Laying the foundation plate - Fixing to the floor
If the floor is in cement (or similar material) it is possible to fix the plate directly to the
ground:
1 - Obtain suitable fixing systems, normally on the market, steel pressure plugs (figure 11
-ref A) or anchorage with expansion straps (figure 1 -ref B) to be inserted using a mallet.
2 - Respecting the measurements indicated previously, trace the drilling points using
the plate as a reference, make 4 holes measuring 10 mm in diameter and fix the plate.
Make sure that the threaded bar projects by at least 25mm as indicated in figure 10.
3 - In some cases (rack already installed, possible water stagnation, etc) it is possible
to ix the plate in a raised position with respect to the floor by a maximum of 20 mm,
positioning 4 nuts and the relative washers under the plate as indicated in figure 12. In
this case, the pins must project from the ground by at least 45mm.
Check that the floor is well-levelled and suitable for fixing via plugs.
Independently from the type of pre-selected fixing, the plate must result
well-fixed, perfectly levelled and parallel to the leaf.f

Fixing the gear motor
To fix the motor reducer to the plate, with reference to fig. 13, proceed as follows:
1 - Remove the two screw-cover sumps C.
2 - Place the gear motor on the plate, making sure that the threaded bars enter the holes.
3 - Block the gear motor using the 4 washers R and the 4 bolts D.
4 - The slots F allow to regulate the distance of the motor with respect to the leaf.

Fixing the rack
The rack, appropriately fixed to the leaf, transforms the rotary movement of the gear
into the linear movement of the leaf.
Before fixing the rack, it is necessary to release the gear motor, proceed as follows:
1) Turn the circular cover by 180°, in a way to view the triangular pin.
2 - Insert the release key FRD.3 and turn it clockwise until a certain resistance is felt
(Fig.13).
About 15 complete rotations of the key are necessary
3 - The gear is now released and free to turn.

Now fix the rack:
1 - Take the leaf into the completely open position.
2 - Place the first tract of the rack on the gear.
Considering the measurements indicated in figures 3a and 3b, mark the first drilling
point. Block the rack temporarily, using a clamp for example (Fig.15).
3 - Drill and block the first fin of the rack using the screw and the washer as indicated
in figure 16.
