PARTS LIST
Wiring
The appliance, when installed, must be electrically grounded in
accordance with local codes or, in the absence of local codes, with
the national electrical Code, AnSI/nFPA 70, if an external electrical
source is utilized. This appliance is equipped with a three-prong
[grounding] plug for your protection against shock hazard and should
be plugged directly into a properly grounded three-prong receptacle.
Do not cut or remove the grounding prong from this plug. For an
ungrounded receptacle, an adapter, which has two prongs and a
wire for grounding, can be purchased, plugged into the ungrounded
receptacle and its wire connected to the receptacle mounting screw.
With this wire completing the ground, the appliance cord plug can
be plugged into the adapter and be electrically grounded.
WARNING
Label all wires prior to disconnection when servicing controls.
Wiring errors can cause improper and dangerous operation.
Verify proper operation after servicing.

oil the blower motor.
