Step 9.
Determine the centre of the door and mark this
location on the wall above and on top of the door.
Then draw two (2) lines 21.5mm on each side of the
door. (Fig. 10).
WARNING: make sure concrete, brick wall or
timber lintels are solid and sound so as to
form a secure mounting platform.
Step 10.
Raise the door to open position. Rest the opener on
the top edge of the door with end of the pipe/tube
against the header wall and drive unit support level
with the lowest point of the open door. (Fig. 11).
NOTE: Do not slide opener tube/pipe on face of the
door when it is open.
Secure the opener to the ceiling above drive unit
mounting holes, with perforated angle (not supplied).
A representative mounting is shown. (Fig. 9) Connect
angle and drive unit with 2 flat perforated strips of
angle (not supplied) with M8 x 20mm screws, nuts and
washer. Strips should not extend more than 18mm
below centre of drive unit mounting holes. (Fig. 9).
Do not lock screws at this stage.
Step 11.
Close the door slowly. The opener pipe/tube 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.
(Fig. 12) Allow 25mm additional height for clearance
between the door and the track. Support pipe / tube in
this position and the close the door. (Fig. 12) This will
be the height to mount the wall bracket. Top of door
must not touch tube.
WARNING: the opener must be securely fastened
to a structural support of the garage. Failure
to fasten the operator correctly will lead
to possible opener failure causing serious
personal injury and/or property damage.
Step 12.
With the centre point of the door located, mark a line
through the centre of the wall bracket onto the header
wall (above the door). Using the bracket as a template
mark a minimum of two holes and drill with appropriate
size bit. If necessary the wall bracket can be anchored
using more than two holes for a more secure fitting.
If the wall bracket is mounted onto concrete or brick
wall, use M8 or 5/16” loxins or dynabolts. If mounted
onto wooden lintel or beam, use wood screws #20
or equivalent, minimum 50mm long. Attach the wall
bracket to the support pipe assembly with 90mm long
clevis pin (Fig. 13) and securely spring clip.
