How to Exchange
Solenoid valve
•Loosen 3 set screws (hexagonal socket head
cap screw M3 X 31) and pull solenoid valve
out vertically, otherwise it may cause damage
to the solenoid valve. Never remove a valve
at an angle.
•When mounting solenoid valve onto the base,
plug pin ass'y (base-side) into
receptacle ass'y (body-side) vertically.
