MAINTENANCE
1. The control and scanner should be powered at all times (except for repair, cleaning or replace-
ment) to reduce any harmful effects of atmospheric humidity.
2. The scanner and sight pipe must be kept clean to prevent overheating and assure optical quali-
ties.
3. When replacing or cleaning the UV tube, note the position of the tube pins. They are mounted
on a rectangular base so that the tube can only be inserted into the socket with the electrodes
broadside to the shutter window.
4. Clean the quartz lens and tube with glass detergent or glass cleaning agents which contain no
abrasives. After cleaning, remove all cleaning films with a soft lint-free cloth. (Some cleaning
films may reduce or filter UV).
5. Use original FIREYE parts to maintain optimum operation.
