Tools required: Open-end adjustable wrench or a 7/16" socket,
needle-nose pliers, screwdriver.
1. Install the screw (20) into the light socket baffle casting as
shown in figure 1. (Also see figure 7 on page 7.)
Note: Do not install the screw if the fixture will be used with 77V
lamps and ETC’s Dimmer Doubler. This screw prevents 77V
lamps from being installed.
2. Insert the bolt (19) through the light baffle socket casting (2).
3. Install the green ground wire assemblies (21 and 24) on the bolt
(19) 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 (12) and torque to 60 inch pounds.
4. Place the ceramic TP22 socket (11) into the light baffle socket
casting (2) as shown in figure 2. Be sure it is well seated. Firmly
push the connectors on the white TP22 leads (10) into the
grooves in the socket.
5. Place the TP22 mica (9) over the leads, then install the lamp
retainer spring (7). The lamp retainer spring secures the mica.
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.
Important: If the spring does not seat correctly, coax it into place
with a screwdriver or needle-nose pliers.
6. Install the bushing cup (5) into the housing socket casting (1) as
shown in figure 3. The cup should slide smoothly up and down,
but not side to side.
7. 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).
8. Slide the X-Y knob (3) over the exposed index hub bolt (6), then
insert the wave washer (16) on the bolt and secure with the 9/16
hex nut (15). Hand tighten the X-Y knob (3).
Note: Install the wave washer with the upward curve toward the
hex nut.

9. Insert the knurled head screw (13) through the housing socket
casting (1) as shown in figure 4.
10. Install the shorter green ground wire (24) with the prongs on the
crimped connector toward the casting onto the screw.
11. Install the ground spring (23) onto the screw and secure it with
the Southco flat retaining ring (14). Install the Southco ring with
its prongs away from the casting.
Note: Use pliers to straighten the Southco retaining ring (14) if it
bends when you install it on the bolt.
12. Lay the leads in the bottom half of the cable clamp, 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 5.
Important: You must follow the wire routing diagram to ensure
that the socket leads do not interfere with the lamp focus
mechanism.
13. Install the top half of the cable clamp (17) and secure it with the
two screws (18) as shown in figure 6. Tighten the screws
alternately to ensure a solid connection.
Note: 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.

14. Place the spring (8) on the protrusion on the inside of the index hub
(6).
15. Insert bolt (19) through the light socket baffle (2), thread nut (12),
through spring (8) and through the index hub (6) of the housing
socket (1), joining the two castings. Make sure wires are not
pinched between the two pieces.
16. Before proceeding, check again to make sure the wires are still
positioned as indicated in figure 5. Adjust if necessary.
17. Press the two castings together firmly so the bottom of the light
baffle (2) sits on top of the cable clamp (17), then install the X-Y
lampset (3) and Z lamp knob (4). Hand tighten the knob all the way
to the right.
Important: You must install Z knob as described above to ensure
proper lamp focus travel.
18. Set the crossbar of the retainer clip (25) under the two hooks on the
clip bracket as shown in figure 7.
19. Place the Tinnerman clip (26) over the retainer clip crossbar be-
tween the two hooks and press it down firmly until it snaps into
place.

Fixed Field Angle Lens
1. Position the lens by centering the point dot between the three tabs,
as shown below in figure 8.
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.
3. Firmly press each clip down and roll it away from the center of the
lens to ensure contact on lens surface.
4. Check lens and make sure the clips hold it securely.
5. Snap on the bushings (17).
