• Unscrew two steel angle irons with length adjustment holes (1) and

screw onto ceiling bracket (2) as shown.

• Dismantle drive shaft (1):

Pull out clip fixing (2) and remove bolt (3).

Installation

Use a non-slip, stable stepladder!

If the distance between the ceiling and the lower edge of the

C-rail is greater than 245 mm, then extend the suspension

bracket (with perforated steel strip).

• Determine door's highest up-position (THP):

Open door and measure smallest clearance (min. 35 mm) between

top edge of door and ceiling. The distance between HDP and the

lower edge of the C-rail must be between minimum 5 mm and

maximum 65 mm, whereby the push rod must be at an angle of

max. 30° (see fig. 17)!

Please note that this distance might be smaller, if the door

handle is located at the centre of the door. Ensure that the door

movement is not obstructed.
