How to change piping connection specifications (4GA/B R)
Observe the tightening torque of the mounting screws when replacing the plate or the fitting adaptors
attached to the body, when changing the body piping specifications and base piping specifications, or
when changing the push-in fitting and internal thread specifications of body piping type. Insufficient
tightening causes problems such as air leakage.
