MAINTENANCE

WARNING: Hazard of Electric Shock. Disconnect all power before servicing heater.

TO REMOVE HEATING ELEMENT

1.Remove terminal cover screws and terminal cover.

2.Disconnect heating element from electrical leads at both ends.

3.Remove screws from porcelain terminal blocks.

4.Remove element support clips and secondary insulating bush- ings (where used).

5.Lift out element.

TO INSTALL ELEMENT

Observe instructions for removing element and proceed in reverse fashion. Be sure to replace secondary insulating bushings and support clips (where used).

WARNING: For your own safety —

Before energizing this heater:

1.Be sure all electrical connections are tightly made. Hold termi- nal with pliers when tightening screw.

2.Be sure that all conductors are properly insulated.

3.Be sure that all element assemblies have been properly replaced, and that secondary insulation bushings and support clips (where used) have not been omitted.

CARE OF REFLECTORS

Reflectors should be cleaned periodically. A mild soap and water solution or fine cleaning powder is best although more dras- tic means may be required if reflectors are badly soiled by chemi- cal or other deposits. The reflector is aluminum. DO NOT use alkali cleaners since alkalies will dull reflector. Mild non-alkaline cleaners, such as used for scouring kitchen sinks, amy be used. Reflectors are replaceable and may be purchased from Chromalox.
