2. Replace with the fresh air supply duct (with the flange nearest the false ceiling when the unit is installed) and
secure using the four screws provided.
3. The installer must provide ductwork, a screened source of fresh air and an auxiliary fan.
4. An an auxiliary fan must be sized to overcome the resistance of the filter, the ductwork and the IMAGE 875 unit

any given unit and fan speed)
