3. Setup and Installation
This thermoelectric cooler requires a water circulation system for effective heat dissipation. Follow the diagram below for proper connection.
- Connect Water Pump: Connect a water pump to circulate water through the cooler.
- Water Box Connection: Ensure the water pump draws water from a water box or reservoir.
- Cooler Inlet/Outlet: Connect the water pump output to the cooler's inlet and the cooler's outlet to the heat dissipation unit or back to the water box. The system is designed to transfer heat from the "cold water" side to the "hot water" side, which then needs to be dissipated.
- Power Connection: Connect the 3-pin power connector to a DC12V power source. Ensure the power source can supply the required 48A maximum current. The red wire is typically positive (+), and the black wire is negative (-).

Important Safety Note: Do not plug in power without water circulation for heat dissipation. Operating the device without proper cooling can lead to overheating and damage.
4. Operating Instructions
Once the system is properly set up with water circulation and power connected, the thermoelectric cooler will begin to operate.
- Power On: Apply DC12V power to the unit. The fans on the cooler will activate, and the Peltier elements will begin to create a temperature differential.
- Cooling Effect: The cooling effect depends on several factors, including the size of the cooling space, ambient temperature, heat insulation, and the sealability of the system.
- Temperature Difference: Under optimal conditions, the system can achieve a temperature difference between 8-13 degrees Celsius.
- Recommended Cooling Space: The support space for effective cooling is typically 1-2 cubic units (e.g., cubic feet or cubic meters, depending on the application scale).

5. Maintenance and Care
Regular maintenance ensures optimal performance and longevity of your Hilitand Thermoelectric Cooler.
- Clean Fans and Heat Sinks: Periodically inspect and clean the cooling fans and heat sink fins to prevent dust buildup, which can impede airflow and reduce cooling efficiency. Use compressed air or a soft brush.
- Check Water Circulation: Ensure the water pump is functioning correctly and there are no blockages in the water lines. Clean the water box and replace water as needed to prevent algae or mineral buildup.
- Inspect Connections: Regularly check all electrical and water connections for tightness and signs of wear or leakage.
- Avoid Dry Operation: Never operate the unit without adequate water circulation. This can cause the Peltier elements to overheat and fail.
