APPLICATION WARNING!!!
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 Ventilator (HRV), by using the
balancing procedure found in this manual.
It is always important to assess how the operation of any Heat Recovery
Ventilator may interact with vented combustion equipment.
NEVER install an Heat Recovery Ventilator in a situation where its normal
operation (including defrost function), lack of operation or partial failure may
result in the backdrafting or improper functioning of vented combustion
equipment!!
