Notice

NOTICE:

Warnings and Cautions appear at appropriate sections throughout this manual.

Read these carefully.

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, may result in minor or moderate injury. It

may also be used to alert against unsafe practices.

CAUTION -Indicates a situation that may result in equipment or

property-damage-only accidents.

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

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.
