1-9 Final Installation of Actuator
1. Check the drift by extending and retracting the actuator, electrically.
2. Make small adjustments in the limit switch setting by following the steps outlined above in
Section 1-8.
3. Now you can install the actuator in your application.
4. Place the air vents (36) in the correct orientation based on the application and mounting
position of the actuator. In a vertical application, the vents may be placed in any of the
available holes. If the Linear Actuator is mounted horizontally, install the vent on one of the
sides, i.e.: not the lowest position. Place the vent on a side that is most accessible for
servicing.
