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
can perform some basic cleaning of the heater. All other servic-
ing is to 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 dissembled for
cleaning, removed the two screws securing front cover and
remove front cover to allow for access to inside. Use care
when cleaning element fins to avoiding damaging fins.
3. After cleaning and servicing, replace front cover and screws
removed making sure cover is properly secured into each
element support bracket at top and bottom – see Figure 7.
4. Energize heater and check for correct operation.
Repainting of Heater Enclosure
The heater is designed with both metal and plastic components.
Repainting of the heater is not recommended as certain paints
may not adhere or work well on both type materials. In addition,
repainting of the heater grille with standard enamel paints (ver-
sus high temperature paints) may result in the grill finish being
damaged by the heated air flowing over these surfaces. If
repainting of the heater must be done, use care to paint only the
exterior cabinet - do not paint the interior, heating element, or
copper limit capillary tube. Follow directions provided by paint
manufacturer for surface preparation and application.
FINS MAY CAUSE CUTS, DO NOT TOUCH.
SERIOUS INJURY OR DEATH COULD RESULT FROM
ELECTRIC SHOCK. MAKE SURE ELECTRICAL POWER
SUPPLY CIRCUIT COMING TO HEATER IS DISCONNECT-
ED AT MAIN DISCONNECT OR SERVICE PANEL BEFORE
CLEANING OR SERVICING THIS HEATER. ALLOW
HEATER TO COOL BEFORE CLEANING TO PREVENT A
POSSIBLE BURN.
