4. Gently pull the lamp out of the lamp clips, and set aside for disposal.
5. While holding the replacement lamp by the end seals, place the lamp into the
lamp clips located on each end of the heater. Orient the lamp so that the gas fill
tip, formed into the quartz tube of the lamp, points out away from the reflector.
6. Insert the bare wire of each insulated lamp lead into the wire nut that previously
held the old lamp.
7. Form a loop within each lead along its length. This loop will act as a strain relief
within the lead during normal operation of the heater.
8. Reinstall both end covers and secure each to the heater with the end cover screws.
6.2
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 6020 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.
5. Replace the lamps and the heater end covers as outlined in Section 6.1 – Lamp
Removal/Replacement/Installation.
