User Manual for Compass Compressor Cooling Box 12/24/230V

Quick guide from the manual

The Compass Compressor Cooling Box is a versatile portable cooler capable of operating on 12/24V DC (vehicle) or 110-240V AC (mains) power. It features adjustable battery protection, ECO and Quick Cooling modes, and a reversible door opening mechanism. Ensure the unit is placed on a flat surface with adequate ventilation (200mm at the back, 100mm at the sides) before use.

Power supply and connection

The unit can be powered via 12/24V DC or 110-240V AC. When connecting to a vehicle, ensure the voltage is within the correct range. If using the unit in a boat, installation should be handled by qualified personnel. Always ensure the plug and socket have a good connection.

Operation settings

Use the control panel to manage the cooling box:

• ON/OFF: Press to start or turn off the unit.
• UP/DOWN buttons: Adjust the target temperature.
• SET button: Press to enter economy running mode or to configure settings.
• Modes: Select between ECO (Energy-saving) and HH (Quick cooling).

Indicator lights:

• Power indicator (Red): Compressor stopped.

• Eco/Max indicator (Red): Quick cooling mode active.

Battery protection

To prevent draining your vehicle battery, the unit features three levels of battery protection (L, M, H). When the unit is running, press the SET button for 3 seconds to select the level. We recommend setting this to (H) when connected to a car. If the F1 error code appears, adjust the protection level from H to M or L.

Adjusting the door opening

The door opening direction can be adjusted:

1. Use a cross screwdriver to remove the stainless chain.
2. Remove the two hinges.
3. Install the hinges on the opposite side between the door and the tank.
4. Install the stainless chain on the opposite side.

Food storage and defrosting

Freezer (below -20°C): Cut meat and wrap tightly. Do not store fresh and frozen food together. Do not place glass containers with sealed liquids in the freezer.

Refrigerator (0°C to 10°C): Store eggs, butter, milk, and bottled drinks. Keep fruit and vegetables in the crisper. Allow hot food to cool before placing it inside.

Defrosting: If frost builds up, unplug the unit, open the door, and let the ice thaw. Use a shovel to remove ice; do not use sharp metal tools.

Care and cleaning

Unplug the unit before cleaning. Use a soft cloth dampened with warm water and neutral detergent to wipe inner and outer surfaces. Dry with a clean soft cloth. Do not use corrosive cleansers, scouring powder, or bleach. Keep the unit in a ventilated place and leave the door slightly open if storing for a long period.
