Ventilation

Use the following guidelines when maintaining ventilation.
• Do not place the projector near a heat source or in an enclosure, unless proper ventilation is
provided.
• Do not insert objects into the ventilation openings of the projector.
• Do not spill liquids of any kind into the projector. Should an accidental spill occur, immediately
unplug the projector and have it serviced by a qualified service technician.

Cleaning the projector optics

Learn about cleaning the optical components in the projectors.
Unnecessary cleaning of optics, increases the risk of degrading delicate coatings and surfaces. Only
clean optics when dust, dirt, oil, fingerprints or other marks are obvious and are causing performance
problems. Maintenance of optical components requires a qualified service technician. Inspect exposed
optical surfaces periodically in a clean, dust-free environment using a flashlight.
Never touch an optical surface with your bare hands. Always wear latex lab gloves.
Use the following products when cleaning the optical surfaces:
• Soft camel-hair brush
• Dust-free blower—filtered dry nitrogen blown through an anti-static nozzle.
• Dust-free lens tissue, such as Melles Griot Kodak tissues (18LAB020), Opto-wipes (18LAB022),
Kim Wipes or equivalent
• Cotton swabs with wooden stems only
• Lens cleaning cloth/microfibre, such as Melles Griot (18LAB024) or equivalent

Cleaning the lens

To avoid the risk of scratching the lens, clean the lens only if absolutely required.

Removing dust from the projection lens

Remove dust from the projection lens to ensure optimum image display.
1. Brush most of the dust off with a camel-hair brush or use a dust-free blower.

Preventative measures
absolutely necessary. A small
amount of dust on the lenses has
little effect on picture quality. The
projection lens should be free of
dust and fingerprints. If the lenses
must be cleaned, use a dry, soft
cotton cloth and gently rub in a
circular motion.
