Roof installation
1. Extend the vertical centre line (2) up in
the roof.
2. Centre the bracket (1) on the extension
of the vertical centre line, no more than
150 mm from the wall. The arrow on the
bracket should point towards the drive
unit. Mark the position of the holes for
the bracket (5).
3. Drill holes with a 4.5 mm drill and screw

top edge of the door leaf and near the
centre line, see figure. Allow the guide to
rest on the fibreboard.
3. If the door leaf touches the carrier when
the door is open, pull down the release
arm to release the inner and outer part

If the space above permits it can be easier
to use a 25 mm thick spacer (1) to adjust the
gap between door leaf and guide.
Mounting of the door opener
1. Bend the suspension rod (1) so that the
bent part is flush with the surface of the
roof.
2. Measure the gap from the bracket over
the door opening to the screws (4) for the
