FITTING THE MANUAL OVERRIDE
LEVER MECHANISM
Drill two 1/4” holes in the door track or frame in
a position at least 2” higher than the fully
extended position of the Outer Cable Bracket to
allow flexibility of movement for the Bowden
cable. Use the supplied M5 screws and flange
nuts to secure the Outer Cable Bracket to the
door track or frame (Pic 8).

Hang the Manual Override Lever hook on the
end of the inner cable with the lever in the
upright position.
Mark the mounting hole positions for the lever
on the door track or frame – the supplied chain
may be needed to position the lever within 6
feet of the floor. Drill two 1/4” holes and secure
the lever using the M5 screws and flange nuts
supplied (Pic 9).

Place the hook in the cable D-‐shackle or a
convenient link of the chain and ensure that the
lever is slightly above horizontal when all of the
tension has been taken up (Pic 10).

It is important that sufficient tension is achieved
to compress the override release spring and
ensure that the drive belt does not slip on the
motor pulley. Screw the hook in or out so that
the lever requires reasonable hand pressure to
lock it into place (Pic 11).
This procedure must
be repeated once the calibration has been
completed
and on subsequent service visits to
allow for the bedding in of the V-‐belt.

FITTING THE CONTROL BOX
Use the Control Box template on the back of
these instructions to mark the hole positions
and mount the box on the wall using suitable
fixings no larger than 3/16” diameter (Pic 12).
