ADJUSTMENTS
Air adjustment
The easily accessible micrometric screw device (A)
allows for finely tuned, stable and precise adjustment of
delivery air.
After loosening the crown (B), rotate the screw clockwise
to reduce throttle opening or, vice versa, rotate anti-
clockwise to increase it.

If a solenoid valve with a single adjustment device is
installed carry out adjustment as illustrated in figure 11.
MULTIBLOK VALVE ADJUSTMENT
1 1st/2nd stage delivery adjustment lock screw
2 Stabilizer adjustment
3 Protective cover for initial fast-start adjustment device
4 2nd stage delivery adjustment
5 1st stage delivery adjustment
To adjust the 1st/2nd stage delivery loosen screw (1).
Turning (4) and (5) anticlockwise increases the delivery.
Turning clockwise reduces the delivery. Once you have
carried out the necessary adjustment re-tighten screw
(1): To adjust the initial fast-start mechanism remove the
cover (3) and, using the rear of the cover as a tool, rotate
the pin.
ADJUSTING THE MAIN SOLENOID
To adjust initial delivery remove the protective cap, turn it
over and position it on the screw.
Screwing in reduces the flow rate. Loosening it, instead,
increases the flow rate.
To adjust the total flow rate loosen screw "C" by two or
three turns and then rotate the knob.
Rotating the knob clockwise reduces the flow rate while
rotating it anticlockwise increases it.
