Balancing the Airflow using the Door Ports

Door balancing ports ( not on all models ) 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
rates (the chart is located on page 23).
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.
Attention
Reverse Flow Models: Step 5 and Step 6 stale air and stale air ports will be reversed.
