SAFETY CONSIDERATIONS
Installing and servicing air-conditioning equipment can be
hazardous due to system pressure and electrical compo-
nents. Only trained and qualified service personnel should
install or service air-conditioning equipment.
When working on air-conditioning equipment, observe pre-
cautions in literature and on tags and labels attached to unit.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for brazing operations. Have fire ex-
tinguisher available. Read these instructions thoroughly. Con-
sult local building codes and National Electrical Code (NEC)
(U.S.A. Standard) for special installation requirements.
Before installing or servicing system, always turn off
main power to system. There may be more than one
disconnect switch. Electrical shock can cause personal
injury.
