Airflow balancing

IF THE UNIT'S AIR FLOwS ARE NOT PROPERLy BALANCED...
• THE UNIT'S EFFICIENCY MAY BE REDUCED.
• THE UNIT'S CORE MAY BECOME DAMAGED.
• NORMAL OPERATION OF THE UNIT COULD CAUSE THE PRESSURIZATION OR DEPRESSURIZATION OF
YOUR HOME, WHICH CAN LEAD TO AIR LEAKS OR BACKDRAFTING OF ANY COMBUSTION APPLIANCES.
The balancing procedure consists of measuring the supply air flow and the return air flow to ensure that they are equal. A difference of up to 10% is
considered acceptable. In the cases where the air flow is not exactly the same, it is recommended to have a higher return air flow to ensure that the
temperature of the supply air flow coming from outside is as close to room temperature as possible.
• For optimal performance, HRV unit should be re-balanced after a major renovation or after the
installation of extra grilles or registers.
