INSTALLATION

Multi-Gang Installations:
When installing more than one control in the same wall box, it may be necessary to remove all the inner side sections prior to wiring. Using pliers, bend each needed side section up and down until it breaks off.

Dimmer Capacity:
600W unmodified
500W if one side is removed
400W if both sides are removed

1. Do Not Remove Outside Sections
2. Each Control Has Inside Sections Removed
3. Middle Control Has Two Side Sections Removed

STEP 1 Turn OFF Power :

STEP 2 Identify Your Wiring Application (most common):

NOTE: If the wiring in the wall box does not resemble any of these configurations, consult an electrician.

Single-Pole

1. Line (Hot)
2. Neutral
3. Ground
4. Load

3-Way

1. Line or Load Common
   (See important instructions below)

2. Neutral

3. Ground

4. First Traveler

5. Second Traveler

IMPORTANT: For 3-way applications, note that one of the screw terminals from the old switch being removed will usually be a different color (Black) or labeled Common. Tag that wire with electrical tape and identify it as the common (Line or Load) in both the dimmer wall box and the standard 3-way switch wall box. The remaining two wires on the brass or lighter screw terminals of the old switch are the travelers.

STEP 3 Prepare Wires:

• Pull off the pre-cut insulation from the Dimmer wires.
• Make sure that the ends of the wires from the wall box are straight (cut if necessary).

STEP 4A Single Pole Wiring Application:

1. This wire is used in 3-Way installations only, For single pole installations, do not remove this insulating label.
2. Insert wires straight then twist clockwise
3. Electrical Tape

Connect wires as follows:

Screw wire nuts on clockwise making sure no bare conductors show below the wire connectors. Secure each connector with electrical tape.

1. Green dimmer wire connects to Ground or bare copper wire.
2. Black dimmer wire connects to Line Hot wire.
3. Red dimmer wire without insulating label connects to Load wire.
4. Remaining red dimmer wire should have an insulation label affixed.

DO NOT REMOVE it in a single pole application.

1. 120VAC 50/60Hz
2. Hot (Black)
3. Neutral (White)
4. Ground (Green)
5. Red

STEP 4B 3 Way Wiring Application:

1. Insert wires straight then twist clockwise
2. Electrical Tape

Connect wires as follows:

Screw wire nuts on clockwise making sure no bare conductors show below the wire connectors. Secure each connector with electrical tape.

1. Green dimmer wire connects to Ground or bare copper wire.
2. Black dimmer wire connects to Line Hot or Load (Common) wire.
3. Two Red dimmer wires connects to the two travelers.

1. 120VAC 50/60Hz
2. Hot (Black)
3. Neutral (White)
4. Red
5. Ground (Green)
6. Black

STEP 5 Dimmer Mounting:

Installation may now be completed by carefully positioning all the wires to provide room in the wall box for the dimmer. Mount the dimmer into the box with supplied mounting screws.

STEP 6 Turn ON Power:

STEP 7 Test Dimmer:

NOTE: If using the dimmer in a 3-way application, the lights will turn ON at brightness set on the dimmer’s slide control lever. The lights can be controlled from either the dimmer or the switch location.

ON/OFF:
Depress button switch to ON position
– Lights will turn ON
Depress button switch to OFF position
– Lights will turn OFF
BRIGHTEN & DIM:
Move the slider control lever
– Lights will BRIGHTEN or DIM

STEP 8 Adjust Dimming Range (optional):

Adjust dimming range as follow steps:

1. Turn on the dimmer and move the slider all the way to the rightmost for full brightness. See Fig. A.

2. Slowly move the silder to the left until the preferred lowest light level is achieved and the light output is stable for all bulbs. Leave the slider there (Fig. B).

3. Press and hold the fine tune button (Fig. C) until the dimming indicator blinks 3 times (Fig. D).

4. Move the slider all the way to the leftmost position. The light will be dimmed to the preferred lowest light level set in the above step 2.

5. ON/OFF SWITCH

6. FINE TUNE BUTTON
