Section 5: Maintenance
Do not service the projector while it is connected to AC. There are exposed voltages
that could cause severe physical injuries and possibly death. Disconnect the projector from AC and wait
2 minutes to allow the capacitors on the power supply to discharge before removing the projector’s
covers.
5.2 Cleaning and Maintenance Guide
Power down the projector and disconnect all power sources before cleaning or
servicing.
Table 5.1 Table 4.1. Maintenance Guide
Part Description Frequency How to clean
Projection Lens As required
CLEAN:
A small amount of dust on the lens has very little effect on picture
quality. Clean only if absolutely necessary.
To clean: Moisten a clean (not-reused), lint-free cloth with a high-quality
optical cleaning fluid. Wipe the cloth in a single continuous motion across the
lens surface. Discard the cloth after cleaning. Use compressed air to remove
any particles remaining on the lens.
NEVER use a cleaning solvent that contains ammonia. Avoid lens contact with
Xylene and Ether.
Lamp Module (glass
exit window only) As required Clean (glass only): It is important to never touch the glass surface of the lamp.
Any oil left by fingerprints will seriously degrade a lamp’s performance or
cause “hotspots”, which can lead to an accumulation of intense heat in the
touched area and cause the lamp to shatter. Clean the glass exit surface of the
lamp module only when absolutely necessary.
To clean : Wait until the lamp is completely cool. Moisten a clean, lint-free
cotton cloth with isopropyl alcohol and gently wipe the surface of the glass in a
circular motion until clean.
10000 hours
or sooner, if
required
REPLACE :
Aged lamps that show a drastic reduction in brightness or have
their end of life must be replaced immediately. Refer to
5.4.1 Replacing a
lamp, on page 5-6
.
External Projector
Covers As required
CLEAN:
Clean dust from external covers using a clean, lint-free cotton cloth as
required.
NOTE:
Install the lens cap before cleaning the modules. This will
prevent dust particles from settling on the glass surface of the lens
.
