Maintenance
CAUTION: Do not attempt to operate this unit while it is plugged into the AC outlet. Failure to unplug the unit
from the AC outlet before disassembly will result in an electrical shock hazard.
WARNING: Do not attempt to operate this unit in the disassembled condition as that may expose the eyes and
skin to shortwave UV light that is harmful to the unprotected eyes and skin!
This unit is virtually maintenance free. If the lamp fails to start, check to see that:
1. The unit is plugged in.
2. The drawer is pushed all the way in (listen for the click of the limited switch).
3. The timer is on.
4. Check the fuse to see if they are operational.
If a problem still exists, return the unit to the factory for inspection and repair. If the unit has been heavily used
for a long time, it may be desirable to replace the lamp to reduce erase times to their original values.
