9. PRODUCT CARE AND MAINTENANCE
Under normal conditions, the electrical actuator must be checked in every 6 months. For
more hazardous conditions, it must be checked more frequently.
Before electrical actuator displaced from the system, the power on the electrical actuator
must be switched OFF and pressure in the pipe must be zero.
• Be sure about valve and actuator mounting is right.
• Be sure about all electrical wiring is isolated and wired regularly.
• Be sure about all screws are mounted and tightened up.
• Be sure about the parts in the electrical actuator is clean.
• Be sure about cable glands and blind plugs are mounted and dry.
• Be sure about if there is no humidity in actuator.
• Be sure about inner heater is working. The internal heater prevents the formation of
moisture inside the actuator and prevents the electronic parts from breaking down.
• Be sure about is manual hand wheel is operating.
• Be sure about actuator’s position indicator and valve position are correlate.
• Be sure about label is readable. If it is necessary request to change the label with more
readable one.
During both installation and maintenance be careful about sensitive inner parts.
They must not be damaged. Before and after any maintenance electrical wirings must
be controlled, electrical precautions must be taken; valve must be tested if it is working
proper with actuator.
