5. HOW TO TEST THE UNIT
After the unit has been installed, the low voltage connection has been made, and the ducts and hoods have
been installed, the airflow can be tested. To do so:
1.
Open the unit's door and take note of the unit's Run time % setting.
2.
If connected to the ducting of an AHU, turn the AHU OFF while measuring
the airflow.
3.
Turn the Run time % button in the "Test" position and close the door.
4.
Wait until the booting sequence is done (at least 45 seconds).
5.
Remove the test port cap located on the port on the intake side of the unit
(closest to the filter).
6.
Test the airflow using a Pitot tube. The distance between the test port and
the center of the duct is 3.75 inches.
7.
Put the cap back on the test port.
8.
Set the Run time % button back to its previous setting.
