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.

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.

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.

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 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.

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 adequate 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, 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.

Water-to-Refrigerant Coils

The co-axial water-to-refrigerant heat exchanger for the 1 1/2-ton through 6ton equipment is constructed of copper or cupro-nickel (option) for the water section and stainless steel for the refrigeration section.

The heat exchanger is leak tested to assure there is no cross leakage between 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.

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 LonTalk control board will support such options 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 diagnostic 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 required for positive connection to the high and low schrader connections.
