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 ARE SHARP AND 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.
