4. セットアップとインストール
Follow these steps carefully to install your Leviton 1222-2W Double-Pole AC Quiet Switch. Ensure all safety precautions are observed.
必要なツール:
- ドライバー（プラスとマイナス）
- ワイヤーストリッパー/カッター
- 巻tageテスター
- 絶縁テープ（オプション）
インストール手順:
- 電源を切る: 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.
- 古いスイッチを削除します（該当する場合）。 Carefully remove the wall plate and unscrew the old switch from the electrical box. Disconnect the wires from the old switch, noting their positions.
- ワイヤーを準備する： 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.
- 端末を識別します: 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.
- アース線を接続する: 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.
- 負荷線を接続する: 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.
- スイッチを取り付けます。 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.
- ウォールプレートの取り付け: Attach the wall plate over the switch.
- 電力を回復する： Turn the power back ON at the circuit breaker or fuse box. Test the switch to ensure proper operation.

5. 操作
The Leviton 1222-2W is a simple ON-OFF toggle switch. To operate:
- スイッチをつける： Push the toggle lever to the 'ON' position (typically upwards).
- 電源を切るために： Push the toggle lever to the 'OFF' position (typically downwards).

6. メンテナンス
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:
- クリーニング： To clean the switch and wall plate, wipe with a soft, damp 布で拭いてください。研磨剤入りの洗剤や溶剤は使用しないでください。清掃前に必ず電源を切ってください。
- 検査： 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.
- 締め付け感: If the switch feels loose in the wall box, turn off power and gently tighten the mounting screws. Do not overtighten.
7。 トラブルシューティング
If you experience issues with your Leviton 1222-2W switch, refer to the following common problems and solutions:
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| Switch does not turn ON/OFF power. | 回路に電力が供給されていない、配線の接続が緩んでいる、スイッチに障害がある。 | 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. |
