4.5 FINAL INSTALLATION OF THE OPERATOR

4.5.1 Mechanical fi xing
Fix both ends of the operator to the respective mountings.
Front fi xing
Smear the front anchoring pin of the ball-joint and the rod with
graphitized grease.
Position the end of the rod into the front mounting (C11 pos. 4). Fit the
locking pin (C11 pos. 5) and fi x with the snap rings.
Rear fi xing
Fix the operator to the rear mounting using the fork pin (C18 pos. 3)
and the relevant lock nut (C18 pos. 4).
With the gate leaf fully closed, re-check that the rod comes out from
the operator of the defi ned measure.

4.5.2 Checking the motion

!
Warning
• When the mounting is completed, neutralize the hydraulic
lock (if present in the operators) by turning the correct key
through 180° counter-clockwise, and move the gate-leaves
manually to check on the smoothness of the movement; this
should be done very slowly, otherwise the operators will take
in air and, consequently, will have to be bled.
• Open and close the gate leaf to check that the operator can
move freely without rubbing and without going against either
the gate leaf or the gate post.
• After making the checks, reset the hydraulic lock by turning
the release key fully in a clockwise direction.

4.5.3 Electrical connection

Make the electrical connection according to the wiring diagram (D1)
- see paragraph "System electrical connection".
Connect the supplied capacitor (B4 pos. 12) to the electric control
unit according to the wiring diagram of the unit itself.
4.5.4 Fitting the protection casing and removing
the bleed screw
Fit the protective casing (E1 pos. 1) to rod and insert into the
operator.
Hold the casing bottom (E2 pos. 2) in position with a cross-head
screwdriver (E2 pos. 3).
Fit the push-on cover (E3 pos. 2) on to the protective casing (E3
pos.1).
Tighten the fi xing screw of the protective casing (E4 pos.1).
On completion of the assembly, remove the bleed screw (E5 pos. 4)
using a CH7 hexagonal wrench.
