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 7 - 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. 14).
Step 8 - 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. 15).
Support the drive unit level with the lowest point of 
the open door (Fig. 15).
NOTE: Do not slide rail along the face of the door.
Step 9 - 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. 16).
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. 12).
WARNING:  Make sure concrete, brick wall or 
timber lintels are solid and sound so as to form a 
secure mounting platform. 
Step 10 - Secure the drive unit to the Ceiling
Secure the perforated angle (not supplied) to the 
ceiling above where drive unit’s mounting holes will 
be. See (Fig.19) for a representative mounting.
Connect the drive unit to the ceiling mounted 
perforated angle with M8x20mm screws and nuts. 
Strips should not extend more than 18mm below 
centre of drive unit’s mounting holes (Fig. 13).
Step 10.1 - 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 (Fig. 17).
