The transition from the piston driven (non-dried) instrument air compressor to the new (inline dried) scroll style compressor was finalized last week. The compressor is presently left at its factory set pressure of 120psi. TJ raised the high limit threshold for alarms to coincide with this change in pressure. The new system has been delivering the facility with air without issue since last week.

Amidst this transition, I elected to pressurize the compressed air line between the chiller yard and mechanical room and remove any feed/demands from it as noted in my previous alog. There were no significant pressure losses over an 8-hour period and as such I have no reason to believe that the line feeding the mechanical room is in any way compromised.
