Connecting the piping

Ensure that the metal piping attachments are tightened to the required torque (refer to the table below).

If the tightening torque is exceeded, the product can be broken. If the tightening torque is insufficient, the
fittings may become loose.

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.

Avoid any sealing tape from entering inside the piping.

Ensure that there is no leakage from loose piping.
