Shut-off valve regulation:
The adjustment is carried out as follows:
• Remove the cap 1
• Turn the cap over and use the impression on the other side to rotate the
shut-off valve 2 reaching the completely open position.
• Use a 4mm Allen key to screw the regulator 3 in completely..
The shut-off valve is now ready to be set:
• Unscrew the regulato 3 by the desired number of turns.
• Insert the cap again.
The cap can also be lead-sealed in the position obtained by using the holes
located on the wings  in order to secure it directly to the collector, thus
preventing any tampering.
Note: When finished testing the system, reduce the pressure within the
collector (by using the discharge valve) before opening the shut-off valves
or flow-rate meters.

7.3 Shut-off valve regulation with flow-rate meter.

Regulation
The adjustment is carried out as follows:
1. Lift the ring nut
off valve is opened completely.
2. Lower the ring nut
correct flow rate is obtained (indicated directly by the meter).
3. Lift the ring nut
tioning of the ring nut.
Note: All the above operations must be carried out manually.
The ring nut can also be lead-sealed in the position obtained by using the
holes located on the wings © to secure it:
- directly to the collector, thus preventing any tampering;
- to the meter, leaving the possibility of intercepting without changing the
maximum opening calibre set.
Cleaning the window
- Turn the ring nut
- Remove the window by unscrewing it from the regulator
- Clean the window and then screw it back on to the regulator
- Turn the ring nut
completely.
