Remote-Mount Transducer and Demand Flow Valve Assembly
Chapter 4: Removal, Replacement, and Adjustment Procedures
Replacement
WARNING:
The demand flow valves all fit into ¼" tee ports. Ensure that the transduc-
er and demand flow valve assembly you install is for the type of gas or
vacuum in the line you are currently connecting. If the incorrect transduc-
er is installed, patient welfare may be compromised.
1. Ensure that the new gas-specific transducer (B) and demand flow valve (C)
are for the type of gas that you are currently connecting.
2. Wrap Teflon® tape two times around the pipe threads of the demand flow
valve (C) threads to seal against leaks.
3. Thread the demand flow valve (C) into the tee port (D).
CAUTION:
Do not overtighten the demand flow valve fittings. Equipment damage or
inadequate flow could occur.
4. Using an adjustable wrench, tighten the demand flow valve (C) until you feel
resistance.
5. For additional strain relief, wrap the cable around one of the screw posts (K)
before making the electrical connections.
6. Connect the green wire (or shield wire) (G) to the terminal block (J).
7. Connect the red and black wires (I) to the terminal block (J).
NOTE:
Polarity does not need to be observed for the red and black wires.
8. Tighten the electrical connections.
9. Replace and secure the lid (F) with the screws (E).
10. Connect the transducer (B) to the demand flow valve (C).
11. Being careful not to damage the DISS fittings, securely tighten the demand
flow valve (C).
12. Check for leaks in the gas connections.
13. If there are leaks, repeat step 2 through step 11.
14. To ensure proper operation, perform the “Function Checks” on page 2–5.
