5. Installation and Setup
Follow these steps for safe and proper installation:
- Turn Off Power: Locate your circuit breaker panel and turn off the power to the switch box you will be working on. Verify power is off using a voltage tester.
- Remove Existing Switch: Carefully remove the wall plate and unscrew the existing switch from the wall box. Disconnect the wires from the old switch.
- Identify Wires: Identify the Line (hot), Load, Ground, and Traveler wires (if applicable for 3-way installations). This dimmer does not require a neutral wire for operation.
- Prepare Wires: Strip approximately 1/2 inch (12.7 mm) of insulation from each wire end. The dimmer includes a strip gauge on the back for reference.
- Connect Wires using Lever Edge Terminals:
- Ground Wire (Green): Insert the bare copper ground wire into the green Lever Edge terminal.
- Line/Load Wires (Black/Red): Insert the Line (hot) wire into the black Lever Edge terminal. Insert the Load wire into the TRAV1 (red) terminal. For 3-way installations, refer to the wiring diagrams below for traveler connections.
The Lever Edge terminals are color-coded for easy identification and accept 12 gauge and 14 gauge solid or stranded copper wire. Push the wire firmly into the terminal until you hear an audible 'click', confirming a secure connection. No exposed metal parts ensure added safety.

- Mount Dimmer: Carefully push the wired dimmer into the wall box. Secure it with the mounting screws provided.
- Install Wall Plate: Attach the decorative wall plate (sold separately) over the dimmer. The dimmer is designed with a tongue and groove alignment for quicker trim-out on multi-gang installations.
- Restore Power: Return to your circuit breaker panel and turn the power back on.

6. Operation
The Leviton ESL01-1LW dimmer switch provides both ON/OFF control and smooth dimming functionality.
- Turn ON/OFF: Press the top of the rocker switch to turn the lights ON to the previously set brightness level. Press the bottom of the rocker switch to turn the lights OFF.
- Dimming: Move the vertical slide control up to increase the light brightness. Move the slide control down to decrease the light brightness. The separate ON/OFF rocker switch ensures that your preferred dimming level is maintained when the lights are turned off and on again.

7. Adjusting Dimming Performance
The dimmer includes a setup button to fine-tune its performance with various dimmable LED/CFL bulbs, helping to prevent flickering and optimize the dimming range.
- Setup Button: An easily accessible setup button allows for adjustments to customize performance, such as setting the minimum dim level and maximum bright levels. This ensures superior dimming performance and compatibility with a wide range of LED bulbs.
- Consult the detailed instructions provided with the dimmer for specific steps on adjusting these settings.

8. Wiring Diagrams
8.1. Single Pole Installation
A single-pole installation controls lights from one location.
- Connect the Line (Hot) wire to the BLACK terminal.
- Connect the Load wire to the TRAV1 terminal.
- Connect the Ground wire to the GREEN terminal.
- The TRAV2 terminal is not used in a single-pole configuration.
Image: This diagram illustrates the wiring connections for a single-pole installation, showing the dimmer controlling a light from one location.
8.2. 3-Way Installation
A 3-way installation controls lights from two separate locations. This requires the Leviton dimmer switch and a standard 3-way switch.
- At the dimmer location: Connect the Line (Hot) wire to the BLACK terminal. Connect the Load wire to the TRAV1 terminal. Connect the Ground wire to the GREEN terminal.
- Connect the two Traveler wires between the dimmer's TRAV1 and TRAV2 terminals and the corresponding traveler terminals on the standard 3-way switch.
- At the 3-way switch location: Connect the common terminal of the 3-way switch to either the Line or Load, depending on which box the power source enters. Connect the two traveler wires to the remaining two terminals. Connect the Ground wire.

9. Maintenance
The Leviton ESL01-1LW dimmer switch requires minimal maintenance.
- Cleaning: To clean the dimmer switch, gently wipe it with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or internal components.
- Inspection: Periodically inspect the dimmer and wall plate for any signs of damage or loose connections. If any issues are found, turn off power at the circuit breaker before attempting to address them.
