• Locate unit above (GFCI protected circuit required) or
within 5 feet of shower head.
• Locate unit away from heating or cooling sources
which can affect humidity levels.
• Do not locate near window. Unit may respond to the
outdoor humidity level.
• Unit must be installed in ceiling to properly sense
moisture.
• Locate unit only on flat ceilings up to 12 feet high for
proper sensing.
• 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 rout-
ing possible for best performance, and avoid installing
the fan with smaller ducts than recommended. Insula-
tion around the ducts can reduce energy loss and
inhibit mold growth. Fans installed with existing ducts
may not achieve their rated airflow.
2. Plan the wiring.
• Plan to supply the unit with proper line voltage and
appropriate power cable. Power cable should be
routed to the switch box first and then to the unit
(See "CONNECT WIRING" on page 3).
• Do not operate this unit with a speed control.
Damage to the sensor unit will result.
