SAFETY PRECAUTIONS
WARNING:
Ensure all access panels are in place and properly secured before applying power to the unit.
Failure to do so may cause risk of electrical shock.
WARNING:
Before performing service or maintenance on the heat pump system, ensure all power sources
are DISCONNECTED. Electrical shock can cause serious personal injury or death.
WARNING:
Heat pump systems contain refrigerant under high pressure and as such can be hazardous to
work on. Only qualified service personnel should install, repair, or service the heat pump.
CAUTION:
Safety glasses and work gloves should be worn at all times whenever a heat pump is serviced. A
fire extinguisher and proper ventilation should be present whenever brazing is performed.
CAUTION:
Venting refrigerant to atmosphere is illegal. A proper refrigerant recovery system must be
employed whenever repairs require removal of refrigerant from the heat pump.
