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. Refer to instructions on page 3 to install the Exhaust Fan/Light in an existing finished building.

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. (Night light not provided on 8664RP).
