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, mainte-
nance, or use can cause explosion, fire, electrical shock or other
conditions which may cause personal injury or property dam-
age. Consult a qualified installer, service agency, or your distrib-
utor or branch for information or assistance. The qualified in-
staller or agency must use factory-authorized kits or accessories
when modifying this product. Refer to the individual instruc-
tions packaged with the kits or accessories when installing.
IMPORTANT: Read the entire instruction manual before
starting installation.
