These schematics illustrate temporary deployment locations for probes during the commissioning process; these probes connect to smartphone commissioning applications.
Image
A duct leakage test is performed on a ducted heat pump system using a duct tester (blower fan) and a digital manometer.
Image
A flow grid is inserted into the filter grille/slot to directly measure airflow.
Image
A static pressure measurement is taken on this air handler using probes on the supply and return sides of the fan.
Image
A vacuum decay test is performed on this ductless mini-split heat pump using a digital micron gauge for accurate measurement; a deep vacuum is achieved quickly by using large diameter, vacuum-rated hoses, and removing valve cores
