• For use with dimmable LED, CFL, incandescent, and halogen bulbs only.
• Maximum load: 150 watts for dimmable LED/CFL lamps or 600 watts for incandescent bulbs. Minimum load for LED lights: 3W.
• This dimmer switch supports single-pole or 3-way applications. In a 3-way circuit, only one dimmer switch can be installed.
• Do not use with fans or non-dimmable lighting.
• UL Listed for safety and quality assurance.

3. Package Contents

Verify that all components are present before beginning installation:

• BESTTEN Dimmer Light Switch(es)
• Decorator Wall Plate(s)
• Mounting Screws
• Wire Nuts (typically included, though not explicitly listed in "whats_in_the_box", it's standard for electrical components)

4. Installation

Important: Turn off power at the circuit breaker before installation. This dimmer switch does not require a neutral wire, making it suitable for older electrical systems.

4.1. Single-Pole Wiring

For single-pole installations, the dimmer controls the light from one location.

1. Turn off power at the circuit breaker.
2. Remove the existing switch from the wall box.
3. Connect the Hot (Black) wire from the wall box to the black wire on the dimmer.
4. Connect the Load (Black) wire to the red wire on the dimmer.
5. Connect the Ground (Green or bare copper) wire from the wall box to the green wire on the dimmer.
6. Secure the dimmer into the wall box and attach the wall plate.
7. Restore power at the circuit breaker.

4.2. 3-Way Wiring

For 3-way installations, the dimmer controls the light from two locations. Only one dimmer switch can be installed in a 3-way circuit; the other switch should be a standard 3-way switch.

1. Turn off power at the circuit breaker.
2. Identify the common wire (often black) on your existing 3-way switch. This will be your line or load wire. Mark it for future reference.
3. Identify the two traveler wires (often red). Mark them.
4. Remove the existing switch from the wall box.
5. Connect the common (line or load) wire to the black wire on your new dimmer.
6. Connect the two traveler wires to the two red wires on your new dimmer.
7. Connect the Ground (Green or bare copper) wire from the wall box to the green wire on the dimmer.
8. Secure the dimmer into the wall box and attach the wall plate.
9. Restore power at the circuit breaker.

5. Operation

The BESTTEN Dimmer Light Switch features an on/off rocker switch and a horizontal slider for dimming control.

• On/Off Control: Press the top or bottom of the large rocker switch to turn the lights on or off.
• Dimming Control: Use the small horizontal slider located below the rocker switch to adjust the brightness level. Slide it to the left for dimmer light and to the right for brighter light.
• Memory Function: The dimmer remembers the last dimmed light setting and will turn on to that exact light level when activated.

7. Troubleshooting

7.1. Eliminating Flickering

If your lights flicker, hum, or buzz, especially with LED or CFL bulbs, the dimming range may need adjustment. This dimmer has an adjustable dimming range to optimize performance.

1. Turn on the switch and move the slide dimmer to the lowest (leftmost) setting.
2. Rotate the SIDE ADJUSTMENT WHEEL (Sensitivity Dial) counter-clockwise all the way up.
3. Slowly rotate the SIDE ADJUSTMENT WHEEL (Sensitivity Dial) clockwise down until the preferred lowest light level is achieved and the lights are no longer flickering.

Note: If the dial stops in either direction, do not continue to turn it. For best compatibility and to minimize flickering, use high-quality, brand-name dimmable bulbs and fixtures.
