Maintenance
Because of its rugged design, superior engineering and
high quality craftsmanship and manufacturing, the King
KB Unit Heater requires little maintenance. With proper
care your electric heater should last a lifetime, however,
seasonal cleaning is recommended to maintain the
efficiency of the heater.
To clean the heating element loosen the 4 Phillips head
screws located behind the louvers in the corners of
the louver housing. Grasp the louver housing on both
sides, lift up and pull out. This provides access to the
heating element. Remove dust or lint with a soft brush
or a vacuum cleaner. Replace the louver housing and
tighten the Phillips head screws.
To clean the fan and motor remove the safety grill from
the rear of the heater. This provides access to the fan
and motor. Wipe the fan and motor with a soft cloth or
brush. The fan motor does not require lubrication.
