(1) Mounting posture is unrestricted.
However, avoid positioning the coil side down, since foreign matter in the fluid
accumulates around the plunger and result in beat sounds and malfunction.
(2) Provide enough space for safe maintenance and troubleshooting work.
２．３ Piping method
a) When piping or re-piping, fix the product.
b) Fix and provide appropriate support to the piping, so that
the weight and vibration of the piping will not directly be
applied to the product.
c) When piping is finished and fluid is to be flown, supply
pressure gradually.
・f the piping is improper, the piping may disconnect or
the fluid may leak.
(1) Cleaning the piping
・ Before piping, flush the piping with compressed air 0.3MPa or more to remove
foreign material such as dust, metal powder, rust and sealing material.
(2) Removal of foreign matter
・ Foreign matter such as dust in the fluid causes malfunction and leakage.
To remove foreign matter, attach an appropriate apparatus to the primary side of
the product. When the fluid is air, attach a filter 5µm or finer. When the fluid is
water, attach a strainer 80 mesh or finer.
(3) Piping

・When piping a tube to a barbed joint, be sure to insert the tube
straightforward.
Choose tube that has inner diameter around φ４.
Confirm leakage and connection firmness before work, since
attaching force (retaining force) differs according to tube
material.
Do not apply excessive force such as pull, compression, and
bending after piping. External force of 0.2 N・ ｍ or more
applied to the barbed joint causes leakage or breakage.
(4) Sealing material
・ When using sealing material, make sure the sealing material do not enter the
piping. Also, make sure there is no external leakage. When taping seal tape to the
pipe thread, leave 1 to 2 threads at the tip without taping.
Also, when using liquid sealing material, leave 1 to 2 threads at the tip without
sealing material. Do not apply too much sealing material on the thread. Do not
apply sealing material to the internal thread (refer to figure 2.）.
