INSTALLING A LAMP
WARNING! When replacing the lamp, disconnect the
fixture from AC power and allow the lamp to
cool for at least 15 minutes before
proceeding. Wear safety goggles to protect
your eyes.
1 Remove the 2 screws labelled “Lamp replacement”
and pull out the lamp socket.
2 If changing the lamp, remove the old lamp from the
socket.
3 Pre-adjust the lamp socket by turning the 3 lamp
adjustment screws to the middle of their range. There
should be 2 mm (5/64ths of an inch) between each
cap nut and the fixed disk.
4 Holding the new lamp by its ceramic base (do not
touch the glass), align the small pin on the lamp with
the small hole in the socket and insert the lamp
squarely. Make sure that the 4 small projections on the
base contact the face of the socket.
5 Clean the glass bulb with the cloth supplied with the
lamp, particularly if your fingers touched the glass. A
clean, lint-free cloth moistened with alcohol may also
be used.
6 Insert the tip of the lamp into the fixture with as little
twist in the lamp wires as possible. When the base of
the lamp is inside the fixture, turn the lamp assembly
so that the arrow points towards the control panel.
Carefully locate the reflector opening, which is deep
within the lamp chamber, and fully insert the lamp.
7 Align the screw holes and fasten the lamp access
plate with 2 screws.
8 If replacing the lamp, reset the lamp hour and lamp
strike counters as described on page 11.
9 Strike the lamp (after setup is complete) and adjust it
for optimum performance by turning the 3 adjustment
screws one at a time until the brightest part of the
beam is centered.
Cleaning
OPTICAL COMPONENTS
Use care when cleaning optical components. The surface on dichroic filters is achieved by means of special
multi-layer coatings and even small scratches may be visible. Residues from cleaning fluids can bake onto
components and ruin them.
1 Allow the components to cool completely.
2 Wash dirty lenses and filters with isopropyl alcohol. A generous amount of regular glass cleaner may also
be used, but no residues may remain.
3 Rinse with distilled water. Mixing the water with a small amount of wetting agent such as Kodak Photoflo will
help prevent streaking and spotting.
4 Dry with a clean, soft and lint-free cloth or blow dry with compressed air.
