Position the Opener
NOTE:
A 25mm (1") board (1) is
convenient for setting an ideal door-to-rail
distance (unless headroom is not
sufficient).
Raise the opener onto a stepladder. Open
garage door. Place a 25mm (1") board (1)
laid flat on the top section of door near the
centerline as shown. Rest the rail on the
board.
If the raised door hits the trolley, pull down
on the trolley release arm to disconnect the
inner and outer trolley sections. The trolley
can remain disconnected until connecting
door arm to trolley is completed

Hang the Opener
The opener must be securely fastened to a
structural support of the garage.
Three representative installations are shown. Yours
may be different. Hanging brackets (1) should be
angled (Figure A) to provide rigid support. On finished
ceilings, (Figure B) attach a sturdy metal bracket (not
supplied) (4) to a structural support before installing
the opener. For concrete ceiling mount, (Figure C), use
concrete anchors (5) provided.
On each side of opener measure the distance from the
opener to the structural support (or ceiling).
Cut both pieces of the hanging bracket to required
lengths. Flatten one end of each bracket and bend or
twist to fit the fastening angles. Do not bend at the
bracket holes. Drill 4.5mm (3/16") pilot holes in the
structural supports (or ceiling). Attach brackets to
supports with wood screws (2).
Lift opener and fasten to hanging brackets with screw,
lock washer and nut (3). Check to make sure rail is
centered over the door. REMOVE 25mm (1") board.
Operate door manually. If door hits the rail, raise
header bracket. Use rail grease and lubricate bottom
surface of rail (6).
