MAINTENANCE
ELECTRIC SHOCK HAZARD. Disconnect all power
before installing or servicing heater. Failure to do

age. Heater must be installed or serviced by a
qualified person in accordance with the National
Electrical Code, NFPA 70.

.
2.

.
4.
Remove element support clips and secondary insulating bushings.
5.
Lift out element.
To Install Element —
Observe instructions for removing element and proceed in
reverse order. Be sure to replace secondary insulating bushings.
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, may be used.
Reflectors are replaceable and may be purchased from Chromalox.
