5. Setup Instructions
- Placement: Position the chiller on a flat, stable surface. Ensure there is at least 6 inches (15 cm) of clear space around all sides of the unit to allow for proper air circulation and heat dissipation. Avoid placing it in direct sunlight or in an enclosed cabinet.
- Connect Water Pump: Attach the provided water pump to the inlet of your aquarium or hydroponic system.
- Connect Water Pipes: Connect one end of the 3-meter water pipe to the outlet of the water pump and the other end to the "IN" port of the chiller. Connect a second pipe (not included, or use the remaining length of the provided pipe if suitable) from the "OUT" port of the chiller back to your aquarium or system. Secure all connections with the provided clamps to prevent leaks.
- Submerge Pump: Place the water pump fully submerged in the water of your aquarium or hydroponic reservoir.
- Fill System: Ensure your aquarium or system is filled with water to the appropriate level.
- Power Connection: Once all connections are secure and the pump is submerged, plug the chiller's power cord into a grounded electrical outlet.

6. Operating Instructions
The chiller features a digital control panel for easy temperature management.
- Power On: After connecting the power, the chiller will power on. The digital display will show the current water temperature.
- Setting Shutdown Temperature (F1):
- Press the "Set" button once. The display will show "F1".
- Use the "Up" or "Down" arrows to adjust the desired shutdown temperature. This is the temperature at which the chiller will stop cooling.
- Press "Set" again to confirm and save the setting.
- Setting Startup Temperature (F2):
- Press the "Set" button twice. The display will show "F2".
- Use the "Up" or "Down" arrows to adjust the desired startup temperature. This is the temperature at which the chiller will begin cooling again.
- Press "Set" again to confirm and save the setting.
- Temperature Adjustment (F3 - Calibration):
- Press the "Set" button three times. The display will show "F3".
- This setting allows for calibration if there is a discrepancy between the actual water temperature and the temperature displayed on the unit. Use the "Up" or "Down" arrows to adjust the offset.
- Press "Set" again to confirm and save the setting.
- Cooling Operation: The chiller will automatically activate when the water temperature rises above the set startup temperature (F2) and will stop when it reaches the set shutdown temperature (F1).

7. Maintenance
- Regular Cleaning: Periodically clean the exterior of the chiller with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Air Vents: Ensure the air intake and exhaust vents are free from dust and debris. Blocked vents can hinder heat dissipation and reduce efficiency. Use a soft brush or vacuum cleaner to gently clear any obstructions.
- Water Pump: Clean the water pump regularly to prevent blockages and ensure optimal water flow. Refer to the water pump's specific instructions for cleaning.
- Water Pipes: Inspect water pipes for any signs of algae buildup or blockages. Clean as necessary to maintain unrestricted water flow.
- Coil Inspection: The pure titanium coil atomizer is designed for durability. However, if you notice a significant drop in cooling performance, consult a professional.

8. Troubleshooting
- Chiller Not Turning On:
- Check if the power cord is securely plugged into a working electrical outlet.
- Verify that the power switch on the unit (if present) is in the "ON" position.
- Ensure there is no power outage in your area.
- Chiller Not Cooling Effectively:
- Confirm that the set temperature (F1) is lower than the current water temperature.
- Check for obstructions in the air vents and clean them if necessary (refer to Maintenance section).
- Ensure the water pump is operating correctly and water is flowing through the chiller.
- Verify that the cooling water volume does not exceed the chiller's capacity (300L for AL-300).
- Check for any kinks or blockages in the water pipes.
- Unusual Noise or Vibration:
- Ensure the chiller is placed on a stable, level surface.
- Check for any loose components or foreign objects near the fans.
- While some compressor noise is normal, excessive noise may indicate an issue. Contact support if it persists.
- Water Leakage:
- Immediately unplug the unit.
- Inspect all pipe connections and ensure they are tightly secured with clamps.
- Check for any cracks or damage to the pipes or chiller housing.
