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 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 pole is centered over the door. REMOVE
50mm or 100mm board. Operate door
manually. If door hits the pole, raise header
bracket.

ATTACH EMERGENCY RELEASE ROPE & HANDLE
Thread one end of rope (1) through hole in top of red handle so
"NOTICE" reads right side up as shown (3). Secure with an overhand
knot (2). Knot should be at least 25mm (1") from end of the rope to
prevent slipping.
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.
DO NOT DISENGAGE THE OPENER TO MANUAL OPERATION WITH CHILDREN, PERSONS OR OTHER
OBJECTS INCLUDING MOTOR VEHICLES WITHIN THE DOORWAY: (The door is under significant tension and if
the door has developed a fault or incorrect tension, it may be unsafe and may fall rapidly.)
