Assemble lamp socket Tools Required: • Open-end adjustable wrench or a 7/16” socket • Needle-nose pliers • #2 Phillips screwdriver 18 25 Figure 3 Step 1: Set the crossbar of the retainer clip (25) under the two hooks on the clip bracket as shown in Figure 3. Step 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.
Step 6: 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. Note: If the spring does not seat correctly, coax it into place with a screwdriver or needlenose pliers. 6 13 5 14 1 Figure 5 3 Step 7: Install the bushing cup (5) into the housing socket casting (1) as shown in Figure 5.
Note: Use pliers to straighten the Southco retaining ring (12) if it bends when you install it on the bolt. Step 13: 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.
Reflector Housing Assembly SOURCE FOUR UL 7 12 1 6 8 3 5 10 11 Double-clutch reflector housing for 5°and 10° fixtures.
Remove reflector Tools Required: • minimally padded work surface (cardboard, carpet, or rubber mat recommended) WARNING: This procedure may crack or break the reflector. Always wear gloves, safety glasses, and a dust mask when performing this procedure. Step 1: Place the reflector housing face down on your work surface so that the concave reflector surface points downward. Step 2: Loosen the clutch and rotate the yoke so that it is perpendicular to the housing at roughly a 90° angle.
Install reflector Note: The following assumes all four reflector retainer clips (2) have already been riveted to the reflector housing casting (1) and the gate bushings (3) installed on the retainer clips. Step 1: Place the reflector housing casting (1) on a flat work surface with the large opening facing up. Step 2: Install the reflector support spring (5) in the circular opening at the base of the casting.
Front Barrel Assembly 9 10 4 3 1 8 6 5 Figure 13 7 Shutter Assembly: 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.
Assemble front barrel Tools Required: • Step 1: Note: #2 Phillips head screwdriver Stand the top and bottom front barrel castings (1 and 2) upright with the shutter end of the castings toward the bottom. The top front barrel casting contains the iris slot. Step 2: Note: Slide the bottom divider plate (4), into its place in the bottom casting (2). The dimples on the divider plate must point down. The bottom divider plate (4) has four dimples punched into the surface; the top plate (6) has none.
Step 8: With both front barrel castings still standing upright, join the two halves, sliding the handle of the top shutter blade through the slot in the top front barrel casting (1). Step 9: Starting at the bottom of the castings (closest to the shutters), use four PHMS screws (9) to fasten the front barrel casting halves together, as shown. Torque the screws to 25 inch/pounds. Note: The ends of the two front barrel castings must be even.

Assemble lens tube (19°, 26°, 36°, and 50°) Tools Required: • #2 Phillips head screwdriver Step 1: Place the left and right lens holder castings (1 & 2) face up on your work surface. Align the castings so the colorframe grooves are to your left Step 2: Install lens support pads (4) as required inside both lens holder castings. Four pads are required per lens. Insert pads short-side down, as shown. Step 3: Install the 1/4-20 hex nut (13) in the left lens holder casting as shown.
Cleaning 19°, 26°, 36°, and 50° glass lenses Step 1: WARNING: Step 2: 14 Dampen a clean, lint-free cloth with vinegar or household ammonia. You may use water, but it leave spots. You can remove the spots by polishing the lens gently with a clean, dry cloth. 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.
