Before You Begin: Ensure power is turned off at the circuit breaker or fuse box to avoid electrical shock. Verify power is off using a voltage tester.

1. Prepare Wiring: Carefully remove the existing wall switch from the electrical box. Identify the existing wires: typically a hot wire (power in), a load wire (to the light/device), a neutral wire, and a ground wire.
2. Connect Wires: Connect the Westek TMDW10 timer's wires to your home's electrical wires according to the following scheme:
   • Black Wire (Timer) to Hot Wire (from power source)
   • Red Wire (Timer) to Load Wire (to light/device)
   • White Wire (Timer) to Neutral Wire
   • Green Wire (Timer) to Ground Wire

   Use appropriate wire connectors (not included) to secure all connections. Ensure no bare wire is exposed.

3. Mount Timer: Carefully fold the wires into the electrical box and secure the timer to the box using the provided screws.
4. Install Wall Plate: Attach a standard wall plate (not included) over the timer.
5. Restore Power: Turn the power back on at the circuit breaker.
