LAMP INSTALLATION & REPLACEMENT
TOTALLY EXPOSED OUTDOOR APPLICATIONS
For totally exposed outdoor applications (not
ceiling protected) the connections must be made
as illustrated at right.
CAUTION: Disconnect power before
installing or replacing supplied quartz lamps
or quartz tubes. These elements can and
should be installed prior to mounting heater.
1.
Remove the housing end caps and open
positioning clips.
2.
Position heating elements in “L” slots at
ends of reflector.
3.
Close positioning clips to secure the heating
element in the slot (see figure A).
4.
Carefully wrap heating element pigtail
clockwise around terminal screws (see figure
A). NOTE: Cut
excess pigtail off at
terminal to prevent lead from touching metal
parts. Avoid handling quartz glass as much
as practical. Quartz glass should be wiped
off with a clean cloth.
5.
Tighten terminal screws (see figure B).
CAUTION: Do not draw pigtail so ti
ght
that pressure is put on heating element.
Maintain a partial loop (or looseness) in
the pigtail.
6.
Replace end caps using sheet metal screws
removed in Step 1.
Note: The Mul-T-
Mount heaters are designed
for use with Fostoria quartz lamp infrared
heating elements only.
They are NOT intended
to be used with straight metal rod heating
elements.
POSSIBLE LAMP FAILURE
The heat
ing elements used in this product can be
damaged by contamination (salt deposits from
perspiration or coastal air) on the surface of the quartz
sleeve. At high temperatures, these salts will cause the
quartz to become porous and leak, allowing air to come
in contact with the tungsten element. When this occurs,
the element will burn out quickly and the outer quartz
sleeve can break. The instructions below must be
followed.
• Always wear cotton or latex gloves when installing or
replacing elements.
• Always clean the quartz sleeve with an alcohol
moistened soft cloth before using the heater
• Whenever contamination (milky white appearance on
quartz sleeve) is observed, the element must be
immediately replaced
.
Note: All conduit, conduit fittings and
junction boxes are supplied by the customer.
Red sleeves used for visible light reduction are
not recommended for applications near costal
waters. Purchase lamps with integral light filter
from factory for these applications. See page 13.
