WARRANTY:
All fan bodies and fan motors are
warranted against defect for one (1) year
from time of sale. Please keep any dated
invoices or sales receipts for proof of
purchase.
DISCLAIMER:
All DC powered ceiling fan motors are
rated for one (1) amp maximum input.
All warranties on the motor and body
part are voided if the power input to the
motor exceeds one (1) amp.
When operating an DC powered ceiling
fan directly from a Photo Voltaic (PV)
panel, without a battery in the circuit, be
sure the output of the panel does not
exceed 20 watts at 12 or 24 Vdc.
THIS WILL VOID YOUR WARRANTY.

IMPORTANT INFORMATION :
1. It is recommended that all Nextek
Fanworks DC ceiling fans be used in
conjunction with the Nextek 12/24V
Speed Controller.
2. If operating in a 12V environment, the
12/24V speed control is required.
3. The Nextek DC ceiling fans can be
operated above 24VDC, but not to
exceed 48VDC. A 48VDC Speed
Controller can be special ordered. The
12/24V speed control is designed to work
only between 12V and 24V.
4. A Nextek 12.6 watt solar panel is
available and perfectly matched for
this DC powered ceiling fan and speed
control.
5. For new installations: This is a low-
voltage 12/24V DC-powered device.
Appropriate sizing of a solar panel,
CAUTION:
1. Read entire instructions carefully before
beginning installation.
2. To avoid possible electrical shock, be certain
electricity is shut off at main panel before
wiring.
3. All wiring must be in accordance with
national and local electrical codes. If you
are unfamiliar with wiring, you should use a
qualified electrician.
WARNING:
1. To reduce the risk of fire or electrical shock
use Nextek 12/24V speed controls only.
2. To reduce the risk of personal injury, do not
bend the blade brackets when installing the
brackets or cleaning the fan. Do not insert
foreign objects in between rotating fan
blades.
3. To reduce the risk of personal injury, install
the fan only to the building structure
according to these instructions, and use only
the hardware supplied.

MY FAN MAKES A RUBBING SOUND WHEN RUNNING:
Turn your fan off, when the blades have stopped turning, spin the fan with your hand, if you hear the
rubbing sound, it is most likely that the fan’s hub is rubbing against the motor housing.
Loosen the hub’s set screw; remove the decorative knob covering the fan’s motor shaft. Using a flat
bladed screw driver, pry the safety push nut away from the hub (about 1/8 inch) Try spinning the fan
again, if the rubbing sound is gone, then re-tighten the set screw and replace the decorative knob.
MY FANS BLADES SEEM TO GO UP AND DOWN AS THE FAN SPINS:
Turn fan off, gently rotate hub by hand, look for the high and low movement of the blades. Grab the
hub at the high spot with one hand, with your other hand, grab the low spot, then “gently” push the
low side of the hub up while pulling down on the high side. Spin the hub again and see if the up/down
wobble is gone, if not, repeat the procedure until problem is fixed.
battery and battery charge controller are
essential for proper operation. Consult a
qualified installer of DC devices to insure
correct configuration.
6. For installation in existing DC power
environment: Great care must be taken
to ensure fan is wired properly in existing
DC power environment. Warranty may
be violated if attempting to operate in
anything other than 12/24V DC. Please
consult a qualified technician.
7. Failure to wire correctly or install in non-
recommended power environment may
violate your warranty.

TROUBLE SHOOTING:
The following are tips that may help fix a problem that you are having with a Nextek Power Systems
Fanworks DC powered ceiling fan.
FAN DOESN’T RUN:
Check all connections to make sure you have power, use a volt meter or multi tester to confirm
that the voltage is correct. If fan still doesn’t run, try connecting the fans leads directly to the
battery (no switches or speed controls) If fan still won’t run, please contact Nextek Power Systems
Fanworks, not your dealer.
FAN MOTOR IS HOT TO THE TOUCH:
Turn off fan immediately, and contact Nextek Power Systems Fanworks.
FAN MAKES “CLICKING” NOISE:
The “clicking” noise is usually a bur on one or both brushes. First try reversing the fan (i.e.: make it
run backwards) this can be done by reversing the polarity of the fans wires at the battery. If your fan
has a speed control but no reversing switch, reverse the leads that run from the speed control to
the fan. In either case, let the fan run at least 24 hours in reverse, then try running the fan in forward
and see if the noise is gone.
The second option, if your fan is not too high up, is to take a broom handle and give a sharp upward
rap to the decorative nut at the center of the fan hub. (Do this while the fan is running)
Please note: Fans in summer cottages or in places where the fan is not run for long periods of time
are more prone to developing a bur on the brushes. Before starting fan, gently spin the blades by
hand, and then turn on fan.
If problem persists, please contact Nextek Power Systems Fanworks.
MY FAN WOBBLES WHEN RUNNING:
Most fans mounted with a down rod will have a slight wobble (less than 1 inch from the center)
depending on how long the down rod is.
All Nextek Power Systems Fanworks fans come from the factory with balanced blades and blade
arms.
Make sure that the when the hub was placed on the fan shaft, that the flat on the shaft matched the
flat on the hub’s center hole.
Check that all the blade arms have the same pitch. (Lay them in line on a flat surface and check
that all the blade arms lay at the same angle.) If the pitch on one of the blade arms is different, try
twisting the arm until it matches the rest of the arms.
Most large hardware stores, Home Depot, Lowes, Ace, etc, that sell ceiling fans, have blade balancing
kits. These are very inexpensive and have good instructions, if the above ideas don’t work, pick up a
kit and try it.
Step 2: Inspection of Fan
1. Unpack the fan carefully to avoid any
damage to the components.
2. Check for any shipping damage to the
motor and the fan blades. If more than
one fan is being installed, keep the
matched and balanced fan blades in sets,
as they were shipped. Should one of
the fan blades become damaged during
shipment, return all blades in the set for
replacement.
3. Check contents to be certain it contains
a bag of parts.

Figure 1

Step 3: Installation of Outlet Box and
Rough-In Wiring
CAUTION:
Your ceiling fan with accessories can weigh
up to 35 lbs. The following precautions must
be taken for safety and to ensure that your
fan is securely mounted to the ceiling.
• Be certain electricity is “off ” at fuse panel
when inspecting or repairing installation
site.
• All wiring must meet local and national
electrical codes.
• Do not mount directly to an unsupported
ceiling or to an electrical outlet box.
Mounting must support a 35 lb. fan with
accessories.
1. Secure metallic outlet box 4” x 1-1/2”
or 4” x 1/2” deep to 2 x 4 cross brace
between two ceiling joists as shown
in Figure 2. The outlet box must be
recessed into the ceiling by 1/16”
minimum. Secure the outlet box to the
cross brace by drilling (2) pilot holes no
larger than the minor diameter of the
wood screws (5/64”) and use two #8 x
1-1/2” wood screws and washers. Use
the innermost holes for securing the
box. Orient the box so the outermost
holes will be used in Step 4B.
CAUTION:
Do not use a lubricant on screws.
Figure 2
Step 1: Pre-Installation Instructions
1. Select installation site. Check to see
that in normal use no object can come
in contact with the rotating fan blades.
The mounting site should also meet the
precautions listed in Step 3 below.
2 Installation hardware is included for a
standard drywall or plaster ceiling. You
will need a 4” x 1-1/2” or a 4” x 1/2”
outlet box and wire nuts (2) which can
be purchased from any hardware store
or electrical supply house.
3. The fan blades must be mounted
at least 7’ above the floor. For
maximumefficiency, they should not have
any obstruction (walls, posts, etc.) within
24” of the blade tips. See Figure 1 for
mounting distances.
