•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 fan will operate most efficiently when located where the shortest possible duct run and minimum number of elbows will be needed.

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).
