timber lintels are solid and sound so as to form
a secure mounting platform.
Step 9 - Determine the Door’s Centre

above the door and on top of the door.
Draw two lines 21.5mm either side of this b. (Fig. 17).
Step 10 - Prepositioning the Opener
Raise the door to open position.a.
Rest the opener on the top edge of the door with end b.
of the C-Rail against the wall (Fig. 18).
Support the powerhead level with the lowest point of c.
the open door (Fig. 18).
NOTE: Do not slide C-Rail along the face of the door.
Step 11 - Mounting the C-Rail
Close the door slowly. The C-Rail will be elevated by a.
the top edge of the door as it moves.
Stop the door when it is at its highest point of travel. b.
Allow 25mm additional height for clearance between
the door and the track (Fig. 19).
Support the C-Rail in this position and close the doorc.
The height determined in Step 11(b) will be the height d.
at which to mount the wall bracket.
Centre the bracket along the line determined in Step 9.e.
Using the bracket as a template, mark a minimum f.
of two holes and drill with appropriate size bit. For a
more secure fitting, the wall bracket can be anchored
using more than two holes.
Secure the bracket to the wall using: g.
IF CONCRETE OR BRICK - 10mm dynabolts.
IF TIMBER - wood screw #20 or equivalent
(minimum 50mm long).
Attach the wall bracket to the C-Rail with the 90mm h.
long clevis pin (Fig. 20) and secure by a snap pin.
Step 12 - Securing the Powerhead to the Ceiling
Secure the perforated angle (not supplied) to the a.
ceiling above where powerhead’s mounting holes will
be. See (Fig. 16) for a representative mounting.
Connect the powerhead to the ceiling mounted b.
perforated angle with M8x20mm screws and nuts.
