MAINTENANCE
Your heater is designed for years of trouble-free operation and
requires no special maintenance other than occasional cleaning.
The motor is permanently lubricated.
Cleaning
At least once each year (or more often in dirty environments),
the heater should be cleaned to remove dust and other foreign
material which has collected during the heating season, as
follows:
1. Turn power off at main switch.
NOTE: With grille removed, the ON/OFF switch located in upper
right corner of heater may be used to turn off power to heater
during cleaning and servicing.
2. Remove front grille by removing the four screws in each
corner.
3. Use vacuum cleaner with brush attachment to remove dust
and dirt that has accumulated in heater (especially around
element and blower blade). Do not use water or any cleaners
to clean heater components.
4. Replace grille.
5. Wipe grille clean with a damp cloth. DO NOT use waxes or
any cleaners that leave a residue since these may discolor
during heater operation.
6. Turn the main line switch on at the switch panel to restore
power to heater. The heater is now ready for another season
of operation.
THE OUTSIDE SURFACES MAY BE CLEANED WITH MILD
DETERGENT AND A DAMP CLOTH BY THE USER.
ALL OTHER SERVICING SHOULD BE PERFORMED BY AN
ELECTRICIAN OR QUALIFIED PERSON
