WARNING
: Make sure concrete, brick wall 
or timber lintels are solid and sound so as to 
form a secure mounting platform. 
Step 9 - 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. 16).
Step 10 - Prepositioning the Opener
Raise the door to open position.
Rest the opener on the top edge of the door with end 
of the C-Rail against the wall (Fig. 17).
Support the powerhead level with the lowest point of 
the open door (Fig. 17).
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 
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. 18).
Support the C-Rail in this position and close the door.
The height determined in Step 11(b) will be the height 
at which to mount the wall bracket. 
Centre the bracket along the line determined in Step 9.
Using  the  bracket  as  a  template,  mark  a  minimum 
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: 
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 
long clevis pin (Fig. 19) and secure by a snap pin.
Step 12 - Securing the Powerhead to the Ceiling
Secure  the perforated  angle (not  supplied) to  the 
ceiling above where powerhead’s mounting holes will 
be. See (Fig.15) 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. 15).
WARNING
: The opener must be securely 
fastened to structural supports, otherwise 
opener failure may ensue causing serious 
personal injury and/or property damage.
