on-off valves
Important:
the on-off valves are “normally closed” solenoid valves; the
valve body has three F G1/8” connections (see the fi gure on the side).
Remember that the water inlet is the hole in the centre, while the two
side holes are the two outlets available:
•
individually, closing the outlet that is not used with a M G1/8” plug;
•
together if this simplifi es the water connections.
3.
remove the electrical connector;
4.
disconnect the pressurised water supply pipe;
5.
