Removing the differential pressure sensor

1.Label the pressure sensor tube connection locations, and then remove the tubes from the differential pressure sensor.

2.Label the sensor wire connection locations, loosen the screws securing the sensor wires, and then remove the sensor wires.

3.Remove the two nuts (1) and two bolts (2) securing the differential pressure sensor, and then remove the differential pressure sensor.

Replacing the differential pressure sensor

1.Replace the differential pressure sensor, and then secure the differential pressure sensor with two bolts

(1) and two nuts (2).

2.Insert the pressure sensor tubes into the differential pressure sensor according to the connection locations you labeled during the removal procedure.

3.Replace the sensor wires according to the connection locations you labeled during the removal procedure, and then secure the sensor wires by tightening the screws.
