SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can

be hazardous due to system pressure and electrical compo-

nents. Only trained and qualified service personnel should

install, repair, or service air-conditioning equipment.

Untrained personnel can perform basic maintenance func-

tions 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 precau-

tions in the literature, tags and labels attached to the unit, and

other safety precautions that may apply.

Improper installation, adjustment, alteration, service, main-

tenance, or use can cause explosion, fire, electrical shock or

other conditions which may cause personal injury or property

damage. Consult a qualified installer, service agency, or your

distributor or branch for information or assistance. The

qualified installer or agency must use factory-authorized kits or

accessories when modifying this product. Refer to the individ-

ual instructions packaged with the kits or accessories when

installing.

Follow all safety codes. Wear safety glasses and work

gloves. Use quenching cloth for brazing operations. Have fire

extinguisher available. Read these instructions thoroughly and

follow all warnings or cautions attached to the unit. Consult

local building codes and the National Electrical Code (NEC)

for special installation requirements.

Understand the signal words — DANGER, WARNING,

and CAUTION. DANGER identifies the most serious hazards

which will result in severe personal injury or death. WARN-

ING signifies hazards that could result in personal injury or

death. CAUTION is used to identify unsafe practices, which

would result in minor personal injury or product and property

damage.

IMPORTANT: Read the entire instruction manual before

starting installation.
