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.

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.

Balancing Procedure

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 3 Attach the connection hoses to pressure gauge

Step 4 Fresh Air - Connect hoses to door ports as illustrated (record reading).

Step 5 Stale Air - Connect hoses to door ports as illustrated (record reading).

Step 6 Refer to the Airflow Reference Chart for the conversion of gauge reading to airflow reading.

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.
