SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical compo-
nents. Only trained and qualified personnel should install,
repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance func-
tions of cleaning coils and filters. All other operations should
be performed by trained service personnel. When working on
air-conditioning equipment, observe precautions in the lit-
erature, tags and labels attached to the unit, and other safety
precautions that may apply.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for unbrazing operations. Have fire ex-
tinguisher available for all brazing operations.
WARNING:
Improper installation, adjustment, alter-
ation, service, maintenance, or use can cause carbon mon-
oxide poisoning, fire, or an explosion which can result
in personal injury or unit damage. Consult a qualified
installer, service agency, or gas supplier for informa-
tion or assistance. The qualified installer or agency must
use only factory-authorized kits or accessories when modi-
fying this product.
WARNING: Before performing service or mainte-
nance operations on unit, turn off gas supply then unit
main power switch. Electrical shock could cause per-
sonal injury.
