3. INSTALLATION
3.1

Preliminary checks

Check that the structure is sufficiently sturdy and that the hinge pivots are properly lubricated. Provide an opening
and closing stop.
Geared motor installation
Unless otherwise specified, all measurements are expressed in millimetres.
3.2 Check the mounting dimensions (fig. 3) as a function of the distance between the wing hinge pivot and the
edge of pillar [C] and of the desired opening angle [D].
3.3 The geared motor is normally supplied in the right-handed version. To convert it to the left-handed version,
proceed as follows (see from Figs. 6 to 10):
- Loosen the motor clamping screws (Fig. 6).
- Remove the motor and the reduction gear plug, and slide out the motor cable (Fig. 7).
- Rotate the reduction gear by 180 degrees (Fig. 8).
- With the reduction gear in this position, fit in the motor and the plug and route the cable in (Fig. 9).
Attention: Take care to mount the motor so that the cable comes to be on the opposite side of the
release.
- Fit in and secure the motor clamping screws (Fig. 10).
3.4 Secure the tail bracket [14] (Fig. 4) according to dimensions [A] and [B] (shown in Fig. 3) selected as a function
of the desired opening angle [D]. The tail bracket is provided with holes to facilitate mounting (fig. 5).
Note: The installation measurements given in the table in Figure 3 permit to select the values for [A] and [B]
according to the desired opening angle and with reference to existing room and spaces. Compliance with the
measurement given in the table is recommended, modifying the brackets provided, if so required.
In order to ensure smooth gate movement, check that measurements [A] and [B] are the same. Increasing [A]
reduces the coming up speed during opening. Increasing [B] diminishes the coming up speed during closing
and improves burglar-proofing. Reducing [B] increases the extent of gate opening. Measurements [A] and [B]
must in any case be compatible with the useful travel of the piston so that; if [A] is increased, [B] must be
diminished and vice versa.
