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.

IMPORTANT: Read the entire instruction manual before

starting installation.
