Installation examples
* Drawings are illustrations only and actual port locations and airflow directions may vary, consult unit spec sheets.
It is the responsibility of the installer to ensure all ductwork is sized and installed as designed to ensure the system will perform as intended.
The amount of air (CFM) that an HRV will deliver is directly related to the total external static pressure (E.S.P.) of the system. Static pressure
is a measure of resistance imposed on the blower by length of duct work/number of fittings used in duct work, duct heater etc.
Fully Dedicated System
• Stale air drawn from areas of contamination
• Fresh air supplied to main areas
• HRV airflow should be balanced
• External heating or cooling coil may be needed if air is not able to mix comfortably.
