1. はじめに
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Danfoss 25T65 EN 60730-2-9 thermoregulator. This device is designed to control the temperature within a refrigerator by sensing the internal temperature via its capillary tube and activating or deactivating the cooling system accordingly. Please read this manual thoroughly before installation and use.
2. 安全情報
Always observe the following safety precautions to reduce the risk of electric shock, injury, or damage to the product or appliance.
- 電源を切る: Always disconnect the refrigerator from the main power supply before attempting any installation, maintenance, or troubleshooting.
- 有資格者： Installation and electrical connections should ideally be performed by a qualified technician. If performing DIY, ensure you have adequate knowledge of electrical systems and refrigerator components.
- 電気接続: すべての電気接続が安全であり、地域の電気規則に準拠していることを確認してください。
- 毛細管: Handle the capillary tube with care. Do not bend it sharply, kink it, or damage its insulation, as this can affect its temperature sensing accuracy.
- 環境条件: Do not expose the thermoregulator to excessive moisture or extreme temperatures outside its operating range.
3. セットアップとインストール
The Danfoss 25T65 thermoregulator is a replacement part for refrigerators. Proper installation is crucial for its correct function.
- 準備： Disconnect the refrigerator from the power supply. Access the existing thermoregulator, typically located near the temperature control knob inside the refrigerator compartment or behind a control panel.
- 古いユニットの削除: Carefully disconnect the electrical wires from the old thermoregulator. Note their positions or take a photograph for reference. Gently remove the capillary tube from its sensing location, usually attached to the evaporator coil or a designated sensing pocket.
- 新しいユニットの取り付け: Mount the new Danfoss 25T65 thermoregulator in the same location as the old unit. Ensure it is securely fastened.
- 毛細管の配置: Carefully route the 0.8-meter capillary tube to the exact same sensing location as the original. The tip of the capillary tube must be in proper contact with the evaporator or sensing area for accurate temperature readings. Avoid sharp bends or kinks in the tube.
- 電気接続: Connect the electrical wires to the terminals of the new thermoregulator. Refer to the markings on the unit and your previous notes/photos to ensure correct polarity and connection points. The unit features standard spade terminals for connection.
4. 操作手順
Once installed, the thermoregulator operates automatically to maintain the set temperature.
- 温度設定: The thermoregulator typically features a rotary shaft (often connected to a knob on the refrigerator's control panel) that allows you to adjust the desired temperature. Turning the knob usually moves between 'Min' (warmer) and 'Max' (colder) settings.
- 自動操作: The device senses the temperature through its capillary tube. When the temperature rises above the set point, it activates the refrigerator's compressor. When the temperature drops to the set point, it deactivates the compressor.
- 初期起動: After installation, plug in the refrigerator. Allow several hours for the refrigerator to reach the set temperature and stabilize.
5. メンテナンス
The Danfoss 25T65 thermoregulator is a sealed unit and requires minimal maintenance. However, periodic checks can help ensure its longevity and proper function.
- 電源切断: Always disconnect power to the refrigerator before performing any maintenance.
- 目視検査: Periodically inspect the thermoregulator and its connections for any signs of wear, corrosion, or damage.
- 毛細管: Ensure the capillary tube remains securely in its sensing location and is not damaged or kinked.
- クリーニング： If necessary, gently wipe the exterior of the thermoregulator with a dry, soft cloth. Do not use liquid cleaners or solvents.
6。 トラブルシューティング
If your refrigerator is not maintaining temperature correctly after installing the thermoregulator, consider the following common issues:
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| 冷蔵庫が冷えない | Incorrect wiring; faulty thermoregulator; capillary tube dislodged or damaged. | Check electrical connections. Ensure capillary tube is correctly placed. If connections and placement are correct, the thermoregulator may be faulty and require replacement. |
| Refrigerator overcooling | Thermoregulator set too low; faulty thermoregulator; capillary tube not sensing correctly. | Adjust temperature setting. Verify capillary tube placement. If problem persists, the thermoregulator may be faulty. |
| 冷蔵庫が常に動いている | Thermoregulator not reaching cut-off temperature; capillary tube dislodged or damaged. | Check capillary tube placement. Ensure refrigerator door seals are intact. If the issue persists, the thermoregulator may be faulty. |
| 冷蔵庫の電源が入らない | No power; faulty thermoregulator; incorrect wiring. | Check power supply to the refrigerator. Verify electrical connections to the thermoregulator. If power is present and wiring is correct, the thermoregulator may be faulty. |
If you are unable to resolve the issue after following these steps, it is recommended to contact a qualified appliance repair technician.
