The pressure changes are expected to be in the 5-10 psi range. At the end of the aforementioned rebalancing, there may be a slight increase in the pressure of the Nitrogen going to the hall. The said increase may be around 5 psi, maybe less, maybe a psi or two more.<br>><br>> If you have any equipment that will be effected by the previously mentioned pressure changes during the rebalancing of the regulators or by the small increase in line pressure, please be prepared to make adjustments as needed. Hence the reason for rebalancing while the hall is accessible.<br>><br>> Your cooperation, as you are, is appreciated.<br>><br>> Cordially,<br>> Morgan Cook<br><br>-- <br>Marc McMullen<br>Detector Support Group<br>757-269-7738<br><br>_______________________________________________<br>Dsg-rich mailing list<br>Dsg-rich@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/dsg-rich<br></blockquote></div></div></body></html>
