PLANNING THE INSTALLATION
Application
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.
Stale air is exhausted through the ventilator 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.
