Owner Installation Instructions
WARNING:
The opener must be securely fastened to
structural supports, otherwise opener failure may ensue
causing serious personal injury and/or property damage.
Step 8 - Determine the Door’s Centre
Find the centre of the door and mark this location
both above the door and on top of the door.
Draw two lines 21.5mm either side of this
(Fig. 20)
.
Step 9 - Prepositioning the Opener
Raise the door to open position.
Rest the opener on the top edge of the door with
end of the rail against the wall
(Fig. 21)
.
Support the powerhead level with the lowest point
of the open door
(Fig. 21)
.
NOTE:
Do not slide rail along the face of the door.
Step 10 - Mounting the C-Rail
Close the door slowly. The rail will be elevated by
the top edge of the door as it moves.
Stop the door when it is at its highest point of travel.
Allow 25mm additional height for clearance between
the door and the track
(Fig. 22)
.
Support the Rail in this position and close the door
The height determined in Step 10 (b) will be the
height at which to mount the wall bracket.
Centre the bracket along the line determined in Step
8
Using the bracket as a template, mark a minimum of
two holes and drill with appropriate size bit. For a
more secure fi tting, the wall bracket can be anchored
using more than two holes.
Secure the bracket to the wall using:
IF CONCRETE OR BRICK - 8mm (5/6”) loxins/dynabolts.
IF TIMBER - wood screw #20 or similar (min. 50mm)
Attach the bracket and C-Rail with supplied pins
(Fig. 18)
.
WARNING:
Make sure concrete, brick wall or
timber lintels are solid and sound so as to form a
secure mounting platform.
Step 11 - Secure the Powerhead to the Ceiling
Secure the perforated angle (not supplied) to the
ceiling above where powerhead’s mounting holes
will be. See
(Fig.19)
for a representative mounting.
Connect the powerhead to the ceiling mounted
perforated angle with M8x20mm screws and nuts.
Strips should not extend more than 18mm below
centre of powerhead mounting holes
(Fig. 19)
.
Step 11.1 - Alternative Mounting Option
The opener can be fastened to the roof by driving a bolt
through the C-Rail into a structural timber support. The
bolt head’s height must not exceed 6mm
