5. 安裝指南

This recirculating pump system is designed for easy installation with standard tank water heaters. It does not require a dedicated return line.

5.1 安裝前檢查清單

• Ensure the main water supply and water heater power are turned off.
• Drain a small amount of water from the hot water line to relieve pressure.
• Confirm you have all necessary tools (e.g., wrenches, pipe thread sealant).
• Verify the system is compatible with your tank water heater. Not for tankless systems.

5.2 泵安裝

1. 確定安裝點： The pump should be installed on the hot water outlet pipe of your tank water heater.
2. 連接幫浦： Use the quick-install connectors to attach the recirculating pump to the hot water outlet. Ensure the flow arrow on the pump aligns with the direction of hot water flow out of the heater. The union fittings allow for rotation-free installation.
3. 安全接線： The system features reinforced wiring for heat conditions. Ensure all electrical connections are secure and protected.

5.3 Bypass Valve Installation

The adjustable bypass sensor valve should be installed under the sink furthest from the water heater, or at a central point in your hot water loop, to ensure efficient recirculation.

1. Identify Faucet: Choose the faucet furthest from your water heater.
2. Disconnect Supply Lines: Turn off the water supply to the faucet. Disconnect the existing hot and cold water supply lines from the faucet stems.
3. Install Bypass Valve: Connect the bypass valve to the hot and cold water supply lines under the sink using the provided 20-inch faucet water supply lines and adapters. Ensure the valve is oriented correctly (hot to hot, cold to cold). The bypass technology allows cold water to push cooled hot water back to the heater.
4. 檢查是否有洩漏： 緩慢打開總水閥，檢查所有連接處是否有漏水。

6. 操作說明

6.1初始啟動

1. After installation and leak checks, restore power to the water heater and the recirculating pump.
2. Open a hot water faucet until water flows consistently, ensuring air is purged from the lines.
3. The pump will begin circulating water.

6.2 Adjusting Bypass Valve Temperature

The bypass valve allows you to set the desired hot water temperature range for recirculation.

• The adjustable temperature range is 68-140°F (20-60°C).
• Rotate the dial on the bypass valve to select your preferred temperature. The valve will open to recirculate water when the line temperature drops below this setting and close when it reaches the set temperature.

6.3 Pump Speed Control

The recirculating pump features three speed settings to adjust flow rate and power consumption:

• 設定 1： 46W (5.3 GPM) - Lower power, suitable for smaller homes or less frequent hot water demand.
• 設定 2： 85W (7.9 GPM) - Medium power, balanced performance.
• 設定 3： 100W (10.5 GPM) - Higher power, for faster hot water delivery or larger plumbing systems.

Adjust the switch on the pump housing to select the desired speed.

6.4 Wi-Fi Smart Plug Operation

The included Wi-Fi Smart Plug allows for scheduled operation, optimizing energy use and hot water availability.

1. Connect Smart Plug: Plug the recirculating pump into the Wi-Fi Smart Plug, then plug the smart plug into a standard electrical outlet.
2. 應用程序設置： Download the compatible smartphone application (refer to smart plug instructions for specific app details). Follow the in-app instructions to connect the smart plug to your 2.4GHz Wi-Fi network.
3. Schedule Operation: Use the app to program daily or weekly start/stop cycles for the pump. This allows you to have instant hot water during peak usage times (e.g., mornings) and conserve energy when not needed. The smart plug also offers voice control (via Alexa or Google Home), timing/countdown functions, power failure memory, and energy monitoring.

7、維護保養

Regular maintenance ensures the longevity and efficient operation of your recirculating pump system.

• 濾網清洗： The bypass valve includes a removable filter screen. Periodically inspect and clean this screen to prevent debris buildup, which can affect performance. Turn off water supply before removing and cleaning the screen.
• 洩漏檢查： Regularly inspect all connections for any signs of leaks. Address any leaks immediately to prevent water damage.
• 一般清潔： Keep the exterior of the pump and smart plug clean and free of dust and debris. Use a soft, damp 用抹布擦拭。請勿使用研磨性清潔劑。
• 防凍（如果適用）： In cold climates, ensure pipes are adequately insulated to prevent freezing, especially if the pump is installed in an unheated area. The system helps prevent frozen pipes by circulating warm water.
