GETTING
STARTED
The Fresh Air Ventilation System is designed to
supply fresh air and exhaust stale air. The system
draws fresh outdoor air through the ventilator for
distribution throughout the house.
Heat Recovery Ventilator
Stale air is exhausted through the ventilator and to
the outdoors. Heat is transferred from one airstream
to the other as the air passes through the opposite
sides of the heat transfer core. See Fig. 1.
Energy Recovery Ventilator
Stale air is exhausted through the ventilator and to
the outdoors. Heat and moisture is transferred from
one airstream to the other as the air passes through
the opposite sides of the energy transfer core.
See Fig. 2 and 3.

Failure to comply with these requirements will result in voided warranty, improper installation, and
