Maintenance and Troubleshooting

The UV lamp cleaning kit (MX380336) includes aluminum oxide (3.0 micron
powder) and cotton swabs. Additionally, you will require lint free tissues and
approximately 10 mL of methanol. When ordering methanol, specify Spectroscopic
Grade.
WARNING
Never touch the UV lamp with your fingers.
1. Remove the lamp as outlined above.
2. Allow the lamp to cool to room temperature.
This will avoid thermal shock, which could crack the window.
3. Remove the o-ring.
Do not allow the o-ring to come in contact with methanol, as methanol will
degrade the o-ring material and may result in leaks in your system.
4. Dampen a cotton swab in methanol and dab it into the cleaning compound
supplied, allowing a small amount of the cleaning compound to adhere to the
cotton tip.
5. Using small a circular motion, rub the cleaning compound onto the lamp
window for approximately one minute.
Do not exert excessive force onto the window, since the window can be
permanently damaged by misuse.
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 traces of cleaning compound must be removed.
