CLEANING THE
REFLECTORS
Figure 9
5. If cleaning the liner, use a non-abrasive glass cleaner (i.e. household ammonia
and water or isopropyl alcohol) and a clean, dry, lint-free cloth. After
cleaning, do not touch the outside surface of the liner unless wearing cotton
gloves.
6. Reinsert the edges of the liner into the grooves of the quartz-liner bracket.
7. Reinstall the other bracket and secure with the two bracket screws.
8. Repeat this process for the other half of the liner.
Clean reflectors provide the greatest radiant efficiency. If the reflector surface becomes
contaminated, it reflects less energy. The energy that is not reflected is lost, absorbed
by the reflectors, and removed by the cooling water and air.
The following procedure should be used to clean the Model 4069 reflectors:
1. Remove the lamps and quartz liner as described in Lamp
Removal/Replacement/Installation and Split Quartz Liner Cleaning and
Replacement.
2. Clean the reflectors 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 quartz liner, as outlined in Lamp
Removal/Replacement/Installation and Section Split Quartz Liner Cleaning
and Replacement.
If necessary, the reflectors may require re-polishing. This is permissible because the
reflector is solid aluminum and can be re-polished many times without damage from
continued erosion. A fine particle polishing compound, such as a chrome, semi-
chrome, or soft metal polishing compound may be used. These types of compounds
can be found at a local automotive or metal-polishing supply house. Follow the
polishing instructions listed on the polishing product.
