9. Form a loop within each lead along its length from the top of the cooling manifold
and the ceramic terminal block. This loop will act as a strain relief within the lead
during normal operation of the heater.
10. Reinstall the quartz window by replacing the screws in the window brackets.
11. Reinstall both end covers and secure each to the heater with the two screws per
end cover.
Note: tighten the end cover screws to a torque of 1.7 Ft.-Lbs. [2.3 N-m].
6.2 Quartz Window Cleaning and Replacement: The optional quartz window can
be replaced or removed from the Model 5306B for periodic cleaning. Use the following
procedure to remove/reinstall/clean the quartz window:
1. Loosen the screw that holds the lamp end cover to the end enclosure and remove
the end cover from the end without the electrical wires coming out of the end
enclosure. Remove the lamp lead from the ceramic block. Unclip the lamp from
its holder. With a 9/64 hex wrench remove the 2 screws that mounts the
enclosure to the reflector.
2. Carefully slid the window out of the reflector.
3. If cleaning the window, use Isopropyl Alcohol and a clean, dry, lint-free cloth.
After cleaning, do not touch the inside surface of the window unless wearing
cotton gloves.
4. Reinstall the quartz window into the reflector and reassemble the end enclosure,
hook the lamp back up and clip it back into place..
6.3
Cleaning the Reflector: A clean reflector provides the greatest radiant efficiency.
If the reflector surface becomes contaminated, it reflects less energy. The energy that is
not reflected is absorbed by the reflector, and removed by the cooling water. This energy
is lost energy.
The following procedure should be used to clean the Model 5306B reflector:
1. Remove the lamp as described in Section 6.1 – Lamp
Removal/Replacement/Installation.
2. Clean the reflector with a mixture of warm water and common household
ammonia followed by a thorough wipe-down using a clean, water-dampened
flannel cloth.
3. Depending on the type of contamination present on the reflector, a suitable
solvent may be required to remove the contamination. The solvent must be
selected based on its inability to adversely affect the aluminum reflector.
4. Thoroughly wipe the reflector using the warm water/household ammonia mixture
followed by the dampened flannel cloth.
Replace the lamps, quartz window (if so desired), and the heater end covers as
outlined in Section 6.1 – Lamp Removal/Replacement/Installation.
