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.
