Maintenance
Periodic inspection and removal of dirt and contaminants will ensure that equipment can
be operated safely.
In dirty environments or heating operations the lamps may become contaminated with
smoke, dust, fingerprints or other foreign matter. When this occurs it is recommended
that the lamp be cleaned. Doing so will extend the life of the lamp and improve the
heater’s overall performance. Use the following procedure:
WARNING!
CAUTION!
1. With a soft, dry cloth or tissue, wipe the residue from the lamps. Household strength
ammonia can be used to clean the lamps if necessary.
The ceramic reflector is a high temperature material with unlimited life and is essentially
self-cleaning.
CAUTION!
1. Remove both end covers from the Model 4185 by removing the two screws from
each end cover using the Phillips screwdriver.
2. Disconnect lamp leads from terminal blocks.
3. Grasp lamp end and pull the lamp out of heater.
4. Feed one end of the new lamp (wire first) into the lamp slot in end reflector, through
the heater, and into the lamp slot on the heater’s opposite end.
5. Connect lamp leads to terminal blocks.
6. Reinstall both end covers, insert all four end cover screws, and ‘hand tighten’ each
screw using the Phillips screwdriver.
