To Install Element

Observe instructions for removing element and proceed in

reverse order. Be sure to replace secondary insulation bushings.

Care of Reflectors

Reflectors should be cleaned periodically. A mild soap and

water solution or fine cleaning powder is best although more

drastic means may be required if reflectors are badly soiled by

chemical 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, may be

used. Reflectors are replaceable and may be purchased from

Chromalox.
