Per Robert Schofield, Fans 1 & 2 supplying the LVEA were readjusted to lesser airflows for the Observation Run. The total CFM for AHU 1 was reduced from ~ 26,000 to ~ 11,200 CFM. AHU 2 will require some mechanical adjustment to the linkage in order to achieve the much lower CFM. This will be done at the next opportunity when we are no longer locked or on maintenance tuesday.
