Section 1: General
HQ series electric actuators are design to provide reliable and efcient 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 sufcient 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
cover installed and the conduit openings sealed. Storage must be off the oor, covered
with a sealed dust protector.
