Safety Warnings

Ensure electrical power is turned off at the circuit breaker before beginning installation.
Verify that the junction box is specifically listed for ceiling fan use to prevent the unit from falling due to torsion and weight.
Ensure fan blades are installed at least seven feet above the floor to prevent injury.
Do not position the fan blades directly underneath existing light fixtures to avoid strobing effects.

Screwdriver — Phillips #2

Wrench — 1/2-inch

Measuring Tape — Standard

Fan-Rated Junction Box — UL Listed for fan support(1)

Ceiling Fan Kit — Residential (Damp-rated for bathrooms/porches)(1)

Turn off power to the circuit and verify the existing ceiling junction box is a fan-rated box supported by a structural ceiling joist.

Tip: Standard light fixture boxes are often insufficient for the weight and torsion of a moving fan.

Measure the ceiling height to ensure the fan blades will be positioned at least seven feet above the floor.

Tip: Industrial fans require a higher clearance of 10 feet.

Install the fan-rated junction box and mounting bracket to the ceiling joist if the existing hardware is not rated for fans.

Tip: The weight must be carried by a strong structural element of the ceiling.

Assemble the fan motor and downrod according to the manufacturer's instructions and lift the motor assembly into the mounting bracket.

Tip: Ensure the horizontal separation from any nearby light fixtures is maximized to prevent strobing.

Connect the electrical wiring from the ceiling to the fan motor, ensuring all connections are secure.

Tip: Refer to your local electrical code for grounding requirements.

Attach the fan blades to the motor shell using the provided screws.

Tip: Ensure all screws are tightened straight; unevenly tightened blades can cause the fan to wobble.

Install the decorative canopy and light kit (if applicable) to cover the wiring and mounting bracket.

Tip: If installing in a bathroom or porch, ensure the unit is UL Damp-rated.

Restore power at the circuit breaker and test the fan at various speeds.

Tip: If the fan wobbles, check for warped blades or bent blade irons.

To avoid a 'strobing' effect, do not place light fixtures directly above the fan blades.
Wobbling is typically caused by weight imbalance, warped blades, or blade irons not being screwed on straight.
For moisture-prone areas like bathrooms or covered patios, always use UL Damp-rated fans; for direct rain exposure, use UL Wet-rated fans.
