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, ERV unit should be re-balanced after a major renovation or after the  

 

 

 

 

installation of extra grilles or registers.

 

 

 

 Remove the nutsert. 

INSTALLING DRAIN LINE

Through normal operation and during its defrost mode, the ERV may produce some condensation. This water should flow into a nearby drain, or be taken 
away by a condensate pump. The ERV 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.

2  

Invert the drain nipple. Make 

sure to place gasket between 
the unit and the drain nipple 
inside the unit.

3  

Secure the drain nipple using 

the nutsert.

4  

Install the drain hose making a 

"P" trap, secure the 
condensate line drain 
connection using the tube 
clamp provided.

  Fill the condensate line with 

water.

The drain nipple is placed upside down in the unit to prevent it being damaged during shipping or the installation of the unit.
