Date Required: 5/4/2016
Due to drive aisle clearance issues, the SCL vault cooling fan previously located in the garage has been replaced by two down-blast type exhaust fans on the low roof (at Level 2). Please confirm that the location shown for the fans, per the markup of M105, is architecturally and structurally acceptable. Please note that the opening at each fan location will be about 30” x 30” (see attached fan submittal dimensions). In addition, based on the attached fan submittals, please confirm with SCL if the airflow to the transformer room produced by these fans is acceptable. Suggestion
