4. Setup & Installation
Follow these steps carefully to install your Leviton 1222-2W Double-Pole AC Quiet Switch. Ensure all safety precautions are observed.
Tools Required:
- Screwdriver (Phillips and Flathead)
- Wire Strippers/Cutters
- Voltage Tester
- Electrical Tape (optional)
Installation Steps:
- Turn Off Power: Locate the circuit breaker or fuse that controls the power to the switch location. Turn it OFF. Use a voltage tester to confirm that the power is completely off at the switch box.
- Remove Old Switch (if applicable): Carefully remove the wall plate and unscrew the old switch from the electrical box. Disconnect the wires from the old switch, noting their positions.
- Prepare Wires: If necessary, strip approximately 1/2 inch (12.7 mm) of insulation from the ends of the circuit wires. Ensure wire ends are clean and straight.
- Identify Terminals: The Leviton 1222-2W switch has four terminals for line and load connections, plus a green grounding screw. For a double-pole switch, there will be two 'LINE' terminals (for incoming power) and two 'LOAD' terminals (for outgoing power to the device). The switch is marked 'LINE' and 'LOAD' on the back.
- Connect Ground Wire: Connect the bare copper or green insulated ground wire from the electrical box to the green grounding screw on the switch. Tighten securely.
- Connect Line Wires: Connect the two incoming hot (usually black) wires from the power source to the two 'LINE' terminals on the switch. You can use either the side screw terminals or the back-wire holes. Tighten screws firmly if using side terminals.
- Connect Load Wires: Connect the two outgoing hot (usually black) wires leading to the fixture or appliance to the two 'LOAD' terminals on the switch. Tighten screws firmly.
- Mount the Switch: Carefully fold the wires into the electrical box, leaving enough room for the switch. Secure the switch to the electrical box using the provided mounting screws.
- Install Wall Plate: Attach the wall plate over the switch.
- Restore Power: Turn the power back ON at the circuit breaker or fuse box. Test the switch to ensure proper operation.

6. Maintenance
The Leviton 1222-2W switch is designed for long-term, maintenance-free operation under normal conditions. However, periodic checks can help ensure continued safety and performance:
- Cleaning: To clean the switch and wall plate, wipe with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure power is off before cleaning.
- Inspection: Periodically inspect the switch and wall plate for any signs of damage, such as cracks, discoloration, or loose connections. If any damage is observed, turn off power and replace the switch.
- Tightness: If the switch feels loose in the wall box, turn off power and gently tighten the mounting screws. Do not overtighten.
7. Troubleshooting
If you experience issues with your Leviton 1222-2W switch, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch does not turn ON/OFF power. | No power to the circuit; Loose wiring connection; Faulty switch. | Check circuit breaker/fuse. Turn off power, check all wire connections for tightness. If connections are secure, replace the switch. |
| Switch feels warm to the touch. | Overload on the circuit; Loose wiring connection; Internal fault. | Immediately turn off power. Reduce load on the circuit. Check wiring connections for tightness. If problem persists, replace the switch. |
| Toggle is stiff or difficult to move. | Dust or debris; Internal mechanism issue. | Turn off power and gently clean around the toggle. If stiffness continues, replace the switch. |
If troubleshooting steps do not resolve the issue, contact Leviton customer support or a qualified electrician.
