•  Use only one (1) dimmer per load. For remote operation, use Leviton Remote, Cat. No. TT00R-1.
  Do not use a 3-way switch.
•  Use with incandescent or 120V halogen fixtures only.

Tools needed to install your Dimmer:

Slotted/Philips Screwdriver 

Electrical Tape

Pliers 

 

 

Pencil

Cutters 

 

 

Ruler

Changing the color of your Dimmer:

Your Dimmer includes two color options. The Dimmer ships with the 

White frame attached. To change color of frame, proceed as follows:

When installing more than one dimmer in the same location, the side 

sections of the mounting strap must be removed. Use pliers to carefully 

bend side sections back and forth until they break off. The side sections 

dissipate heat, so removing them requires a derating of the dimmer’s 

capacity 

(refer to chart).

Installing Dimmer by itself or with other devices:

If installing Dimmer in a single device application, proceed with the 

INSTALLING YOUR DIMMER

 section. If installing Dimmer in a multi-

device application, proceed as follows:

MULTI-DEVICE APPLICATION:

NOTE: 

You only need to remove side sections if installing with other 

dimmers or if it does not fit in wall box – not when installing with 

mechanical switches.

Single-Pole:

 

Look at the back of your switch. 

If there are 2 wires connected 

to  two screw terminals (not 

including a green or bare copper 

wire used for grounding), you 

have a Single-Pole switch. 

3-Way:

 

Look at the back of your switch.

If there are 3 wires connected 

to  three screw terminals (not 

including a green or bare copper 

wire used for grounding), you 

have a 3-Way switch. 

DO NOT 

add a single-pole switch in this 

location.

INSTALLING YOUR DIMMER

NOTE:

 Use check boxes       when Steps are completed. 

WARNING:

 To avoid fire, shock, or death; 

TURN OFF 

POWER

 at circuit breaker or fuse and test that power is off 

before wiring!

Step 1

Removing existing switch:

 Remove existing  

 

wallplate and switch mounting screws. Carefully pull switch  

from wall box. DO NOT remove wires attached to the switch  

at this time.

Identifying your wiring application (most common):

NOTE:

 If the wiring in the wall box does not resemble any of  

these configurations, consult a qualified electrician.

Disconnecting switch wires and preparing wires:

•  Disconnect wires from screw terminals or 

Quickwire™ slots (shown).

•  Pull off pre-cut insulation from Dimmer leads.
•  Make sure that the ends of the wires from the 

wall box are 

straight (cut if necessary).

•  Remove 5/8" (1.6 cm) of insulation from each 

wire in the wall box (shown).

• 

For Single-Pole Application, go to Step 5a.

•  For 3-Way Application, go to Step 5b.
