5. Opsætning og installation
The Moonshan recirculating system is designed for straightforward installation. Ensure you have basic plumbing tools and follow these steps. If unsure, consult a professional plumber.
5.1 System overview
The system consists of the recirculating pump installed at the hot water heater and a sensor valve installed under the furthest sink from the water heater. The sensor valve uses bypass technology to return cooled water from the hot water line back to the water heater via the cold water line for reheating.

5.2 Pump Installation at Water Heater
- Turn off Water and Power: Shut off the main water supply to your home and the power to your water heater.
- Drain Hot Water Line: Open a hot water faucet at the highest point in your home to relieve pressure and drain some water from the hot water tank.
- Installer pumpe: Connect the recirculating pump to the hot water outlet of your tank water heater. Ensure all connections are sealed with Teflon tape and tightened appropriately to prevent leaks.
- Tilslut forsyningsledninger: Use the provided 20-inch PEX supply lines to connect the pump to the existing hot water plumbing.
5.3 Sensor Valve Installation Under Sink
- Identify Furthest Faucet: Locate the hot water faucet furthest from your water heater.
- Disconnect Supply Lines: Disconnect the hot and cold water supply lines from the shut-off valves under the sink.
- Install Sensor Valve: Connect the stainless steel sensor valve between the hot and cold water supply lines under the sink. The valve is marked for hot and cold connections. Use the provided adapters, gaskets, and Teflon tape for a secure, leak-free connection.
- Reconnect Faucet Lines: Reconnect the faucet's hot and cold supply lines to the sensor valve.


5.4 sidste trin
- Genopret vand og strøm: Slowly turn on the main water supply. Check all connections for leaks. Restore power to the water heater.
- Udluft luft: Open a hot water faucet until water flows steadily, indicating air has been purged from the lines.
6. Betjening
6.1 3-Speed Control
The recirculating pump features a 3-speed control switch, allowing you to adjust the flow rate based on your household's needs. The power consumption varies with the speed setting:
- Hastighed 1: 46W
- Hastighed 2: 85W
- Hastighed 3: 100W
Select a speed that provides satisfactory hot water delivery without excessive noise or energy consumption. The maximum flow rate is 10.5 GPM with a maximum head of 20 feet.

6.2 Wi-Fi Smart Plug
The included Wi-Fi smart plug replaces manual timing, allowing you to schedule pump operation via your smartphone. This ensures hot water is available when needed, reducing waiting times and saving water.
- Connect Smart Plug: Plug the recirculating pump into the Wi-Fi smart plug, then plug the smart plug into a standard electrical outlet.
- Download app: Download the compatible smart home application (e.g., Tuya Smart, Smart Life) to your smartphone.
- Par enhed: Follow the in-app instructions to pair the smart plug with your home's 2.4GHz Wi-Fi network.
- Indstil tidsplaner: Use the app to create schedules for the pump to turn on and off. For example, you can set it to run before you typically wake up or during peak hot water usage times.
- Stemmestyring: The smart plug is compatible with voice assistants like Alexa and Google Home, allowing for convenient voice control.

6.3 Sensor Valve Functionality
The stainless steel sensor valve monitors the water temperature in the hot water line. If the temperature drops below 104°F, the valve opens, allowing the cooler water to return to the water heater through the cold water line for reheating. Once the water reaches 104°F, the valve closes. This process ensures hot water is readily available at the faucet without affecting the cold water supply.

7. Vedligeholdelse
Regular maintenance helps ensure the longevity and efficient operation of your recirculating pump system.
- Filter Screen Cleaning: The stainless steel sensor valve includes a removable filter screen. Periodically inspect and clean this screen to prevent debris buildup that could impede water flow or valve operation.
- Lækageinspektion: Regularly check all plumbing connections for any signs of leaks. Address any leaks promptly to prevent water damage.
- Generel rengøring: Keep the exterior of the pump and smart plug clean and free of dust. Use a soft, damp klud til rengøring. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Vinterisering: In colder climates, the pump can help prevent hot water pipes from freezing. However, ensure proper insulation for all exposed pipes to maximize protection.
