Balancing The Airflows; Balancing The Airflows Using The Door Ports - Lifebreath AIRIA MAX Serie Guide D'installation

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 (i.e.
digital manometer) 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 illustration for port
locations). Seal the fresh air balancing ports with tape
(see illustration for port locations). Record your
reading. Note: Use upper left and lower right ports
on reverse flow models (155MAX RX).
Step 6: Insert the 2 rubber fittings from the gauge to
the fresh air balancing ports (see illustration for port
locations). Seal the stale air balancing ports with tape
(see illustration for port locations). Record your
reading. Note: Use lower left and upper right ports
on reverse flow models (155MAX RX).
Step 7: Refer to the "Airflow Reference Chart" for
your model and determine the fresh air and stale
airflow rates (page 22).
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 fresh air and stale air ports will be reversed.
