The Evakool Down Under Series DU47-SZ is a portable fridge/freezer designed for cooling and freezing items, suitable for recreational use. It features a robust design with a Secop compressor and a multi-voltage system, making it versatile for various power sources.
Function Description:
The DU47-SZ functions as a portable refrigerator or freezer, capable of maintaining temperatures between +10°C and -18°C. It utilizes a world-renowned Secop compressor and a highly efficient rollbond evaporator to ensure effective cooling. The unit can be powered by a multi-voltage system (DC12-24 Volts) or an included 240V AC adaptor, offering flexibility for use in vehicles or with mains power. A key feature is its digital battery protection system, which safeguards the vehicle battery from excessive discharge. The unit is designed to be user-friendly with a digital control panel for temperature settings and mode selection.

- These modes can be selected by pressing the SET button twice and then using the + and - buttons.
- Battery Protection Mode: A three-stage battery protection system (Low, Medium, High) prevents excessive discharge of the vehicle battery. This mode is set by pressing the SET button three times and then using the + and - buttons. The manual recommends "H" for starter batteries and "L" for auxiliary batteries or AC power supply.
- Connectivity: The fridge can be connected to a 12V or 24V DC power source using an Anderson style inlet plug and a 12/24V connection cable. It also includes a 240V adaptor for AC power supply.
- Cable Specification: The manual provides a table for recommended DC cable thickness based on length to ensure optimal performance and prevent voltage drop.
- Pre-chilling: It is recommended to pre-chill the fridge before use to achieve the desired temperature quicker.
- Ventilation: Good ventilation is crucial, with a recommended gap of at least 200mm around the vents.
- Baskets: The included baskets help ensure free air circulation around the cabinet.
Maintenance Features:
- Cabinet Care: The interior and exterior should be cleaned after every use with a damp cloth and a mild non-abrasive detergent, then dried thoroughly. Painted metal surfaces can be polished with car polish. Scourers, harsh cleaning products, solvents, or oil should be avoided as they can damage plastic and painted surfaces.
- Defrosting: After use, the unit should be switched off and disconnected from the power source to allow ice to melt naturally. The lids should be left open, and any residue should be drained and wiped dry with a towel. The cabinet must be completely dry before storage to prevent corrosion, mold, or odor.
- Condenser Cleaning: Regular cleaning of the fridge helps prevent frosting of cooling plates and ensures the condenser is free of dust and lint.
- Professional Inspection: A general inspection and maintenance by an approved EvaKool agent is recommended every 12 months, as portable appliances are subjected to various operating conditions.
- Fuse Replacement: Instructions are provided for replacing the fuse plug (10 Amp glass fuse) in a cigarette-style 12V plug, if applicable.
- PCB (Display) Light Replacement: Instructions are given for replacing the PCB light, with spare parts available from EvaKool.
Safety Instructions:
- Avoid touching exposed cables.
- Do not use the fridge if connections are wet.
- Ensure proper fusing at the battery or power source when used in a vehicle.
- DC power system installations should be handled by a qualified professional.
- Verify source voltage matches technical data.
- Do not place electrical devices inside the refrigerator due to moisture risk.
- Never clean with a hose or submerge in liquid.
- Avoid placing near heat sources.
- Place on a flat surface and secure in a vehicle.
- Not designed for marine purposes; corrosion from sea salt may void warranty.
- Never handle plugs and switches with wet hands or while standing on a wet surface when connecting to 240V AC.
Troubleshooting:
The manual provides solutions for common issues such as the appliance not turning on (checking power supply, connections, fuse, circuit breaker), food being frozen (temperature setting too low), bad refrigeration performance (inappropriate temperature, open/unlocked lid, broken seal, poor ventilation, too much/warm product, heat source nearby), and unusual noises (uneven surface, loose parts). Error codes (E1-E6) are also detailed with corresponding reasons and solutions, covering low voltage, fan issues, compressor start issues, low compressor speed, high ambient temperature, and thermistor problems.
