5. Setup Instructions
Follow these steps to properly set up your Poafamx Aquarium Chiller:
- Connect Water Pipes: Connect the water pipes to the water inlet and outlet ports on the chiller. Ensure a secure connection to prevent leaks. The inlet and outlet ports have no distinction, meaning either can be used for inflow or outflow.
- Position Temperature Sensor: Place the water temperature sensor fully into the aquarium or water tank. Ensure it is submerged and positioned to accurately measure the water temperature.
- Connect Power: Connect the power adapter to the DC12V interface on the chiller. Then, plug the power adapter into a suitable electrical outlet. The chiller will power on and begin operation.

6. Operating Instructions
The chiller features a digital display and control buttons for setting the desired water temperature.
- Power On/Off: The unit powers on automatically when connected to electricity. Disconnect from power to turn off.
- Temperature Display: The digital screen displays the current water temperature measured by the probe.
- Setting Temperature: Press the 'SET' button to enter temperature setting mode. Use the 'UP' and 'DOWN' arrow buttons to adjust the desired temperature. Press 'SET' again to confirm and exit the setting mode. The chiller will then work to maintain the water temperature within the set range.
- Automatic Operation: The chiller will automatically activate cooling when the water temperature rises above the set point and deactivate when it reaches the desired temperature.
7. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your chiller.
- Cleaning the Unit: Periodically wipe the exterior of the chiller with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Clear Air Vents: Ensure the air inlet and outlet vents are free from dust and debris. Use a soft brush or vacuum cleaner to gently clean them, ensuring proper airflow for heat dissipation.
- Check Water Connections: Regularly inspect water pipes and connections for any signs of leaks or wear. Replace damaged pipes immediately.
- Temperature Probe: Keep the temperature probe clean to ensure accurate readings. Gently wipe off any algae or buildup.
- Storage: If storing the chiller for an extended period, ensure it is clean and dry. Store in a cool, dry place away from direct sunlight.
8. Troubleshooting
If you encounter issues with your chiller, refer to the following common problems and solutions:
- Chiller not turning on:
- Check if the power adapter is securely plugged into both the chiller and the electrical outlet.
- Ensure the electrical outlet is functional.
- Verify the power adapter is not damaged.
- Water temperature not cooling to set point:
- Ensure the air inlet and outlet vents are not blocked, allowing for proper heat dissipation.
- Verify the chiller's power rating is appropriate for your water volume and ambient room temperature. Larger volumes or higher ambient temperatures may require more powerful cooling.
- Check if the temperature probe is fully submerged and clean for accurate readings.
- Ensure water flow through the chiller is within the recommended range (1-3 L/min).
- Water leaks from connections:
- Tighten all water pipe connections.
- Inspect pipes for cracks or damage and replace if necessary.
- Unusual noise during operation:
- Ensure the chiller is placed on a stable, level surface.
- Check if any internal components are loose or if the fan is obstructed. If the noise persists and is severe, discontinue use and contact support.
- Inconsistent operation (turns on/off frequently):
- This could indicate the chiller is struggling to maintain temperature due to environmental factors or an undersized unit for the tank volume.
- Ensure proper ventilation around the unit.
If the problem persists after attempting these solutions, please contact customer support.
