Piping method:
When piping a product, use a wrench to pipe the metal parts (pipe fittings) that
are integrated with the piping part.
If you use a wrench in other parts, the flow switch may be damaged.
In particular, no spanner can be used on the M12 connector.
Otherwise, the connector may be damaged
If the switch is tightened outside the torque range, it may be damaged. If assembled
without a specified tightening torque, it may loosen the joint thread.
Installation of piping:
Please do not let the sealing
tape into the tube.
Piping connection:
Please do not relax and cause
liquid leakage.
Please strictly observe the safe torque value of piping:
Attentional collision
Fixed wrench
Fastening wrench (please refer to torque value)
