5. Operating Instructions
The chiller features an easy-to-use digital display for temperature control.
- Power On/Off: Use the "One key switch" located on the unit to turn the chiller on or off. The digital display will illuminate.
- Set Target Temperature:
- Press the SET button once. The current target temperature will flash on the display.
- Use the Up (▲) and Down (▼) buttons to adjust the temperature to your desired setting.
- Press SET again to confirm the setting, or wait a few seconds for it to save automatically.
- Set Temperature Difference (F1 Code): This setting determines the temperature range within which the chiller operates, preventing frequent on/off cycling.
- Long press the SET button until "F1" appears on the display.
- Press SET again to enter the F1 setting.
- Use the Up (▲) and Down (▼) buttons to adjust the temperature difference. A common setting is 3-5 degrees Fahrenheit. For example, if your target is 75°F and F1 is set to 5, the chiller will activate when the water reaches 80°F and cool down to 75°F.
- Press SET to confirm and exit.

- Cooling Operation: Once the settings are configured, the chiller will automatically begin cooling when the water temperature exceeds the set target temperature plus the F1 difference. It will stop cooling once the target temperature is reached.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your chiller.
- Clean Air Vents: Periodically inspect and clean the air intake and exhaust vents to prevent dust and debris buildup, which can hinder heat dissipation. Use a soft brush or vacuum cleaner.
- Check Hoses and Connections: Regularly inspect hoses for kinks, cracks, or leaks. Ensure all connections are secure.
- Water Pump Maintenance: Clean the water pump regularly according to its own instruction manual to ensure unobstructed water flow.
- Environmental Conditions: Maintain the recommended 6-inch clearance around the chiller for efficient operation. Avoid placing it in excessively humid or dusty environments.
