Introduction

Read this manual thoroughly before operating or servicing 
this unit.

Warnings, Cautions, and Notices

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.

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

s

Indicates a potentially hazardous 
situation which, if not avoided, could 
result in minor or moderate injury. It 
could also be used to alert against 
unsafe practices.

NOTICE

Indicates a situation that could result in 
equipment or property-damage only 
accidents.

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 
and HCFCs such as saturated or unsaturated HFCs and 
HCFCs.

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 according to local rules. For 
the USA, 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

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 (PPE) 
Required!

Failure to wear proper PPE for the job being undertaken 
could result in death or serious injury. Technicians, in 
order to protect themselves from potential electrical, 
mechanical, and chemical hazards, MUST follow 
precautions in this manual and on the tags, stickers, 
and labels, as well as the instructions below:

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 Safety Data Sheets 
(SDS) and OSHA guidelines for proper PPE.

When working with or around hazardous chemicals, 
ALWAYS refer to the appropriate SDS and OSHA/GHS 
(Global Harmonized System of Classification and 
Labeling 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.
