SERVICE GUIDE FOR ALL PORTABLE DRYERS

FAN MOTOR REMOVAL AND INSTALLATION

In the event of motor failure, remove
the motor as described, and take it
to the nearest service station. An
authorized service station is the only
place that can provide possible mo-
tor warranty. Motor service and re-
pair at other places will be at own-
ers expense.

If the service station determines

motor failure is caused by faulty ma-
terial or workmanship within the war-
ranty period, repair will be covered
under the warranty. Motor failure
caused by external sources will result
in a charge to the owner for repair.
