25.2 Cleaning The Lamp Housing Or
Changing The Lamp
If the lamp does not turn on, the instrument will display an error
message to indicate replacement of the lamp may be required.
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 using 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 the fingers
or anything else that may leave a film. Never use acetone or
aqueous solutions.
2. If the lamp does not turn on, remove the 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 sensor cover.
