Section 1: General
HQ series electric actuators are design to provide reliable and efcient operation of 90°
quarter-turn valves, dampers, etc.
WARNING
!
Use caution when working in, with, or around valves and actuators. High pressures, forces,
voltages and ammable media can be present. Failure to follow instructions for proper
electrical wiring, storage, set-up and maintenance may cause serious injury, damage
equipment, or void warranty.

Section 6: Electrical Connection
• Move valve to mid-position by override nut. This will allow sufcient 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 eld wiring.
• Set all eld 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
