Installation Manual

Warnings, Precautions, Notices

Safety advisories appear throughout this manual are 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:

Important

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 CFCs 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 Indicates a potentially hazardous situation which, if not avoided, could

result in death or serious injury.

PRECAUTIONsIndicates 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.

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/national 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

Security Recommendations

The following recommendations will help to obtain the best performance of your air-conditioning

unit:

• Do not leave doors and windows open for a long period of time while the unit is in operation

as it will reduce the unit’s air-conditioning capacity.

•Do not place heat sources near the air conditioner as it will reduce the unit’s air-conditioning capacity.

• When the unit is not used for an extended period of time, disconnect incoming power to the

unit.

• If some smell of burning or smoke is detected, immediately disconnect all power supply to the

unit and alert your authorized service agency of the situation. If this condition persists, it could

be due to damages found in the unit which could possibly lead to electric shock or fire.

• Make sure the unit is not close to any type of fuel sprays (at least 1 meter in distance) in order

to avoid fire or explosion hazards.

• Never try to repair the air conditioning unit by yourselves. An erroneous repair could lead to

electrocution or fire. Always call your service agency for all repairs.

• Never splice or join electrical wiring, and never use an extension cord. This practice could lead

to super-heating or fire.

• Electrical power supply should be of appropriate rated amperage and conform to all local

codes.

• In order to prevent electric shock or fire, do not cut or damage power or control cords. If any

of these cords are found to be damaged, request their replacement only to qualified personnel.

• Do not operate the unit without air filters installed. Otherwise, the penetration of debris or dirt

could damage the unit. Filters must be removed and cleaned periodically to ensure their
