Chapter 3 Operation
This chapter describes how to start and stop this device and how to adjust the pressure.
If the user’s manual for the product on the secondary side provides instructions on how to start and stop operation
and how to adjust pressure, follow them instead of the instructions in this document.
„
How to Start Operation
(1) Change the pressure to the lowest setting before supplying air to this device. (See
„
How to Adjust the Pressure
.)
(2) Check the state of connections on the secondary side of this device, and make sure
that there is no chance of devices being damaged or malfunctioning due to a release
of unadjusted air pressure.
(3) Supply air to this device, and adjust the pressure by following the prescribed
procedure. (See
„
How to Adjust the Pressure
.)
(4) Check that the product on the secondary side functions normally. If so, the procedure
is completed.
„
How to Stop Operation
(1) Check the operation of the device on the secondary side, and make sure that there is
no chance of it being damaged or malfunctioning due to fluctuations in air pressure
output before stopping this device. Close the shutoff valve, if any, on the secondary-
side pipe.
(2) Change the pressure of this device to the lowest setting. (See
„
How to Adjust the
Pressure .)
(3) Stop supplying air to the primary side of this device.
(4) After tightening the slotted screw or pressure adjustment knob slightly, change
the pressure to the lowest setting again and then release residual pressure from the
primary side.
(5) If the residual pressure cannot be released in one operation, repeat operation (4)
several times.
(6) Check for any residual pressure and then confirm that there is nothing abnormal with
this device or the air piping. This completes the procedure.
Note
• If the piping is laid out in such a way that residual pressure on the primary side is
released when the air supply is stopped, steps (4) and (5) can be omitted.
„ How to Adjust the Pressure
If this device is attached to a product that does not always expel air and the piping capacity
of the secondary side is large, it will take some time for the air pressure to reach the
specified pressure. Adjust the pressure after closing the pipe at a position immediately after
the pressure regulator, or check the pressure after sufficient time has passed.
Before, after, or during pressure adjustment, check for air leakage from the seals and piping
connection ports. If the pressure fluctuates drastically because of a sudden operation, this
device may be damaged or malfunction, or air may leak.
