Maintaining the cooling system

The high-intensity laser diode and electronics rely on a variety of components to reduce internal
operating temperatures.
Regular checkup and maintenance of the entire cooling system is critical to prevent overheating and
sudden projector failure and helps make sure reliable operation of all projector components over time.

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.

Power supplies

Power supplies are not serviceable. Never open or attempt to service a power supply. Contact Christie
for a replacement.

Preventative measures
To avoid the risk of scratching the lens, only
clean the lenses if absolutely necessary. A
small amount of dust on the lenses has little
effect on picture quality. The projection lenses
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.
Christie recommends that projectors should be
operated in environments with an AQI (Air
Quality Index) of 50 or lower.if projectors is
operated in environments with an AQI higher
than 50, additional preventative maintenance
may be required. This preventative
maintenance would include cleaning exterior
surfaces and ducts. In this extreme cases the
projectors need to be returned to a Christie
service center to be disassembled and
cleaned. The time between preventative
maintenance cycles will vary based on
environmental conditions.
