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 af fect 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.
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.
Installing/servicing this unit could result in exposure to
electrical, mechanical and chemical hazards.
•Before installing/servicing this unit, t ec hnicians MU ST
put on all Personal Protective Equipment (PPE)
recommended for the w ork being undertak en. ALWAYS
refer t o appropriate MSDS sheets and OSHA guidelines
for proper PPE.
•When working with or around hazardous chemicals,
ALWAYS refer to the appropriate MSDS sheets and
OSHA guidelines for infor mation on allow able personal
exposure levels, proper respiratory protection and
handling recommendations.
•If there is a risk of arc or flash, tec hnicians MUST put on
all Personal Protective Equipment (PPE) in accordance
with NFPA 70E or other country-specific requirements
for arc flash protection, PRIOR to servicing the unit.
Failure to follow instructions cou ld result in death or
serious injury.
Equipment Damage From Ultraviolet (UV)
Lights!
Trane does not recommend field installation of ultraviolet
lights in its air handling equipment for the int e n ded
purpose of improving indoor air quality. High intensity Cband ultraviolet light is known to severely damage
polymer (plastic) materials and poses a personal safety
risk to anyone exposed to the light without proper
personal protectiv e equipment (can cause damag e t o e y es
and skin). Polymer materials commonly found in HVAC
equipment that may be susceptible include insulation on
electrical wiring, fan belts, thermal insulation, various
fasteners and bushings. Degradation of these materials
could result in serious damage to the equipment.
Trane accepts no responsibility for the performance or
operation of our air handling equipment in which
ultraviolet devices were installed outside of the Trane
factory.

Controls
The control system offered to control the unit is a Basic 24V
control for the ½-5 ton and EXH/V070 sizes, a Deluxe 24 V
control option for all unit sizes, a Tracer™ ZN510,
LonT alk™ certified control option for the ½–5 ton and EXH/
V070 unit sizes, or a T racer ZN524, LonT alk certified control
option for all unit sizes.
All power wiring to the equipment is made at the unit
contactor for ½–5 ton, 1 -phase units. F or 3-phase uni ts all
power wiring to the equipment is made to the contactor
and 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 boar d. EXH and EXV 460 V 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 capabil ities depends
upon the type of sensor and/or remote panel selected.
Troubleshooting and connection diagrams for the 24 V
control systems may be located in the bac k of this manual.
All digital control troubleshooting tips and connection
diagrams are located in WSHP-IOP-2 (ZN510) or WSHPPRB002-EN (ZN524).
Basic 24 V Controls
Safety devices for equipment containing the basic 24 V
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 loc kout relay .
This feature will drive dry contacts only, and cannot be
used to drive field installed control inputs. Trane pro vides
a 3½-minute time delay for compressor control.
Deluxe 24 V Controls (option)
Units containing the Deluxe 24V control design will
incorporate a microprocessor-based control board. The
T rane 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 59, p. 102 for diagnostic
information and Figure 58, p. 59 and Figure 59, p. 59 for
thermostat connections.
Tracer ZN510 Controls (½–5 Ton and EXH/V070
units)
The digital ZN51 0 controller is designed to suppor t the ½–
5 ton water-source heat pumps in either a standalone,
peer-to-peer with a Tracer Loop Controller, or as a full
building automation (open protocol) system. The ½–5 ton
units that incorporate direct digital controls will typically
come equipped with the ZN510 control board. The
exception to this would be if the equipment contained hot
gas reheat, waterside economizer, or boilerless control
with electric heat.
WSHP-SVX01L-EN7
Page 8
General Information
Tracer ZN524 Controls (option)
The digital ZN524 controller is designed to support the ½–
25 ton water-source heat pumps in either a standalone,
peer-to-peer with a Tracer Loop Controller, or as a full
building automation (open protocol) system.
For installation, operation and diagno stics of
aforementioned options see the ZN510 and ZN524 WSHPIOP-2 (ZN510) and/or WSHP-PRB002-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 3-way shut-of f 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 applicatio n.
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 65°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 the unit 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 b y
the reheat coil to control not only the space temperature,
but to also reduce the relative humidity of 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 rever sing 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
Product contains fiberglass wool. Disturbing the
insulation in this product during installation,
maintenance or rep air 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.

Supply-Air Ductwork
Horizontal ½-5 ton and EXHF units require duct flanges to
be field installed. The duct flange ships in a box 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 head screws. The
duct collar assembly for each unit is shipped 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 46, p. 53.
Elbows with turning vanes or splitters are recommended
to minimize air noise due to turbulence and to reduce static
pressure.
The return-air arrangement may be easily converted from
a free return-air system, to a ducted return-air system with
the addition of a return-air side panel. By replacing the
filter racks with the return-air pa nel, a complete seal from
the duct to the unit is possible. The 1½ duct flange
facilitates ease of field connection to the mechanical

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.
T o hang the horizontal configuration (see Figure 53, p. 55):
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.
3. Slope horizontal units in two directions. The unit
should contain a dual ¼-12 pitch toward the drain
connection. This will insure proper drainage of the
unit. All plumbing to the unit should conform per
national and local codes and is the responsibility of the
contractor.

Condensate Drain Connection
Figure 54. Negative pressure system
Install proper trapping to the equipment. The unit drain
connection is ¾ in. NPT for all GEV and ½ - 5 ton GEH and
EXH/V 1½-6 ton models. For 6-15 ton GEH models, 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 54, p. 59 for
appropriate dimensions required in a negative pressure
system.
Note: Figure 55, p. 56 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 uni t during non
operation times. This allows the loop water pu mps
to run only when a requirement for pumping is
needed for greater energy efficiency of the overall
system design.
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
which may be used to fit the design or specification criteria
for the installation.
Flexible hoses
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.
Deluxe ball valve hose kit
Supply/Return Pipe Connections
Figure 55. Supply/return pipe connections
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 55, p. 56
shows connection of a Hays Measurflo® balancing hose
kit to the water-in and water-out of a vertical unit.
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 char t containing both pieces of information
and make the necessary adjustments to the circuit setter.
Automatic balance hose kit
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 chec ks per manufacturer’s instructions. During
this operation, visual chec ks should be made fo r leaks
that may have occurred due to increased heat. Repair
as required.
5. Open the system at the lowest point for the in itial 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.
For self balancing flow control, a Hays Measurflo®
balancing hose kit provides a constant flow rate over the
pressure differential range of 2 – 80 psid. As system
pressures change (throu gh 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 exc hanger .
Cleaning and Flushing the Water Loop
After the piping system is complete, the flexible hose
connectors should be doubled bac k to complete the water
circuit external to the unit (avoiding trash settle-out i n 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.

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 contai ned
in specification sheet data. Water leaving the heat
exchanger should be warmer than the entering water
temperature (approximately 9-12ºF); blower operation
should be smooth; compressor and bl ower 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 49, p. 80.
Note: If cooling mode is activated, and the entering water
temperature of the heat pump falls below 55ºF, the
2-position, water side economizing valve will
become energized (open) and compressor
operation will halt allowing for free cooling in the
space.
5. Turn the thermostat system switc h 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 thermostat system switch to the HEA T position.
9. Adjust the temperature setting u pward 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.
