Model 4555 PanelIR TM User Manual Maintenance Instructions
Maintenance
Periodic inspection for dirt and contaminates on the heater, blower mechanism, and
lamps, and removal of such, will ensure that the Model 4555 continues to operate
efficiently and will extend lamp life.
In dirty environments or heating operations the lamps may become contaminated by,
dust, fingerprints or other foreign matter. When this occurs it is recommended that they
be cleaned using the following procedure:
WARNING!
Disconnect all power running to the Model 4555 from the power source and allow the
heater to cool at least five minuets before continuing.
CAUTION!
Wear soft, clean oil-free flannel or plastic gloves when handling quartz lamps. Skin oils
and other contaminant can cause premature lamp failure if they are allowed to reside on
the quartz lamp.
Using a soft, dry, cloth or tissue, wipe the residue from contaminated lamps. A solution
of household strength ammonia and water can be used as a solvent.
The reflector for the Model 4555 heater is made from either polished aluminum or a
high temperature ceramic material. The ceramic reflector is essentially self-cleaning.
Surface heat normally prevents contaminant condensation on the reflector. Increasing
power to the lamp for short time periods will increase the heater temperature resulting in
the removal of most contaminates.
The aluminum reflector can be maintained by cleaning with a soft cloth or tissue. If the
reflector gets scratched or dull, it can be polished with aluminum polish.
