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:
•
(Examples; cut resistant gloves/sleeves, butyl gloves, safety

WARNING
WARNING
CAUTION
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:
Indicates a potentially hazardous situation
which, if not avoided, could result in death
or serious injury.
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
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 Technologies
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 Technologies 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.
Indicates a situation that could result in
equipment or property-damage only
accidents.
Before installing/servicing this unit, technicians MUST put
on all PPE required for the work being undertaken
glasses, hard hat/bump cap, fall protection, electrical PPE
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 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
TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC
FLASH CLOTHING. ENSURE ELECTRICAL METERS AND
EQUIPMENT ARE PROPERLY RATED FOR INTENDED
VOLTAGE.
