Installation (cont.)

H. Attach arm to track.

1. With provided 1/8" hex wrench, completely tighten latch and sweep valves by turning clockwise. This will allow for an easier closer-to-door connection. (Figure 9)

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.

• y If door is opened beyond 45°, backcheck may need to be adjusted counter clockwise to easily rotate arm to door position.
• 3. Install slider centering hub through arm into slider. (Figure 10)

NOTE: Countersink recess should face up.

4. Align hub initially as shown and insert two (2) 10-24 x 3/8" Adjustment Set screws. Turn 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 square in centering hub for proper fitment.

NOTE: DO NOT fully open valves. Valves will leak.
