11. Avoid Foreign Matter and Water Hammer
Do not install in locations in the piping where foreign matter accumulates or
where impact from water pressure (water hammer) occurs.
12. Piping Gaskets
Be careful that the piping gaskets do not protrude outside the inner bore of the
flange.
The type of medium being used and the temperature must be taken into account
in order to select a gasket of a suitable material.
13. Air Line Blowdown/Purge
Before connecting the air lines for the motive air that is to be piped to the
actuator, blow out the air in the lines to purge any dirt, foreign matter, oil or water
from inside of the piping.
14. Quality of Motive Air
Supply to the actuator only clean air that does not contain water, oil or foreign
matter.
To prevent malfunction due to contamination of the air supply, installation of the
optional air filter regulator (5µ filter) and mist separator (0.3µ filter) as a set is
recommended.
If air quality results in operation failure, the entire actuator unit (including the
integrated positioner) must be replaced.
If there is a problem in operation, determine the cause using the “Troubleshooting”
section in this manual.
