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. Wear safety glasses and work gloves. Use

quenching cloth for unbrazing operations. Have fire extinguishers

available for all brazing operations.
Recognize safety information. This is the safety--alert symbol

.

When you see this symbol on the furnace and in

instructions or manuals, be alert to the potential for personal
injury.
Understand the signal words DANGER, WARNING, and
CAUTION. 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 a hazard
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 suggestions which

will

result in enhanced installation,

reliability, or operation.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could cause personal

injury or death.
Before performing service or maintenance operations

on unit, turn off main power switch to unit and install

lockout tag. Ensure electrical service to rooftop unit

agrees with voltage and amperage listed on the unit

rating plate.
