INSTALL VIBRATION ISOLATORS
16
Fit the vibration isolators as indicated to help
eliminate vibration often transmitted through the
mounting surface.
HANG THE OPENER
17
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 sup-
plied) (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 flattened ends of 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 the pole
is centred over the door. REMOVE 50mm board. Operate door manually. If door hits the pole, raise header
bracket.
