2. Safety Information

Please observe the following safety precautions to prevent injury or damage to the product.

• Always disconnect the power supply before performing any maintenance, installation, or cleaning.
• Ensure the chiller is placed on a stable, level surface.
• Maintain at least 6 inches (15 cm) of clear space around the chiller for adequate heat dissipation. Blocking vents can lead to overheating and reduced performance.
• Do not operate the chiller if the power cord or plug is damaged.
• Do not immerse the main chiller unit in water. The water pump is submersible, but the chiller unit is not.
• This appliance is for indoor use only.
• Keep out of reach of children.
• Use a Ground Fault Circuit Interrupter (GFCI) for all electrical connections to prevent electrical shock.

4. Setup Instructions

Follow these steps for proper installation of your aquarium chiller.

1. Positioning the Chiller: Place the chiller on a flat, stable surface near your aquarium or hydroponic system. Ensure there is at least 6 inches (15 cm) of clear space around all sides for optimal airflow and heat dissipation.
2. Prepare Connectors: Gather the provided connectors, including the white sealing washers.
3. Install Inlet/Outlet Nozzles:
   • Insert a white sealing washer onto each inlet/outlet nozzle.
   • Place the pipe joint into the black nut cap.
   • Tighten the black nuts onto the chiller's inlet and outlet ports.
4. Connect Water Pump: Attach one end of the water pipe to the outlet of the submersible water pump. Secure it with a clamp if necessary.
5. Connect Chiller to System:
   • Connect the other end of the water pipe from the pump to the chiller's inlet port.
   • Connect a second water pipe from the chiller's outlet port back to your aquarium or hydroponic system.
   • Ensure all connections are secure and watertight to prevent leaks.
6. Submerge Pump: Place the submersible water pump into your aquarium or hydroponic reservoir. Ensure it is fully submerged and positioned to draw water effectively.
7. Power Connection: Plug the chiller's power cord into a GFCI-protected electrical outlet. Plug in the water pump's power cord.

5. Operating Instructions

The chiller features a digital control panel for temperature setting and calibration.

5.1. Power On/Off

Locate the power switch on the back of the unit. Flip the switch to the 'ON' position to power on the chiller. The digital display will illuminate.

Figure 8: Power switch. This image shows the main power switch located on the rear panel of the chiller unit.

5.2. Temperature Setting (Assumed Target Temperature Range: 75-79°F)

The chiller will begin cooling after a 2-3 minute power-on delay. To adjust the target temperature:

1. Set Shutdown Temperature: Press the Set key. Use the ▲ (up) or ▼ (down) arrow keys to adjust the desired shutdown temperature (e.g., 77°F). Press the Rst key to save.
2. Set Starting Temperature (F1 Code): Long press the Set key until the F1 code appears. Then, press the Set key again. Use the ▲ or ▼ arrow keys to adjust the temperature difference (e.g., to 4°F for a working range of 4°F).

Figure 9: Temperature setting and F2 calibration. This image provides a visual guide to setting the shutdown temperature and adjusting the F1 code for the working temperature range, as well as the F2 calibration process.

5.3. F2 Calibration Setting

If the chiller's displayed temperature does not match an external thermometer, you can calibrate it:

1. Long press the Set key to display F1. Press the ▲ key to display F2. Press Set again.
2. Use the ▲ or ▼ arrow keys to adjust the offset value (e.g., to 5 if the chiller reads 77°F and the actual temperature is 72°F, meaning a -5 adjustment is needed). Press Rst to return to the current temperature display.

6. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your chiller.

• Clean Air Vents: Periodically check and clean the air intake and exhaust vents to prevent dust and debris buildup, which can impede heat dissipation. Use a soft brush or vacuum cleaner.
• Inspect Hoses and Connections: Regularly check hoses and connections for any signs of leaks, kinks, or damage. Replace damaged components immediately.
• Clean Water Pump: Disconnect power to the pump and remove it from the water. Disassemble and clean the impeller and pump housing to remove any algae or debris that may affect water flow.
• Water Quality: Maintain good water quality in your aquarium or hydroponic system to reduce the buildup of contaminants in the chiller's internal components.

7. Troubleshooting

If you encounter issues with your chiller, refer to the following common problems and solutions.
