FOR BEST RESULTS
When installing the Exhaust Fan/Light in a new construction site,
install housing during the rough-in construction of the building. The
blower unit, reflector and grille should be installed after the finished
ceiling is in place.
PLANNING DUCTWORK AND WIRING

1. Use 4" round duct.
2. Plan duct run from discharge opening of fan to the outside. For
best fan performance, make duct run as short as possible and use
minimum number of elbows.
3. Use optional NuTone ducting accessories as needed.
WIRING
Plan to run 120vAC house wiring (with ground) from power source,
through wall switch, to junction box in housing. For separate control of
fan and light use an optional NuTone switch.
