plastic

• Maximum ambient operating

temperature of 104°F/40°C

The Vari-Cyclone DC Powered Ceiling Fan is the perfect choice for a variety of

indoor/outdoor applications, including workplaces, warehouses, businesses and many

rooms in the home. The Vari-Cyclone’s 60" diameter blades, designed by the Florida

Solar nergy Center in cooperation with a major fan manufacturer, utilize “Gossamer

Wind Technology” found only in AC powered fans until now. We are the only DC fan

company allowed to use these revolutionary new fan blades. The “Gossamer Wind

Technology” blades allow the fan to produce up to 40% more air flow with no increase in

power consumption, making the Vari-Cyclone the most energy efficient DC powered

ceiling fan available.

The Vari-Cyclone is powered by a permanent magnet, T NV (totally enclosed non-

ventilated) motor with long life brushes. The Vari-Cyclone draws 0.5 amps @ 12 VDC

and 0.78 amps at 24 VDC. At 12 VDC the 3-blade fan will have approximately 102 rpm

moving 1,476 CFM when mounted at least 8 feet above the floor in an open room. At 24

VDC the 3-blade fan will have approximately 138 rpm moving 3,925 CFM when

mounted at least 8 feet above the floor in an open room.

For maximum efficiency use the Nextek Power Systems Speed Control in conjunction

with the Vari-Fan DC Powered Ceiling Fans. The Speed Control makes clockwise and

counter-clockwise rotation possible.

5.0 NOTES AND WA NINGS

5.1 NOTES:

5.1.1 It is recommended that all Nextek Fanworks DC ceiling fans be used in

conjunction with the Nextek 12/24V Speed Controller.

5.1.2 If operating in a 12V environment, the 12/24V speed control is required.

5.1.3 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.

5.1.4 A Nextek 12.6 watt solar panel is available and perfectly matched for this

DC powered ceiling fan and speed control.

5.1.5 For new installations: This is a low-voltage 12/24V DC-powered device.

Appropriate sizing of a solar panel, battery and battery charge controller

are essential for proper operation. Consult a qualified installer of DC

devices to insure correct configuration.

5.1.6 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.

5.1.7 Failure to wire correctly or install in a non-recommended power

environment may violate your warranty.

5.2 WA NINGS:

5.2.1 To reduce the risk of fire or electrical shock use Nextek 12/24V speed

controls only.

5.2.2 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.

5.2.3 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.

5.3 CAUTIONS:

5.3.1 Read entire instructions carefully before beginning installation.

5.3.2 To avoid possible electrical shock, be certain electricity is shut off at main

panel before wiring.

5.3.3 All wiring must be in accordance with national and local electrical codes.

If you are unfamiliar with wiring, you should use a qualified electrician.

7.0 INSTALLATION P OCEDU E

7.1 Pre-Installation Instructions

7.1.1 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 7.3 below.

7.1.2 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.

7.1.3 The fan blades must be mounted

at least 7' above the floor. For

maximum efficiency, they should

not have any obstruction (walls,

posts, etc.) within 24" of the blade

tips. See Figure 1 for mounting

distances.

7.2 Inspection of Fan

7.2.1 Unpack the fan carefully to avoid any damage to the components.

7.2.2 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.

7.2.3 Check contents to be certain it contains a bag of parts.

7.3 Installation of Outlet Box and ough-In Wiring

CAUTIONS:

Your ceiling fan, when operating, can have a weight plus downdraft of 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 total weight of 35 lbs.
