Piping
When connecting piping to the product, a spanner should be used on the metal piping attachment only.
Using a spanner on other parts may damage the product.
In particular, do not let the spanner come into contact with the M8 connector.
The connector can be easily damaged.

If the tightening torque is exceeded, the product can be broken. If the correct tightening torque is not
applied, the fittings may become loose.
Avoid any sealing tape getting inside the piping.
Ensure there is no leakage from loose piping.
