2.9 optional 5-Valve assembly Procedure
the 5-Valve manifold assembly is normally shipped with valves V1, V2, V4, and V5 closed,
and V3 open.
To Place into service (Unit is mounted vertically):
1. Confirm valves V1, V2, V4, and V5 are closed and V3 is open.
2. Mount the manifold and install process connections to V1 and V2.
3. High Pressure Side: Slowly open V4 to bleed the air out of the high pressure side, close V4 when air stops
bleeding. Open the 2 bleed screws on the high pressure side of the Model 230, see Sec. 2.7, paragraph 1.
4. Install the pressure gauge on V4. Open V4.
5. Low Pressure Side: Slowly open V5 to bleed the air out of the low pressure side, close V5 when air stops
bleeding out. Open the bleed screw on the low pressure side of the Model 230 transducer, see Sec. 2.7, para-
graph 1.
6. Install the pressure gauge on V5. Open V5.
7. System is bled, close V3 to apply differential pressure to the Model 230.
To take out of service:
1. Open V3 to equalize the pressure.
2. Close the V1 and V2 valves to disconnect pressure supply.
3. Slowly open the low and high pressure bleed ports to depressurize the system.
