- Attach one end of the clear water pipe to the chiller's inlet connector.
- Attach the other end of this pipe to the outlet of your water pump.
- Attach a second clear water pipe to the chiller's outlet connector.
- Direct the other end of this second pipe into your fish tank or ice tub.
- Water Pump Placement: Place the water pump inside your fish tank or ice tub, ensuring it is fully submerged.
- System Diagrams: Refer to the diagrams below for suggested usage configurations.
- Power Connection: Plug the chiller's power cable into a suitable electrical outlet (220V/50Hz or 110V depending on model).
4. Operating Instructions
The LG-CY500 chiller can be operated via its touch screen interface or the included remote control.
4.1 Power On/Off
- Press the "POWER" button on the touch screen or the red power button on the remote control to turn the unit on or off.
4.2 Temperature Setting
To adjust the desired water temperature:
- Touch Screen: Use the "UP" and "DOWN" arrows on the touch screen to set the target temperature. The display will show the current and target temperatures.
- Remote Control: Use the "UP" and "DOWN" buttons on the remote control to adjust the target temperature.
4.3 Mode Selection
The chiller may offer different operating modes (e.g., cooling, fan). Refer to the icons on the touch screen for available modes and select as needed.
5. Maintenance
Regular maintenance ensures optimal performance and longevity of your chiller.
- Clean Fan Vents: Periodically check and clean the fan heat dissipation vents on the side of the unit to prevent dust buildup, which can hinder cooling efficiency. Use a soft brush or vacuum cleaner.
- Check Water Connections: Regularly inspect all water pipe connections for any signs of leaks or loose fittings. Tighten if necessary.
- Water Pump Cleaning: Clean the water pump regularly to prevent blockages from debris, which can reduce water flow and strain the chiller.
- Evaporator Coil: The evaporator uses a pure titanium coil for corrosion resistance, requiring minimal maintenance. However, ensure the water circulating through it is clean to prevent scale buildup.
6. Troubleshooting
If you encounter issues with your chiller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chiller not turning on | No power, loose connection, power switch off. | Check power cable, ensure it's plugged in securely. Verify the power switch on the unit is in the "ON" position. |
| Water not cooling | Incorrect temperature setting, insufficient water flow, clogged fan vents, ambient temperature too high. | Adjust target temperature lower. Check water pump for blockages and ensure it's running. Clean fan vents. Ensure the chiller is in a well-ventilated area. |
| Water leaks | Loose pipe connections, damaged pipes or seals. | Inspect all pipe connections and tighten them. Check pipes and seals for damage and replace if necessary. |
| Excessive noise | Unit not level, fan obstruction, internal component issue. | Ensure the unit is on a flat, stable surface. Check fan for any obstructions. If noise persists, contact customer support. |
If the problem persists after trying these solutions, please contact customer support.

8. User Tips
- For optimal cooling, ensure the chiller is placed in a location with good air circulation and away from direct sunlight or heat sources.
- Always ensure the water pump is fully submerged and free from obstructions to maintain consistent water flow.
- Monitor the water temperature regularly, especially during initial setup, to ensure it stabilizes at your desired level.
- Consider using an external filter in conjunction with the chiller for aquariums to maintain water quality and prevent debris from entering the chiller's system.
- The low noise operation makes it suitable for living areas, but ensure it's not directly against a wall that could amplify vibrations.
