Safety Information
Warning!
-
To reduce the risk of electric shock, ensure electricity has been turned off at the circuit breaker or fuse box before beginning.
-
All wiring must be in accordance with national and local electrical codes. Electrical installation should be performed by a qualified licensed electrician.
-
This fan is suitable for use with solid-state speed controls.
-
To reduce the risk of personal injury, use only the fasteners provided with the junction box for mounting to the junction box. Most junction boxes commonly used for the support of lighting fixtures are not acceptable for fan support and may need to be replaced. Consult a qualified electrician if in doubt.
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, & PERSONAL INJURY, MOUNT FAN TO A JUNCTION BOX MARKED “ACCEPTABLE FOR FAN SUPPORT”. -
The junction box and support structure MUST be securely mounted and capable of reliably supporting a minimum of 50 pounds. Use only UL listed junction boxes marked “FOR FAN SUPPORT”.
-
After marking electrical connections, spliced conductors should be turned upward and pushed carefully up into the junction box. The wires should be spread apart with the grounded conductor and the equipment-grounding conductor on one side of the junction box.
-
The fan must be mounted with a minimum of 7 feet clearance from the trailing edge of the blades to the floor.
-
Do not use the reverse switch while the fan blades are in motion. To prevent damage and ensure long use, the fan must be turned off and the blades stopped before reversing direction.
-
Do not place objects in the path of the blades.
-
Exercise caution when working around or cleaning the fan.
-
Use a soft dry cloth to clean the fan body and blades. Do not use water or detergent.
-
The electrical diagrams provided herein are for reference only. Light kits that are not packaged with the fan must be UL listed and suitable for use with this fan. Switches must be UL general use switches. Refer to their separate instructions for proper assembly.
NEVER BEND THE BLADES FOR ANY REASON.
Preparation
-
Turn Off Your Power
Begin installation by removing fuses or turning off circuit breakers to the wiring you will be using. Use your compatible UL listed junction box if you already have one installed.
Failure to disconnect the power supply prior to installation may result in serious injury or death. -
Choose Your Mounting Position
If you need to install a new UL listed junction box, secure it directly to your building’s structure usingappropriate fasteners and materials. Do not use plastic boxes. The junction box and its supports must be able to support the MOVING weight of the fan (at least 50 lb.) and be rated for fan support. -
Choose a Suitable Location
Ensure the blades will be at least 30 inches from any obstruction and at least 7 feet above the floor. In locations without a ceiling joist, a hanger support bar may be required. Do not install in damp locations.
Initial Installation
Step 1. Pass the supply wires from the junction box through the central hole
of the mounting bracket.
Step 2. Secure the bracket to the junction box with the flat or ring washers
and mounting bolts or screws.
Downrod Mounting
Step 1. Remove the pin and clip from the downrod.
Then loosen the two locking bolts in the yoke at the top of the motor
assembly.
Step 2. Carefully place the canopy, canopy cover, and coupling cover onto the
downrod. Feed the lead wires from the fan motor through the downrod.
Step 3. Install the downrod onto the yoke, aligning the holes, inserting the
pin through the downrod, and reinstalling the clip. Then retighten the locking
bolts.
Step 4. Place the downrod’s mount onto the mounting bracket. Rotate the entire
assembly until the tab has dropped into the mount’s slot and locked firmly
into place. The motor assembly should no longer rotate if seated properly.
Failure to reattach the locking pin and/or properly seat the downrod can cause
the fan to fall from the ceiling during operation.
DO NOT use the fan before ensuring it is properly secured and the motor
cannot rotate.
Circuit Connections
Again, ensure that the power has been cut before working with the wiring. Use
the wire nuts provided with your fan.
Ensure there are no loose wires or connections, and secure connectors with
electrical tape.
Step 1. Insert the receiver into the tray with the receiver facing the
ceiling. For best results, make sure the white antenna on the end of the
receiver remains extended and not tangled with any of the electrical wires.
Step 2. Connect the 3 colored wires of the receiver to the 3 identically
colored wires of the fan motor. Secure each set with the provided wire nuts.
Step 3. Connect the 2 colored wires of the receiver to the 2 identically
colored wires of the junction box. Secure each set with the provided wire
nuts.
Step 4. Connect the green or bare copper ground wire of the junction box to
the ground wire of the ceiling fan motor. Separate the white and green
connections from the black wire connections, which should be kept on opposite
sides of the junction box.
Canopy Installation
Step 1. Tuck all the connections neatly into the junction box.
Step 2. Slide the canopy up to the ceiling mounting bracket and place the key
hole slots over the mounting screws or bolts on the bracket. Rotate the canopy
until the screw or bolt heads lock in place at the narrow section of the key
hole.
Step 3. Attach the canopy cover to the bottom of the canopy and screw it into
place.
Fan Blade Installation
Step 1. Remove the 6 blade bolts from the edges of the fan motor assembly.
Step 2. Remove the 6 locking bolts from the provided round locking plate.
Step 3. Fit a blade onto the fan motor assembly and replace 2 blade bolts.
Step 4. Attach the locking plate onto the bottom of the fan motor assembly,
aligning its holes with those on the blade.
Step 5. Replace 2 locking bolts onto the locking plate.
Step 6. Making sure the blade is straight, tighten these bolts.
Step 7. Repeat for the remaining blades.
Step 8. Mount the decorative cover onto the bottom of the fan and screw it
into place.
Remote Control Operation
Install the remote control holder onto any wall or suitable flat surface using the two steel screws.
| Key | Function |
|---|---|
| 1 | Starts the fan at the indicated speed level from low (1) to high (TURBO) |
2
3
4
5
TURBO
| Turns the fan on/off
R/F| Reverses the fan’s direction
| Runs the fan in preset mode, alternately upshifting and downshifting the
speed level
1h| Runs the fan for 1 hour and then turns it off
2h| Runs the fan for 2 hours and then turns it off
4h| Runs the fan for 4 hours and then turns it off
DO NOT press R/F while the fan is turning. Wait for it to stop completely
before changing the direction of its rotation.
This remote operates with a range of 30 feet (10 m). It uses 2 1.5V AAA
batteries (not included).
If the remote will not be used for a prolonged period, it is recommended to
remove the batteries for better service life.
Troubleshooting
| Potential Problems | Common Solutions |
|---|---|
| Fan blades don’t rotate | Check fuses and/or circuit breakers and reset if |
needed.
Cut off power to the fan and check its internal electrical connections.
Replace the remote control’s batteries.
Check that the fan cover is correctly placed and no screws interfere with the
movement of the blades.
Contact customer service to replace a faulty remote control.
Fan is too noisy| Check that all fasteners are well tightened.
Ensure the canopy housing has a short distance between itself and the ceiling.
Upon initial installation, allow 24 hours of use for the machine to break
itself in.
Cut off power to the fan and check that the wire nut connections are not
rubbing against one another or the inner housing.
If you have installed a solid-state variable-speed control, cut off power to
the fan and disconnect this control from the device. See if using the remote
resolves the problem, which can be caused by erratic signals from such
controls.
Fan wobbles during use| Check that all fasteners are well tightened.
Use the provided balance kit to adjust the blades if their tips are found to
be an unequal distance from the ceiling while well fastened.
Exchange the position of the various blades.
Again, do not bend the blades during any of these procedures.
