ALL INSTALLATIONS

IMPORTANT - The ducting from this fan to the outside of the
building has a strong effect on the air flow, noise and energy use
of the fan. Use the shortest, straightest duct routing possible for
best performance, and avoid installing the fan with smaller ducts
than recommended. Insulation around the ducts can reduce
energy loss and inhibit mold growth. Fans installed with existing
ducts may not achieve their rated airflow.
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer.
