SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be

hazardous due to system pressure and electrical components. Only

trained and qualified service personnel should install, repair, or

service air-conditioning equipment.

Untrained personnel can perform basic maintenance functions of

cleaning coils and filters and replacing filters. All other operations

should be performed by trained service personnel. When working

on air-conditioning equipment, observe precautions in the

literature, tags and labels attached to the unit, and other safety

precautions that may apply.

Follow all safety codes, including ANSI (American National

Standards Institute) Z223.1. Wear safety glasses and work gloves.

Use quenching cloth for unbrazing operations. Have fire

extinguisher available for all brazing operations.

It is important to recognize safety information. This is the safety-

alert symbol

. When you see this symbol on the unit and in

instructions or manuals, be alert to the potential for personal

injury.

Understand the signal words DANGER, WARNING, CAUTION,

and NOTE. These words are used with the safety-alert symbol.

DANGER identifies the most serious hazards which

will

result in

severe personal injury or death. WARNING signifies hazards

which

could

result in personal injury or death. CAUTION is used

to identify unsafe practices, which

may

result in minor personal

injury or product and property damage. NOTE is used to highlight
