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
and HCFCs such as saturated or unsaturated HFCs and
HCFCs.
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!
Failure to wear proper PPE for the job being undertaken
could result in death or serious injury. Technicians, in
order to protect themselves from potential electrical,
mechanical, and chemical hazards, MUST follow
precautions in this manual and on the tags, stickers,
and labels, as well as the instructions below:
•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
SWITCHING, DISCONNECTING, OR VOLTAGE
TESTING WITHOUT PROPER ELECTRICAL PPE AND
ARC FLASH CLOTHING. ENSURE ELECTRICAL

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 CNT-SVX11*-EN (ZN524). All
digital control troubleshooting tips and connection
diagrams are located in BAS-SVX065*-EN (UC400).
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 3.5-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 64, p. 113 for diagnostic
information and Figure 59, p. 62 and Figure 60, p. 63 for
thermostat connections.
Tracer® UC400 (option)
TheTracer® UC400 is a BTL Listed BACnet® controller that
can operate stand- alone or within aBuilding Automations
system such asTracer® SC. For installation, operation and
Programming, see BAS-SVX065*-EN (UC400).
Tracer® ZN524 Controls (option)
The digital ZN524 controller is designed to support the .5
to 25 ton water-source heat pumps in either a standalone,
or as a full building automation (open protocol) system.
For installation, operation and diagnostics see CNTSVX11A-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 available.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.
8WSHP-SVX01Q-EN
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 or UC400 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 (.5 to 5 ton only), and
a field mounted duct heater option.
If the .5 to5 ton GEH, GEV andEXH/V070 unitincorporates
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 to 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.
the reheat coil to control not only the space temperature,
but to also reduce therelative 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 reversing valve and
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 .5 to 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 .5 -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 to25 ton GEH/Vmodels have indoorblowers 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 to 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
Exposition to glass wool fibers without all necessary
PPE equipment could result in cancer, respiratory, skin
