Lifebreath Accu-Flow is designed to quickly and accurately balance the
airflows on units equipped
with balancing ports. Normally the HRV/ERV would be balanced on
high speed. If the HRV/ERV is connected to a forced air system, both
systems should be set to run at the highest operational speed when
balancing is performed.
Procedure:
Step 1 Remove balancing port covers.
Step 2 Insert rubber fittings into balancing ports on door. (Use light pressure until fitting is snug).
Step 3 Attach tubes to balancing gauge.
Step 4 Place gauge on metal door (gauge is equipped with a magnetic strip). Ensure gauge is level/plumb.
Step 5 Connect tubes to door ports as illustrated in step 5 (record readings).
Step 6 Connect tubes to door ports as illustrated in Step 6. (record readings).
Note: It is normal practice to lightly tap gauge if reading is non-responsive.
Step 7
Damper airflows as required.
Step 8
Repeat Steps 5 and 6 as required to confirm airflows
Step 5
Measuring Fresh Air Side (Always connect left side port
first).
