Introduction
Read this manual thoroughly before operating or servicing
this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
required. Your personal safety and the proper operation of
this machine depend upon the strict observance of these
precautions.
The three types of advisories are defined as follows:
WARNING
Indicates a potentially hazardous situation which, if
not avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation which, if
not avoided, could result in minor or moderate
injury. It could also be used to alert against unsafe
practices.
NOTICE
Indicates a situation that could result in equipment
or property-damage only accidents.
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.
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 according to local rules. For
the USA, 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
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
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/national
electrical codes.
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
Safety Data Sheets (SDS) and OSHA guidelines
for proper PPE.
• When working with or around hazardous
chemicals, ALWAYS refer to the appropriate
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 METERS AND
EQUIPMENT ARE PROPERLY RATED FOR
INTENDED VOLTAGE.

Table 1. High/low pressure switch
Trip Recover Unit
LP 40 +/-4 56 +/-4 psig
HP 650 +/-10 550 +/-10 psig
Controls
The available control type is a Deluxe 24V control option, a
Symbio™ 400-B/Tracer® UC400-B BACnet® control
option for all unit sizes.
All power wiring to the equipment is made at the unit’s
compressor contactor or optional disconnect switch for the
EXH/V 0.75 to 6 ton units and the DXH/V 2 to 6 ton units.
For units without the disconnect switch, the power wiring
needs to be connected to the screw terminals of the
compressor contactor. All low-voltage wiring is made at the
unit’s low voltage terminal plug.
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 located in the back of this manual.
All digital control troubleshooting tips and connection
diagrams are located in BAS-SVX065*-EN (UC400-B).
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
plug 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).
Symbio™ 400-B/Tracer® UC400-
B (option)
The Symbio 400-B/UC400-B is a BTL Listed BACnet®
controller that can operate stand- alone or within a Building
Automation System (BAS) such as Tracer® SC+. For
installation, operation, and maintenance, see BAS-
SVX065*-EN (UC400-B).
Pump Module (Field Installed
Accessory)
The pump module shall consist of either a single or dual 1/6
HP cast iron pump and a brass three-way shut-off valve.
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.
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 Symbio™ 400-B/UC400-B 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)
This option targets building designs that do not incorporate
a boiler to heat the loop system. During a heavy heating
load, the loop temperature may begin to fall. As the loop
temperature decreases, the heating capacity of the heat
pump will also decrease. In the heating mode, when the
loop temperature falls below 55°F (factory setting), the
electric heater is energized, and the compressor is locked
out. The system’s electric heat source will continue to be
utilized for primary heating until the loop temperature rises

WSHP-SVX014J-EN 9
above 60°F. Once the loop temperature rises above 60°F,
the boilerless controller returns the unit to normal
compressor heating operation and locks out the electric
heater.
For the EXV/H and DXV/H models, the electric heat will be
field installed by the contractor.
Note: The boilerless controller has a field adjustable
entering water temperature setting of 25, 35, 45, 55,
and 60 degrees. The compressor operation will
return to normal operation when the loop
temperature rises 5 degrees above the setpoint.
This electric heat option is designed for primary heat
only, not to run as supplemental heat to the heating
function of the heat pump.

Jobsite Storage
NOTICE
Microbial Growth!
Failure to follow instructions below could result in
odors and damage to the equipment and building
materials.
The floor or foundation must be level and the
condensate drain at the proper height for proper
drainage and condensate flow. Standing water and
wet surfaces inside the equipment can become an
amplification site for microbial growth (mold). If there
is evidence of microbial growth on the interior
insulation, it should be removed and replaced prior to
operating the system.
This unit is intended for indoor use only. To protect the unit
from damage due to the elements, and to prevent possible
IAQ contaminant sources from growing, the unit should be
stored indoors. If indoor storage is not possible, the
following provisions for outdoor storage must be met:
• Place the unit(s) on a dry surface or raise above the
ground to assure adequate air circulation beneath the
unit.
• Cover the unit(s) with a water proof tarp to protect them
from the elements.
