Balancing the Airflow using the Door Ports
Door balancing ports are designed to be used in the conjunction with a digital manometer to measure
the stale and fresh airflows for balancing.
Step 1: Prepare the airflow measuring device by connecting the hoses to the low and high pressure
side of the gauge.
Step 2: Insert the hoses into the rubber fittings from the optional door port adapter kit (part
99-182). Use light pressure and rotate until fitting is snug. Do not extend the hose past the rubber
fitting.
Step 3: Open the HRV door. Remove the 4 door port covers by carefully pushing them out from the
back side of the door.
Step 4: Close the HRV door. Initiate power and operate the HRV on high speed. Operate the forced
air system on high speed (if the HRV is connected to the forced air system).
Step 5: Insert the 2 rubber fittings from the gauge to the stale air balancing ports (see illustrations
for port locations). Seal the fresh air balancing ports with tape
(see illustrations for port locations). Record your reading.
Step 6: Insert the 2 rubber fittings from the gauge to the fresh air balancing ports (see illustrations
for port locations). Seal the stale air balancing ports with tape
(see illustrations for port locations). Record your reading.
Step 7: Refer to the "Airflow Reference Chart" for your model and determine the fresh air and stale
airflow rates (the chart is located on page 24 and 25).
Step 8: Damper down the higher airflow and repeat Steps 5 to 7 as required until both airflows are
identical (balanced).
Step 9: Remove the tape and rubber fittings and reinstall the 4 Door Port Covers.
