How to change a Damper Actuator
Before You Begin
- Isolate the AHU at the control panel isolator and confirm the panel is de-energised.
- Obtain the correct replacement actuator and manufacturer’s data sheet.
- Access the AHU asset tag and retrieve the relevant wiring diagram.
- Ensure the replacement cable and terminations match the approved wiring arrangement.
Quick Overview
- Isolate the AHU and obtain the correct replacement actuator.
- Access the wiring diagram through the asset tag.
- Remove the faulty actuator and fit the new unit to the spindle.
- Wire, power up and confirm correct damper operation.
