6 Routine Maintenance
It is very important to perform routine maintenance on both the enclosure and the projector
inside it. Failure to do so may reduce lifetime for both the enclosure and the projector.
Note
Maintenance schedules depend on location and environment. The intervals given here are
general minimum guidelines. It is up to the user to judge whether maintenance should be carried
out more frequently. We recommend doing these tasks no less often than mentioned here.
Safety
As the enclosure is a powered unit with moving parts, it is necessary to keep safety in mind while
performing routine maintenance. Although maintenance can be performed while the enclosure is
powered, it is safer to carry it out with the power disconnected with proper lockout and tag out
procedures followed.
Be aware that once the enclosure has had power applied to it, the fan will start to turn. Make
sure that your hands are clear of the fan before applying power to the enclosure.
Only authorized personnel should perform maintenance on the enclosure or projector
Do not service the unit in the rain or other adverse weather conditions (snow, sleet, high winds,
etc.).
Inspection Checklist: - Every Three (3) Months
Glass should be clean and free of cracks
Enclosure should be free of debris both inside and out
Bolts and tie-down straps should be tight
Door seals should be in good condition. Check seals inside and out for gaps.

Intake filter should be clean
Air Filter - Every Three (3) Months
The air filter from the intake vent on front of enclosure
(back on 6550/6560) should be removed and cleaned on a
regular basis. To remove filter, pull pull it directly out of
the intake vent. The filter can be cleaned by running water
from a hose and do not require any special solution.
To reinstall, push filter back into Velcro on the bottom of
the intake vent. Filter should be flush with bottom of vent.
