Installation
I. 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 10)
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 11)
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 12)
NOTE: Align square shank of slider with
square in centering hub for proper fitment.
5.
Insert arm attach screw, 1/4-20 x 3/4" FH-Allen
w/Nylon Patch, and tighten. (Figure 11)
6.
Open latch and sweep valves to allow door to
close and observe door and frame alignment.
If door is not resting against emergency stop
release device when closed, reopen door
and use 5/16" hex wrench to rotate slider
centering hub until door comes to rest
against ERS device. (Figure 13)
NOTE:
DO NOT fully open valves. Valves will leak.
7.
When door is completely aligned, tighten
both adjustment set screws.
