Adjusting Compressor Pressures

Notes

• NVloop gets very sensitive as it closes. It may not seem to be doing anything for a while, but may change Pinlet and Pdischarge a lot around the last 1/4 of the thread. The compressor may turn off if Pinlet drops too low.

Increasing Pdischarge and Decreasing Pinlet

1. Close NVloop.
2. Add gas by opening regulator and valve to maintain Pinlet = 1-3 psig.

Decreasinge Pdischarge and Increasing Pinlet

1. Open NVloop.
2. Remove gas by opening NVvent to maintain Pinlet = 1-3 psig.
