With provided 1/8" hex wrench, completely

CAUTION: Arm will be under strong spring force
to return if valves are not tightened completely
closed.
2.
Open door to about 45° then rotate arm over
to door.

• With latch and sweep valves tightened,
arm will maintain position.

may need to be adjusted counter
clockwise to easily rotate arm to door
position.

Install slider centering hub through arm into
slider. (Figure 10)
NOTE: Countersink recess should face up.

both set screws just enough to retain slider
centering hub. Do not tighten firmly at this
time. (Figure 11)
NOTE: Align square shank of slider with

Insert arm attach screw, 1/4-20 x 3/4" FH-Allen
