PARTS LIST
Wiring
The appliance, when installed, must be electrically grounded in accor-
dance 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.
CAUTION: Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous opera-
tion. Verify proper operation after servicing.
Blower Motor
The blower motor does not have oiling holes. Do not attempt to oil the
blower motor.

The blower wheel will collect lint and could require periodic cleaning. If
the air output decreases or the noise level increases, it indicates a dirty
blower wheel.
