Piping for the One-touch fitting

•Insert the tube all the way into the fitting
so that it cannot be pulled out.

•Insertion with excessive force can cause
damage.

•Ensure there is no leakage after piping.

•Use the product within the specified
operating pressure and temperature range.

Troubleshooting

∗: If the error cannot be reset after the above measures are taken, then please contact SMC.

Piping

•

Never mount the product upside down.

•The straight piping length shall be 8 cm or longer.
O

therwise, if a straight section of piping is not installed, the accuracy varies by

approximately

±2%F.S.

•

Avoid sudden changes in the piping size on the IN side of the product.

•Do not release the OUT side piping port of the product directly to the atmosphere
w

ithout the piping connected.

If the product is used with the piping port released to atmosphere, the accuracy may vary.

Piping for the metal attachment

•Tighten to the specified torque. Refer to the table below for the required torque values.

•Use a suitable spanner for the appropriate torque. Do not use a spanner 40 cm or
longer.

•If the tightening torque is exceeded, the product can be broken.
If the tightening torque is insufficient, the fitting may become loose.

•Avoid any sealing tape getting inside the flow path.

•Ensure there is no leakage after piping.

•When mounting the fitting, a spanner should be used on the metal part (attachment) of
the fitting only.
Holding other parts of the product with a spanner may damage the product.
Specifically, make sure that the spanner does not damage the connector.

may change depending on the operating environment. Therefore, check the safety
of the whole installation before operating the product.

Defaultsettings

Thedefault settings are shown below.
When the flow exceeds the set value [P_1], the switch will be turned ON.
When the flow falls below the set value by the amount of hysteresis [H_1] or more, the
switch will turn OFF.
