the DISS demand flow valve (F) two more full turns.

5. Install the DISS nut (I) securing the transducer (E) to the DISS demand
flow valve (F).

6. Being careful not to damage the DISS fittings, securely tighten the DISS
nut (I).

7. Connect the green wire (or shield wire) (A) to the appropriate position on
the terminal block (D) inside the transducer (E).

8. Connect the red and black wires (B) to the terminal block (D).

NOTE:
Polarity does not need to be observed for the red and black wires.
