1. Locate where the pressure tap is going to be installed. The pressure tap should be 5 duct diameters
from the applicable opening of the unit or midpoint between applicable opening and rst down-stream
obstruction (bends, splits, dampers, coils, diusers, etc). Use the mounting location that allows for the
furthest distance from the unit, drill a 5/16” hole and install pressure tap.
To unit
*** If there is another AHU (i.e. DOAS, furnace, etc) in series downstream of the unit then the pressure
tap should be located downstream of the AHU as described above.
