2: Place the Tinnerman clip (18) over the retainer clip crossbar between the two hooks and press it
down firmly until it snaps into place.
3: Insert the bolt (17) through the light baffle socket casting (2). See
Figure 4 .
4: Install the green and yellow ground wire assemblies (19 and 22) on the bolt (17) with the prongs
on the crimped connectors toward the casting. Run both wires through the indent in the lip
around the bolt hole. Secure with nut (10) and tighten securely (6.7 Newton meters).
5: Place the socket assembly (9) into the light baffle socket casting (2). Be sure it is well seated.
6: Install the lamp retainer spring (7). The lamp retainer spring secures the socket. Insert the spring
one end at a time, making sure that the rectangular slot in each side of the spring seats on the
corresponding tab in the casting. See

3: Using the yoke as your handle, raise the housing assembly off of the work surface a few inches
and then firmly tap the housing on the work surface. This should force the reflector out of its
clips.
4: Carefully lift the housing to see if the reflector is released. If it is not, repeat step 3 with slightly
more force.
Installing the Reflector
1: Place the reflector housing casting (1) on a flat work surface with the large opening facing up.
2: Install the reflector support spring (5) in the circular opening at the base of the casting.
3: Insert the reflector (6) at an angle, under any three adjacent legs of the reflector’s clips.
4: Gently press down on the opposite side of the reflector until it snaps into place under the
remaining clips.
Cleaning the Reflector
Remove dust with a blast of oil-free air or wipe with a clean, lint-free cloth. Isopropyl alcohol,
distilled water, or a 50%-50% mixture of each can be used to clean the glass surface.
Note:
The following assumes that all four reflector retainer clips (2) have already been
riveted to the reflector housing casting (1) and the gate bushings (3) have been
installed on the retainer clips. See Figure 8.
Note:
If the reflector does not snap in, turn the casting over. Gently pull on the side of the
reflector that has not snapped in until the rest of the reflector slides into place.
WARNING: Do not use ammonia-based or other harsh commercial cleaners. Clean
reflector only as directed.
Commercially available glass cleaning agents should be avoided as they may
contain ammonia, other harsh chemical detergents or abrasive agents. These
cleaners may damage the glass surface and the Anti-Reflective coatings. Do
not immerse or soak the glass in any cleaning solution.

Assembling the Shutter Barrel
Tools Required:
• #2 Phillips head screwdriver
1: Stand the top and bottom shutter barrel castings (1 and 2) upright with the shutter end of the
castings toward the bottom.
2: Slide the bottom divider plate (4) into its place in the bottom casting (2). The dimples on the
divider plate must point down.
3: With the bottom barrel casting (2) to your left, place two shutter blades (3) on top of the dimple
plate (4) and opposite each other so that together they form a barrier. The handles should extend
past the barrel casting, rivets pointed down. These will be the side shutters (See
Figure 13 ).
4: Place a divider plate (5) on top of the two shutter blades.
5: Place another shutter blade on top of the middle divider plates and perpendicular to the
previously installed shutter blades. This will be the top shutter, so align the handle away from the
bottom casting (2) and then place the other divider plate on top.
6: Place the fourth shutter blade on top of the divider and through the bottom casting in the final
shutter position. Pull the blade and plate assembly slightly forward to allow the handle to slip
through the slot in the bottom casting, and then fully seat the blade assembly into the casting
again.
7: Place the top divider plate (6) on top of the fourth shutter blade.
8: With both shutter barrel castings still standing upright, join the two halves, sliding the handle of
the top shutter blade through the slot in the top shutter barrel casting (1).
9: Starting at the bottom of the castings (closest to the shutters), use four PHMS screws (9) to fasten
the shutter barrel casting halves together, as shown. Hand-tighten only (2.8 Newton meters).
WARNING: During assembly, the shutter springs can pop out of place. Always wear
protective eyewear during this procedure.
Note:
The top shutter barrel casting contains the iris slot.
Note:
The bottom divider plate (4) has four dimples punched into the surface; the top
plate (6) has none. The middle divider plates (5) are noticeably thinner-gauge metal
than the other two.
The notches on the divider plates must fit against the flanges in the casting so that
the plates do not move.
WARNING: Divider plate edges are sharp. Handle with caution.
Note:
Make sure that no shutter assembly components are under the gobo holder guides.
Note:
The ends of the two shutter barrel castings must be even. Adjust them as necessary
before completely tightening the nuts and screws. Failure to do this could interfere
with the barrel rotation.

Shutter Barrel Assembly 13
10: Turn over the shutter barrel assembly so that the narrower end is on your work surface.
11: Install the four shutter springs (7) between the four dimples in the shutter plate and the tabs in
the lip of the casting.
12: Place the iris slot cover (9) over the iris slot. Use two screws (10) to secure the cover.
Note:
Install the springs at the joints in the castings on either of the tabs at the joint. Once
they are installed, the springs at the joints will sit at a slight angle.

Lens Positions
The lens tube casting can accept either original or Enhanced Definition (ED) lenses. The lens
positions are colour-coded within the lens casting to match the coloured dots on the lenses
(see
Figure 15 ). Only lenses bearing at least one dot of the indicated colour should be placed
in that position.
