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 such as cleaning coils and filters and replacing filters. All

other operations should be performed by trained service per-

sonnel. 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.

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 a local

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
