•Fit a housing fixing bracket at the end of the head profile,
opposite the motor unit, using the supplied screws and plates
(fig.23).
•Fit the second housing fixing bracket slightly off-centre of the
head profile, to enable you to make the door-centre
adjustments.
•Secure the bracket supporting the internal release knob to
the other end of the head profile (on the motor unit side), as
shown in fig. 24.
