Part Description Frequency How to clean
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.
As required
CLEAN
(front glass only): Clean if
absolutely necessary. Never touch the glass
surface of the lamp. Any oil (left by
fingerprints) 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.
Lamp Module
(300 W P-VIP)
1500 hours or
sooner if required
REPLACE: Refer to 4.4 Lamp Replacement
for instructions.
Covers
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.
