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 a vent cover to exhaust internal air and drain internal condensation water.
When installing the positioner, make sure the vent cover must be facing downward. Otherwise,
the condensation water could cause damages to PCB.
