SAFETY CONSIDERATIONS

Installing and servicing air-conditioning equipment can be
hazardous due to system pressure and electrical components.
Only trained and qualified service personnel should install or
service air-conditioning equipment.
Untrained personnel can perform basic maintenance, such as
cleaning and replacing filters. All other operations should be
performed by trained service personnel. When working on air
conditioning equipment, observe safety precautions in litera-
ture, tags, and labels attached to unit.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for brazing operations. Have fire extin-
guisher available. Read these instructions thoroughly. Con-
sult local building codes and the National Electrical Code
(NEC) for special installation requirements.
WARNING: Before installing or servicing system,
always turn off main power to system. There may be
more than one disconnect switch. Turn off accessory
heater power if applicable. Electrical shock can cause
serious personal injury.

the equipment manufacturer.
CAUTION: Do not operate the unit without a filter
or with the grille removed. Damage to the unit or per-
sonal injury may result.
