MAINTENANCE
7-6
1. If the lamp is operational, clean the lamp window
surface and the lamp housing by wiping it with GC
grade methanol using a cotton swab with moderate
pressure. After cleaning, hold the lamp up to the light at
an angle to detect any remaining film. Repeat the
process until the lamp window is clean. Never use
water solutions to clean the lamp. Dry the lamp and the
lamp housing thoroughly after cleaning.
CAUTION: Never touch the window surface
with fingers or anything that may leave a film.
Never use acetone or aqueous solutions,
especially on 11.7 eV lamps.
2. If the lamp does not turn on, remove the UV lamp from
the lamp housing. Place the lamp O-ring onto the new
lamp. Insert the new lamp, avoiding contact with the
flat window surface.
3. Reinstall the PID sensor module.
4. Tighten the Lamp Housing Cap.
5. If the lamp type has been changed, adjust the lamp type
setting in the programming mode (Section 4.7.8).
When changing between 10.6 eV and 9.8 or 11.7 eV
lamps, it may be desirable to adjust the lamp drive
(LDRV) and lamp fail threshold in diagnostic mode
(see Section 8).
