When installing a positioner, please ensure to read and follow safety instructions.
➢
Any input or supply pressures to valve, actuator, and / or to other related devices must be turned
off.
➢
Use bypass valve or other supportive equipment to avoid entire system
“shut down”.
➢
Ensure there is no remaining pressure in the actuator.

The positioner has two vent covers. The vent cover of them which is indicated on the below is for
exhausting internal air and draining internal condensation water. When installing the positioner,
make sure the vent cover must be facing downward. Otherwise, the condensation water could
