
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.
Field Selectable Inputs
Test mode: Test mode allows the service technician to
check the operation of the control in a timely manner. By
momentarily shorting the test terminals, the CXM control
enters a 20 minute test mode period in which all time
delays are sped up 15 times. Upon entering test mode,
the status LED will flash a code representing the last
fault. For diagnostic ease at the thermostat, the alarm
relay will also cycle during test mode. The alarm relay
will cycle on and off similar to the status LED to indicate
a code representing the last fault, at the thermostat. Test
mode can be exited by shorting the test terminals for 3
seconds.
Retry Mode: If the control is attempting a retry of a
fault, the status LED will slow flash (slow flash = one
flash every 2 seconds) to indicate the control is in the
process of retrying.
On = Stage 1. Off = Stage 2
Field Configuration Options
Note: In the following field configuration options,
jumper wires should be clipped ONLY when power is
removed from the CXM control.
Table 3a: CXM/DXM LED and Alarm Relay Operations
Source coil low temperature limit setting: Jumper
3 (JW3-FP1 Low Temp) provides field selection of
temperature limit setting for FP1 of -1°C or -12.2°C
(refrigerant temperature).
Not Clipped = -1°C. Clipped = -12.2°C.
Load coil low temperature limit setting: Jumper
2 (JW2-FP2 Low Temp) provides field selection of
temperature limit setting for FP2 of -1°C or -12.2°C
(refrigerant temperature). Note: This jumper should
only be clipped under extenuating circumstances, as
recommended by the factory.
Not Clipped = -1°C. Clipped = -12.2°C.
Alarm relay setting: Jumper 1 (JW1-AL2 Dry) provides
field selection of the alarm relay terminal AL2 to
be jumpered to 24VAC or to be a dry contact (no
connection).
Not Clipped = AL2 connected to R. Clipped = AL2 dry
contact (no connection).
DIP 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 field configuration 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 field 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.
Source coil low temperature limit setting: Jumper
3 (JW3-FP1 Low Temp) provides field selection of
temperature limit setting for FP1 of -1°C or -12.2°C
(refrigerant temperature).
Not Clipped = -1°C. Clipped = -12.2°C.

1.3 - Thermostat type (heat pump or heat/cool): DIP
1.3 provides selection of thermostat type. Heat pump
or heat/cool thermostats can be selected. When in
heat/cool mode, Y1 is the input call for cooling stage
1; Y2 is the input call for cooling stage 2; W1 is the
input call for heating stage 1; and O/W2 is the input
call for heating stage 2. In heat pump mode, Y1 is the
input call for compressor stage 1; Y2 is the input call
for compressor stage 2; W1 is the input call for heating
stage 3 or emergency heat; and O/W2 is the input
call for reversing valve (heating or cooling, depending
upon DIP 1.4). On = Heat Pump. Off = Heat/Cool.
1.4 - Thermostat type (O/B): DIP 1.4 provides selection
of thermostat type for reversing valve activation. Heat
pump thermostats with “O” output (reversing valve
energized for cooling) or “B” output (reversing valve
energized for heating) can be selected with DIP 1.4.
On = HP stat with “O” output for cooling. Off = HP stat
with “B” output for heating.
1.5 - Dehumidification mode: DIP 1.5 provides
selection of normal or dehumidification fan mode. In
dehumidification mode, the fan speed relay will remain
off during cooling stage 2. In normal mode, the fan
speed relay will turn on during cooling stage 2.
On = Normal fan mode. Off = Dehumidification mode.
1.6 - DDC output at EH2: DIP 1.6 provides selection
for DDC operation. If set to “DDC Output at EH2,”
the EH2 terminal will continuously output the last fault
code of the controller. If set to “EH2 normal,” EH2 will
operate as standard electric heat output.
On = EH2 Normal. Off = DDC Output at EH2.
1.7 - Boilerless operation: DIP 1.7 provides selection
of boilerless operation. In boilerless mode, the
compressor is only used for heating when FP1 is above
the temperature specified by the setting of DIP 1.8.
Below DIP 1.8 setting, the compressor is not used and
the control goes into emergency heat mode, staging
on EH1 and EH2 to provide heating.
2.2 - Accessory1 relay personality: DIP 2.2 provides
selection of ACC 1 relay personality (relay operation/
characteristics). See table 6c for description of
functionality.
2.3 - Accessory1 relay personality: DIP 2.3 provides
selection of ACC 1 relay options. See table 6c for
description of functionality.
2.4 - Accessory2 relay personality: DIP 2.4 provides
selection of ACC 2 relay personality (relay operation/
characteristics). See table 6c for description of

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 flashing to signal that the control is trying to
recover from a fault input. The control will stage off the
outputs and then “try again” to satisfy the thermostat
input call. Once the thermostat input call is satisfied,
the control will continue on as if no fault occurred.
If 3 consecutive faults occur without satisfying the
thermostat input call, the control will go into “lockout”
mode. The last fault causing the lockout will be stored
in memory and can be viewed at the “fault” LED (DXM
board) or by going into test mode (CXM board). Note:
FP1/FP2 faults are factory set at only one try.
Lockout: In lockout mode, the status LED will begin
fast flashing. The compressor relay is turned off
immediately. Lockout mode can be “soft” reset by
turning off the thermostat (or satisfying the call). A
“soft” reset keeps the fault in memory but resets the
control. A “hard” reset (disconnecting power to the
control) resets the control and erases fault memory.
Lockout with emergency heat: While in lockout mode,
if W becomes active (CXM), emergency heat mode will
occur. If DXM is configured for heat pump thermostat
type (DIP 1.3), emergency heat will become active if O/
W2 is energized.
High pressure switch: When the high pressure switch
opens due to high refrigerant pressures, the compressor
relay is de-energized immediately since the high pressure
switch is in series with the compressor contactor coil. The
high pressure fault recognition is immediate (does not
delay for 30 continuous seconds before de-energizing the
compressor).
High pressure lockout code = 2
Example: 2 quick flashes, 10 sec pause, 2 quick flashes,
10 sec. pause, etc.
Low pressure switch: The low pressure switch must be
open and remain open for 30 continuous seconds during
“on” cycle to be recognized as a low pressure fault. If
the low pressure switch is open for 30 seconds prior to
compressor power up it will be considered a low pressure
(loss of charge) fault. The low pressure switch input is
bypassed for the initial 120 seconds of a compressor run
cycle.
Source 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 120
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
Load 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 overflow: The condensate overflow sensor
must sense overflow level for 30 continuous seconds to
be recognized as a CO fault. Condensate overflow will
be monitored at all times.
CO lockout code = 6
Over/under voltage shutdown: An over/under voltage
condition exists when the control voltage is outside the
range of 19VAC to 30VAC. Over/under voltage shut
down is a self-resetting safety. If the voltage comes
back within range for at least 0.5 seconds, normal
operation is restored. This is not considered a fault
or lockout. If the CXM/DXM is in over/under voltage
shutdown for 15 minutes, the alarm relay will close.
Over/under voltage shut down code = 7
Unit Performance Sentinel-UPS (patent pending): The
UPS feature indicates when the heat pump is operating
inefficiently. A UPS condition exists when:
a) In heating mode with compressor energized, FP2 is
greater than 52°C for 30 continuous seconds, or:
b) In cooling mode with compressor energized, FP1 is
greater than 52°C for 30 continuous seconds, or:
c) In cooling mode with compressor energized, FP2 is
less than 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
Low pressure lockout code = 3

Safety Features
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.
Unit Commissioning & Operating Conditions
Environment – This unit is designed for indoor
installation only. Do not install in an area subject to
freezing or where humidity levels can cause cabinet
condensation.
Power Supply – A voltage variation of +/- 10% of
nameplate utilization voltage is acceptable.
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 flash code 3 when the unit is in ESD mode.
ESD mode = code 3 (green “status” LED)
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 flash Code 1 (when in test mode).
The green status LED and red fault LED on the DXM
board advise the technician of the current status of the
DXM control. The status LED will indicate the current
mode that the DXM control is in. The fault LED will
ALWAYS flash a code representing the LAST fault in
memory. If there is no fault in memory, the fault LED will
flash Code 1. The yellow test LED will turn on when in
test mode.
CXM/DXM Control Start-up Operation
The control will not operate until all inputs and safety
controls are checked for normal conditions. The
compressor will have a 5 minute anti-short cycle delay
at power-up. The first time after power-up that there is
a call for compressor, the compressor will follow a 5 to
80 second random start delay. After the random start
delay and anti-short cycle delay, the compressor relay
will be energized. On all subsequent compressor calls,
the random start delay is omitted.
Operation and performance is primarily dependent
upon water temperatures, water flow rates and
ambient air temperature. This water to water
heat pump is capable of operating over a wide
temperature range and with flow rates of between
1.5 GPM (.1 l/s) and 3 GPM (.19 l/s) per ton, however
usually no more than one of these factors may be at a
minimum or maximum level at a time.
The commissioning table indicates water and
air temperatures which are suitable for initial unit
commissioning in an environment where the flow rate
and water temperature is not yet stable and to avoid
nuisance shut down of the units freeze and refrigerant
pressure safeties.
The operating table indicates the maximum and
minimum temperature ranges of the unit.

Piping System Cleaning & Flushing
Cleaning and flushing of 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. Verify electrical power to the unit is disconnected.
2. Install the system with the supply hose connected
directly to the return riser valve. Use a single length
of flexible hose.
3. Open all air vents. Fill the system with the water.
DO NOT allow system to overflow. Bleed all air from
the system. Pressurize and check the system for
leaks and repair appropriately.
4. Verify all strainers are in place. Start the pumps, and
systematically check each vent to ensure all air is
bled from the system.
5. Verify make-up water is available. Adjust make-up
water appropriately 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 29°C. Open the 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 .5 kg
per 750 L of water (or other equivalent approved
cleaning agent). Reset the boiler to raise the loop
temperature to about 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 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 slightly alkaline (pH 6-8.5). Add
chemicals, as appropriate, to maintain acidity levels.
10. When the system is successfully cleaned, flushed,
refilled and bled, check the main system panels,
safety cutouts and alarms. Set the controls to
properly maintain loop temperatures.

CAUTION!
CAUTION! To avoid possible damage to a plastic (PVC)
piping system, do not allow temperatures to exceed 43°C.
CAUTION!
CAUTION! DO NOT use 'stop leak' or any similar chemical
agent in this system. Addition of these chemicals to the
loop water will foul the system and inhibit unit operation.

Unit & System Checkout
BEFORE POWERING SYSTEM, please check the following:
WARNING!
WARNING! Verify ALL water controls are open and allow
water flow prior to engaging the compressor. Freezing of
the coax or water lines can permanently damage the heat
pump.
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.
UNIT CHECKOUT
❑
Balancing/Shutoff Valves: Ensure all isolation
valves are open, water control valves wired and
open or coax may freeze and burst.
❑
Line Voltage and Wiring: Ensure Voltage is
within an acceptable range for the unit and
wiring and fuses/breakers are properly sized.
Low voltage wiring is complete.
❑
Transformer On dual voltage units, the installer
must confirm that the power supply and unit
transformer wiring match. Installer must rewire
as needed. Refer to the unit wiring diagram for
proper connections.
❑
Entering Water: Ensure entering water
temperatures are within operating limits of Table 6.
❑
Low Water Temperature Cutout: Verify low
water temperature cut-out on CXM/DXM is

❑
Water Flow Balancing: Verify inlet and outlet
water temperatures on both Load and source
are recorded for each heat pump upon
startup. This check can eliminate nuisance
trip outs and high velocity water flows that
can erode heat exchangers.
❑
Unit Controls: Verify CXM or DXM field
selection options are proper and complete.
SYSTEM CHECKOUT
❑
System Water Temperature: Check load and
source water temperature for proper range and
also verify heating and cooling setpoints for
proper operation.
❑
System pH: System water pH is 6 - 8.5. Proper
pH promotes longevity of hoses and fittings.
❑
System Flushing: Verify all hoses are connected
end to end when flushing to ensure debris
bypasses unit heat exchanger and water valves
etc. Water used in the system must be potable
quality initially and clean of dirt, piping slag,
and strong chemical cleaning agents. Verify 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 the standby pump is
properly installed and in operating condition.
❑
System Controls: Verify system controls
function and operate in the proper sequence.
❑
Low Water Temperature Cutout: Verify
low water temperature cut-out controls are
provided for the outdoor portion of the loop or
operating problems will occur.
❑
System Control Center: Verify control center
and alarm panel for proper setpoints
and operation.
❑
Strainers: Verify 20 mesh (841 micron) [0.84mm]
strainers are installed in load and source water
piping. Confirm maintenance schedule for
strainers.
❑
Miscellaneous: Note any questionable aspects
of the installation.
WARNING!
WARNING! To avoid equipment damage, DO NOT leave

Unit Start Up Procedure
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.
1.
Adjust all valves to their full open position. Turn on
the line power to all heat pump units.
2. Operate each unit in the cooling cycle. Loop water
temperature entering the heat pumps should be
within the limits shown in the operations table.
3. Operate each heat pump in the heating
cycle immediately after checking cooling
cycle operation. A time delay will prevent the
compressor from re-starting for approximately five
(5) minutes.
4. Establish a permanent operating record by logging
the unit operating conditions at initial start-up for
each unit.
5. If a unit fails to operate, conduct the following
checks:
a. Check the voltage and current. They should
comply with the electrical specifications described
on the unit nameplate.
b. Look for wiring errors. Check for loose terminal
screws where wire connections have been made on
both the line and low-voltage terminal boards.
c. Check the supply and return piping. They must
be properly connected to the inlet and outlet
connections on the unit.
d. If the checks described above fail to reveal the
problem and the unit still will not operate, contact
a trained service technician to ensure proper
diagnosis and repair of the equipment.
Note: Units have a five minute time delay in the
control circuit that can be eliminated by entering test
mode. See controls description for detailed features
of the control.

Preventative Maintenance
Heat Exchanger Maintenance –
(Direct Ground Water Applications Only)
If the installation is performed in an area with a known
high mineral content (125 P.P.M. or greater) in the
water, it is best to establish with the owner a periodic
maintenance schedule 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 either the heat exchanger material or
copper water lines. Generally, the more water flowing
through the unit the less chance for scaling therefore
2.7 l/m per kW is recommended as a minimum flow.
Heat Exchanger Maintenance –
(All Other Water Loop Applications)
Generally water coil maintenance is not needed
however, if the installation is located in a system with a
known high dirt or debris content, it is best to establish
with the owner a periodic maintenance schedule so the
coil can be checked regularly. These dirty installations
are a result of the deterioration of iron or galvanized
piping or components in the system or open cooling
towers requiring heavy chemical treatment and
mineral buildup through water use. 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 3.2 l/m per
kW can produce water (or debris) velocities that can
erode the heat exchanger wall and ultimately produce
leaks.
Clean or replace 20 mesh (841 micron) [0.84mm]
strainer/filters on a timely schedule.
Cabinet
Do not allow water to stay in contact with the cabinet
for long periods of time to prevent corrosion of the
cabinet sheet metal. Generally vertical cabinets are
set up from the floor a few inches for prevention. 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 chart for pressure and
temperatures. Verify that air and water flow rates are at
proper levels before servicing the refrigerant circuit.
If the refrigerant circuit is opened for any reason, a new
liquid line filter-drier must be installed.
Compressors
Conduct annual amperage checks to ensure amp draw
is no more than 10% greater than that indicated by
serial plate data.
