Important Environmental Concerns
Scientific research has shown that certain man-made
chemicals can affect the earth’s naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are refrigerants
that contain Chlorine, Fluorine and Carbon (CFCs) and
those containing Hydrogen, Chlorine, Fluorine and
Carbon (HCFCs). Not all refrigerants containing these
compounds have the same potential impact to the
environment.Trane advocates the responsible handling of
all refrigerants-including industry replacements for CFCs
such as HCFCs and HFCs.
Important Responsible Refrigerant
Practices
Trane believes that responsible refrigerant practices are
important to the environment, our customers, and the air
conditioning industry. All technicians who handle
refrigerants must be certified.The Federal Clean Air Act
(Section 608) sets forth the requirements for handling,
reclaiming, recovering and recycling of certain
refrigerants and the equipment that is used in these
service procedures. In addition, some states or
municipalities may have additional requirements that
must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.
WARNING
Personal Protective Equipment (PPE)
Required!
Installing/servicing this unit could result in exposure to
electrical, mechanical and chemical hazards.
•Before installing/servicing this unit, technicians
MUST put on all PPE required for the work being
undertaken (Examples; cut resistant gloves/sleeves,
butyl gloves, safety glasses, hard hat/bump cap, fall
protection, electrical PPE and arc flash clothing).
ALWAYS refer to appropriate Material Safety Data
Sheets (MSDS)/Safety Data Sheets (SDS) and OSHA
guidelines for proper PPE.
•When working with or around hazardous chemicals,
ALWAYS refer to the appropriate MSDS/SDS and
OSHA/GHS (Global Harmonized System of
Classification and Labelling of Chemicals) guidelines
for information on allowable personal exposure
levels, proper respiratory protection and handling
instructions.
•If there is a risk of energized electrical contact, arc, or
flash, technicians MUST put on all PPE in accordance
with OSHA, NFPA 70E, or other country-specific
requirements for arc flash protection, PRIOR to
servicing the unit. NEVER PERFORM ANY

Controls
Basic 24V control is available for the GEH/V ½ -5 ton
models and the Deluxe 24V control option is available for
all unit sizes.Tracer™ ZN524, LonTalk® certified control
option is available for allunit sizes. UC400 and UC400 with
wireless comm BACnet is available in all unit sizes.
All power wiring to the equipment is made at the unit
contactor for ½- 5 ton, 1-phase units. For 3-phase units all
power wiring to the equipmentis made tothe contactor or
power block. For EXH/V070 units all power wiring to the
equipment is made to the power block. For the GEH/V 6-25
tons units all power wiring is made to the high voltage
terminal block. All low-voltage wiring is made at the unit’s
low voltage terminal board. EXH and EXV 460V units
require a neutral wire.
System Input Devices and Functions
A thermostat, zone sensor, or building automation system
is required to operate the water-source heat pump.The
flexibility of having several mode capabilities depends
upon the type of sensor and/or remote panel selected.
Troubleshooting and connection diagrams for the 24V
control systems may be locatedin the back of this manual.
All digital control troubleshooting tips and connection
diagrams are located in WSHP-PRB002-EN (ZN524).
Basic 24V Controls
Safety devices for equipment containing the basic 24V
control option include a low-pressure switch to prevent
compressor operation during low temperature or low
suction activity.The switch is set to activate at refrigerant
pressure of 40 psig to fit most applications.
A high pressure switch prevents compressor operation
during high or excessive discharge pressures exceeding
650 psig.
The lockout relay will disable the compressor on a high or
low pressure condition. For units that contain a
condensate overflow switch option, a condensate
overflow condition will also disable the compressor
through the lockout relay.The relay may be reset at the
thermostat, or by cycling power to the unit.
General alarm is accomplished through the lockout relay.
This feature will drive dry contacts only, and cannot be
used to drive field installed control inputs.Trane provides
a 3½-minute time delay for compressor control.
Deluxe 24V Controls (option)
Units containing the Deluxe 24V control design will
incorporate a microprocessor-based control board.The
Trane® microprocessor board is factory wired to a
terminal strip to provide all necessary terminals for field
connection.The deluxe board is equipped with a random
start relay, anti-short cycle timer, brown out protection,
compressor disable, condensate overflow, unit safety
control, diagnostics, and a generic relay (which may be
available for field use). See Table 65, p. 119 for diagnostic
information and Figure 59, p. 62 and Figure 60, p. 63 for
thermostat connections.
Tracer™ UC400
TheTracer™ UC400 is a BTL Listed BACnet® controller
that can operate stand- alone or within a Building
Automations system such asTracer™ SC.
Tracer ZN524 Controls (option)
The digital ZN524 controller is designed to support the ½
to 25 ton water-source heat pumps in either a standalone,
peer-to-peer with aTracer Loop Controller, or as a full
building automation (open protocol) system.
For installation, operation and diagnostics see WSHPPRB002-EN (ZN524).
Pump Module (field installed accessory)
The pump module shall consist of either a single or dual 1/
6 HP bronze pump and a brass three-way shut-off valve.
Cast iron pumps are also acceptable.The pump module
kits shall contain the necessary components for the
installation, operation and maintenance of the water
circuit of a closed-loop distributed pumping application.
WSHP-SVX01N-EN9

General Information
Waterside Economizer (Option)
Instructions for mechanical connection of the waterside
economizer to the water-source heat pump may be found
in the dimensional section of this manual.
The waterside economizer is designed to begin
economizing mode when water temperatures fall below
the field adjustable temperature of 25, 35, 45, 55 or 60°F
(for the Deluxe control option), or below the programmed
set-point (for the ZN524 control option).
When the temperature is less than the setpoint, fluid will
flow into the economizing coil, while simultaneously
halting mechanical operation of the compressor.
Mechanical cooling will continue on a call for a second
stage from the thermostat or system control. Entering
water temperature sensor is factory provided for field
installation on the entering water side of the coil.
Boilerless Control/Electric Heat (Option)
Systems that do not contain a boiler may contain a
boilerless control with electric heat.Trane® offers both a
factory mounted electric heat option, and a field mounted
duct heater option.
If the ½-5 ton GEH, GEV and EXH/V070 unit incorporates
the factory mounted option, the unit will ship from the
factory with an internally mounted nichrome open wire
heating element, designed to start-up electric heat as the
systems primary heat in the event entering water
temperature falls below 55°F. Once the entering water
temperature rises above 60°F, the boilerless controller
returns the unit to normal compressor heating operation,
and locks out the electric heater.
For units comprised of the field installed duct heater
option, the unit will ship from the factory with controls
available to interface with the field provided electric heat
selection.
Note: For geothermal applications, the boilerless
controller has an adjustable setting of 25, 35, 45, 55,
and 60 degrees.
Supplemental or Boilerless Electric Heat
(option)
The GEH/V 6-25 ton models which contain boilerless
control electric heat or supplemental electric heat will
contain the controls interface ONLY for field provided
electric heat selection.The heater for this model shall be
external to the equipment by the contractor for ease of
installation. All power connections for the electric heater
will be completely separate from theunit for field supplied
electric heat.
Note: When the unit has boilerless control, the electric
heat is not used as supplemental electric heat, but
as a primary heat.
Hot Gas Reheat (option)
With the reheat option, the return-air from the space is
conditioned by the air-to-refrigerant coil, then reheated by
the reheat coil to control not only the space temperature,
but to also reduce the relative humidityof the space. When
operating in the reheat mode (meaning the sensible
temperature has been met in the space), the humidistat
signals the reheat relay coil to energize, allowing the high
pressure refrigerant gas to flow from the compressor
through the reheat valve, into the reversing valve, or
reheat coil.
A switching relay has been provided for the reheat
application to adjust the blower motor from normal
operation to low speed when the hot gas reheat is
energized (for ½ -5 ton and EXH/V070 equipment only).
Note: A high static blower motor is required to support
the hot gas reheat option for the GEH/V ½ -5 ton.
Note: Units containing the hot gas reheat option should
not be used as a make-up air unit.
2 Speed Blower Motor (option)
The 6-25 ton GEH/V models have indoor blowers that are
available with 2 speed motors, selectable in the model
number (Digit 12, drive packages one to nine). High speed
airflow matches the single speed motor airflow,
referenced in the Fan Performance tables. Low fan speed
airflow is approximately 50% of high fan speed airflow.
The 6-25 ton GEH/V two-speed blower motors are
available with the following options: Deluxe24V or UC400
controls, Heat Pump (HP) or HP w/Hot Gas Reheat or HP w/
Waterside Economizer. Not available with Boilerless or
Product contains fiberglass wool. Disturbing the
insulation in this product during installation,
maintenance or repair will expose you to airborne
particles of glass wool fibers and ceramic fibers known
to the state of California to cause cancer through
inhalation. Glass wool fibers may also cause
respiratory, skin or eye irritation.

2. Access to the unit for service purposes should be provided at installation. Horizontal units require an 18 in. (457 mm) surround clear
mechanical and electrical equipment to enable panel removal from the unit for service/maintenance ability. NEC requires 36 in. clearance on the
control panel side of the unit. Some local codes require a greater service clearance. Check all code requirements prior to unit installations. Installer is
responsible for following all local and NEC code requirements.
3. Equipment containing a same-side supply/return combination requires a 3 in. (229 mm) clearance on one side. Access to the TXV may not be possible
with this 3 in. (229 mm) clearance.

1. All dimensions are in inches followed by millimeters in parenthesis.
2. Access to the unit for service purposes should be provided at installation. Horizontal units require an 18 in. (457 mm) surround clear
mechanical and electrical equipment to enable panel removal from the unit for service/maintenance ability. NEC requires 36 in. clearance on the
control panel side of the unit. Some local codes require a greater service clearance. Check all code requirements prior to unit installations. Installer is
responsible for following all local and NEC code requirements.
3. Equipment containing a same-side supply/return combination requires a 3 in. (229 mm) clearance on one side. Access to the TXV may not be possible
with this 3 in. (229 mm) clearance.
4. If hot gas reheat is specified for a size 018, 024, the actual cabinet size increases to an 036 cabinet.

1. All dimensions are in inches followed by millimeters in parenthesis.
2. Access to the unit for service purposes should be provided at installation. Vertical units require an 24 in. (610 mm) surround clearance from other
mechanical and electrical equipment to enable panel removal from the unit for service/maintenance ability. NEC requires 36 in. clearance on the
control panel side of the unit. Some local codes require a greater service clearance. Check all code requirements prior to unit installations. Installer is
responsible for following all local and NEC code requirements.
3. Units in a free return application will require more than a 1 in. (25.4 mm) clearance to provide proper air flow to the unit’s air-to-refrigerant coil.

Installation
WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards.To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow codes could result in death or serious injury.
General Installation Checks
The checklist below is a summary of the steps required to
successfully install a commercial unit.This checklist is
intended to acquaint the installing personnel with what is
required in the installation process. It does not replace the
detailed instructions that are in the applicable sections of
this manual.
1. Remove packaging and inspect the unit. Check the unit
for shipping damage and material shortage; file a
freight claim and notify appropriate sales
representation.
The GEH/V ½-5 ton and EXH/V ½-6 ton units have been
anchored to the skid by (2) shipping bolts. The removal of
these bolts willrequire a 3/8 (9.7 mm) ratchet with a ½ (12.7
mm) socket.
The GEV 6–25 ton units have been anchored to the skid
with (4) angle brackets. Remove these brackets before
lifting unit into place.
The GEH 6–15 ton units are anchored to the cross brace of
the skid with (4) wood screws. Remove these screws prior
to lifting the unit into place.
2. Verify the correct model, options and voltage from the
unit nameplate.
3. Pull out all field attached parts (i.e. filter rack, duct
collar, filter and mounting screws) from the unit
packaging for field mounting.
4. Verify the installation location of the unit will provide
the required clearance for proper operation.
5. Remove refrigeration access panel and inspect the
unit. Be certain the refrigerant tubing has clearance
from adjacent parts.
6. Fabricate and install duct work
7. Install and connect a condensate drain line and trap to
the drain connection.
Main Electrical
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
1. Verify the power supply complies with the unit
nameplate specifications.
2. Inspect all control panel components; tighten any
loose connections.
3. Connect properly sized and protected power supply
wiring to a field-supplied/installed disconnect switch
and to the main compressor contactor/power block
1K1 (compressor contactor on the ½-5 ton) for GEH/V
½-5 ton and EXH/V ½-6 ton units or 1TB1 for GEH/V 625 ton equipment in the unit control panel.
4. Install proper grounding wiresto an earth ground. EXH
and EXV 460 V units require a neutral (a four wire
system).
Note: All field-installed wiring must comply with NEC
and applicable local codes.
Electric Heat Requirements
5. Verify that the power supply complies with the electric
heater specifications on the unit and heater nameplate.
6. Inspect the heater junction box and control panel;
tighten any loose connections.
7. Check electric heat circuits for continuity.
Low Voltage Wiring Requirements
8. Install the zone sensor or thermostat.
9. Connect properly sized control wiring to the proper
termination points between the zone sensor or
thermostat and the unit control panel.
Filter Installation
Each unit ships with 1"(25.4 mm) or 2"(50.8 mm)
throwaway filters. 2" MERV 8 or 2" MERV 13 filters are also
available options.The quantity of filters is determined by
unit size.The GEH 1/2-5 ton and EXH units require field
installation of the 1" or 2" ducted filters rack. All sheet
metal bracket, filter and hardware are in a box located on
the side of the unit within the unit packaging. All ½-25 ton
verticals and GEH 6–15 ton horizontal units ship with the
filter rack and filters factory installed.
Note: Do not operate the unit without filters.
56WSHP-SVX01N-EN
Page 57
Installation
Supply-Air Ductwork
Horizontal ½-5 ton and EXHF units require duct flanges to
be field installed.The duct flange ships in abox on the side
of the unit. Install the flange with (8) 3/8 in. (213 mm)
factory supplied screws.
Install the 1 in. (25.4 mm) supply-air duct flange to the
vertical and horizontal equipment with the
(8) 5/16 in. (7.94 mm) factory-supplied screws.The duct
collar assembly for each unit isshipped with the unit in the
same box where the IOM manual is located.
When attaching the field ductwork to the unit, provide a
watertight flexible connector at the unit to prevent
operating sounds from transmitting through the
ductwork. See Figure 47, p. 57.
Elbows with turning vanes or splitters are recommended
to minimize air noise dueto turbulence and to reducestatic
pressure.
The return-air arrangement may be easily converted from
a free return-air system, to a ducted return-air systemwith
the addition of a return-air side panel. By replacing the
filter racks with the return-air panel, a complete seal from
the duct to the unit is possible.The 1½ duct flange
facilitates ease of field connection to the duct system.This
accessory is typically used when the return-air filter is
placed in a built-in ceiling grille, or placed within a field
provided filter rack assembly.

Install the 1”-2” (25.4 mm/50.8 mm)adjustable filter rackto
the horizontal equipment only with the use of (4) 5/16 in.
(7.94 mm) factory supplied screws.The vertical equipment
factory ships with the filter rack and filter(s) installed.
When attaching the field ductwork to the unit, provide a

Note: The dual-filtration design is typically used in a free-
return application.
The horizontal, GEH and EXH model, allows the installer
flexibility in design applications such as a dual filtration
option.With the dual filtration design, the unit will contain
a lower static which translates into a decrease in filter
maintenance. For installation of a dual filtration accessory
for the GEH and EXH model, verify that an extra set of
return-air filter racks and filter have been ordered from the

For sound-sensitive installations, a vibration pad (field
provided) should be placed beneath the horizontal or
vertical equipment. For the horizontal unit, the pad should
be approximately twice the size of the unit foot print. For
the vertical unit, the pad should be ½ in. (12.7 mm) thick,
and equal to the overall unit foot print.
Hanging the Horizontal Unit
WARNING
Risk of Unit Dropping!
You MUST mount the unit to an area of the ceiling
strong enough to support the weight of that unit. If
unsure, you MUST confirm with a structural engineer.
Failure to do so could result in unit dropping from the
ceiling which could result in death or serious injury, and
equipment damage.
To hang the horizontal configuration (see Figure 54, p. 59):
1. Install the hanging isolators (located in the return-air
section of the unit) into the four hanging brackets.
2. Secure the equipment to a joist, concrete, etc. with the
use of 3/8 in. (9.7 mm) field provided (all-thread) rod.
Each corner should contain field provided nuts and
washers to complete the hanging installation.
Figure 55. Negative pressure system
Install proper trapping to the equipment.The unit drain
connection is ¾ in. NPT for all GEV ½-25 ton and GEH ½5 ton and EXH/V ½-6 ton models. For6-15 ton GEHmodels,
the drain connection is ½ in. PVC schedule 40 pipe.
When designing the condensate trap for the water-source
system, it is important to consider the unit draw-thru
design requiring negative pressure trapping.
In a properly trapped system, when condensate forms
during normal operation, the water level in the trap rises
until there is a constant flow. It is imperative to maintain
water in the trap and not allow the trap to dry out during
heating season. Keeping trap primed at all times will
enable the water to flow properly. See Figure 55, p. 59 for

AUTOMATIC BALANCING
HOSE KIT
Connect the supply and return hoses to the water-inlet
(from supply) and water-outlet (to return) of the unit. For
vibration isolation, it is recommended that flexible steel
braided hoses be installed instead of hard piping the
equipment to the main loop system. Figure 56, p. 60
shows connection of a Hays Measurflo® balancing hose
kit to the water-in and water-out of a vertical unit.
Note: Figure 56, p. 60 example incorporates the Hays
Measurflo® balancing hose kit and a
2-position isolation valve into the system design.
An isolation valve is often used in variable speed
pumping applications.The isolation valve is
designed to stop water flow to the unit during non
operation times.This allows the loop water pumps
to run only when a requirement for pumping is
needed for greater energy efficiency of the overall
system design.
RETURN
TO
LOOP
SUPPLY
FROM
CENTRAL
PUMP
A steel braided hose without a shut-off device is the least
expensive means of connecting the heat pump to the
supply/return water loop.
With the addition of a shut-off device on the supply and
return of the system, the unit may be isolated during
service or maintenance situation.This system may be
installed as a wide open (full water flow to the equipment)
design, or manually balanced by utilizing the pressure/
temperature ports on the top of the ball valve/shut-off
device.

Types of Hose Connections
Whether installing the units in a central pump (main/
auxiliary pump for the entire zone) design, or as a
distributed pump (1-pump per unit) design, a shut-off
device and flexible hose is recommended to transition
from the hard piping of the closed or open loop water
system to the unit.There are multiple hose combinations
whichmay be used to fit the design or specification criteria
for the installation.
Flexible hoses
A circuit setter provides a means of manually balancing
the water flow to the heat pump.This manual in-line
balancing method is accurate up to ±20%. In order to
determine flow rate, the user must record both handle
position, and differential pressure drop.Then, the user
must consult a chart containing both pieces of information
and make the necessary adjustments to the circuit setter.
For self balancing flow control, a Hays Measurflo®
balancing hose kit provides a constant flow rate over the
pressure differential range of2–80psid. As system
pressures change (through the addition of heat pumps, for
example) each individual flow control valve will
automatically adjust to the new system conditions.
Additional accessories, such as a strainer are
recommended for use to eliminate contaminants from
entering the co-axial water-to-refrigerant heat exchanger.
After the piping system is complete, the flexible hose
connectors should be doubled back to complete the water
circuit external to the unit (avoiding trash settle-out in the
condenser). An extra pipe may be necessary to connect
the hose kits.
1. Water circulation system should be filled with clean
water using the water make up connections.
Note: Air vents should be open during filling.
2. With the air vents closed, start the circulating pump
and then crack the air vents to bleed off the trapped air,
assuring circulation through all components of the
system.
Note: Make up water must be available to the system to
replace the volume formerly occupied by the air
that is bled off.
3. With the air vented and the water circulating, the entire
system should be checked for leaks with repairs made
as required.
4. Operate the supplementary heat system (boiler)
making checksper manufacturer’sinstructions. During
this operation, visual checks should be made for leaks
that may have occurred due to increased heat. Repair
as required.
5. Open the system at the lowest point for the initial blow
down (making sure the make up water is equal to the
water being dumped). Continue blow down until the
water leaving the drain runs clear, but not less than 2
hours.
6. Shut down pumps and supplementary heat system.
Reconnect the hoses placing the water-to-refrigerant
heat exchanger in the water circulating system.
Note: Vents should be open when the pumps and
supplementary heat system are shut down.

2-position, water side economizing valve will
become energized (open) and compressor
operation will halt allowing for free cooling in the
space.
5. Turnthe thermostat system switch to the OFF position.
Unit should stop running and the reversing valve
should de-energize.
6. Leave unit off for approximately FIVE minutes to allow
for pressure equalization.
7. Turn the thermostat to the lowest setting.
8. Set the thermostatsystem switch to the HEAT position.
9. Adjust the temperature setting upward until the unit is
energized. Warm air should blow from the register. A
water temperature decrease of approximately 5-9°F
leaving the heat exchanger should be noted.The
blower and compressor operation should be smooth
with no frost observed in the refrigeration circuit.
10. Check the heating refrigerant pressures against values
in Table 54, p. 94.
Note: For units with boilerless electric heat option: In
heating mode, if the entering watertemperature of
the heat pump falls below 45ºF, the electric heater
will be energized, and compressor operation will
halt. Once the entering water temperature rises
above 50ºF, the boilerless controls returns the unit
to normal operation.
11. Set the thermostat to maintain the desired space
temperature.
Note: The valve body is constructed from forged brass with nickel plating, with the ball and stem constructed of stainless steel. For other information
pertaining to the economizing water valve, see the valve’s data plate.

Before energizing the unit, the following system devices
must be checked:
•Is the high voltage power supply correct and in
accordance with the nameplate ratings?
•Is phasing of the unit correct per compressor rotation
(scroll compressor only)?
•Is the field wiring and circuit protection the correct
size?
•Is the low voltage control circuit wiring correct per the
unit wiring diagram?
•Is the piping system clean/complete and correct? (A
recommendation of all system flushing of debris from
the water-to-refrigerant heat exchanger, along with air
purging from the water-to-refrigerant heat exchanger
be done in accordance with the Closed-Loop/Ground
Source Heat Pump Systems Installation Guide).
•Is vibration isolation provided? (i.e. unit isolation pad,
hose kits)
•Is unit serviceable? (See clearance specifications in
“Unit Dimensions and Weights,” p. 14).
•Are the low/high-side pressure temperature caps
secure and in place?
•Are all the unit access panels secure and in place?
•Is the thermostat in the OFF position?
•Is the water flow established and circulating through
all the units?
•Is the duct work correctly sized, run, taped, insulated
and weather proofed with proper unit arrangement?
•Is the condensate line properly sized, run, trapped,
pitched and primed?
•Is the zone sensor correctly wired and in a good
location?
•Does the indoor blower turn freely without rubbing?
•Has all work been done in accordance with applicable
local and national codes?
Has heat transfer fluid been added in the proper mix to
prevent freezing in closed system application?

Initial Unit Start-up
Note: Start-up with the heat pump thermostat is included
below:
1. Set the thermostat to the highest position.
2. Set the thermostat system switch to COOL with the fan
control to AUTO.The compressor should NOT run.
3. Reduce the thermostat setting until the compressor,
reversing valve, solenoid valve, and loop pump are
energized. Adjust water flow utilizing pressure/
temperature plugs and comparing to tables contained
in specification sheet data.
Water leaving the heat exchanger should be warmer
than the entering water temperature (approximately 912ºF); blower operation should be smooth;
compressor and blower amps should be within data
plate ratings; the suction line should be cool with no
frost observed in the refrigerant circuit.
4. Check the cooling refrigerant pressures against values
in Table 54, p. 94.
5. Turnthe thermostat system switch to the OFF position.

Operating Pressures
There are many variables (airflow, air temperatures) in an
air conditioning system that will affect operating
refrigerant pressures and temperatures.The charts below
shows approximate conditions and is based on air flow at
the rated SCFM, entering air at 80.6°F(DB), 66.2°F(WB) in
cooling, 68°F(DB) in heating. (+)Heating data with 35°F
EWT is based on the use of an anti-freeze solution having
a freezing point 20°F lower than the minimum expected
entering temperature.
