MAINTENANCE INSTRUCTIONS
For efficient and safe operation and to extend the life of the
heaters, they should be cleaned and inspected for damage at
least annually (preferably at the beginning of the heat season)
or more often in dirty environments. Other than cleaning, your
heaters require no other preventative maintenance. The user
and / or cleaning personnel can perform routine cleaning of the
heater that may be done without disassembly of the heater.
However, any cleaning or servicing that requires disassembly of
the heater must be done by qualified service personnel.
1. Heater cabinet may be cleaned using a damp cloth to
remove dust that may have accumulated on surfaces. Do
not use harsh cleaners and waxes on surfaces since these
could damage the finish or discolor in use.
2. A vacuum cleaner and /or compressed air may be used to
remove dust and lint that may have accumulated inside
heater around element fins. If heater must be disassembled
for cleaning, use care when cleaning element fins to avoiding
damaging fins.
3. After cleaning and servicing, always reassemble replacing
any hardware removed and check units to make sure they
are operating properly.
FINS ARE SHARP AND MAY CAUSE CUTS SO AVOID
CONTACT.
