General Information
Inspection
Upon receipt of the equipment, carefully check the shipment
against the bill of lading. Make sure all units have been
received. Inspect the packaging of each unit, and inspect each
unit for damage. Insure that the carrier makes proper notation
of any shortages or damage on all copies of the freight bill and
completes a common carrier inspection report. Concealed
damage not discovered during unloading must be reported
to the carrier within 15 days of receipt of shipment. If not 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 7a and 7b 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 specifications catalog 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.

Vertical Installation
Vertical Unit Location
Units are not designed for outdoor installation. Locate
the unit in an INDOOR area that allows enough space for
service personnel to perform typical maintenance or repairs
without removing unit from the mechanical room/closet.
Vertical units are typically installed in a mechanical room
or closet. Never install units in areas subject to freezing or
where humidity levels could cause cabinet condensation
(such as unconditioned spaces subject to 100% outside air).
Consideration should be given to access for easy removal of
the filter and access panels. Provide sufficient room to make
water, electrical, and duct connection(s).
If the unit is located in a confined space, such as a closet,
provisions must be made for return air to freely enter the
space by means of a louvered door, etc. Any access panel
screws that would be difficult to remove after the unit is
installed should be removed prior to setting the unit. Refer to
Figures 1 and 2 for typical installation illustrations. Refer to
unit specifications catalog 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. Provide adequate clearance for filter replacement
and drain pan cleaning. Do not block filter access
with piping, conduit or other materials. Refer to unit
specifications for dimensional data.
3. Provide access for fan and fan motor maintenance and
for servicing the compressor and coils without removing
the unit.
4. Provide an unobstructed path to the unit within the
closet or mechanical room. Space should be sufficient to
allow removal of the unit, if necessary.
5. Provide access to water valves and fittings and
screwdriver access to the unit side panels, discharge
collar and all electrical connections.

Vertical Installation
Sound Attenuation for Vertical Units - Sound attenuation
is achieved by enclosing the unit within a small mechanical
room or a closet. Additional measures for sound control
include the following:
1.
Mount the unit so that the return air inlet is 90° to the
return air grille. Refer to Figure 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.
Condensate Piping for Vertical Units - Install condensate
trap at each unit with the top of the trap positioned below
the unit condensate drain connection as shown in Figure
4. Design the depth of the trap (water-seal) 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.
Figure 3: Vertical Sound Attenuation
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.
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.

Horizontal Installation
Horizontal Unit Location
Units are not designed for outdoor installation. Locate
the unit in an INDOOR area that allows enough space for
service personnel to perform typical maintenance or repairs
without removing unit from the ceiling. Horizontal units
are typically installed above a false ceiling or in a ceiling
plenum. Never install units in areas subject to freezing or
where humidity levels could cause cabinet condensation
(such as unconditioned spaces subject to 100% outside air).
Consideration should be given to access for easy removal of
the filter and access panels. Provide sufficient room to make
water, electrical, and duct connection(s).
If the unit is located in a confined space, such as a closet,
provisions must be made for return air to freely enter the space
by means of a louvered door, etc. Any access panel screws
that would be difficult to remove after the unit is installed
should be removed prior to setting the unit. Refer to Figures 7a
and 7b for an illustration of a typical installation. Refer to unit
specifications catalog for dimensional data.
Conform to the following guidelines when selecting
unit location:
1. Provide a hinged access door in concealed-spline or
plaster ceilings. Provide removable ceiling tiles in T-bar
or lay-in ceilings. Refer to horizontal unit dimensions for
specific series and model in unit specifications catalog.
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 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.
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.

Water Connection Installation
Tranquility® 22 Digital (TZ) units are offered with a standard
internal variable water flow control.
The three possible alternatives are:
1) Internal Flow Controller - For Closed
Loop Applications
Primarily for use on closed-loop applications with a
single unit. 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.
2) Internal Modulating, Motorized Valve - For Open
Loop Applications
Primarily for open loop/ground water applications. With
this factory-installed option, the unit is built with an
internal motorized modulating valve, which is controlled
by the DXM2 control board based on the difference in
entering and leaving water temperatures.
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 leak-free seal without the need for thread sealing tape or
joint compound. Insure 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
3) Internal Modulating Motorized Valve – For Closed
Loop Applications
Primarily for use on multi-unit closed loop applications
with a central variable speed pump. With this factoryinstalled option, the unit includes a low pressure drop
motorized modulating valve that is controlled by the
DXM2 microprocessor control based on the difference in
the entering and leaving water temperatures.

Ground-Loop Heat Pump Applications
With industry leading ‘plug and play’ options for a one-unit
ground loop system, a TZ unit with Internal Flow Controller
(IFC) would be used.
Pre-Installation
Prior to installation, locate and mark all existing underground
utilities, piping, etc. Install loops for new construction before
sidewalks, patios, driveways, and other construction has
begun. During construction, accurately mark all ground loop
piping on the plot plan as an aid in avoiding potential future
damage to the installation.
Piping Installation
The typical closed loop ground source system is shown in
Figure 12a. All earth loop piping materials should be limited
to polyethylene fusion only for in-ground sections of the
loop. Galvanized or steel fittings should not be used at any
time due to their tendency to corrode. All plastic to metal
threaded fittings should be avoided due to their potential to
leak in earth coupled applications. A flanged fitting should be
substituted. Earth loop temperatures can range between
25 and 110°F [-4 to 43°C]. Flow rates between 2.25 and 3
gpm per ton [2.41 to 3.23 l/m per kW] of cooling capacity is
recommended in these applications.
Test individual horizontal loop circuits before backfilling.
Test vertical U-bends and pond loop assemblies prior to

Flushing the Earth Loop
Once piping is completed between the unit and the ground
loop, final purging and charging of the loop is needed.
Tranquility 22 units with Internal Flow Controller option
are also provided with an expansion tank to help maintain
positive pressure on the complete system through all
seasons.
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 tables 15a through 15d for flow rate required to
attain 2fps [0.6 m/s]. The steps below must be followed for
proper flushing.
Loop Fill
Fill loop (valve position B) with water from a garden hose
through flush cart before using flush cart pump to ensure
an even fill and increase flushing speed. When water
consistently returns back to the flush reservoir, switch to
valve position A.
Isolate expansion tank for flushing procedure. During
dead heading of flush cart pump, isolation will prevent
compression of bladder in the expansion tank and flush cart
fluid level dropping below available capacity.
WARNING!
WARNING! Disconnect electrical power source to prevent
injury or death from electrical shock.

Unit fill valves should be switched while flush cart is
pumping to fill the unit heat exchanger and hose kit. The
position should be maintained until water consistently is
returned into the flush reservoir.
Loop Flush
Switch to valve position B. 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
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. When the fluid level is dropping less than 3/8” in a 10”
[25.4 cm] diameter tank, the flow can be reversed.
In
Switch valves to position C to flush the unit. Flush through
the unit until all air pockets have been removed.

Move valves to position D. By switching both valves to this

exchanger. Finally, the dead head test should be checked
again for an indication of air in the loop. Fluid level drop

be added during this part of the flushing procedure; see

Pressures can easily be “topped off” with the use of a

50 and 75 psi [345 to 517 kPa] upon completion of the
service call, pressures should be sufficient for all seasons.

Pressurize and Operate
As shown in Figure 14e, 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. 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 E.
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
the flush cart from the Internal Flow Controller. Install Flow
Controller caps to ensure that any condensation/leakage
remains contained within the Flow Controller package. If
water pressure is too low to pressurize the loop to between
50 and 75 psi [345 to 517 kPa], use a hydraulic pump to
pressure the loop through the P/T port, being careful to
bleed any air before introducing any fluid through the P/T
port (Some weed sprayers works well as hydraulic pumps).

Antifreeze Characteristics
Selection of the antifreeze solution for closed loop earth
coupled systems requires the consideration of many
important factors which have long-term implications on the
performance and life of the equipment. Each area of concern
leads to a different “best choice” of antifreeze. The fact is
that there is no “ideal” antifreeze and any choice will require
compromises in one area or another. Some of the factors
to consider are safety, thermal performance, corrosiveness,
local codes, stability, convenience, and cost.

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 using Table 1.
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.
WARNING!
Specific Gravity
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. For example, if 30°F [-1°C] is the
minimum expected entering loop temperature, the leaving
loop temperature would be approximately 22 to 25°F [-5.5
to -3.9°C] and freeze protection should be at 15°F [-9.5°C].
Calculations are as follows:
30°F - 15°F = 15°F [-1°C - 8.5°C = -9.5°C]

* Must not be denatured with any petroleum based product
Methanol - Methanol or wood alcohol is considered toxic in
any form, has good heat transfer, low to mid price, flammable
in concentrations greater than 25%, non-corrosive, and low
viscosity. Methanol has delivered outstanding performance in
earth loops for over 20 years. Its only drawbacks are toxicity
and flammability. Although methanol enjoys widespread
consumer use as a windshield washer fluid in even higher
concentrations, some local codes may limit its use in earth
loops. To increase safety, a premixed form should be used on
the jobsite to increase the safety factor. Pure methanol can be
purchased from any chemical supplier.
Ethanol - Ethanol or grain alcohol exhibits good heat
transfer (slightly less than methanol), higher price, and is
flammable in concentrations greater than 10%. Ethanol
is generally non-corrosive and has medium viscosity.
Ethanol in its pure form is considered nontoxic and shows
promise as a geothermal heat transfer fluid. However the
U.S. Bureau of Alcohol, Tobacco, and Firearms (ATF) limit
its distribution. All non-beverage ethanol is required to be
denatured and rendered unfit to drink. Generally this is done
by adding a small percentage of toxic substances such
as methanol, benzene, or gasoline as a denaturant. Many
of these denaturants are difficult to identify by the casual
user and many are not compatible with polyethylene pipe.
Only denatured ethanol can be purchased for commercial
use. The use of ethanol is not recommended because of
the unknown denaturants included in the solution, and their
possible toxicity and damage resulting to polyethylene
piping systems. Denaturing agents that are petroleum based
can damage polyethylene pipe.
Ethylene glycol - Generally non-corrosive, expensive,
medium heat transfer, considered toxic. Its toxicity has
prevented its widespread use in the ground source industry
in spite of its widespread use in traditional water-source
heat pump applications. Ethylene glycol is not currently
recommended as ground-source antifreeze.
present in other mixtures) from reacting with local water and
‘coming out’ of solution to form slime type coatings inside heat
exchangers and thus hinder heat transfer. If propylene glycol
must be used (e.g. code requirements), careful consideration
of loop Reynolds numbers, pump selection and pressure drop
must be considered.
Potassium acetate - Nontoxic, good heat transfer, high price,
non-corrosive with added inhibitors, low viscosity. Due to its
low surface tension, Potassium Acetate has been known to
leak through mechanical fittings and certain thread sealants.
A variant of the salt family, it can be extremely corrosive when
exposed to air. Potassium Acetate is not recommended in
ground-source applications due to the leaking and (ultimately)
corrosion problems associated with it.
Contact the Application Support Department 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. Most washer fluid contains chemicals that will
cause foaming.
CAUTION!
CAUTION! Always obtain MSDS safety sheets for all
chemicals used in ground loop applications including
chemicals used as antifreeze.
Propylene glycol - Nontoxic, non-corrosive, expensive, hard to
handle when cold, poorest heat transfer, has formed “slimetype” coatings inside pipe. Poor heat transfer has required
its removal in some systems. Propylene glycol is acceptable
in systems anticipating loops temperatures no colder than
40°F [4.4°C]. These systems typically use antifreeze because
of low ambient conditions (outside plumbing or cooling
tower, etc.). When loop temperatures are below 40°F [4.4°C],
the fluid becomes very difficult to pump and heat transfer
characteristics suffer greatly. Only food grade propylene glycol
is recommended to prevent the corrosion inhibitors (often

Ground Loop Heat Pump Applications
Antifreeze Charging
It his highly recommended to utilize premixed antifreeze fluid
where possible to alleviate many installation problems and
extra labor.
The following procedure is based upon pure methanol and can
be implemented during the Full Flush procedure with three
way valves in the Figure 14d - Valve Position D. If a premixed
methanol 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 methanol 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 1.
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 and Flow Controller to ambient conditions.
4) Isolate unit and prepare to flush only through loop.
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).
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.
WARNING!
WARNING! Always dilute alcohols with water (at least
50% solution) before using. Alcohol fumes are flammable
and can cause serious injury or death if not handled
properly.
7) Close the flush cart return valve; immediately thereafter,
close the flush cart supply valve, shut off the flush cart
leaving a positive pressure in the loop of approximately
50-75 psi [345-517 kPa]. Refer to Figure 14e for more
details.
Low Water Temperature Cutout Setting - DXM2 Control
When antifreeze is selected, the LT1 jumper (JW3) should
be clipped to select the low temperature (antifreeze 10°F
[-12.2°C]) set point and avoid nuisance faults (see “Low
Water Temperature Cutout Selection” in this manual).

Pressure/Water Ports
The pressure ports built in to the unit are provided as a
means of measuring flow and temperature. The water
flow through the unit can be checked by measuring the
incoming water pressure at the supply water pressure port
and subtracting the leaving water pressure at the return
water pressure port. Comparing the pressure differential
to the pressure drop table/flow rate in the unit installation
manual will determine the flow rate through the unit. Ground
loop required flow rates are 2.25 to 3 U.S. gpm per nominal
cooling ton [2.41 to 3.23 l/m per kW]. Note: Minimum flow for
units is 2.25 gpm per ton [2.41 l/m per kW].
range from approximately 15-50 psi [103-345 kPa]. At the
start-up of a system, the earth loops should have a (static)
holding pressure of approximately 50-75 psi [345-517 kPa].
Maximum operating pressure should never exceed 100 psi
[689 kPa] under any circumstance.
NOTICE: It is recommended to run the unit in the cooling,
then heating mode for 15-20 minutes each to ‘temper’ the
fluid temperature and prepare it for pressurization. This
procedure helps prevent the periodic “flat” loop condition of
no pressure.
After pressurization, be sure the loop Flow Controller
provides adequate flow through the unit by checking
pressure drop across the heat exchanger and comparing it
to the pressure drop/flow rate tables in the unit Installation
manual. The Internal Variable Speed Flow Controller pump
performance is shown in Chart 2.
Start-Up of Flow Controller
1) Check to make sure that the loop and unit isolation
valves (if applicable) are completely open and the flush
ports are closed and sealed.
2) Check and record the earth loop pressure via the
pressure ports on the front of the unit. Loop Pressure =
In_______ Out_______.
3) Check and record the flow rate.
Flow Rate = _______gpm.
4) Check performance of unit. Refer to unit installation
manual. Replace all caps to prevent pressure loss.
When replacing a pump, isolate the pump from loop as in
Figure 16. Always disable power to the pumps and remove
pump power wiring if needed. The following five steps
outline the detailed procedure.
Example: Model TZ 036 has a 50°F entering water
temperature (EWT) and 50 psi entering water pressure
(EWP). The leaving water pressure (LWP) is 37 psi. Pressure
Drop (PD) = EWP - LWP = 50 - 37 = 13 psi. In the unit
Installation manual, a 13 PSI pressure drop is equivalent to
9 GPM at 50°F EWT on the chart. More flow will not hurt
the performance. However, insufficient flow can significantly
reduce capacity and possibly even cause damage to the
heat pump in extreme conditions. A digital pressure gauge is
needed for the pressure ports on the front of the unit, which
are available in the residential price list.
Earth Loop Pressure
The earth loop must have a slight positive pressure to
operate the pumps [>3 psi, >20.7 kPa]. The system pressure
will drop as the earth loop pipe relaxes, and will fluctuate as
the fluid temperature changes. Typical earth loop pressures

Pump Replacement Procedure
WARNING!
WARNING! Disconnect electrical power source to prevent
injury or death from electrical shock.
1. Close valves as shown in Figure 16.
2. Place rag under pump to collect loop fluid.
3. Remove 4 Allen head mounting bolts and lift off pump
motor housing.
4. Replace with new pump insuring no foreign material has
been introduced, and evenly install the four Allen head
mounting bolts.
5. Place garden hose supply and return on flush ports as
shown in Figure 16 and open valves to flush through
the unit portion of loop. When water flows clear, close
return side to pressurize. Then, close the supply side
valve. Finally, close 3-way valves to operation position as
shown in Figure 14e. In situations where this procedure
may not be feasible, the loop can also be re-flushed
using the complete flushing procedure outlined for
installation.
NOTICE: Remember this procedure will dilute the antifreeze
mixture by a couple of gallons [7-8 liters]. If performed more
than twice on any earth loop, the antifreeze concentration
should be checked with a hydrometer and antifreeze added
as needed.

to allow flow through the coax via the boiler drains without
allowing flow into the piping system. Pressure plugs built
into unit should be used to measure pressure drop. Water
temperature can be viewed on the communicating thermostat.
Piping materials should be limited to copper or PVC SCH80.
Note: Due to the pressure and temperature extremes, PVC
SCH40 is not recommended.
Water quantity should be plentiful and of good quality.
Consult table 3 for water quality requirements. The unit
can be ordered with either a copper or cupro-nickel water
heat exchanger. Consult table 3 to determine which heat
exchanger to use. Copper is recommended for closed loop
systems and open loop ground water systems that are not
high in mineral content or corrosiveness. In installations
anticipating heavy scale formation or in brackish water, a
cupro-nickel heat exchanger is recommended. In ground
water situations where scaling could be heavy or where

biological growth such as iron bacteria will be present, an
open loop system is not recommended. Heat exchanger
coils may over time lose heat exchange capabilities due to
build up of mineral deposits. Heat exchangers must only
be serviced by a qualified technician, as acid and special
pumping equipment is required. Desuperheater coils can
likewise become scaled and possibly plugged. In areas with
extremely hard water, the owner should be informed that the
heat exchanger may require occasional acid flushing. In some
cases, the desuperheater option should not be recommended
due to hard water conditions and additional maintenance
required.
Water Quality Standards
Table 3 should be consulted for water quality requirements.
Scaling potential should be assessed using the pH/
Calcium hardness method. If the pH <7.5 and the Calcium
hardness is less than 100 ppm, scaling potential is low. If
this method yields numbers out of range of those listed, the
Ryznar Stability and Langelier Saturation indecies should be
calculated. Use the appropriate scaling surface temperature
for the application, 150°F [66°C] for direct use (well water/
open loop) and DHW (desuperheater); 90°F [32°F] for
indirect use. A monitoring plan should be implemented in
these probable scaling situations. Other water quality issues
such as iron fouling, corrosion prevention and erosion and
clogging should be referenced in Table 3.
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.

Ground-Water Heat Pump Applications
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.
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.
Internal Motorized Modulating Valve
TZ series units are available with an internal motorized
modulating water valve for open loop applications. The
internal motorized modulating valve replaces the water control
valve and flow regulator used in earlier non Plug and Play
units. The valve (ball valve) regulates the flow using ∆T of the
system. Pressure drop through the unit heat exchanger can
be measured using two pressure gauges on the unit’s two
pressure ports. Entering and leaving water temperature is read
on the communicating thermostat / configuration tool.
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” 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
excess heat energy from the heat pump 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. Figure 18 shows a typical example of HWG water
piping connections on a unit with built-in circulating pump.
This piping layout reduces scaling potential.
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 generated 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.
Electric water heaters are recommended. If a gas, propane,
or oil water heater is used, a second preheat tank must be
installed (Figure 19). If the electric water heater has only a
single center element, the dual tank system is recommended
to insure a usable entering water temperature for the HWG.
Typically a single tank of at least 52 gallons (235 liters) is
used to limit installation costs and space. However, a dual
tank, as shown in Figure 19, is the most efficient system,
providing 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.

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.
This example ignored standby losses of the tank. When
those losses are considered the additional savings are even
greater.

WARNING!
WARNING! UNDER NO CIRCUMSTANCES SHOULD
THE SENSORS BE DISCONNECTED OR REMOVED.
FULL LOAD CONDITIONS CAN DRIVE HOT
WATER TANK TEMPERATURES FAR ABOVE SAFE
TEMPERATURE LEVELS IF SENSORS DISCONNECTED
OR REMOVED.
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. The DXM2 microprocessor control
Includes 3 DIP switches, S3–2 (HWG PUMP TEST), S3–3
(HWG TEMP), and S3–4 (HWG STATUS).
S3–2 HWG PUMP TEST. When this switch is in the “ON”
position, the HWG pump is forced to operate even if there is
no call for the HWG. This mode may be beneficial to assist
in purging the system of air during Initial start up. When
S3–2 is in the “OFF” position, the HWG will operate normally.
This switch is shipped from the factory in the “OFF” (normal)
position. NOTE; If left in the “On” position for 5 minutes, the
pump control will revert to normal operation.
S3–3 HWG TEMP. The control setpoint of the HWG can be
set to either of two temperatures, 125°F [52°C] or 150°F
[66°C]. When S3–3 is in the “ON” position the HWG setpoint
is 150°F. When S3–3 is in the “OFF” position the HWG
setpoint is 125°F. This switch is shipped from the factory in
the “OFF” (125°F) position.
S3–4 HWG STATUS. This switch controls operation of
the HWG. When S3-4 is in the “OFF” position the HWG is
disabled and will not operate. When S3–4 is in the “ON”
position the HWG is in the enabled mode and will operate
normally. This switch is shipped from the factory in the
“OFF” (disabled) position. CAUTION: DO NOT PLACE THIS
SWITCH IN THE ENABLED POSITION UNITL THE HWG
PIPING IS CONNECTED, FILLED WITH WATER, AND
PURGED OR PUMP DAMAGE WILL OCCUR.
If the control has detected a HWG fault, the DXM2 status
LED will flash a numeric fault code as follows:
High Water Temperature (>160ºF)
Hot Water Sensor Fault
Compressor Discharge Sensor Fault
5 flashes
6 flashes
6 flashes
Fault code flashes have a duration of 0.3 seconds with
a 10 second pause between fault codes. For example, a
“Compressor Discharge sensor fault” will be six flashes 0.3
seconds long, then a 10 second pause, then six flashes
again, etc.
WARNING!
WARNING! USING A 150°F SETPOINT ON THE
HWG WILL RESULT IN WATER TEMPERATURES
SUFFICIENT TO CAUSE SEVERE PHYSICAL INJURY
IN THE FORM OF SCALDING OR BURNS, EVEN
WHEN THE HOT WATER TANK TEMPERATURE

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
connect the pump wiring until “Initial Start-Up” section,
below. Powering the pump before all installation steps are
completed may 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 5/8” [16mm] O.D. copper, route and install
the water piping and valves as shown in Figures 18 or
19. 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 Figures 18 and 19) 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.
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 (Fig 19).
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.
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.

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 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.

CAUTION!
CAUTION! Use only copper conductors for field installed
electrical wiring. Unit terminals are not designed to accept
other types of conductors.
Electrical - Line Voltage
All field installed wiring, including electrical ground, must
comply with the National Electrical Code as well as all
applicable local codes. Refer to the unit electrical data for
fuse sizes. Consult wiring diagram for field connections that
must be made by the installing (or electrical) contractor.
All final electrical connections must be made with a length of
flexible conduit to minimize vibration and sound transmission
to the building.
General Line Voltage Wiring
Be sure the available power is the same voltage and phase
shown on the unit serial plate. Line and low voltage wiring
must be done in accordance with local codes or the National
Electric Code, whichever is applicable.
Power Connection
Line voltage connection is made by connecting the incoming
line voltage wires to the “L” side of the contactor as shown in
Figure 21. Consult Tables 5a and 5b for correct fuse size.
208 Volt Operation
All residential 208-230 Volt units are factory wired for 230
Volt operation. The transformer may be switched to the 208V
tap as illustrated on the wiring diagram by switching the red
(208V) and the orange (230V) wires at the contactor terminal.

Special Note for AHRI Testing: To achieve rated airflow
for AHRI testing purposes, it is necessary to change the
CFM settings to rated airflow. When the heat pump has
experienced less than 100 operational hours and the coil has
not had sufficient time to be “seasoned”, it is necessary to
clean the coil with a mild surfactant such as Calgon to remove
the oils left by manufacturing processes and enable the
condensate to properly “sheet” off of the coil.

JW3-LT1 jumper should be clipped
for low temperature (antifreeze) operation
Accessory Connections
A terminal paralleling the compressor contactor coil
has been provided on the DXM2 control. Terminal “A” is
designed to control accessory devices, such as water
valves. Note: This terminal should be used only with 24 Volt
signals and not line voltage. Terminal “A” is energized with
the compressor contactor. See Figure 24 or the specific unit
wiring diagram for details.
Low Voltage Field Wiring
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 sensing temperature associated
with thermistor LT1. Note that the LT1 thermistor is located on
the refrigerant line between the coaxial heat exchanger and
expansion device (TXV). 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.
Figure 24: Accessory Wiring
The factory setting for LT1 is for systems using water (30°F
[-1.1°C] refrigerant temperature). In low water temperature
(extended range) applications with antifreeze (most ground
loops), jumper JW3 should be clipped as shown in Figure
23 to change the setting to 10°F [-12.2°C] refrigerant
temperature, a more suitable temperature when using
an antifreeze solution. All residential units include water/
refrigerant circuit insulation to prevent internal condensation,
which is required when operating with entering water
temperatures below 59°F [15°C].

Electrical - Thermostat Wiring
Thermostat Installation
The thermostat should be located on an interior wall in a
larger room, away from supply duct drafts. DO NOT locate
the thermostat in areas subject to sunlight, drafts or on
external walls. The wire access hole behind the thermostat
may in certain cases need to be sealed to prevent erroneous
temperature measurement. Position the thermostat back
plate against the wall so that it appears level and so the
thermostat wires protrude through the middle of the back
plate. Mark the position of the back plate mounting holes
and drill holes with a 3/16” (5mm) bit. Install supplied
anchors and secure plate to the wall. Thermostat wire must
be 18 AWG wire. Wire the appropriate thermostat as shown
in Figures 25a and 25b 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.
CAUTION!
CAUTION! Refrigerant pressure activated water regulating
valves should never be used with ClimateMaster
equipment.

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, a communicating or conventional
multi-stage thermostat should be used (2-stage heat/2-stage
cool or 3-stage heat/2-stage cool).
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.
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.
Airflow levels are selected using the configuration menus
of a communicating thermostat or diagnostic tool. 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 upper and lower limits shown on Table
6.The blower operating modes include:
• First Stage Cooling (Y1 & O)
• Second Stage Cooling (Y1, Y2, & O)
• First Stage Cooling with Dehumidification
(Y1, O, & Dehumid)
• Second Stage Cooling with Dehumidification
(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)
Dehumidification Mode Settings: The dehumidification mode
settings provide field selection of humidity control. When
operating in the normal mode, the cooling airflow settings are
determined by the cooling settings. When dehumidification
is enabled the appropriate dehumidification airflow is used in
cooling to increase the moisture removal of the heat pump.
The dehumidification mode can be enabled in two ways.
1. Constant Dehumidification Mode: When the constant
dehumidification mode is selected (S1–5 on the
DXM2 control), the ECM motor will operate using the
dehumidification airflow slections while operating in
cooling to improve latent capacity. Heating airflow is
not affected.
2. Automatic (Humidistat-controlled) Dehumidification
Mode: When the automatic dehumidification mode
is selected (S2–7 on the DXM2 control) AND a
dehumidistat is connected to the H terminal, the
dehumidification airflows will be used in cooling
only when the dehumidistat senses that additional
dehumidification is required. Heating airflow is not
affected.
The ECM motor includes “soft start” and “ramp down”
features. The soft start feature is a gentle increase of motor

DXM2 Controls
DXM2 Control - For detailed control information, see DXM2
Application, Operation and Maintenance (AOM) manual (part
# 97B0003N15).
Field Selectable Inputs - Test mode: Test mode allows
the service technician to check the operation of the control
in a timely manner. By momentarily pressing the TEST
pushbutton, the DXM2 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 display will change,
either flashing rapidly to indicate the control is in the test
mode, or displaying a numeric flash code representing the
current airflow if an ECM blower is connected and operating.
For diagnostic ease at conventional thermostats, the alarm
relay will also cycle during test mode. The alarm relay will
cycle on and off similar to the fault LED to indicate a code
representing the last fault, at the thermostat. Test mode can
be exited by pressing the TEST pushbutton for 3 seconds.
Retry Mode: If the control is attempting a retry of a fault,
the fault LED will slow flash (slow flash = one flash every 2
seconds) to indicate the control is in the process of retrying.
Field Configuration Options - Note: In the following field
configuration options, jumper wires should be clipped ONLY
when power is removed from the DXM2 control.
Water coil low temperature limit setting: Jumper 3 (JW3LT1 Low Temp) provides field selection of temperature limit
setting for LT1 of 30°F or 10°F [-1°F or -12°C] (refrigerant
temperature).
Not Clipped = 30°F [-1°C]. Clipped = 10°F [-12°C].
Alarm relay setting: Jumper 1 (JW1-AL2 Dry) provides field
selection of the alarm relay terminal AL2 to be jumpered to
24VAC or to be a dry contact (no connection).
Not Clipped = AL2 connected to R. Clipped = AL2 dry
contact (no connection).
DIP Switches - Note: In the following field configuration
options, DIP switches should only be changed when power
is removed from the DXM2 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 DXM2 controls are being
used) or with master/slave applications. In master/slave
applications, each compressor and fan will stage according
to its appropriate DIP 1.2 setting. If set to stage 2, the
compressor will have a 3 second on-delay before energizing
during a Stage 2 demand. Also, if set for stage 2, the alarm
relay will NOT cycle during test mode.
On = Stage 1. Off = Stage 2.
1.3 - Thermostat type (heat pump or heat/cool): DIP 1.3
provides selection of thermostat type. Heat pump or heat/
cool thermostats can be selected. When in heat/cool mode,
Y1 is the input call for cooling stage 1; Y2 is 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 LT1 is above the temperature
specified by the setting of DIP 1.8. Below DIP 1.8 setting, the
compressor is not used and the control goes into emergency
heat mode, staging on EH1 and EH2 to provide heating.
On = normal. Off = Boilerless operation.
1.8 - Boilerless changeover temperature: DIP 1.8 provides
selection of boilerless changeover temperature setpoint.
Note that the LT1 thermistor is sensing refrigerant
temperature between the coaxial heat exchanger and the
expansion device (TXV). Therefore, the 50°F [10°C] setting is
not 50°F [10°C] water, but approximately 60°F [16°C] EWT.
On = 50°F [10°C]. Off = 40°F [16°C].
DIP Package #2 (S2) - DIP Package #2 has 8 switches and
provides the following setup selections:
2.1 - Accessory1 relay personality: DIP 2.1 provides
selection of ACC1 relay personality (relay operation/
characteristics). See Table 7a for description of functionality.
2.2 - Accessory1 relay personality: DIP 2.2 provides
selection of ACC 1 relay personality (relay operation/
characteristics). See Table 7a for description of functionality.

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.

Thermostat Compatibility – Most heat pump and heat/cool
thermostats can be used with the DXM2, as well as ClimateMaster communicating thermostats.
Anticipation Leakage Current – Maximum leakage current for “Y1” is 50 mA and for “W” is 20mA. Triacs can be
used if leakage current is less than above. Thermostats with
anticipators can be used if anticipation current is less than
that specified above.
Thermostat Signals • “Y1, Y2, W1, O” and “G” have a 1 second recognition time
when being activated or being removed.
• “R” and “C” are from the transformer.
• “AL1” and “AL2” originate from the Alarm Relay.
• “A+” and “B-” are for a communicating thermostat.
• “A” is paralleled with the compressor output for use with
well water solenoid valves.

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, voltage range A.
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 9a and
9b.
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 speed selection and
compare to design requirements.
Condensate line: Verify that condensate trap is installed
and pitched.
HWG pump is disconnected unless piping is completed
and air has been purged from the system.
Water flow balancing: Record inlet and outlet water
temperatures for each heat pump upon startup. This
check can eliminate nuisance trip outs and high velocity
water flow that could erode heat exchangers.
Unit air coil and filters: 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
longevity of hoses and fittings (see Table 3).
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
40
operate in the proper sequence.
Low water temperature cutout: Verify that low water
temperature cut-out controls are set properly
(LT1 - JW3).
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. Balance air flow at registers.
3. Adjust all valves to their full open position. Turn on the
line power to all heat pump units.
4. Room temperature should be within the minimummaximum ranges of Table 9b. During start-up 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) water
temperature. When any one of these factors is at a
minimum or maximum level, the other factor must be at
normal level to insure proper unit operation.
a. Adjust the unit thermostat to the warmest setting.
Place the thermostat mode switch in the “COOL”
position. Slowly reduce thermostat setting until the
compressor activates.
b. Check for cool air delivery at the unit grille within a
few minutes after the unit has begun to operate.
Note: Units have a five minute time delay in the
control circuit that can be bypassed on the DXM2
control board as shown in Figure 26. See controls
description for details.
c. Verify that the compressor is on and that the water
flow rate is correct by measuring pressure drop
through the heat exchanger using the pressure ports
and comparing to Table 10.
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

Unit Start-Up Procedure
to provide a water seal.
e. Refer to Table 11. Check the temperature of both
entering and leaving water. If temperature is within
range, proceed with the test. If temperature is
outside of the operating range, check refrigerant
pressures and compare to Table 13. Verify correct
water flow by comparing unit pressure drop across
the heat exchanger versus the data in Table 10. Heat
of rejection (HR) can be calculated and compared to
catalog data capacity pages. The formula for HR for
systems with water is as follows:
HR = TD x GPM x 500, where TD is the temperature
difference between the entering and leaving water,
and GPM is the flow rate in U.S. GPM, determined
by comparing the pressure drop across the heat
exchanger to Table 10.
f. Check air temperature drop across the air coil when
compressor is operating. Air temperature drop should
be between 15°F and 25°F [8°C and 14°C].
g. Turn thermostat to “OFF” position. A hissing noise
indicates proper functioning of the reversing valve.
7. Allow five (5) minutes between tests for pressure to
equalize before beginning heating test.
a. Adjust the thermostat to the lowest setting. Place the
thermostat mode switch in the “HEAT” position.
b. Slowly raise the thermostat to a higher temperature
until the compressor activates.
c. Check for warm air delivery within a few minutes after
the unit has begun to operate.
d. Refer to Table 11. Check the temperature of both
entering and leaving water. If temperature is within
range, proceed with the test. If temperature is outside
of the operating range, check refrigerant pressures
and compare to Table 13. Verify correct water flow
by comparing unit pressure drop across the heat
exchanger versus the data in Table 10. Heat of
extraction (HE) can be calculated and compared to
submittal data capacity pages. The formula for HE
for systems with water is as follows:
HE = TD x GPM x 500 for water (485 for antifreeze),
where TD is the temperature difference between the
entering and leaving water, and GPM is the flow rate
in U.S. GPM, determined by comparing the pressure
drop across the heat exchanger to Table 10.
e. Check air temperature rise across the air coil when
compressor is operating. Air temperature rise should
be between 20°F and 30°F [11°C and 17°C].
f. Check for vibration, noise, and water leaks.
8. If unit fails to operate, perform troubleshooting analysis
(see troubleshooting section). If the check described
fails to reveal the problem and the unit still does not
operate, contact a trained service technician to insure
proper diagnosis and repair of the equipment.
9. When testing is complete, set system to maintain
desired comfort level.
10. BE CERTAIN TO FILL OUT AND RETURN ALL
WARRANTY REGISTRATION PAPERWORK.
Note: If performance during any mode appears abnormal,
refer to the DXM2 section or troubleshooting section of this
manual. To obtain maximum performance, the air coil should
be cleaned before start-up. A 10% solution of dishwasher
detergent and water is recommended.
WARNING!
WARNING! When the disconnect switch is closed, high
voltage is present in some areas of the electrical panel.
Exercise caution when working with energized equipment.
CAUTION!
CAUTION! Verify that ALL water 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.

Example:
At 50°F EWT (Entering Water Temperature) and 1.5 gpm/
ton, a 3 ton unit has a HE of 22,500 Btuh. To calculate LWT,
rearrange the formula for HE as follows:
HE = TD x GPM x 500, where HE = Heat of Extraction (Btuh);
TD = temperature difference (EWT - LWT) and GPM = U.S.
Gallons per Minute.

TD = HE/(GPM x 500)
TD = 22,500/(4.5 x 500)
TD = 10°F
LWT = EWT - TD
LWT = 50 - 10 = 40°F
In this example, as long as the EWT does not fall below 50°F, the system will operate as designed. For EWTs below 50°F,
higher flow rates will be required (open loop systems, for example, require at least 2 gpm/ton when EWT is below 50°F).

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. Dirty installations are typically the result
of deterioration of iron or galvanized piping or components
in the system. Open cooling towers requiring heavy chemical
treatment and mineral buildup through water use can also
contribute to higher maintenance. Should periodic coil
cleaning be necessary, use standard coil cleaning procedures,
which are compatible with both the heat exchanger material
and copper water lines. Generally, the more water flowing
through the unit, the less chance for scaling. However, flow
rates over 3 gpm per ton (3.9 l/m per kW) can produce water
(or debris) velocities that can erode the heat exchanger wall
and ultimately produce leaks.
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.
Filters
Filters must be clean to obtain maximum performance.
Filters should be inspected every month under normal
operating conditions and be replaced when necessary. Units
should never be operated without a filter.
Condensate Drain
In areas where airborne bacteria may produce a “slimy”
substance in the drain pan, it may be necessary to treat the
drain pan chemically with an algaecide approximately every
three months to minimize the problem. The condensate pan
may also need to be cleaned periodically to 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 units have lubricated fan motors. Fan motors should
never be lubricated unless obvious, dry operation
is suspected. Periodic maintenance oiling is not
recommended, as it will result in dirt accumulating in the
excess oil and cause eventual motor failure. Conduct annual
dry operation check and amperage check to insure amp
draw is no more than 10% greater than indicated on serial
plate data.
Air Coil
The air coil must be cleaned to obtain maximum
performance. Check once a year under normal operating
conditions and, if dirty, brush or vacuum clean. Care must
be taken not to damage the aluminum 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.
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.

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
8. An ice bath can be used to check the calibration of the
thermistor.
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
If a communicating thermostat or diagnostic tool is
connected to the DXM2, additional diagnostic information
and troubleshooting capabilities are available. The current
status of all DXM2 inputs can be verified, including the
current temperature readings of all temperature inputs.
With a communicating thermostat the current status of the
inputs can be accessed from the Service Information menu.
In the manual operating mode, most DXM2 outputs can
be directly controlled for system troubleshooting. With a
communicating thermostat the manual operating mode can
be accessed from the Installer menu. For more detailed
information on the advanced diagnostics of the DXM2, see
the DXM2 Application, Operation and Maintenance (AOM)
manual (part #97B0003N15).
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.
