ELECTRICAL SHOCK HAZARD. For your safety,
disconnect electrical power supply to the
unit before servicing or making any electrical
connections to avoid possible electric shock
hazard. Failure to do so can cause serious
injury, or death.
Prior to servicing, label all wires before discon-
necting. Wiring errors can cause improper and
dangerous operation. Verify proper wiring and
operation after servicing.
