CAUTIONS

1. Before wiring the paddle fan, turn off the electric power supply
at the main fuse or circuit breaker box and leave
it off until the installation is complete.

2. Mount the outlet box so it will support a minimum of
45 pounds. The outlet box must be mounted flush to ceiling.
Do not use a plastic outlet box.

3. Do not install paddle fan with less than 7 feet clearance
between floor and lowest edge of fan blades.

4. If you are unfamiliar with electric wiring, acquire
the services of a qualified electrician.

5. Use proper cable and fittings. Be certain the fan is properly
grounded. Wiring must comply with national and local
electrical codes.

6. Electrical requirements: 120vAC, 60 Hz, single phase,
1 amp. – without optional lighting accessory.

7. Fan blades may be cleaned with a mild soap solution. Do not
use an abrasive cleaner or a strong chemical cleaner.

8. WARNING: To reduce the risk of fire or electrical shock,

do not use this fan with any solid-state speed control
device (NOTE: Refer to NuTone's catalog for appropriate

speed control switches.)

9. WARNING: To reduce the risk of personal injury,

do not bend the blade brackets when installing the
brackets, balancing the blades or cleaning the fan. Do not
insert foreign objects between rotating fan blades.

10. CAUTION: To reduce the risk of electric shock, connect only

interrupter.

11. CAUTION: To reduce the risk of electric shock, fire or

personal injury, a light kit must be marked suitable for use
with this fan and must be marked as suitable for outdoor use.

12. Do not operate reversing switch while fan blades are in

motion. Fan should be turned off and blades stopped before
reversing blade direction.

LOCATION

1. Minimum ceiling height: 8 feet. When fan is installed,
this allows a minimum of 7 feet between the floor and fan
blades.

2. The center of the fan must be located at least 32" from
any vertical surface.

3. Do not mount fan below, next to or between air ducts, beams
or any other obstruction which may interfere with the natural
air flow pattern created by the fan.

4. Fan can be mounted using down rod or closer to ceiling using
ceiling cup as close up adapter.

ceiling where the maximum angle of the sloped ceiling does
not exceed 25°.

2. For any angled ceiling, use appropriate NuTone Extension
Stems to insure proper clearance between the blades and
ceiling. See NuTone catalog.

MOUNTING OUTLET BOX

Refer to Figure 2.

CAUTION: To reduce the risk of personal injury, install the
supplemental mounting means and use only the hardware
provided with the fan or use a listed outlet box marked as
acceptable for fan support. If the combined weight of the
ceiling fan and any light kit used with it exceeds 35 pounds,
the fan should be supported independently of the outlet
box. The weight of your fan is 20 lbs.

1. Fan mounts to a standard 4" metallic outlet box or a listed fan

support box. For damp location mounting, use outlet box listed
for “Damp Locations”. For outdoor mounting use outlet box
listed for wet locations.

MODEL: PFOB-52

2. When using a standard outlet box install a header between
joists and securely mount outlet box to header. Using two
screws supplied with the outlet box attach socket hanger
securely to outlet box. Place rubber pads between hanger
and box. Using 3" screws (supplied) install screws through
the socket hanger mounting slots, outside of the outlet
box, through the ceiling and into the header. Do not
overtighten or socket hanger may be damaged. These
screws serve as supplemental support independent of
the outlet box.

When using a listed outlet box marked acceptable for

fan support, follow instructions provided with the box.

MOUNTING THE FAN WITH DOWN ROD

1. Refer to Figure 6. To install the ball and stem assembly
to the fan, feed the wires from the fan through the rubber
canopy, the ceiling canopy and down rod.

2. Insert stem of rod into flange on the top of fan. (It may
be necessary to back out the set screw in flange).
Line up holes in stem and flange and insert smooth pin
through flange and stem. Secure pin with hitch pin. Tighten
set screw in flange.

3. Refer to Figure 6. Run wires from fan through
rubber cover. Lift fan and place ball hanger into socket
of socket hanger. Rotate fan until groove in ball locks
with tab in socket.

MOUNTING FAN WITH
CLOSE UP ADAPTER

1. Remove soft plastic bushing from the center of the ceiling
cup. Secure ceiling cup to top of fan using three screws
and lockwashers provided in the hardware bag. ( The
down rod and ball are not required for this installation.)

2. Hang the fan from the tab on the back of the hanger
bracket using one of the holes in the ceiling cup. This will
support the fan while wiring connections are made.

WIRING CONNECTIONS

Refer to Figure 4.

All wiring must comply with national and local codes.

Be certain the power is disconnected before proceeding.

1. Connect fan wires to house supply wires using listed wire
connectors. Make connections as follows: Black to black,
white to white and green ground wire to green or bare
copper ground from house supply.

IMPORTANT: For wall switch control use only listed

general use switches.

2. After splices are made turn them upwards and carefully
push into outlet box with white and green wires on one
side of outlet box and black wires on the other side.

3. Using four screws (supplied) secure ceiling cup to socket
hanger.
