Hi,
I am conducting PQ for HVAC system in the next month. I intend to devide the qualification period into 2 phases: first week for “at rest” condition, and then about 4 weeks for “in operation”. I notice that there are two ways to conduct the PQ of HVAC system. The first one is qualify each AHU seperately and the second one is qualify each criterion seperately. I wonder if the first one is acceptable.
To be clear, my facility is designed to be complied with D class GMP.
Thank you.
