"Piping" on page 5 when using sealant tape.
* Position adjustment of the round type pressure gauge
and digital pressure switch
Adjust the round type pressure gauge and digital pressure
switch by tightening the thread. Do not unscrew the gauge
as air leakage may occur.

pressure switch on the back of the regulator
The pressure gauge connection port on the front of the
regulator with round type pressure gauge and digital
pressure switch is not plugged. When mounting the round
type pressure gauge or digital pressure switch on the back
