■
Align the fluid flow direction to the direction
indicated on the body when connecting the pipes.
■
Fitting tightening with 4S, 4RM port size (hydrogen/
helium model).
1
Fitting tightening method
4RM (1/4" JXR male fitting)...when the gasket material is
nickel/SUS316
Tighten the nut with fingers until the gasket contacts the
bead surface, and then tighten another 1/8 turn with a tool.
4S (double barbed fitting)...Confirm that the front ferrule,
back ferrule and nuts are properly attached, and then
insert the tube until it contacts the back of the body.
Tighten the nuts as far as possible with fingers, and then
tighten 1 1/4 turn with a tool.
■
Before installing the piping, clean out the pipes
using an air blower to remove all foreign matter
and chips from the pipes.
The rectifier or platinum sensor could be damaged
if foreign matter, cutting chips, etc., should enter.
■
When installing this product on piping, refer to the
torque below so that excessive screw-in torque or
load torque is not applied to the connection port.

Mounting, installation and adjustment
■
When connecting pipes, wrap sealing tape in the
opposite direction from the threading, from the
inside position to within 2 mm from the pipe end.
●
If sealing tape protrudes from the pipe threads, it could be
cut when screwing the bolts in. This could cause the tape
to enter the solenoid valve, causing failures.
When using a liquid sealant, make sure to keep it away
from resin parts
Please be careful. Otherwise resin parts could be
damaged, which is dangerous.
■
Make sure that no sealing tape or adhesive enters
the pipes when connecting the piping.
CAUTION
2. Piping
■
If the piping is removed once, sealant may remain
on the thread part.
When repiping, remove the remaining sealant.
■
Be sure to connect a fitting even when using the
stainless steel body with the OUT side opened.
The port filter could come off.
■
When the resin body is used, do not bend the tube
near the push-in fitting. If stress is applied to the
tube near the push-in fitting, insert an insert ring into
the tube, and connect the tube to the push-in fitting.
■
When the resin body is used, securely insert the tube,
and make sure that it cannot be pulled out. Cut the
tube at a right angle with a dedicated cutter before use.
■
After piping, check that there are no gas leaks.
■
When using this product for oxygen gas, take
special care with the points below.
●
The piping work should be performed by an expert in the
handling of oxygen gas.
●
Use piping with oil-free processing.
●
Make sure to remove dirt, burrs, etc., in the piping before
installing the product.
●
Install a filter on the primary side of the product.
■
Do not install regulator/solenoid valve, etc., immediately
before this product. Generated drift may cause errors.
Provide a straight piping section if required.
■
Although the mounting is "unrestricted in vertical/
horizontal direction", the flow rate may vary
depending on difference in the mounting orientation
or piping conditions.
■
Do not install multiple bodies in close contact. The mutual
generation of heat could cause the product body's
temperature to rise, hastening changes in characteristics
or in the resin material. When using the products in a
row, set intervals of distance of 10 mm or more.

■
Hook a wrench to the stainless steel body when
tightening pipes so that force is not applied to the
resin section.
