Installation Guidelines

1. Verify that the Honeywell MP913C1066-1 model number matches your system engineering requirements.
2. Ensure all pneumatic supply lines are depressurized and locked out before beginning mechanical work.
3. Inspect the damper shaft for scoring, corrosion, or debris to ensure proper engagement with the actuator collar.
4. Mount the actuator securely onto the damper shaft and tighten all linkage fasteners to the recommended torque specifications.
5. Connect the pneumatic control lines to the appropriate actuator ports, checking for secure fittings and zero leaks.
6. Restore pneumatic pressure, command the actuator through its full stroke, and verify smooth damper travel without binding.

Commissioning Recommendations

• Perform a complete stroke test using the pneumatic controller to verify that the damper opens and closes to the exact programmed limits.
• Check all pneumatic connections with a leak-detection solution to confirm system integrity under operating pressure.
• Monitor actuator response times during initial operation to ensure stable control loop performance without hunting or oscillation.
