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 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, mainte-

nance, 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 accesso-

ries when modifying this product. Refer to the individual

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 applicable electrical codes 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. WARNING

signifies hazards that could result in personal injury or death.

CAUTION is used to identify unsafe practices, which would re-

sult in minor personal injury or product and property damage.

IMPORTANT: Read the entire instruction manual before

starting installation.
