16 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).

so "NOTICE" reads right side up as shown (3). Secure with an
overhand knot (2). Knot should be at least 25mm (1") from end

Thread other end of rope through hole in release arm of the
outer trolley (4). Adjust rope length so that handle is less than
1.8m (6 feet) above the floor. Secure with an overhand knot.
NOTE: If it is necessary to cut rope, heat seal cut end to
prevent fraying
