Assemble Fixture
Step 1:Place the left barrel casting (1) open side up on your work surface with the
colorframe end to your right.
Step 2:If necessary, place spring (17) over post in right and left castings (1 and 2).
Secure with clip (18).
Step 3:Set shutter assembly (see Shutter Assembly, page 9) into the shutter slot in left
casting (1) with the rounded side of the shutter handles facing right (gel opening
end of the fixture).
Step 4:Install the short end (without the flattened notch) of the gel retainer clip (5) in the
left casting (1).
Step 5:Position clip (5) in the forward, locked position, then install the retainer spring (8)
on the clip.
Step 6:Snap spring (7) onto reflector (6) and place assembly into left casting (1) so that
the front edge of the reflector is supported by spring (17). The spring (7) on the
back rests in the left casting rear supports.
Step 7:Gently set the right barrel casting (2) onto the left casting so that the gel clip
retainer, shutter assembly and reflector assembly fit into their respective
positions.
Step 8:Starting with the corner nearest the gel clip retainer, attach the right casting to
the left casting with screws (22). Do the right screws first, then the middle screws,
then the left screws.
Step 9:Install the iris slot cover (20) onto the barrel assembly with screws (21).
Step 10: With the colored dot on the lens facing out the barrel, slide the lens holder
assembly (or assemblies, if Zoom) into the lens holder track inside the barrel.
The assembly should slide smoothly in the track.
Step 11: Insert light baffle strip (19) through front of barrel assembly and through hole in
lens holder assembly. Slide strip (19) through supports in front of fixture and
install screw (15), spring (24), washer (23), and knob (4).
Step 12: Attach the lamp burner (3, see Lamp Socket Assembly, page 3) to the barrel
assembly with the knurled head screw.
Step 13: Attach yoke (10) to barrel assembly with bolts (12) and washers (14). Attach yoke
knob (11) with bolt (13) and washer (14) to side of fixture with clutch plate.
Step 14: Tighten bolts (12) to secure yoke to fixture. Tighten yoke knob (11) to secure
yoke in desired position.
Clean reflector
Remove dust with a blast of oil-free air or wipe with a clean, lint-free cloth using alcohol or
distilled water (alcohol is recommended).
WARNING:

Do not use glass and window cleaners on the reflector. Chemicals in these
cleaners will stain the reflector.

Step 17: Insert the bolt (17) through the light baffle socket casting (2). See Figure 4.
Step 18: Install the green 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 torque to 60
inch pounds.

Step 20: Install the lamp retainer spring (7). The lamp retainer spring secures the socket.
Insert the spring one end at a time, making sure the rectangular slot in each side
of the spring seats on the corresponding tab in the casting.

Step 21: Install the bushing cup (5) into the housing socket casting (1) as shown in Figure
5. The cup should slide smoothly up and down, but not side to side.
Step 22: Insert the threaded end of the index hub (6) through the holes in the bushing cup
and the back of the housing socket casting (1).
Step 23: Slide the X-Y knob (3) over the exposed index hub bolt (6), then insert the wave

Note:
Use pliers to straighten the Southco retaining ring (12) if it bends when you install
it on the bolt.
Step 27: Lay the leads in the bottom half of the cable clamp (located in the housing socket
casting [1]), making sure that the fiberglass sleeving extends slightly past the
screw holes in the housing socket casting. Install new sleeving if necessary.
Then, route the wires as shown in Figure 7.
CAUTION:
Step 28: Install the top half of the cable clamp (15) and secure it with the two screws (16).
Note:
Step 29: Using the four screws (24), attach the handle (23) to the lamp socket assembly.

You must follow the wire routing diagram to ensure that the socket leads do not
interfere with the lamp focus mechanism.
Tighten the screws alternately to ensure a solid connection.
To ensure that the clamp holds the cable tightly, flatten the cable, then fold over
the sleeving before you install the top half of the clamp. Make sure the top edge
of the cable clamp is even with the edge of the socket to prevent interference with
lamp focus movement. Make sure sleeving is not pinched.

Step 1:Place the lens on the lens holder between the tabs. The paint dot should be on
the side opposite the tabs.
Step 1:Position the lens by centering the paint dot above the bottom tab notch, as shown
in Figure 8. This will keep the paint dot visible after the fixture is fully assembled.
Step 2:Center one Tinnerman clip (18) on each tab, and press clip until it is fully seated.
If clips are in uneven positions, lens will be tilted or loose.
Step 3:Firmly press the clips down and then push the spine of each clip towards the
center of the lens. This will ensure that the clips contact the lens surface.
Step 4:Check lens and make sure the clips hold it securely.
Step 5:Snap the bushings (17) onto the lens holder assembly as shown.
Assemble Zoom Front Lens:
Step 1:Position the lens (9) between the lens holder (4) and the lens cover (11) so that
the convex side of the lens faces the lens holder, as shown inFigure 8.
Step 2:Align the holes in the lens cover with the holes in the lens holder as shown.
Step 3:Secure the lens cover and the lens to the lens holder using screws (14) and
locking nuts (15). Tighten securely to ensure the lens cannot move.
Step 4:Snap the bushings (17) onto the lens holder (4) as shown.
Assemble Zoom Rear Lens:
Step 1:Slide spacers (16) over the PEM studs of the secondary aperture plate (13), as
shown in Figure 8.
Step 2:Insert the PEM studs on the secondary aperture plate (13) through the holes in
the lens holder (5).
Step 3:Position the lens (10) between the lens holder (5) and lens cover (12) as shown.
The blue orientation marks on the lens should face the lens holder.
Step 4:Insert the PEM studs of the secondary aperture plate (13) through the lens cover
(12).
Step 5:Secure the lens cover, lens, and aperture plate using nuts (15).
Step 6:Snap the bushings (17) onto the lens holder (5) as shown.
Cleaning 19°, 26°, 36°, and 50° glass lenses
Step 1:Dampen a clean, lint-free cloth with vinegar or household ammonia. You may
use water, but it leaves spots. You can remove the spots by polishing the lens
gently with a clean, dry cloth.
WARNING:
Step 2:Starting from the center, gently wipe the lens.
Never use glass and window cleaner or any abrasive material to clean the
lens. Glass and window cleaners will stain the lens surface. Abrasive
materials (such as steel wool) will damage the surface of the lens.
