Air Flow Balancing using the Door Ports
Models RNC155 and RNC200 Only
The door ports ( MODELS RNC155 & RNC 200) are designed
to quickly and measure the airflows for balancing.
to quickly and measure the airflows for balancing.
Normally the HRV would be balanced on high speed. If the
HRV is connected to a forced air system, both systems should be
set to run at the highest operational speed when balancing is
performed.

Step 1
Remove balancing port covers.
Step 2
Insert one end of each connection hose into a rubber
fitting. (Use light pressure until fitting is snug).

Step 7
Damper the airflows as required to balance the system.
The fresh airflow must equal the stale airflow.

Step 8
Repeat steps 4 to 7 as required to confirm airflows.
