Routine Maintenance
To clean the UV lamp:
1. Remove the lamp as outlined in Removing and Replacing the UV
Lamp on page 80.
2. Allow the lamp to cool to room temperature to avoid thermal
shock, which could crack the window.
3. Dampen a cotton swab in methanol and dab it into the cleaning
compound. Allow a small amount of the cleaning compound to ad-
here to the cotton tip.
4. Using small circular motions, rub the cleaning compound onto the
lamp window. Do not exert excessive force onto the window, since
the window can be permanently damaged by misuse.
5. Continue cleaning for approximately one minute.
6. Dampen a new cotton swab with methanol and remove any trace
amounts of the cleaning compound from the lamp window.
7. Wipe the window and the lamp with a dry, lint free tissue to remove
any trace amounts of the cleaning compound and methanol. All tra-
ces of cleaning compound must be removed.
8. If you removed an O-ring from the lamp, replace it now. Ensure
your hands are clean and dry.
9. Without touching the lamp window, replace the lamp as outlined
in Removing and Replacing the UV Lamp on page 80.
Cleaning the Lithium Fluoride Window
To clean the 11.7 eV lamp window:
1. Clean the lamp window with dry aluminum oxide powder on a dry
cotton swab. Do not use methanol or water.
2. Wipe the window and the lamp with a dry, lint free tissue to remove
any trace amounts of the cleaning compound and methanol. All tra-
ces of cleaning compound must be removed.
3. The lamp window can also be regenerated by storing the lamp in
a desiccant for at least 5 days.
WARNING:
Do not use methanol to clean the 11.7 eV lamp win-
dow.
