S700H HYDRAULIC RELEASE KIT
2. INSTALLATION PROCEDURE
This operation refers to the installation of the hydraulic release
system on the S700H operator and it must be considered as an
additional procedure of the operator installation sequence
indicated on the manual.
The dimensions concerning the box position must correspond
to those given in Fig. 2.
Release the automated system
Place the components of the grooved coupling kit as shown
in Fig. 3 and Fig. 4, taking care to observe the position of
the reference on the grooved coupling; weld the U-shaped
profile to the grooved coupling as shown in Fig. 4
Continue installation according to the instructions of the
S700H operator, especially as far as its position in the box
is concerned
After having installed the operator, fasten the release
system using the two supplied M8 screws (fig. 5 ref.
/
)

1. DESCRIPTION OF COMPONENTS
If you are installing the release device on an already
existing system, equipped with a pre-modification box,
the fastening holes could be absent.
In such a case, refer to the template supplied with
the release system and drill two M8 threaded holes
necessary for the fastening operation (ref. chapt. 4).
Remove the bleed unions on the operator, then connect
those supplied with the release system (Fig. 5 ref.
0
and
Fig. 1 ref. from
3
to
6
)
Lock the operator again.

Air in the hydraulic circuit causes irregular operation of the
automated system that shows up with an incorrect movement
of the leaf and excessive noise during operation.
To solve this problem, operate as follows:
1) Command an opening movement of the gate.
2) During the leaf movement, loosen the opening bleed screw
(Fig.6 ref.
/
)
3) Let air come out from the hydraulic circuit through the bleed
screw until non-emulsified oil comes out.
4) Tighten the bleed screw before the operator ends the
opening cycle.
5) Command a closing movement of the gate.
3. BLEEDING THE AUTOMATED SYSTEM
6) During the leaf movement, loosen the closing bleed screw
(Fig.6 ref.
0
)
7) Let air come out from the hydraulic circuit through the bleed
screw until non-emulsified oil comes out.
8) Tighten the bleed screw before the operator ends the closing
cycle.
9) Repeat the operations, if necessary.
10) Restore the oil level until it is just under the cap, using oil
supplied with the kit (Fig. 7 ref.
/
).
4. USING THE DRILLING TEMPLATE
You need to use the drilling template whenever you need to
fit the hydraulic release kit to an already existing automated
system, removing thus the previous mechanical release
system.
In such a case, the carrying box has no fastening holes for the
hydraulic release system.
Remove the old release system
Install the new grooved coupling kit (refer to chapter 2)
Fold the template along the pre-marked reference (Fig.9
ref.
/
)
Match the curved profile of the template with the coupling
kit (Fig.9 ref.
0
), mark the position of the two holes on the
box (Fig.9 ref.
1
).
Drill pre-holes, diameter Ø 6.5mm (Fig.9 ref.
2
)
Thread the pre-holes with a tap M8 (Fig.9 ref.
3
)

5. USING THE RELEASE SYSTEM
To release the operator, remove the plastic cover, insert the
key and turn the release lock
counter-clockwise
for about one
turn. (Fig. 8 ref.
/
)
To lock the operator again, turn the release lock clockwise until
reaching the stop point,
do not force
(Fig. 8 ref.
0
)

IMPORTANT! Protect the operator in a suitable
way during the drilling operation in order not to
damage it, otherwise remove it from the box.
If you remove it, refer to the instruction to synchronise
leaf and operator during the assembly.
