Caution
Before installation, careful consideration must be
given
to

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 airflows of the
Heat Recovery Ventilator (HRV) by using the
balancing procedure found in this manual.

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!
Application
Heat Recovery Ventilators (HRV) are designed to provide
fresh air while exhausting an equal amount of stale air.
General
The HRV is equipped with an aluminum core. The
device uses the stale air that is being exhausted to
condition the fresh air as it is being brought in.
These instructions are intended as a general guide and
do not supersede local codes in any way. Consult
authorities who have jurisdiction before installation.
Do not apply electrical power to the unit
until installation has been fully completed
(including low voltage control wiring).
