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.

IMPORTANT: Use wire suitable for 90°C.

Plan to run 120vAC house wiring (with ground) from power source,
through wall switches, to junction box in fan. For separate control of
fan, light, and night light three wall switches are required. See
NuTone Catalog for accessory switches. For separate control of fan,
light, and night light, five conductors are needed between the wall
switch box and the fan's junction box.
