General Information
Inspection
Upon receipt of the equipment, carefully check the shipment
against the bill of lading. Make sure all units and accessories
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 filed within 15 days, the freight company can
deny the claim without recourse. Note: It is the responsibility of
the purchaser to file all necessary claims with the carrier. Notify
your equipment supplier of all damage within fifteen (15) days
of shipment.
Storage
Equipment should be stored in its original packaging in a
clean, dry area. Store units in an upright position at all times.
Stack units a maximum of 3 units high.
Unit Protection
Cover units on the job site with either the original packaging
or an equivalent protective covering. Cap the open ends
of pipes stored on the job site. In areas where painting,
plastering, and/or spraying has not been completed, all due
precautions must be taken to avoid physical damage to the
units and contamination by foreign material. Physical damage
and contamination may prevent proper start-up and may
result in costly equipment clean-up.
Examine all pipes, fittings, and valves before installing any of
the system components. Remove any dirt or debris found in
or on these components.
Pre-Installation
Installation, Operation, and Maintenance instructions are
provided with each unit. Horizontal equipment is designed for
installation above false ceiling or in a ceiling plenum. Other
unit configurations are typically installed in a mechanical
room. The installation site chosen should include adequate
service clearance around the unit. Before unit start-up,
read all manuals and become familiar with the unit and its
operation. Thoroughly check the system before operation.
Prepare units for installation as follows:
1. Compare the electrical data on the unit nameplate with
ordering and shipping information to verify that the correct
unit has been shipped.
2. Keep the cabinet covered with the original packaging until
installation is complete and all plastering, painting, etc. is
finished.
3. Verify refrigerant tubing is free of kinks or dents and that it
does not touch other unit components.
4. Inspect all electrical connections. Connections must be
clean and tight at the terminals.
5. Remove any blower support packaging (water-to-air
units only).
6. Locate and verify any hot water generator (HWG), hanger,
or other accessory kit located in the compressor section
or blower section.

CAUTION!
CAUTION! DO NOT store or install units in corrosive
environments or in locations subject to temperature or
humidity extremes (e.g., rooftops, etc. See Tables 9a
and 9b for acceptable temperature ranges). 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.
Duct System Installation
The duct system should be sized to handle the design
airflow quietly. Refer to Figure 6a and 6b for horizontal duct
system details or Figure 2 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 will 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 catalog specifications 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 insure 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.
The installation of geothermal heat pump units and all
associated components, parts and accessories which
make up the GHP system 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.

Vertical Installation
Vertical Unit Location
Packaged 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 the unit from the installed location.
Vertical units are typically installed in a mechanical closet
or basement. 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).
Also, provide sufficient room to make water, electrical, and
duct connection(s).
If the unit is located in a confined space, such as a closet,
provisions must be made for return air to freely enter the
space by means of a louvered door or other method. Any
access panel screws that would be difficult to remove after
the unit is installed should be removed prior to setting
the unit. Refer to Figures 1 and 2 for typical installation
illustrations. Refer to unit catalog specifications for
dimensional data.
1. Install the unit on a piece of rubber, neoprene or other
mounting pad material for sound isolation. The pad
should be at least 3/8” [10mm] to 1/2” [13mm] in
thickness. Extend the pad beyond all four edges of the
unit.
2. Do not block filter access with piping, conduit or
other materials. Refer to unit catalog specifications for
dimensional data.
3. Provide access to water valves and fittings and
screwdriver access to the unit side panels, discharge
collar and all electrical connections.

Sound Attenuation for Vertical Units
Sound attenuation is achieved by enclosing the unit within a
small mechanical room or a closet. Additional measures for
sound control include the following:
1.
If free return, mount the unit so that the return air inlet
is 90° to the return air grille (refer to Figure 3). Install a
sound baffle as illustrated to reduce line-of sight sound
transmitted through return air grilles.
2.
Mount the unit on a Tranquility® Unit Isolation Pad to
minimize vibration transmission to the building structure.
For more information on Tranquility® Unit Isolation Pads,
contact your distributor.

Horizontal Installation
Horizontal Unit Location
Packaged units are not designed for outdoor installation.
Locate the unit in an INDOOR area that allows enough
space for service personnel to perform typical maintenance
or repairs without removing unit from the ceiling. Horizontal
units are typically installed above a false ceiling or in a ceiling
plenum. Never install units in areas subject to freezing or
where humidity levels could cause cabinet condensation
(such as unconditioned spaces subject to 100% outside air).
Consideration should be given to access for easy removal of
the filter and access panels. Provide sufficient room to make
water, electrical, and duct connection(s).
If the unit is located in a confined space, such as a closet,
provisions must be made for return air to freely enter the space
by means of a louvered door or any other method. Any access
panel screws that would be difficult to remove after the unit is
installed should be removed prior to setting the unit. Refer to
Figures 7a and 7b for an illustration of a typical installation.
Refer to unit catalog specifications for dimensional data.
Conform to the following guidelines when selecting a
unit location:
1. Provide a hinged access door in concealed-spline or
plaster ceilings. Provide removable ceiling tiles in T-bar
or lay-in ceilings. Refer to horizontal unit dimensions for
specific series and model in unit catalog specifications.
Size the access opening to accommodate the service
technician during the removal or replacement of the
compressor and the removal or installation of the unit
itself.
2. Provide access to hanger brackets, water valves and
fittings. Provide screwdriver clearance to access panels,
discharge collars and all electrical connections.
3. DO NOT obstruct the space beneath the unit with piping,
electrical cables and other items that prohibit future
removal of components or the unit itself.
4. Use a manual portable jack/lift to lift and support the
weight of the unit during installation and servicing.
The installation of geothermal heat pump units and all
associated components, parts and accessories which
make up the GHP system shall be in accordance with the
regulations of ALL authorities having jurisdiction and MUST
conform to all applicable codes. It is the responsibility of
the installing contractor to determine and comply with ALL
applicable codes and regulations.
Mounting Horizontal Units
Horizontal units have hanger kits pre-installed from the
factory as shown in Figure 5. Figures 7a and 7b shows a
typical horizontal unit installation.
Horizontal heat pumps are typically suspended above a
ceiling or within a soffit using field supplied, threaded rods
sized to support the weight of the unit.
Use four (4) field supplied threaded rods and factory provided
vibration isolators to suspend the unit. Hang the unit clear
of the floor slab above and support the unit by the mounting
bracket assemblies only. DO NOT attach the unit flush with
the floor slab above.
Pitch the unit toward the drain as shown in Figure 6 to
improve the condensate drainage. On small units (less
than 2.5 Tons/8.8 kW) ensure that unit pitch does not cause
condensate leaks inside the cabinet.
NOTE: The top panel of a horizontal unit is a structural
component. The top panel of a horizontal unit must never
be removed from an installed unit unless the unit is properly
supported from the bottom. Otherwise, damage to the unit
cabinet may occur.

Condensate and Water Connection
Condensate Piping
Pitch the unit toward the drain as shown in Figure 6 to
improve the condensate drainage. On small units (less
than 2.5 tons/8.8 kW), insure 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 9. Design the depth of the trap (waterseal) based upon the amount of External Static Pressure
(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.
Water Connections-Residential (Distributor) Models
Residential models utilize swivel piping fittings for water
connections that are rated for 450 psi (3101 kPa) operating
pressure. The connections have a rubber gasket seal similar
to a garden hose gasket, which when mated to the flush
end of most 1” threaded male pipe fittings provides a leakfree seal without the need for thread sealing tape or joint
compound. Check for burrs and ensure that the rubber seal
is in the swivel connector prior to attempting any connection
(rubber seals are shipped attached to the swivel connector).
DO NOT OVER TIGHTEN or leaks may occur.
The female locking ring is threaded onto the pipe threads
which holds the male pipe end against the rubber gasket,
and seals the joint. HAND TIGHTEN ONLY! DO NOT
OVERTIGHTEN!
Figure 11: Water Connections
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.

R e v. : 1 7 J a n . , 2 0 1 3 B
vFlow™ Heat Pump Applications Overview
vFlow™ is a revolutionary new, intelligent, and efficient way to
circulate water (or water plus antifreeze) using INTERNAL,
variable water flow control. The factory-installed highefficiency variable-speed pump uses 60%-80% less wattage
than a traditional fixed speed pump. vFlow™ technology
improves performance of the unit by reducing the amount
of energy required to optimize the flow of water throughout
a GHP System and also reduces the space, cost, and labor
required to install external water flow control mechanisms
(flow controllers, solenoid and flow control valves).
vFlow™ Configurations:
1) Internal Flow Controller - For Closed
Loop Applications
This is the most common configuration for closed loops.
With this factory-installed standard option, the unit is
built with an Internal Variable Speed Pump and other
components to flush and operate the unit correctly
(including an expansion tank, flush ports and flushing
valves). The pump speed is controlled by the DXM2
control based on the difference in entering and leaving
water temperatures (∆T). The Internal Flow Controller
pump includes an internal check valve for multiple unit
installations. A copper water coil is standard with this
option.
Note: Internal Flow Controllers are also very suitable
for multiple unit installations depending on pump
performance requirements.
2) Internal Modulating Motorized Valve – For Large
Closed Loop Applications (external central pumping)
Primarily for use on multi-unit closed loop applications
with central pumping. With this factory-installed option,
the unit includes a low pressure drop modulating
motorized valve that is controlled by the DXM2
microprocessor control based on the difference in the
entering and leaving water temperatures (∆T). A Copper
Water Coil is standard with this option. The modulating
valve in this option has a higher Cv than the open loop
option.
3) Internal Modulating Motorized Valve - For Open
Loop Applications
For use on open loop applications. With this factoryinstalled, standard option, the unit is built with an
internal modulating motorized valve controlled by
the Communicating DXM2 control board based on
entering and leaving water temperatures (∆T). A low Cv
modulating motorized valve is used for this application to
provide more precise control against the higher system
pressure differential of open loop applications. A CuproNickel water coil comes standard with this option.
Details on these options are included in the following sections
on ground loop and ground water 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.

Closed Loop Heat Pump Applications with Internal Flow Controller
Units with internal flow control come with a built-in variable
speed pump, an expansion tank, flushing ports and threeway valves (used to flush the unit). The variable speed
pump is controlled by the Communicating DXM2 board
based on the difference between the entering and leaving
water temperature (∆T). For operation outside of the normal
entering water temperature range (50° or 60°F - 110°F
for cooling, 30°F-70°F for heating) the DXM2 controller
may automatically adjust the control ∆T to account for
the abnormal entering water temperatures, maintaining
an appropriate flow rate for proper unit operation. When
entering water temperatures are abnormally low for cooling,
or abnormally high for heating, the DXM2 controller will
maintain a constant leaving water temperature which will
allow the unit to operate properly under those conditions.
The internal expansion tank helps to maintain constant loop
pressure despite the natural expansion and contraction of
the loop as the seasons and loop temperatures vary. The
expansion tank also helps to avoid flat loop callbacks.
Figure 12: Internal Flow Controller
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.
NOTICE!
NOTICE! If installing MULTIPLE vFlow™ Internal Variable
Speed Flow Controller units (in parallel) on one loop,
please refer to section ‘Multiple Unit Piping and Flushing’
(later in this document).
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.
The following section will help to guide you through flushing a
unit with internal flow control.
Water Pressure Schrader Ports
The pressure ports built in to the unit are provided as a
means of measuring pressure drop through the water-torefrigerant heat exchanger. The water pressure ports are
schrader ports smaller than refrigerant schrader ports. They
are the same size as tire schrader ports. A digital pressure
gauge is recommended for taking pressure readings
through these ports. The water flow through the unit can be
determined by measuring the water pressure at the “water
pressure out” port and subtracting it from the water pressure
at the “water pressure in” port. Comparing the pressure
differential to the pressure drop table (wpd)/flow rate in
Tables 15a through 15d in this manual will determine the flow
rate through the unit.
Piping Installation
The typical closed loop ground source system is shown in
Figures 6a and 11a. All earth loop piping materials should be
limited to polyethylene fusion only for in-ground sections of the
loop and it is also recommended for inside piping. 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 ground
loop applications. 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.

Flushing the Earth Loop
Once piping is completed between the unit and the ground
loop, final purging and charging of the loop is needed.
A flush cart (at least a 1.5 hp [1.1kW] pump) is needed
to achieve adequate flow velocity in the loop to purge air
and dirt particles from the loop itself. Antifreeze solution is
used in most areas to prevent freezing. All air and debris
must be removed from the earth loop piping system before
operation, Flush the loop with a high volume of water at
a high velocity (2 fps [0.6 m/s] in all piping), using a filter
in the loop return line, of the flush cart to eliminate debris
from the loop system. See Table 17 for flow rate required to
attain 2fps [0.6 m/s]. The steps below must be followed for
proper flushing.
WARNING!

injury or death from electrical shock.

Units with internal variable speed pumps also include a
check valve internal to the pump. It is not possible to flush
backwards through this pump. Care must be taken to
connect the flush cart hoses so that the flush cart discharge is
connected to the “water in” flushing valve of the heat pump.
NOTICE: A hydrostatic pressure test is required on ALL piping,
especially underground piping before final backfill per IGSHPA
and the pipe manufacturers recommendations.

Fill loop (valve position A, see Figure 15a) with water from a

to ensure an even fill and increase flushing speed. When
water consistently returns back to the flush reservoir, switch

Switch to valve Position A. The supply water may be shut off
and the flush cart turned on to begin flushing. Once the flush
reservoir is full, do not allow the water level in the flush cart
tank to drop below the pump inlet line or air can be pumped
back out to the earth loop. Try to maintain a fluid level in the
tank above the return tee so that air can not be continuously
mixed back into the fluid. Surges of 50 psi [345 kPa] can
be used to help purge air pockets by simply shutting off
the flush cart return valve going into the flush cart reservoir.
This process ‘dead heads’ the pump to 50 psi [345 kPa]. To
dead head the pump until maximum pumping pressure is
reached, open the valve back up and a pressure surge will
be sent through the loop to help purge air pockets from the
piping system. Notice the drop in fluid level in the flush cart
tank. If all air is purged from the system, the level will drop
only 3/8” in a 10” [25.4 cm] diameter PVC flush tank (about
a half gallon [1.9 liters]) since liquids are incompressible. If
the level drops more than this level, flushing should continue
since air is still being compressed in the loop fluid. Do this a
number of times.

Pressurize and Operate
As shown in Figure 15e, close the flush cart return valve
to pressurize the loop to at least 50 psi [345 kPa], not to
exceed 75 psi [517 kPa]. Open the isolation valve to the
expansion tank and bleed air from the expansion tank piping
using the schraeder valve located in front of the expansion
tank. This will allow loop pressure to compress the
expansion tank bladder, thus charging the expansion tank
with liquid. After pressurizing, close the flush cart supply
valve to isolate the flush cart. Move the Flow Controller
valves to Position D.
Loop static pressure will fluctuate with the seasons and
pressures will be higher in the winter months than during
the cooling season. This fluctuation is normal and should
be considered when charging the system initially. Unhook

Multiple Unit Piping and Flushing
Often projects require more than one heat pump. Where
possible, it makes sense for multiple units to share a common
ground loop. Common ground loops for multiple units bring
new challenges including the need to avoid backward flow
through inactive units, increased pumping requirements,
and more complex flushing needs. Three types of multiple
unit systems are described below along with guidelines for
installation of each type.
vFlow™ internal variable flow technology is a great assist
for systems with multiple units. vFlow™ is available in three
different configurations:
1. Internal variable-speed pump
2. Internal modulating valve for closed loops
3. Internal modulating valve for open loops
The internal modulating valve for open loops version should
never be used on closed loops.
The internal variable speed pump version of vFlow™includes
an internal Magna variable speed circulator controlled by
the DXM2 microprocessor, internal 3-way flushing valves,
an internal bladder type expansion tank, and front-mounted
pressure ports that allow access to the pressure drop across
the coaxial heat exchanger only. The Magna pump includes
an internal check valve. The pump curve for the Magna
circulator is shown in Figure 13. The internal expansion tank
will operate as a pressure battery for the geothermal system.
It will absorb fluid from the loop when loop pressure rises
and inject fluid into the loop when loop pressure falls. In this
way the expansion tank will help to maintain a more constant
loop pressure and avoid flat loops due to seasonal pressure
changes in the loop.
When using the internal variable speed pump as the loop
pump in multiple unit installations it is important to ensure
that the variable speed pump can provide adequate flow
through the heat pump against the loop head when all units
are operating.
It may be possible to flush a multiple unit system through
the unit’s flushing valves. Flushing pressure drop of the
valve may be calculated to determine if it is acceptable.
Engineering data for the 3-way flushing valves can be found
in Table 2.

For example, if a system includes two 2-ton units and four ¾
loop circuits we can calculate the flushing pressure drop as
follows. From Table 1 we know that it will take 4 gpm to flush
each ¾” circuit. If there is no provision to isolate the circuits
for flushing, we will have to flush with a minimum of 4 circuits
x 4 gpm/circuit = 16 gpm total. A check of other piping sizes
used must be done to ensure that 16 gpm total flow will flush
all piping.
Pressure drop through the flushing valve can be calculated
using the following formula.
∆P = (GPM/Cv)2 where,
∆P = pressure drop in psi through the valve while flushing
GPM = flushing flow in gallons per minute
Cv = valve Cv in flushing mode
We know from Table 2 that the Cv for the flushing valve in
a TE026 is 10.3 in the flushing mode (90° flow). Therefore,
∆P = (GPM/Cv)2 = (16/10.3)2 = 2.4 psi per valve (there are
two flushing valves). So long as the flushing pump is able to
provide 16 gpm at the flushing pressure drop of the loop plus
the 2.4 x 2 valves = 4.8 psi of the flushing valves, the internal
flushing valves may be used. If the flushing pump is not able
to overcome the pressure drop of the internal flushing valves,
then larger external flushing valves must be used.
Unit Configuration
Multiple vFlow™ units with internal variable-speed flow
controller and check valve, piped in parallel sharing a
common loop MUST be configured for ‘VS PUMP PARALLEL’

Multiple Units with Internal Flow Controllers
The simplest multiple unit system is one with two (or more)
units utilizing internal Flow Controllers with no external
pumps or flushing valves. In this case the units are piped
in parallel and use the internal flushing valves to flush the
system. The variable speed pump includes an internal check
valve to prevent back (short circuiting) flow through the units.
In this case, flush the loop through the internal flushing
valves in the unit farthest from the loop first. Once the loop is
flushed, then change the internal flushing valves to flush the
heat pump. Next, move the flushing cart to the next closest
unit to the loop.

Multiple Unit Piping and Flushing
Again, flush the loop through the internal flushing valves. This is important as there may be air/debris in the lines from this unit
to the common piping. Once flushing begins the air will be move into the loop and will need to be flushed out. After the loop
is flushed through the second unit, change the flushing valves to flush the second unit. This process should be repeated for
additional units working from the farthest from the loop to the closest to the loop.
This type of application can generally be employed for systems to 12 tons depending on loop design. However, it is important
perform appropriate calculations to confirm that the variable speed pump can provide adequate flow through all heat pumps
against the loop head when all units are operating.

Multiple Units with Internal Flow Controllers and External Flushing Valves
When the number of units or flushing requirements reaches a point where it is no longer feasible to flush through the internal
valves (generally systems of more than 12 tons depending on loop design), external flushing valves should be installed. In this
case, three-way flushing valves should be used or additional isolation valves must be installed to be able to isolate the loop
during flushing.

First, flush the ground loop. The installer should close the indoor loop shut-off valve (or the internal flushing valves in all units)
and open the ground loop shut-off valve to prevent flow through the indoor loop while flushing the ground loop.
Once the ground loop is flushed, close the ground loop shut-off valve and open the indoor loop valve(s) to flush the units and
indoor piping. Remember that there is an internal check valve in the variable speed pump and that backward flow the unit is
not possible.

This is an application where multiple units are used in

Before flushing, the installer should manually open all

Central Pumping section of this manual. Next, flush the
ground loop. The installer should close a pump isolation
valve and open the ground loop shut-off valve to prevent flow
through the indoor loop while flushing the ground loop.
Once the ground loop is flushed, close the ground loop
shut-off valve and open the pump isolation valve to flush
the units and indoor piping. Once the system is flushed
remember to return the modulating valves to their normal
operating position.

Antifreeze Selection - General
In areas where minimum entering loop temperatures drop
below 40°F [4.4°C] or where piping will be routed through
areas subject to freezing, antifreeze is needed. Alcohols
and glycols are commonly used as antifreeze solutions.
Your local representative should be consulted for the
antifreeze best suited to your area. Freeze protection should
be maintained to 15°F [8.5°C] below the lowest expected
entering loop temperature.
Initially calculate the total volume of fluid in the piping
system using Table 3. Then use the percentage by volume
shown in Table 4 for the amount of antifreeze. Antifreeze
concentration should be checked from a well mixed sample
using a hydrometer to measure specific gravity.
Contact your ClimateMaster distributor if you have any
questions as to antifreeze selection.
WARNING!
WARNING! Always use properly marked vehicles (D.O.T.
placards), and clean/suitable/properly identified containers
for handling flammable antifreeze mixtures. Post and
advise those on the jobsite of chemical use and potential
dangers of handling and storage.
NOTICE: DO NOT use automotive windshield washer fluid
as antifreeze. Washer fluid contains chemicals that will cause
foaming.

Antifreeze Charging
It is highly recommended to utilize premixed antifreeze fluid
where possible to alleviate many installation problems and
extra labor.
The following procedure is based upon pure antifreeze and
can be implemented during the Full Flush procedure with three
way valves in the Figure 15d - Valve Position C. If a premixed
mixture of 15°F [-9.4°C] freeze protection is used, the system
can be filled and flushed with the premix directly to prevent
handling pure antifreeze during the installation.
1) Flush loop until all air has been purged from system and
pressurize to check for leaks before adding
any antifreeze.
2) Run discharge line to a drain and hook up antifreeze
drum to suction side of pump (if not adding below
water level through approved container). Drain flush cart
reservoir down to pump suction inlet so reservoir can
accept the volume of antifreeze to be added.
3) Calculate the amount of antifreeze required by first
calculating the total fluid volume of the loop from Table 3.
Then calculate the amount of antifreeze needed using Table
2 for the appropriate freeze protection level. Many southern
applications require freeze protection because of exposed
piping to ambient conditions.
4) Isolate unit and prepare to flush only through loop (see
Figure 15a). Start flush cart, and gradually introduce the
required amount of liquid to the flush cart tank (always
introduce alcohols under water or use suction of pump
to draw in directly to prevent fuming) until attaining the
proper antifreeze protection. The rise in flush reservoir
level indicates amount of antifreeze added (some carts
are marked with measurements in gallons or liters). A
ten inch [25.4 cm] diameter cylinder, 3 foot [91.4 cm] tall
holds approximately 8 gallons [30.3 liters] of fluid plus the
hoses (approx. 2 gallons, [7.6 liters], which equals about

10 gallons [37.9 liters] total. If more than one tankful is
required, the tank should be drained immediately by
opening the waste valve of the flush cart noting the
color of the discharge fluid. Adding food coloring to the
antifreeze can help indicate where the antifreeze is in the
circuit and prevents the dumping of antifreeze out the
waste port. Repeat if necessary.
5) Be careful when handling methanol (or any alcohol).
Always wear eye protection and rubber gloves. The
fumes are flammable, and care should be taken with all
flammable liquids. Open flush valves to flush through
both the unit and the loop and flush until fluid is
homogenous and mixed. It is recommended to run the
unit in the heating and cooling mode for 15-20 minutes
each to ‘temper’ the fluid temperature and prepare it for
pressurization. Devoting this time to clean up can be
useful. This procedure helps prevent the periodic “flat”
loop condition.
6) Close the flush cart return valve; and immediately
thereafter, close the flush cart supply valve, leaving a
positive pressure in the loop of approximately 50 psi [345
kPa]. This is a good time to pressure check the system
as well. Check the freeze protection of the fluid with the
proper hydrometer to ensure that the correct amount of
antifreeze has been added to the system. The hydrometer
can be dropped into the flush reservoir and the reading
compared to Chart 1a for Methanol, 1b for Propylene
Glycol, and 1c for Ethanol to indicate the level of freeze
protection. Do not antifreeze more than a +10°F [-12.2°C]
freeze point. Specific gravity hydrometers are available
in the residential price list. Repeat after reopening and
flushing for a minute to ensure good second sample
of fluid. Inadequate antifreeze protection can cause
nuisance low temperature lockouts during cold weather.

Tranquility Digital packaged units are available with a
modulating water valve option for closed-loop applications
with external central pumping (designated by a 5 in the 11th
position of the unit model number). With this option, the
Modulating Valve is regulated by the Communicating DXM2
board based on entering and leaving water temperature (∆T).
The DXM2 board outputs a 0-10v signal to determine valve
position (flow rate). The modulating valve defaults to closed
position if it loses signal but still has 24V power running to
it. If the motorized modulating valve loses both signal from
the DXM2 board AND 24V power, it will remain in the same
position it was in when it lost 24V power.
Note: The Cv (flow coefficient) of the valve used in these
units is DIFFERENT that the Cv of the valve used in the
open loop unit. It is not advisable for use in open loop
applications as sound/noise issues may result. Units with
the water circuit for closed loop, central pumping option are
only available with a copper water coil.

Open Loop - Ground Water Systems
Typical open loop piping is shown in Figure 19. 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. Schrader ports built into
unit may be used to measure heat exchanger pressure drop.
Water temperature can be viewed on the communicating
thermostat. Piping materials should be limited to copper, PE,
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 requirements. vFlow™ units for open
loop applications always come with Cupro-Nickel coils. In
ground water situations where scaling could be heavy or
where biological growth such as iron bacteria will be present,
an open loop system is not recommended. Heat exchanger
coils may over time lose heat exchange capabilities due to
build up of mineral deposits. Heat exchangers must only
be serviced by a qualified technician, as acid and special
pumping equipment is required. Desuperheater coils can
likewise become scaled and possibly plugged. In areas with
extremely hard water, the owner should be informed that the
heat exchanger may require occasional acid flushing. In some
cases, the desuperheater option should not be recommended
due to hard water conditions and additional maintenance
required.
Water Quality Standards
Table 3 should be consulted for water quality requirements.
Scaling potential should be assessed using the pH/Calcium
hardness method. If the pH <7.5 and the Calcium hardness
is less than 100 ppm, scaling potential is low. If this method
yields numbers out of range of those listed, 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.
Pressure Tank and Pump
Use a closed, bladder-type pressure tank to minimize
mineral formation due to air exposure. The pressure 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.

Open Loop or Ground-Water Heat Pump Applications
The pump should be sized to handle the home’s domestic
water load (typically 5-9 gpm [23-41 l/m]) plus the flow rate
required for the heat pump. Pump sizing and expansion
tank must be chosen as complimentary items. For example,
an expansion tank that is too small can cause premature
pump failure due to short cycling. Variable speed pumping
applications should be considered for the inherent energy
savings and smaller pressure tank requirements.
Water Coil Low Temperature Limit Setting
For all open loop systems the 30°F [-1.1°C] LT1 setting
(factory setting-water) should be used to avoid freeze
damage to the unit. See “Low Water Temperature Cutout
Selection” (Figure 17) in this manual for details on the low
limit setting.

Hot Water Generator
The HWG (Hot Water Generator) or desuperheater option
provides considerable operating cost savings by utilizing
heat energy from the compressor discharge line to help
satisfy domestic hot water requirements. The HWG is active
throughout the year, providing virtually free hot water when
the heat pump operates in the cooling mode or hot water at
the COP of the heat pump during operation in the heating
mode. Actual HWG water heating capacities are provided in
the appropriate heat pump performance data.
Heat pumps equipped with the HWG option include a builtin water to refrigerant heat exchanger that eliminates the
need to tie into the heat pump refrigerant circuit in the field.
The control circuit and pump are also built in for residential
equipment. The figure to the left shows a typical example
of HWG water piping connections on a unit with built-in
circulating pump. This piping layout prevents sludge/debris
from the bottom of the tank being pulled into the HWG pump.
Typically a single tank of at least 50 gallons (189 liters) is
used to limit installation costs and space. However, a dual
tank, as shown in the HWG Double Tank Installation Figure,
is the preferred system, as it provides the maximum storage
and temperate source water to the HWG.
It is always advisable to use water softening equipment on
domestic water systems to reduce the scaling potential and
lengthen equipment life. In extreme water conditions, it may
be necessary to avoid the use of the HWG option since the
potential cost of frequent maintenance may offset or exceed
any savings. Consult Table 3 for scaling potential tests.
Typical Single Tank HWG Installation

The temperature set point of the HWG is field selectable
to 125°F or 150°F . The 150°F set point allows more heat
storage from the HWG. For example, consider the amount
of heat that can be stored by the HWG when using the 125°F
set point, versus the amount of heat that can be generated
by the HWG when using the 150°F set point.

In a typical 50 gallon two-element electric water heater
the lower element should be turned down to 100°F, or the
lowest setting, to get the most from the HWG. The tank will
eventually stratify so that the lower 80% of the tank, or 40
gallons, becomes 100°F (controlled by the lower element).
The upper 20% of the tank, or 10 gallons, will be maintained
at 125°F (controlled by the upper element).
Using a 125°F set point, the HWG can heat the lower 40
gallons of water from 100°F to 125°F, providing up to 8,330
btu’s of heat. Using the 150°F set point, the HWG can heat
the same 40 gallons of water from 100°F to 150°F and the
remaining 10 gallons of water from 125°F to 150°F, providing
a total of up to 18,743 btu’s of heat, or more than twice as
much heat as when using the 125°F set point.

The DXM2 microprocessor control monitors the refrigerant
and water temperatures to determine when to operate
the HWG. The HWG will operate any time the refrigerant
temperature is sufficiently above the water temperature.
Once the HWG has satisfied the water heating demand
during a heat pump run cycle, the controller will cycle the
pump at regular Intervals to determine if an additional HWG
cycle can be utilized.
When the control is powered and the HWG pump output is
active for water temperature sampling or HWG operation,
the DXM2 status LED will slowly flash (On 1 second, Off 1
second).
WATER HEATER
Hot Water Generator settings are determined by DIP
switches 3-2, 3-3, and 3-4.
If the control has detected a HWG fault, the DXM2 status
LED will flash a numeric fault code as follows:
DIP 3-2 controls the HWG Test Mode. It provides for forced
operation of the HWG output, activating the HWG pump for
up to five minutes. ON = HWG test mode, OFF = normal
HWG operation. The control will revert to standard operation
after five minutes regardless of switch position.

“Compressor Discharge sensor fault” will be six flashes 0.3
seconds long, then a 10 second pause, then six flashes
again, etc.
DIP 3-4 is for the HWG status. It provides HWG operation
control. ON = HWG mode enabled, OFF = HWG mode
disabled. Units are shipped from the factory with this switch

WARNING!
WARNING! The HWG pump Is fully wired from the
factory. Use extreme caution when working around
the microprocessor control as it contains line voltage
connections that presents a shock hazard that can cause
severe injury or death!
The heat pump, water piping, pump, and hot water tank
should be located where the ambient temperature does
not fall below 50°F [10°C]. Keep water piping lengths at a
minimum. DO NOT use a one way length greater than 50 ft.
(one way) [15 m]. See Table 4 for recommended piping sizes
and maximum lengths.
All installations must be in accordance with local codes. The
installer is responsible for knowing the local requirements,
and for performing the installation accordingly. DO NOT
activate the HWG (turn DIP 3-4 to the ON position) until
“Initial Start-Up” section, below is completed. Powering the
pump before all installation steps are completed will damage
the pump.
Water Tank Preparation
1. Turn off power or fuel supply to the hot water tank.
2. Connect a hose to the drain valve on the water tank.
3. Shut off the cold water supply to the water tank.
4. Open the drain valve and open the pressure relief valve
or a hot water faucet to drain tank.
5. When using an existing tank, it should be flushed with
cold water after it is drained until the water leaving the
drain hose is clear and free of sediment.
6. Close all valves and remove the drain hose.
7. Install HWG water piping.
HWG Water Piping
1. Using at least 1/2” [12.7mm] I.D. copper, route and install
the water piping and valves as shown in Figures 20 or
21. Install an approved anti-scald valve if the 150°F HWG
setpoint is or will be selected. An appropriate method
must be employed to purge air from the HWG piping.
This may be accomplished by flushing water through the
HWG (as in the figures on page 23) or by installing an air
vent at the high point of the HWG piping system.
2. Insulate all HWG water piping with no less than 3/8”
[10mm] wall closed cell insulation.
3. Open both shut off valves and make sure the tank drain
valve is closed.
Water Tank Refill
1. Close valve #4. Ensure that the HWG valves (valves #2
and #3) are open. Open the cold water supply (valve #1)
to fill the tank through the HWG piping. This will force
water flow through the HWG and purge air from the
HWG piping.
2. Open a hot water faucet to vent air from the system until
water flows from faucet; turn off faucet. Open valve #4.
3. Depress the hot water tank pressure relief valve handle to
ensure that there is no air remaining in the tank.
4. Inspect all work for leaks.
5. Before restoring power or fuel supply to the water heater,
adjust the temperature setting on the tank thermostat(s)
to insure maximum utilization of the heat available from
the refrigeration system and conserve the most energy.
On tanks with both upper and lower elements and
thermostats, the lower element should be turned down
to 100°F [38°C] or the lowest setting; the upper element
should be adjusted to 120-130°F [49-54°C]. Depending
upon the specific needs of the customer, you may want
to adjust the upper element differently. On tanks with a
single thermostat, a preheat tank should be used (HWG
Double Tank Installation Figure on page 23).
6. Replace access cover(s) and restore power or
fuel supply.
Initial Start-Up
1. Make sure all valves in the HWG water circuit are
fully open.
2. Turn on the heat pump and allow it to run for
10-15 minutes.
3. Set S3-4 to the “ON” position (enabled) to engage the
HWG. See Figure *.
4. The HWG pump should not run if the compressor is not
running.
5. The temperature difference between the water entering
and leaving the HWG coil should be approximately
5-10°F [3-6°C].
6. Allow the unit to operate for 20 to 30 minutes to insure
that it is functioning properly.

Electrical - Thermostat Wiring and Auxiliary Heat
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 due to air infiltration through the
wall cavity. 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 or larger wire.
Wire the appropriate thermostat as shown in Figures 26a and
26b to the low voltage terminal strip on the DXM2 control
board. Practically any heat pump thermostat will work with
these units, provided it has the correct number of heating
and cooling stages. However, using the communicating
thermostat (ATC32U**) is highly recommended for on-site,
easier configuration, monitoring and diagnosis.

ECM Blower Control
The ECM fan is controlled directly by the DXM2 control board
that converts thermostat inputs and CFM settings to signals
used by the ECM motor controller. To take full advantage of
the ECM motor features, an iGate™ communicating multistage thermostat should be used (ATC32U**).
The DXM2 control maintains a selectable operating airflow
[CFM] for each heat pump operating mode. For each
operating mode there are maximum and minimum airflow
limits. See the ECM Blower Performance tables for the
maximum, minimum, and default operating airflows.
Airflow levels are selected using the configuration menus of
a communicating thermostat (ATC32U**) or diagnostic tool
(ACDU**). The configuration menus allow the installer to
independently select and adjust the operating airflow for each
of the operating modes. Air flow can be selected in 25 CFM
increments within the minimum and maximum limits shown in
Table 8. The blower operating modes include:
• First Stage Cooling (Y1 & O)
• Second Stage Cooling (Y1, Y2, & O)
• First Stage Cooling in Dehumidification Mode
(Y1, O, & Dehumid)
• Second Stage Cooling in Dehumidification Mode
(Y1, Y2, O, & Dehumid)
• First Stage Heating (Y1)
• Second Stage Heating (Y1 & Y2)
• Third Stage (Auxiliary) Heating (Y1, Y2, & W)
• Emergency Heating (W with no Y1 or Y2)
• Fan (G with no Y1, Y2, or W)
Special Note for AHRI Testing: To achieve rated airflow for
AHRI testing purposes, it is necessary to change the CFM
settings to rated airflow.

It is necessary to use the ATC32U** communicating
thermostat to engage the Auto Dehumidification feature on
units with Internal Flow Controllers. Units with Internal Flow
Controllers utilize the ‘H’ terminal on the DXM2 as an input
for an ambient temperature switch. Units without the Internal
Flow Controller option use the ‘H’ terminal on the DXM2
controller to initiate the Auto Dehumidification mode. Refer to
the DXM2 AOM for more information (part #97B0003N15).
The ECM motor includes “soft start” and “ramp down”
features. The soft start feature is a gentle increase of motor
rpm at blower start up. This creates a much quieter blower
start cycle.
The ramp down feature allows the blower to slowly decrease
rpm to a full stop at the end of each blower cycle. This
creates a much quieter end to each blower cycle and adds
overall unit efficiency.
The ramp down feature is eliminated during an ESD
(Emergency Shut Down) situation. When the DXM2 ESD
input is activated, the blower and all other control outputs are
immediately de-activated.
The duration of the “ramp down” periods are adjustable from
0 seconds to 255 seconds. This adjustment is available
in the Aiflow Selection screen using the communicating
thermostat or configuration/diagnostics tool, see Figure 27.

DXM2 Controls
DXM2 iGate™ Controller DXM2 is the next generation in
controls and is capable of 2-way communication with smart
components, like the communicating iGate™ thermostat,
ECM fan motor, Magna Variable-Speed Pump and
configuration/diagnostic tool.
For most residential applications, configuration, monitoring
and diagnostics can all be done from the thermostat/ service
tool so there’s no need to read LEDs and change DIP switches.
For details on user settings, refer to iGate™ Communicating
Thermostat User Manual (part # 97B0055N02).
For details on Installer settings (not to be used by
consumers), refer to iGate™ Communicating Thermostat
Installer manual (part # 97B0055N03).
For details on installer/service settings on the iGate™
configuration/diagnostic tool, refer to operation manual (part
# 97B0106N01).
For further details on the DXM2 control, refer to the DXM2
Application, Operation and Maintenance Manual (part #
97B0003N15). The DXM2 AOM is shipped with each unit.
Thermostat compatibility
It is strongly recommended that iGate™ communicating
thermostat (ATC32U**) or iGate™ configuration/ diagnostic
tool (ACDU**) be used with DXM2 control, to ensure easy
configuration, monitoring and diagnostics, in PLAIN English.
For example, Airflow CAN NOT be configured without either
the communicating thermostat or configuration/ diagnostic
tool
Field Hardware Configuration Options - Note: In the
following field hardware configuration options, changes
should be made ONLY when power is removed from the
DXM2 control.
settings on Residential units. All DIP switches in S1 and
S2 should be “on”. In S3, S3-1 should be “on” and the rest
should be “off”. For more details on DIP switches, refer to
the DXM2 AOM (part # 97B0003N15).
DXM2 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.
Test Mode Button
Test mode allows the service technician to check the
operation of the control in a timely manner. By momentarily
pressing the TEST push button, the DXM2 control enters a
20 minute test mode period in which all time delays are sped
up 15 times.

Low Water Temperature Cutout Selection
The DXM2 control allows the field selection of low water
(or water-antifreeze solution) temperature limit by clipping
jumper JW3, which changes the fault cutout 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). 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.

Unit Commissioning And Operating Conditions
Operating Limits
Environment – Units are designed for indoor installation only. Never install units in areas subject to freezing or where humidity levels
could cause cabinet condensation (such as unconditioned spaces subject to 100% outside air).
Power Supply – Voltage utilization shall comply with AHRI standard 110.
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 insure 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 9a for operating limits.

Unit Start-Up and Operating Conditions
Unit and System Checkout
BEFORE POWERING SYSTEM, please check the following:
UNIT CHECKOUT
Shutoff valves: Insure that all isolation valves are open.
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. Residential 208-230V units
are factory wired for 230V operation unless specified
otherwise.
Loop/water piping is complete and purged of air. Water/
piping is clean.
Antifreeze has been added if necessary.
Entering water and air: Insure that entering water and air
temperatures are within operating limits of Tables 10a
and 10b.
Low water temperature cutout: Verify that low water
temperature cut-out on the DXM2 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 start-up. Fan motors are preoiled at the factory. Check unit fan CFM selection and
compare to design requirements.
Condensate line: Verify that condensate trap is installed
and pitched.
HWG is switched off at SW 3-4 unless piping is
completed and air has been purged from the system.
Unit air coil and filters: Insure that filter is clean and
accessible. Clean air coil of all manufacturing oils.
Unit controls: Verify that DXM2 field selection options are
properly set. Low voltage wiring is complete.
Blower CFM and Water ∆T is set on communicating
thermostats or diagnostic tool.
Service/access panels are in place.
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
system longevity (see Table 5).
System flushing: Verify that all air is purged from the
system. Air in the system can cause poor operation or
system corrosion. Water used in the system must be
potable quality initially and clean of dirt, piping slag,
and strong chemical cleaning agents. Some antifreeze
solutions may require distilled water.
Internal Flow Controller: Verify that it is purged of air 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 set properly
(LT1 - JW3).
38
Miscellaneous: Note any questionable aspects of
the installation.
CAUTION!
CAUTION! Verify that ALL water valves are open and
allow water flow prior to engaging the compressor.
Freezing of the coax or water lines can permanently
damage the heat pump.
CAUTION!
CAUTION! To avoid equipment damage, DO NOT
leave system filled in a building without heat during the
winter unless antifreeze is added to the water loop. Heat
exchangers never fully drain by themselves and will
freeze unless winterized with antifreeze.
Unit Start-up Procedure
1. Turn the thermostat fan position to “ON.” Blower should
start.
2. Turn Blower off.
3. Ensure all valves are adjusted to their full open position.
Ensure line power to the heat pump is on.
4. Room temperature should be within the minimummaximum ranges of listed in the unit IOM. During startup checks, loop water temperature entering the heat
pump should be between 30°F [-1°C] and 95°F [35°C].
5. It is recommended that water-to-air units be first started
in the cooling mode, when possible. This will allow liquid
refrigerant to flow through the filter-drier before entering
the TXV, allowing the filter-drier to catch any debris that
might be in the system before it reaches the TXV.
6. Two factors determine the operating limits of geothermal
heat pumps, (a) return air temperature, and (b) entering
water temperature. When either of the factors is at a
minimum or maximum level, the other factor must be at
normal levels to insure proper unit operation.
a. Place the unit in Manual Operation. When in manual
mode activate Y1,Y2, and O to initiate the cooling
mode. Also manually increase CFM until desired
cooling CFM is achieved. Next adjust pump speed
% until desired loop temperature difference (leaving
water temperature minus entering water temperature)
is achieved. (For modulating valve adjust valve %).

d. Check the elevation and cleanliness of the
condensate lines. Dripping may be a sign of a
blocked line. Check that the condensate trap is filled
to provide a water seal.
e. Turn thermostat to “OFF” position. A hissing noise
indicates proper functioning of the reversing valve.
7. Allow five (5) minutes between tests for pressure to
equalize before beginning heating test.
4-8
10 - 17
c. Verify that the compressor is on and that the water
temperature fall (heating mode) is within normal
range.
e. Check for vibration, noise, and water leaks.
8. If unit fails to operate properly, perform troubleshooting
analysis (see troubleshooting section in the unit IOM).
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.
9. When testing is complete, exit the Installer Menu and set
thermostat to maintain desired comfort level for normal
operation.
10. BE CERTAIN TO FILL OUT AND RETURN ALL
WARRANTY REGISTRATION PAPERWORK.
Unit performance may be verified by calculating the unit
heat of rejection and heat of extraction. Heat of Rejection
(HR) can be calculated and compared to the performance
data pages in this IOM. The formula for HR is as follows:
HR = TD x GPM x 500 (or 485 for anti-freeze solutions),
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 unit heat exchanger pressure
drop to Table 12.
Heat of Extraction (HE) can also be calculated and compared
to the performance data pages in this IOM. The formula for
HE is as follows: HE = TD x GPM x 500 (or 485 for antifreeze solutions), 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 unit heat
exchanger pressure drop to Table 12.

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 [2.0 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 [2.6 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. 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) may produce water (or
debris) velocities that can erode the heat exchanger wall and
ultimately produce leaks.
Hot Water Generator Coils
See water coil maintenance for ground water units. If the
potable water is hard or not chemically softened, the high
temperatures of the desuperheater will tend to scale even
quicker than the water coil and may need more frequent
inspections. In areas with extremely hard water, a HWG is
not recommended.
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 filters. Inspect the drain twice a year to
avoid the possibility of plugging and eventual overflow.
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 residential units have permanently lubricated fan motors.
Further lubrication is not recommended. Conduct annual
amperage check to insure amp draw is no more than 10%
greater than indicated on serial data plate.
Air Coil
The air coil must be cleaned to obtain maximum
performance. Check once a year under normal operating
conditions and, if dirty, brush or vacuum clean. Care must
be taken not to damage the aluminum fins while cleaning.
CAUTION: Fin edges are sharp.
Cabinet
Do not allow water to stay in contact with the cabinet for
long periods of time to prevent corrosion of the cabinet sheet
metal. Generally, vertical cabinets are set up from the floor
a few inches [7 - 8 cm] to prevent water from entering the
cabinet. The cabinet can be cleaned using a mild detergent.
Refrigerant System
To maintain sealed circuit integrity, do not install service
gauges unless unit operation appears abnormal. Reference
the operating charts for pressures and temperatures. Verify
that air and water flow rates are at proper levels before
servicing the refrigerant circuit.
Filters
Filters must be clean to obtain maximum performance.
Filters should be inspected every month under normal
operating conditions and be replaced when necessary. Units
should never be operated without a filter.
Washable, high efficiency, electrostatic filters, when dirty,
can exhibit a very high pressure drop for the fan motor and
reduce air flow, resulting in poor performance. It is especially
important to provide consistent washing of these filters (in
the opposite direction of the normal air flow) once per month
using a high pressure wash similar to those found at selfserve 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
50

Troubleshooting
General
If operational difficulties are encountered, perform
the preliminary checks below before referring to the
troubleshooting charts.
• Verify that the unit is receiving electrical supply power.
• Make sure the fuses in the fused disconnect switches are
intact.
After completing the preliminary checks described above,
inspect for other obvious problems such as leaking
connections, broken or disconnected wires, etc. If everything
appears to be in order, but the unit still fails to operate
properly, refer to the “DXM2 Troubleshooting Process
Flowchart” or “Functional Troubleshooting Chart.”
DXM2 Board
DXM2 board troubleshooting in general is best summarized
as verifying inputs and outputs. After inputs and outputs
have been verified, board operation is confirmed and the
problem must be elsewhere. Below are some general
guidelines for troubleshooting the DXM2 control.
Field Inputs
Conventional thermostat inputs are 24VAC from the
thermostat and can be verified using a voltmeter between C
and Y1, Y2, W, O, G. 24VAC will be present at the terminal
(for example, between “Y1” and “C”) if the thermostat is
sending an input to the DXM2 board.
Proper communications with a thermostat can be verified
using the Fault LED on the DXM2. If the control is NOT
in the Test mode and is NOT currently locked out or in
a retry delay, the Fault LED on the DXM2 will flash very
slowly (1 second on, 5 seconds off), if the DXM2 is properly
communicating with the thermostat.
Sensor Inputs
All sensor inputs are ‘paired wires’ connecting each
component to the board. Therefore, continuity on pressure
switches, for example can be checked at the board
connector. The thermistor resistance should be measured
with the connector removed so that only the impedance of
the thermistor is measured. If desired, this reading can be
compared to the thermistor resistance chart shown in Table
17. An ice bath can be used to check the calibration of the
thermistor.

Troubleshooting
Outputs
The compressor and reversing valve relays are 24VAC
and can be verified using a voltmeter. For units with ECM
blower motors, the DXM2 controls the motor using serial
communications, and troubleshooting should be done with
a communicating thermostat or diagnostic tool. The alarm
relay can either be 24VAC as shipped or dry contacts for use
with DDC controls by clipping the JW1 jumper. Electric heat
outputs are 24VDC “ground sinking” and require a voltmeter
set for DC to verify operation. The terminal marked “24VDC”
is the 24VDC supply to the electric heat board; terminal
“EH1” is stage 1 electric heat; terminal “EH2” is stage 2
electric heat. When electric heat is energized (thermostat
is sending a “W” input to the DXM2 controller), there will
be 24VDC between terminal “24VDC” and “EH1” (stage 1
electric heat) and/or “EH2” (stage 2 electric heat). A reading
of 0VDC between “24VDC” and “EH1” or “EH2” will indicate
that the DXM2 board is NOT sending an output signal to the
electric heat board.
Test Mode
Test mode can be entered for 20 minutes by pressing the
Test pushbutton. The DXM2 board will automatically exit test
mode after 20 minutes.
Advanced Diagnostics
To properly troubleshoot advanced control features,
and to aid in troubleshooting basic control features, a
communicating thermostat or diagnostic tool must be used.
Service Mode
The Service Mode provides the installer with several
functions for troubleshooting, including Manual Operation,
Control Diagnostics, Control Configuration, and Fault
History.
Manual Operation – The Manual Operation mode allows the
installer to bypass normal thermostat timings and operating
modes, to directly activate the thermostat inputs to the
DXM2, activate the DXM2 Test mode, and directly control the
ECM blower, internal flow center, and proportional valve.
Control Diagnostics – The Control Diagnostics menus allow
the installer to see the current status of all DXM2 control
switch inputs, values of all temperature sensor inputs,
control voltage, ECM blower, internal flow center, and
proportional valve operating status and parameters.
Dipswitch Configuration – The Dipswitch Configuration
menus allow the installer to easily see the current DXM2
control configuration.
values when the lockout occurred.
Fault Temp Conditions – This option displays the DXM2
temperature and voltage values when the lockout occurred.
Fault Flow Conditions – This option displays the DXM2 ECM
blower, pump, and valve operating parameters when the
lockout occurred.
Fault I/O Conditions – This option displays the status of
the DXM2 physical and communicated inputs and the relay
outputs when the lockout occurred.
Fault Configuration Conditions – This option displays the
status of the DXM2 option selections when the lockout
occurred.
Fault Possible Causes – This option displays a list of
potential causes of the stored fault.
Clear Fault History – The Clear Fault History option allows
the fault history stored in the non-volatile memory of the
DXM2 to be cleared.
DXM2 Troubleshooting Process Flowchart/Functional
Troubleshooting Chart
The “DXM2 Functional Troubleshooting Process Flowchart”
is a quick overview of how to start diagnosing a suspected
problem, using the fault recognition features of the DXM2
board. The “Functional Troubleshooting Chart” on the
following page is a more comprehensive method for
identifying a number of malfunctions that may occur, and is
not limited to just the DXM2 controls. Within the chart are
five columns:
• The “Fault” column describes the symptoms.
• Columns 2 and 3 identify in which mode the fault is likely
to occur, heating or cooling.
• The “Possible Cause column” identifies the most likely
sources of the problem.
• The “Solution” column describes what should be done to
correct the problem.
WARNING!
WARNING! HAZARDOUS VOLTAGE! DISCONNECT
ALL ELECTRIC POWER INCLUDING REMOTE
DISCONNECTS BEFORE SERVICING.
Failure to disconnect power before servicing can cause
severe personal injury or death.
Fault History – In addition to the fault code, the DXM2 stores
the status of all control inputs and outputs when a fault
condition is detected. The fault history covering the last five
lockout conditions is stored and may be retrieved from the
DXM2. After a specific fault in the fault history is selected,
the operating mode and time when the fault occurred are
displayed, with options to select specific control status
