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 protec-
tion 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.
Label all wires prior to disconnection when servicing con-
trols. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.

The blower motor does not have oiling holes. Do not attempt
to oil the blower motor.
