Warnings, Cautions, and Notices

Read this manual thoroughly before operating or servicing this unit.

Safety advisories appear throughout this manual as required.Your

personal safety and the proper operation of this machine depend upon

the strict observance of these precautions.

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.

Important 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.

The three types of advisories are defined as follows:

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, could result in minor or

moderate injury. It could also be used to alert

NOTICE

Indicates a situation that could result in

equipment or property-damage only accidents.

WARNING

Proper Field Wiring and Grounding Required!

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

WARNING

Personal Protective Equipment 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 PPE

required for the work being undertaken (Examples; cut resistant gloves/

sleeves, butyl gloves, safety glasses, hard hat/ bump cap, fall protection,

electrical PPE and arc flash clothing). ALWAYS refer to appropriate Material

Safety Data Sheets (MSDS)/ Safety Data Sheets (SDS) and OSHA guidelines

for proper PPE.

• When working with or around hazardous chemicals, ALWAYS refer to the

appropriate MSDS/SDS and OSHA/GHS (Global Harmonized System of

Classification and Labelling of Chemicals) guidelines for information on

allowable personal exposure levels, proper respiratory protection and handling

instructions.

• If there is a risk of energized electrical contact, arc, or flash, technicians

MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-

specific requirements for arc flash protection, PRIOR to servicing the unit.

NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING

WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE

ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED FOR

INTENDED VOLTAGE.

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

General Information

1. Clean the lines of all foreign material, (welding slag, pipe scale, dirt,

thread chips, etc.). Upstream installation of a strainer may be

necessary in dirty systems.

2. Air should be eliminated from the system prior to startup to assure

quiet operation and freedom from water hammer.

3. Flow control valves may be installed horizontally, vertically or any

angle in between. Additional straight sections of pipe upstream or

downstream of the automatic flow control valves are unnecessary for

proper operation.

4. Standard reducing bushings or flanges may be directly connected to

the hose ends if required.

5. The ATC actuator may be mounted above or along side of piping but

must never be mounted where condensation can accumulate or

come in contact with electrical or mechanical components.

6. Automatic control valves are marked with direction of flow.

Automatic valves will be labeled with the GPM and the water valve Cv.

Important: The arrow must point in the direction of flow for proper

operation.

7. Automatic flow control valves must be located in the RETURN Line.

Valves without removable parts are to be set to the open position to prevent thermal damage. j. Heat may be applied, either to the tubing or to the end of the fitting so as to achieve solder flow. k. When the parts have achieved the necessary temperature; solder is to be added to the joint and the joint allowed to cool. l.
