Operating Environment
1. Perform maintenance in accordance with the
procedures in the instruction manual.
Improper handling can cause damage or malfunction of equip-
ment and devices, etc.
2. Demounting of the product
1. Shut off the fluid supply and release the fluid pressure in the
system.
2. Shut off the power supply.
3. Demount the product.
3. Low frequency operation
Switch valves at least once every 30 days to prevent
malfunction. In addition, perform maintenance inspections once
every six months to ensure optimum performance.
Warning
1. Filters and strainers
1. Be careful regarding clogging of filters and strainers.
2. Replace filter elements after one year of use, or earlier if the
amount of pressure drop reaches 0.1MPa.
3. Clean strainers when the amount of pressure drop reaches
0.1MPa.
4.
Flush drainage from filters periodically.
2. Storage
In case of long term (approx. one month or more) storage after
use with water, first thoroughly remove all moisture to prevent
rust and deterioration of rubber materials, etc.
Caution
1. As a rule, use electrical wire of 0.5 to
1.25mm² or more.
Furthermore, do not allow excessive force to
be applied to the lines.
2. Use electrical circuits which do not generate
chattering in their contacts.
3. Use voltage which is within ±10% of the rated
voltage. In cases of a DC power supply where
emphasis is placed on responsiveness, stay
within ±5% of the rated value. The voltage
drop is the value in the lead wire section con-
necting the coil.

Electrical Circuits
1. Do not use valves in atmospheres of corrosive
gases, chemicals, salt water, water or steam, or
where there is direct contact with same.
2. Do not use in explosive atmospheres.
3. Do not use in locations subject to vibration or
impact.
4. Do not use in locations where radiated heat will be
received from nearby heat sources.
5. Employ suitable protective measures in locations
where there is contact with water droplets, oil or
welding spatter, etc.
