1. Important Safety Information
Please read all safety warnings and instructions carefully before using the appliance to prevent injury or damage.
- Initial Setup: After unpacking, allow the cooler to stand upright for at least 12 hours before connecting it to a power source. This allows the refrigerant to settle.
- Power Supply: Use only the specified power adapters (12V/24V DC or 100-240V AC). Ensure the voltage matches the cooler's requirements.
- Ventilation: Ensure adequate air circulation around the cooler. Do not block the ventilation openings. Maintain a minimum clearance of 10 cm on all sides.
- Placement: Place the cooler on a stable, level surface. Avoid direct sunlight, heat sources, or damp environments.
- Water and Moisture: Do not expose the cooler to rain or excessive moisture. Do not immerse it in water.
- Cleaning: Always unplug the cooler from the power source before cleaning or performing any maintenance.
- Children: This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.
- Damage: Do not operate the cooler if the power cord or plug is damaged, or if the appliance itself is malfunctioning or has been dropped. Contact customer support for assistance.

- Connect Power:
- DC Power (12V/24V): Connect the DC power cable to the cooler's DC input port and then to your vehicle's cigarette lighter socket or a compatible 12V/24V power source.
- AC Power (100-240V): Connect the AC power adapter to the cooler's AC input port, then plug the adapter into a standard wall outlet.
The cooler supports various power inputs: 12V/24V DC for vehicles, 100-240V AC for home use, and can be connected to solar panels or portable power stations for outdoor adventures.
- Install Divider (Optional): If you wish to use the dual-zone feature, insert the removable divider into the designated slot inside the cooler. This creates two separate compartments for different temperature settings.

4. Operating Instructions
4.1 Basic Operation:
- Power On/Off: Press and hold the power button on the control panel to turn the cooler on or off. The LED display will illuminate.
- Set Temperature: Use the '+' and '-' buttons on the control panel to adjust the desired temperature. The display will show the set temperature. The cooler will automatically adjust to reach and maintain this temperature.
- Switch Modes (MAX/ECO): Press the 'SET' button to cycle between MAX (fast cooling) and ECO (energy-saving) modes. MAX mode is recommended for rapid cooling, while ECO mode is for sustained operation with lower power consumption.
- Battery Protection: Press and hold the 'SET' button for 3 seconds to cycle through battery protection levels: L (Low), M (Medium), H (High). This feature prevents the cooler from draining your vehicle's battery. 'M' is suitable for most situations. 'H' is recommended when connected to a car battery.
- Temperature Unit: Press the 'SET' button briefly to switch between Celsius (°C) and Fahrenheit (°F).
- Memory Function: The cooler will remember your last temperature setting when powered off and on again.
The KROAK cooler in ECO mode demonstrates superior energy efficiency, consuming significantly less power per day compared to other models.
4.2 Dual-Zone Operation:
When the divider is installed, the cooler can operate as two separate zones. The control panel typically adjusts the temperature for the main compartment, and the app provides independent control for both zones.
The KROAK cooler features a versatile dual-zone design, allowing users to configure separate fridge and freezer compartments to meet diverse storage needs.
4.3 App Control:
Once the app is downloaded, enable Bluetooth on your smartphone and open the app. The app will guide you through pairing with your cooler. Through the app, you can:
- Monitor real-time temperatures of both zones.
- Adjust temperatures for each zone independently.
- Switch between MAX and ECO modes.
- Lock/unlock the control panel.
- Access additional settings and information.
The KROAK cooler's Bluetooth app allows for convenient remote operation, enabling users to control settings and monitor temperatures directly from their smartphone, even when the cooler is in a vehicle.
5. Maintenance
5.1 Cleaning:
- Always unplug the cooler before cleaning.
- Use a soft cloth dampened with mild detergent and water to clean the interior and exterior surfaces.
- Do not use abrasive cleaners, harsh chemicals, or sharp objects, as these can damage the surfaces.
- For thorough cleaning, remove the divider and use the drain plug to empty any accumulated water.
- Ensure all surfaces are completely dry before reconnecting power.
5.2 Storage:
- If storing for an extended period, ensure the cooler is clean and dry.

6. Troubleshooting
If you encounter issues with your KROAK cooler, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Cooler not turning on. | No power, loose connection, damaged power cord. | Check power connections. Ensure power outlet/vehicle socket is working. Try a different power source. Inspect power cord for damage. |
| Cooler not cooling effectively. | Blocked ventilation, lid not sealed, ambient temperature too high, ECO mode selected. | Ensure vents are clear. Check lid seal. Move cooler to a cooler environment. Switch to MAX mode for faster cooling. |
| Unusual noise during operation. | Cooler not level, fan obstruction. | Place cooler on a level surface. Check for any objects obstructing the fan. Normal compressor noise is around 45 dB. |
| Bluetooth app connection fails. | Bluetooth off, cooler not in pairing mode, interference. | Ensure cooler is powered on. Enable Bluetooth on your phone. Reset Bluetooth: Press and hold the Power button and the 'SET' button simultaneously for 3 seconds on the cooler's control panel. Then restart the connection process in the app. |
