Part Description Frequency Action
Lens As required Clean the lens only when absolutely
necessary. A small amount of dust on the
lens has very little effect on picture quality.
To clean: Use a soft lint-free cloth without
any chemicals. Use only a high-quality
coated optics cleaning fluid, which can be
purchased from most camera supply stores.
Apply the coated optics fluid directly onto
the lint-free cloth until moistened. Wipe in a
single sweep across the surface of the lens.
To avoid scratching the lens do not
scrub or
rub in a circular motion. Discard the cloth
after every use. Do not use cleaning tools
treated with Ether. Do not use cleaning
solvents that contain ammonia. Use
compressed air to remove any particles
remaining on the lens.
Lamp
As required
CLEAN: Clean if absolutely necessary.
Never touch the glass surface of the lamp.
Fingerprints left on the glass will seriously
degrade lamp performance or cause
“hotspots” which can lead to an
accumulation of intense heat in the touched
area and cause the lamp to shatter.
To clean: Wait until lamp is cool. Moisten a
clean, lint-free cotton cloth with isopropyl
alcohol and gently rub the surface of the
glass in a circular motion until clean.
1000 hrs or sooner
if required
REPLACE: Refer to 4.4 Lamp and Filter
Replacement procedure later in this section.
Filters
Whenever a lamp is
replaced or sooner
if required
REPLACE: Do not reuse old filters. Use the
filter provided in the Christie Lamp and
Filter Kit.
Covers (External) As required
CLEAN: Clean dust from external covers
using a clean, lint free cotton cloth as
required.
NOTE: Before cleaning the modules, it is
recommended that you install the lens cap.
This will keep dust particles from settling on
the glass surface of the lens.
WARNING
Proper face shield and protective gloves are required if
the lamp module is removed from the projector.
