BEFORE YOU BEGIN:
This device REQUIRES a ground; if a ground is not available, contact a
qualified electrician. If you are not experienced and familiar with electrical
wiring and electrical codes, contact a qualified electrician. Some codes
require installation by a qualified electrician. Install in accordance with all
national and local codes. Ensure the existing switch and light is working
prior to installing the new switch.
1. Disconnect power at the circuit breaker or fuse box BEFORE
proceeding.
2. Remove the wall plate and set aside for re-assembly.
REMOVE OLD WALL SWITCH:
1. Remove switch from switch box.
2. During removal, identify or label the load and line wires.
NOTE: Typically a line wire is the incoming hot wire from the circuit breaker.
The load wire is the wire supplying power between the switch and the light.
3. Keep all load wires separated from line wires.
INSTALL NEW SWITCH (Figure 1):
1. Identify the antenna routing (Figure 1).
2. Connect the wires (Figure 2). NOTE: If your wiring includes a neutral
wire this wire is not required, combine neutral wire(s) and cap with
wire nut (not provided).
• Green wire to ground.
Connect the green wire on the new switch to the exposed copper
ground, green wire, or to the ground connection within metal
switch box. NOTE: If ground doesn’t exist contact an electrician
to add a ground. This product will not function without a proper
ground.
• Red wire to load.
• Black wire to line.
3. Secure connections with a wire nut and wrap each wire nut with
electrical tape.
NOTE: Turn all wire nuts clockwise, making sure the bare wires are covered.
Tug on each wire nut to make sure the connections are good.
4. Carefully pack the wiring back into switch box. Make sure the wires are
not pinched or strained. Make sure the antenna is hanging straight
down between the switch box and the drywall.
5. Fasten the remote light switch to the switch box with the screws
(provided).
6. Fasten the wall plate securely over the switch box with the original
screws from the wall plate.
TEST
1. Turn on the power to circuit at fuse box or circuit breaker.
2. Test the light switch, manually press the light switch to ensure the
light is functional (Figure 3). If it is not functional, see
