• Apply power to the unit. Move the selector switch to the CONT position to verify that the unit turns on in
continuous speed.
• Initiate a ventilation call from each of the external controls. Verify that the ERV/HRV unit turns on in high speed.
• Return the selector switch to the desired position and the external controls to the desired settings.
• Inspect the ducting to ensure that there are no kinks and correct as necessary.
Airfl ow Measurements - VNT5070 only
The VNT5070 ventilators are balanced by utilizing pressure ports located on the duct collars and a pressure-
airfl ow correlation table provided as a decal on the side of the unit.
NOTE: The VNT5150, VNT5200, VNT6150 & VNT6200 ventilators are not provided with pressure ports or
correlation charts. Instead, they are balanced by using air flow grids or pitot tubes which measure airflow
directly in each airstream.
