may not be able to drain.
z Mounting this device
For details on how to mount this device to a product on the secondary side, see the user’s
manual for the relevant product.
If the relevant user’s manual provides mounting instructions, follow them instead of this
document. Also, note that the tightening torques for screws and nuts provided in this
section onward are rough guides. Determine the appropriate torque depending on the
usage conditions.
Mount the pressure regulator on the mounting plate using two or more of the four M4
screws (
Fig. 1-1
(3)) in the top of the pressure regulator. The RA1B-2 and RA1B-3 can also
be mounted using the two M6 screw holes (see
Fig. 2-6
) in the pressure regulator body.
Note
• The M6 screw holes are covered with cover seals. Remove them before use. No M6
screws are included with this device. Please obtain them separately.
• For the dimensions of each mounting part, see the specifications in Appendix A or
the following documents.

tighten the M4 screws, and then adjust the pressure.
