Fastening the opening system to the leaf
Connect the actuator to the hook console
mounted in the vent leaf.
To do so, remove the pin and pull the lower pin
out of the hook console.
Perform the installation process in reverse
order, forcing the pin additionally through the
two nylon bushings and the actuator eyebolt.
Fig. 37 Connecting the actuator to the hook console.
Then, depending on the type of control, connect the system to the installation according to chapter
8 and make the adjustment according to chap. 7.

Mounting of the leaf glazing
It may happen that the dome glazing, e.g. for logistical reasons, is delivered separately. In such case,
the domes should be fitted to the vent leaf on site, preferably after the vent has been assembled, as
follows:
1.
remove the pressing frame (unscrew sheet metal screws 5.5x32 with EPDM washers);
2.
check the condition of the PES gasket on the support frame (clean it of dust);
3.
separate the polycarbonate sheet from the dome with the supplied PES gasket - glue around
the perimeter (see figure below);
4.
insert the pressing frame;
5.
screw in screws 5.5x32 with EPDM washer, while pressing the frame from above.
The multi-chamber polycarbonate glazing is supplied pre-assembled.
Replacement of the glazing, if any, should be made by reversing the steps described in points 1 - 5
above. If the glazing is replaced again, it may be necessary to replace the standard screws with larger
ones (e.g. 6.3x32).
If the pressing frame comes loose, loosen the fixing screws slightly and then screw them in one by one
while pressing the frame from above.
