Installation
K. 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 15)
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.
NOTE:
• With latch and sweep valves tightened,
arm will maintain position.
• 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 16)
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 17)
NOTE: Align square shank of slider with
square in centering hub for proper fitment.
5.
Insert 1/4-20 x 3/4" flat head socket hex screw
and tighten.
6.
Open latch and sweep valves to allow door to
close and observe door and frame alignment.
If door is not centered in frame when closed,
reopen door and use 5/16" hex wrench to
rotate slider centering hub until door is
centered. (Figure 18)
NOTE:
DO NOT fully open valves. Valves will leak.
Door should be centered in frame when in
closed position. Adjust slider centering hub
with hex wrench until door and frame are
aligned properly then tighten adjustment
set screws.
