Setup
- Unpacking: Carefully remove the refrigerator from its packaging. Inspect for any damage.
- Initial Placement: Place the refrigerator on a flat, stable surface. Allow it to stand upright for at least 6 hours before connecting to power, especially if it was transported horizontally. This allows the compressor oil to settle.
- Ventilation: Ensure adequate ventilation around the unit. Maintain a minimum clearance of 10 cm (4 inches) on all sides for proper heat dissipation.
- Power Connection:
- AC Power (Home/Office): Connect the AC adapter to the refrigerator's AC input, then plug the power cable into a standard 100-240V AC wall outlet.
- DC Power (Vehicle): Connect the DC power cable to the refrigerator's DC input, then plug the other end into your vehicle's 12V or 24V cigarette lighter socket.

Battery Protection System:
The unit includes a three-level battery protection system (High, Medium, Low) to prevent excessive discharge of your vehicle's battery. You can select the desired level via the control panel or the app.
- High (H): Provides maximum protection for your vehicle battery, cutting off power at a higher voltage.
- Medium (M): A balanced setting for most uses.
- Low (L): Allows for longer operation from the vehicle battery before cutoff, but with less battery protection.
Refer to the table below for approximate cutoff voltages:
| Level | DC 12V Cut Out | DC 12V Cut In | DC 24V Cut Out | DC 24V Cut In |
|---|---|---|---|---|
| HIGH | 11.1V | 12.4V | 24.3V | 25.7V |
| MID | 10.1V | 11.4V | 22.3V | 23.7V |
| LOW | 8.5V | 10.9V | 21.3V | 22.7V |
