Start Up Procedure; Airflow Balancing - Fantech SHR 1504 Installation Manual

Installing drain line
Through normal operation and during its defrost mode, the HRV may produce some condensation. This water should flow into a nearby drain, or be taken
away by a condensate pump. The HRV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point.
A "P" trap should be made in the drain line. This will prevent odors from being drawn back up into the unit.
1 Install the drain nipple.
Secure the condensate line to the drain connection using a tie wrap or other appropriate method.

Start up procedure

The Switch on the side of the unit is used to toggle between STANDBY, REDUCED speed and NORMAL speed modes.
Place the unit in NORMAL speed to perform the balancing.

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.
