10. Close high side equalizer valve MEH.
11. Open low side manifold valve ML and ensure high side manifold valve MEH is open.
12. The system is now operational.
Steam service (filling the water legs)
1. Ensure the steam line is depressurized with no steam.
2. Check the transmitter for a dry zero of 4 mA with no water loss.
3. Attach hose connection valve to high side vent DVH. See Figure 3-3.
4. Attach a water supply to the hose connection. The water supply should have a
maximum psi of 100.
5. Open the high and low manifold valves MH and ML and equalizer valve ME (MEH and
MEL for 5-Valve Manifolds).
6. Ensure low side vent DVL is closed.
7. Open the hose connect valve for a minimum of 30 seconds.Water will flow through
both the high and low chambers and into the pipe.
8. Close the high side manifold valve MH for 30 seconds to force water to the ML side.
9. Re-open the MH valve.
10. Open low side vent DVL until no air is observed.
11. Close the low-side vent DVL.
12. Close the hose connect valve and remove hose.
13. Close both manifold high side valve MH and manifold low side valve ML.
14. Check the transmitter zero by noting the output. If the signal reads outside of the range
3.98 mA to 4.02 mA, air is probably still in the system; repeat this procedure from step
2, and trim sensor if necessary.
15. Open the manifold high side valve MH.
16. Close equalizer valve ME (for 5-Valve Manifolds first close valve MEL, then close valve
MEH).
17. Open the manifold low side valve ML. The system is now operational.
