IMPORTANT - PLEASE READ THIS MANUAL
BEFORE INSTALLING UNIT
CAUTION - Before installation, careful consideration must be given to how this system
will operate if connected to any other piece of mechanical equipment, i.e. a forced air furnace
or air handler, operating at a higher static. After installation, the compatibility of the two piec-
es of equipment must be confirmed by measuring the airflow’s of the Heat Recovery
Ventilators by using the balancing procedure found in this manual.
It is always important to assess how the operation of any HRV may interact with vented com-
bustion equipment (i.e. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.).
NEVER - install a ventilator in a situation where its normal operation, lack of operation or par-
tial failure may result in the backdrafting or improper functioning of vented combustion equipment!!!
