Mounting & Adjustment
Maintenance
1. Set the regulator while checking the
displayed values of the inlet and outlet
pressure gauges. Turning the knob
excessively can cause damage to the
internal parts.
2. The pressure gauge included with
regulators for 0.02 to 0.2 MPa setting is for
up to 0.2 MPa use. Exceeding 0.2 MPa of
pressure can damage the gauge.
3. Do not use tools on the pressure regulator
knob as this may cause damage. It must
be operated manually.
1. Be sure to unlock the knob before
adjusting the pressure and lock it after
setting the pressure.
Failure to follow this procedure can cause
damage to the knob and the outlet
pressure may fluctuate.
• Pull the pressure regulator knob to unlock.
(You can visually verify this with the “orange
mark” that appears in the gap.)
• Push the pressure regulator knob to lock.
When the knob is not easily locked, turn it
left and right a little and then push it (when
the knob is locked, the “orange mark”, i.e.,
the gap will disappear).
2. A knob cover is available to prevent
careless operation of the knob. Refer to
page 14-2-6 for details.
1. Replace the element every 2 years or
when the pressure drop becomes 0.1
MPa, whichever comes first to prevent
damage to the element.
