10. CARRYING BOX INSTALLATION
10.1. The hole which contains the carrying box must have the
approximate dimensions mentioned in Fig. 33.
For a correct placing, it is obbligatory to follow closely the quote
of 2,16 inches which corresponds to the minimum distance of
the rotation axis from the pillar.
Fig. 35
10.3. Before concreting the carrying box, use a level to make it
perfectly horizontal to the ground (Fig. 35) and perpendicular to
the axis of the gate (Fig. 36).
The axis of the upper hinge of the gate must correspond exactly
to the axis of the carrying box shaft.

a) command opening of the gate;
b) during opening of the gate, loosen the air bleed screw related
to opening (Fig.32-rif.A);
c) release any air from the hydraulic circuit until non-emulsified
oil appears;
d) tighten the air bleed screw before the operator completes the
opening cycle;
e) command closing of the gate;
f) during closing of the gate, loosen the air bleed screw related to
closing (Fig.32-rif.B);
g) release any air from the hydraulic circuit until non-emulsified
oil appears;
h) tighten the air bleed screw before the operator completes the
closing cycle.
It is recommended to repeat this operation on both air bleed
screws at intervals of 2/3 opening and closing cycles.
i) Replace the oil from the oil filler cap. Any top-ups should be
performed only with oil SEA 0x29 (supplied).
10.2. Inside the excavated pit you have to plan:
- rain water drainage;
- a water waste pipe in flexible plastic of about 1,57 inches of
diameter to put inside the provided hole of the box before it is
concreted (Fig. 34). It must be brought to the drain of the
sewer line;
- a sheath of about 1,25 inches diameters for the passage of
hydraulic tubes must be brought to the proximity of the
hydraulic unit box (Fig. 34).
