Piping Method

When connecting the piping to the product, do not rotate the switch. Apply a spanner to the metal part of the
piping port to turn the fitting."
Using a spanner on other parts may damage the product.
Specifically, make sure that the spanner does not damage the M12 connector.
This will damage the connector.
Apply a tool
Turn the pipe
Ensure that the piping is tightened to the required torque.
The tightening torque for connection threads is shown in the table below.
Nominal thread size
Rc(NPT)3/8
Rc(NPT)1/2
Rc(NPT)3/4
Rc(NPT)1
If the tightening torque is exceeded, the product can be damaged. If the tightening torque is insufficient, the
piping may become loose.
The product body is made of resin. Do not apply direct stress, vibration or impact during piping to avoid
malfunction, damage or water leakage. Never mount the product in a location that will be used as a
scaffold.
Affix the piping as close to the product as possible (both before and after the product) to avoid direct stress,
vibration or impact.
If the stress, vibration or impact cannot be reduced, affix the product at multiple locations.
