Contains Refrigerant!

System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure before opening the system. See unit nameplate for refrigerant type. Do not use non-approved refrigerants, refrigerant substitutes, or refrigerant additives.

Failure to follow proper procedures or the use of nonapproved refrigerants, refrigerant substitutes, or refrigerant additives could result in death or serious injury or equipment damage.

Proper Field Wiring and Grounding Required!

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 electrical codes. Failure to follow code could result in death or serious injury.

WARNING

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-including industry replacements for CFCs such as HCFCs and HFCs.

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.

Personal Protective Equipment (PPE) Required!

Installing/servicing this unit could result in exposure to electrical, mechanical and chemical hazards.

• Before installing/servicing this unit, technicians MUST put on all Personal ProtectiveEquipment (PPE) recommended for the work being undertaken.

ALWAYSrefer to appropriate MSDS sheets and OSHA

guidelines for proper PPE.

• When working with or around hazardous chemicals,

ALWAYS refer to the appropriate MSDS sheets and

OSHA guidelines for information on allowable personal exposure levels, proper respiratory protection and handling recommendations.

• If there is a risk of arc or flash, technicians MUST put on all Personal Protective Equipment (PPE) in accordance with NFPA 70E or other country-specific requirements for arc flash protection, PRIOR to servicing the unit.

Failure to follow recommendations could result in death or serious injury.

The unit nameplate is located at the front of the unit. It

includes the unit model number, serial number, electrical characteristics,refrigerant charge, and otherpertinent unit data.

Water Connections

½" or ¾" water connections are located on the chassis’s upper section and clearly labeled for water-in/out hose to riser hook-up.

Water-to-Refrigerant Coils

The co-axial water-to-refrigerant heat exchanger for the ¾

ton through 3 ton 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.

ZN510 Controls

Units incorporating the ZN510 control option design will include a digital LonTalk™ certified control board.The 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.The wiring is fed through the left or right conduittube, and intothe cabinet’s control box (contactor). See manual WSHP-IOP-2 for diagnostic information.

Sound Attenuation

Sound attenuation is applied as a standard feature in the product design.The enhanced reduction package includes a heavy gage base plate, and gasket/insulation around the compressor enclosure.

An optional deluxe sound reduction package is also available. It includes a heavy gage base plate, gasket and insulation around the compressor enclosure, and vibration isolation between the chassis and cabinet. An additional dampening treatment is applied around the compressor enclosure to achieve greater acoustical reductions.

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 could result in 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 billof lading is signed at the jobsite, the unit(s) are now the property of the SOLDTO 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 ¾-3 ton equipment.

5. After assuring that charge has been retained, reinstall the schrader caps to assure that refrigerant leakage does not occur.

Jobsite Storage

NOTICE:

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 on the interior insulation, the insulation should be removed and replaced prior to operating the system.

This unit is intended for indoor useonly.To protect the unit

from damage due to the elements, and to prevent possible IAQ contaminant sources from growing, the unitshould 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 provisionsfor 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 growthwhich has been determined to be a cause of odors and serious health related indoor air quality problems.

4. Store refrigeration units (chassis) units in the normal UP orientation to maintain oil in the compressor. Cabinet configurations may be stored as crated.

5. Do not stack units.
