Section 6: Electrical Connection• Move valve to mid-position by override nut. This will allow sufficient time to stop

actuator in case of improper hook-up.

• Identify means of removing power during hook-up.

• Be sure no erroneous remote control signals can be received causing actuator to energize.

• Electrically operate the valve in the open direction. If the valve closes, actuator must be stopped and checked for improper field wiring.

• Set all field conduit entries in accordance with National Electric Code Requirements.

Section 10: Maintenance and Storage

At least once a year a check should be made of your EIM HQ Series Actuator.

• Disconnect all power to actuator.

• Open electrical enclosure. Inspect and tighten all electrical connections.

• Visually inspect for any electrical or mechanical damage. Replace worn or damaged components.

• Check lubrication consistency and levels. Fill or replace if required.

Actuators must be stored in a clean, cool and dry area. The unit shall be stored with the cover installed and the conduit openings sealed. Storage must be off the floor, covered with a sealed dust protector.
