INSTALLATION INSTRUCTIONS
11
TO AVOID DAMAGE TO DOOR AND OPERATOR
ENSURE ALL DOOR LOCKS ARE DISABLED.
USE AN INTERLOCK SWITCH IF A LOCK IS
REQUIRED TO RETAIN FUNCTIONALITY.
WARNING
1. For single slide doors sliding right to open
locate first angle mounting bracket 9” to left of
opening, for doors sliding left to open locate
first angle mounting bracket 9” to right of
opening. (See figure 8)
NOTE:
For bi-parting doors this measurement is 15”.
See figure 9.
2. Set the assembled operator into position and
mark the holes for the angle mounting brack-
ets on the wall, as low as possible without in-
terfering with door travel. (See figure 10) Drill
holes in wall for mounting. Through bolts are
recommended for this purpose. If wall con-
struction does not permit the ue of through
bolts, lag bolts and shields may be used.
3. Secure the assembled operator to the wall.
IMPORTANT: BE SURE OPERATOR
TRACK AND DOOR TRACK ARE PARAL-
LEL. Check that the door clears the power
head when moving. Adjust the track location
on the mounting brackets to the desired posi-
tion and tighten all bolts. It is recommended
that at least one sway brace be used between
the wall and one of the track hangers for in-
creased rigidity, especially on large or heavy
doors. See figure 7A.
4. Mount the disconnect mechanism so that the
top of the bracket is no more than 2” below
the slider carriage ( See figure 8,10, and 11.)
This mechanism may be adjusted both front
and back and up and down to align the dis-
connect pin. It may be necessary to shim be-
tween the mechanism and the door to bring
the pin out into the centerline of the track.
Note: for bi-parting doors, mount both door
disconnect mechanisms. (See figures 9,10,&
11.)
5. It is necessary on a bi-part installation to bring
the doors to a fully closed position for proper
synchronization. With both disconnect pins
engaged in their respective carriages, connect
the drive chain to the bi-part slide assembly
with the hardware provided. See figure 5C
and 7.
6. Install disconnect chain lock as shown in fig-
ure 11, so it will function as described in figure
12.
