Connect the components with fork coupling as follows:
- Apply O-ring lubricant.
- Position the O-ring ON THE MALE CONNECTION OF ALL THE COUPLINGS (make
sure that the position is correct).
- The couplings shown are indicative.
The maximum operating pressure of the valve is indicated in the technical data
sheet of the product.
ONLY after all the hydraulic connections of the circuit to the relevant pipes have
been made, put the system under pressure ONLY WITH CLEAN WATER FIRST to
make sure that the connections are not leaking.
If, for any reason, the pipes leak at connection points, apply PTFE tape to improve sealing.
