Setup
- Unpacking: Carefully remove the cooler from its packaging. Retain packaging for future transport or storage.
- Placement: Place the cooler on a firm, level surface. Ensure adequate ventilation around the unit, especially the compressor area. Avoid direct sunlight or heat sources.
- Power Connection: Connect the DC cable to the cooler's power input. Then, connect the other end to a 12V or 24V DC power source (e.g., vehicle cigarette lighter socket).

Operating Instructions
- Power On/Off: The unit powers on automatically when connected to a power source. To turn off, disconnect the power cable.
- Temperature Setting: Use the 'Temperature' rotary dial to set the desired cooling level. Turning towards 'COLD' increases cooling (lower temperature), and towards 'FREEZE' enables deep freezing down to -18°C.
- Battery Monitor: The 'Battery Monitor' switch protects your vehicle battery from excessive discharge. Select 'HIGH' for sensitive batteries (e.g., starting batteries) or 'LOW' for less sensitive batteries (e.g., leisure batteries). The unit will switch off if the battery voltage drops below the selected threshold.
- Loading the Cooler: Place items inside the cooler. For optimal performance, pre-cool items if possible. The internal divider can help organize contents.

- Ventilation: Periodically check that the ventilation grilles are free from dust and debris to ensure efficient operation.
- Storage: When not in use for extended periods, ensure the cooler is clean and dry. Store with the lid slightly ajar to prevent odors.
Troubleshooting
