- Do not remove a dust-proof cap provided to piping port before piping work starts.
- Avoid excessive tightening for joint. (The threaded area can be damaged.)
- Check the connection locations, air pipe sizes, and screw types with the approved
drawings and other documents for the product. Then lay the air piping.
- Use dehumidified and dust-removed clean operation air. When using highly dry air at a
dew point of -40 or less, please consult us separately.
- If the actuator is used in an environment below 5˚C temperature, its operating fluid must
be free from the water and moisture contained in it because of possible problems due to
the freeze.
- Steel pipes must always be of the plated.
- Before installing an actuator in pipeline, flash the inside of pipeline completely.
- When connecting the air piping, be careful not to let foreign matter inside the piping.
- Threaded area of a pipe must be free from the sharp edges and burr.
