4.2 電気接続
Connect the DHG2 anti-frost device to your main pool electrical panel. The device typically requires a dedicated power supply. Refer to the detailed wiring diagram provided inside the device cover for specific connection points and ensure all connections are secure and properly insulated. It is recommended to use appropriate conduit for wiring.
The CTN temperature probe must be installed in a location that accurately measures the pool water temperature, typically within the filtration circuit or a dedicated probe well. Ensure the probe is fully immersed in water for accurate readings.

5. 操作
5.1 初期電源投入
Once installed and wired, switch on the main power supply to the DHG2 device. The digital display will illuminate, showing the current water temperature measured by the CTN probe.
5.2 Setting the Anti-Frost Threshold
The DHG2 allows you to set a specific temperature threshold. When the water temperature falls below this set point, the device will automatically activate the pool's filtration pump to circulate water and prevent freezing.
- Press the 'SET' button on the control panel. The display will show the currently programmed anti-frost activation temperature.
- Use the 'Up' and 'Down' arrow buttons to adjust the desired temperature threshold. A common setting is between 0°C and 3°C (32°F and 37.4°F).
- Press 'SET' again to confirm and save the new setting. The display will then revert to showing the current water temperature.
5.3 Forced Circulation Mode
The DHG2 may include a forced circulation mode, which can be manually activated. This mode ensures continuous water movement and increases pressure within the pipes, further lowering the freezing point of the water. This can be particularly useful during extreme cold snaps or for specific maintenance procedures.
Refer to the device's specific button layout for activating this mode, which is typically a dedicated button or a combination of existing buttons (e.g., holding an arrow button for a few seconds).
6. メンテナンス
Regular maintenance ensures the optimal performance and longevity of your CCEI DHG2 Anti-Frost Device.
- 目視検査: Periodically inspect the device, wiring, and connections for any signs of wear, corrosion, or damage.
- クリーニング： Keep the digital display and control buttons clean and free from dust or debris. Use a soft, dry cloth for cleaning.
- プローブチェック: Ensure the CTN temperature probe is clean and properly positioned in the water for accurate readings. Remove any buildup that might affect its sensitivity.
- 冬季保管（該当する場合）: If the device is removed for off-season storage, ensure it is stored in a dry, protected environment.
7。 トラブルシューティング
This section provides solutions to common issues you might encounter with your DHG2 device.
