Please read before installing
Important Notes
- Install in accordance with all national and local electrical codes.
- When no “grounding means” exists in wallbox, the National Electrical Code (NEC®) allows a control to be installed as a replacement when a plastic faceplate with plastic fasteners is used, or the circuit is protected by a ground fault circuit interrupter (GFCI). Lutron wallplates meet this requirement. Cap or remove green wire before screwing control into wallbox.
- Protect the control from dust and dirt when painting or spackling the wall.
- Clean the dimmer with a soft damp cloth only. Do not use any chemical cleaners.
- For indoor use only.
- In any 3-way/4-way circuit, use only one main control with up to 4 companions.
- Maximum wire length between the main control and the farthest companion is 150 ft (45 m).
