NOTICE:
Warnings and Cautions appear at appropriate sections throughout this manual.
Read these carefully.

NOTICE:
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.
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.
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.

WARNING
Fiberglass Wool!
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:
1. Verify that the nameplate data matches the data on the sales order and bill of
lading (including electrical data).
2. Verify that the power supply complies with the unit nameplate specifications.
3. 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 com-
pleted. 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.
4. Verify that the refrigerant charge has been retained during shipment by use
of gauges. Schrader taps are located external to the cabinet on the 1 1/2-ton
through 6-ton equipment.
5. After assuring that charge has been retained, reinstall the schrader caps to
assure that refrigerant leakage does not occur.
WARNING
Microbial Growth!
Wet interior unit insulation can become an amplification site for
microbial growth (mold), which may cause odors and damage to the
equipment and building materials. If there is evidence of microbial
growth (mold) on the interior insulation, the insulation should be
removed and replaced prior to operating the system.
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:
1. Place the unit(s) on a dry surface or raise above the ground to assure ade-
quate air circulation beneath the unit.
2. Cover the unit(s) with a water proof tarp to protect them from the elements.
3. 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.
4. Store refrigeration units units in the normal UP orientation to maintain oil in
the compressor.
5. Model WPHF units should not be stacked more than three high. Do not stack
WPVJ units.

General
Information
Unit Nameplate
The unit nameplate is located at the
front of the unit. It includes the unit
model number, serial number, electri-
cal 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 test-
ed, dehydrated, charged with refriger-
ant and run tested for proper control
operation.
Water-to-Refrigerant Coils
The co-axial water-to-refrigerant heat
exchanger for the 1 1/2-ton through 6-
ton equipment is constructed of cop-
per or cupro-nickel (option) for the wa-
ter section and stainless steel for the
refrigeration section.
The heat exchanger is leak tested to
assure there is no cross leakage be-
tween the water and refrigerant gas.
Water Connections
Water connections are located at the
unit front for both the WPVJ and
WPHF units. They are clearly labled for
supply/return connection. Sizes are as
follows.
Blower/Motor
The blower and motor is located inside
the unit cabinet. The motor may be
easily removed for service through the
equipment blower access panel.
Controls
The control system offered to control
the unit is a Basic 24 volt control, Basic
24 volt control, or TracerTM ZN510
control. A 50 VA transformer is factory
supplied on the Basic 24V control con-
figurations. A 75 VA transformer is fac-
Dia. Type
3/4" WPHF 021-027 - Water in/out
1" WPHF 030-072 - Water in/out
1" WPVJ - Water in/out
3/4" Drain
1/2" Desuperheater
tory supplied on the ZN510 (digital)
control configurations.
ZN510 Controls
(WPVJ and WPHF option)
Units incorporating the ZN510 control
option design will include a digital
LonTalkTM certified control board. The
control board will support such op-
tions as: random start delay, heating/
cooling status, occupied/unoccupied
mode and fan/filter status.
Power wiring is made at the contactor.
See manual WSHP-IOP-2 for diagnos-
tic information.
Schrader Connections
Connections for the low and high side
of the refrigeration system are located
conveniently at the equipments front
panel. Sheet metal removal is not re-
quired for positive connection to the
high and low schrader connections.
