Note: Do not attempt to repair any
damaged parts until the parts
are inspected by the carrier’s
representative.
Overview
Your unit is designed to comfort
condition all year long with safe,
efficient, trouble-free operation. It is
important that you understand how
to operate and maintain your unit to
keep it operating safely and
efficiently. This manual will acquaint
you with these important procedures.
Familiarize yourself with this manual
and store it in a convenient location
for future reference.
Important!
Equipment is shipped FOB (Free on
Board) at the manufacturer.
Therefore, freight claims for
damages against the carrier must be
initiated by the receiver.
Unit contains HCFC (R-22) Refrigerant
Instructions!
Section 608, Paragraph C of the 1990
Clean Air Act states:
Effective July 1, 1992, it shall be
unlawful for any person, in course of
maintaining, servicing, repairing, or
disposing of an air conditioning
system, to knowingly vent or release
any CFC or HCFC refrigerant. Minimal
releases (air purges or refrigerant
hoses) associated with good faith
attempts to recapture or recycle are
exempt from the ban on venting.
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.
Jobsite Inspection
Always perform the following checks
before accepting a unit:
Verify that the nameplate data
matches the data on the sales order
and bill of lading (including electrical
data).
Verify that the power supply
complies with the unit nameplate
specifications.
Visually inspect the exterior of the
unit, for signs of shipping damage.
Do not sign the bill of lading
accepting the unit(s) until inspection
has been completed. Check for
damage promptly after the unit(s)
are unloaded. Once the bill of lading
is signed at the jobsite, the unit(s)
are now the property of the SOLD TO
party and future freight claims MAY
NOT be accepted by the freight
company.
Verify that the refrigerant charge has
been retained during shipment by
use of gauges. Schrader taps are
located internal to the cabinet.
After assuring that charge has been
retained, reinstall the schrader caps
to assure that refrigerant leakage
does not occur.
WARNI NG
Microbial Growth!
Wet interior unit insulation can
become an amplification site for
microbial growth (mold), which may
cause odors and serious health
related indoor air quality problems.
If there is evidence of microbial
growth (mold) on the interior
insulation, remove or replace the
insulation prior to operating the
system. Failure to remove microbial
growth could result in serious health
problems.
Jobsite Storage
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.
Make provisions for continuous
venting of the covered units to
prevent moisture from standing on
the unit(s) surfaces. Wet interior unit
insulation can become an
amplification site for microbial
growth (mold) which has been
determined to be a cause of odors
and serious health related indoor air
quality problems.
Store units in the normal UP
orientation to maintain oil in the
compressor.
Horizontal units may be stacked no
more than three units high. Do not
stack the vertical unit configurations.
Unit Nameplate
The unit nameplate is located on the
outside of the control box access
panel at the front of the unit. It
includes the unit model number,
serial number, electrical
characteristics, refrigerant charge,
and other pertinent unit data.
Compressor Nameplate
The nameplate for the compressors
are located on the compressor shell.
Unit Description
Before shipment, each unit is leak
tested, dehydrated, charged with
refrigerant and run tested for proper
control operation.
Air-to-Refrigerant Coil
The air-to-refrigerant coil is
aluminum fin, mechanically bonded
to the copper tubing.
Water-to-Refrigerant Coil
The water-to-refrigerant coil is a
copper or cupro-nickel (option) and
steel tube (tube-within-a-tube)
design, leak tested to assure there is
no cross leakage between the water
tube (copper/cupro-nickel) and
refrigerant gas (steel tube).
Controls
The control system offered to control
the unit is a Basic 24 Volt control for
the 1/2 through 5 ton sizes, a Deluxe
24 Volt control option for all unit
sizes, a Tracer™ ZN510, LonTalk™
certified control option for the 1/2
through 5 ton unit sizes, or a Tracer
ZN524, LonTalk certified control
option for all unit sizes.
All power wiring to the equipment is
made at the unit contactor for the 1/2
through 5 ton, and at the high
voltage terminal block for the 6
through 25 ton. All low voltage
wiring is made at the unit’s low
voltage terminal board.
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.
WSHP-SVX01E-EN5
General Information
Troubleshooting and connection
diagrams for the 24 Volt control
systems may be located in the back
of this manual. All digital control
troubleshooting tips and connection
diagrams are located in WSHP-IOP-2
(ZN510) or WSHP-PRB002-EN
(ZN524).
Basic 24V Controls
Safety devices for equipment
containing the basic 24V control
option include a low pressure switch
or suction line temperature sensor to
prevent compressor operation during
low temperature activity. The switch
or sensor is set to activate at
refrigerant pressures of 20 psig (1/2
to 5 ton units) or 7 psig (6 to 25 ton
units) to fit most applications.
A high pressure switch prevents
compressor operation during high or
excessive discharge pressures
exceeding 395 psig.
The lockout relay communicates the
low or high pressure situation to the
compressor to prevent operation. For
units that contain a condensate
overflow switch option, a condensate
overflow situation will also be
communicated to the compressor
through the lockout relay if an
overflow condition exists. The relay
may be reset at the thermostat, or by
cycling power to the unit.
General alarm is accomplished
through the lockout relay and is used
in driving light emitting diodes
(LEDs). This feature will drive dry
contacts only, and cannot be used to
drive field installed control inputs.
Trane recommends 3 minute or
greater minimum off time 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). SeeTa bl e 3 4 for diagnostic
information and Figure 62 and
Figure 63 for thermostat connections.
Trane recommends 3 minute or
greater minimum off time for
compressor control.
Tracer ZN510 or ZN524
Controls (option)
The digital ZN510 and ZN524
controller is designed to support the
1/2 through 25 ton water-source heat
pumps in either a standalone, peerto-peer with a Tracer Loop Controller,
or as a full building automation
(open protocol) system. The 1/2
through 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. The ZN524 digital
control board is designed to interface
and run these mechanical options. All
units over 5 tons would ship with the
Tracer ZN524 control board.
For installation, operation and
diagnostics of the ZN510 and ZN524
WSHP-IOP-2 (ZN510) and/or WSHPPRB002-EN (ZN524).
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.
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 1/2 through 5 ton GEH and GEV
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.
If the unit contains a cooling only
heat pump design, the electric heat
contactor is wired directly to the
thermostat for primary heating, and
the compressor contactor for
cooling.
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 6 through 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
6WSHP-SVX01E-EN
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
by 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 reversing
valve, or reheat coil for
dehumidification.
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 1/2
through 5 ton equipment only).
Note: A high static blower motor is
required to support the hot
gas reheat option for the 1/2
through 5 ton equipment.
Note: Units containing the hot gas
reheat option should not be
used as a make-up air unit.
Note: Water regulating valves
should not be used with the
hot gas reheat option. Trane
places a thermal expansion
valve on all WSHPs as well as
GSHPs to regulate refrigerant
flow vs. water flow to the
unit.
