ASHRAE’s “ Good Engineering Practices”.
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
pieces of equipment must be confirmed by measuring the airflow’s of the Heat Recovery or
Energy Recovery Ventilators by using the balancing procedure found in this manual.
It is always important to assess how the operation of any HRV/ERV may interact with vented
combustion 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
partial failure may result in the backdrafting or improper functioning of vented combustion
equipment!!!
