Setpower MC20 21QT Portable 12V Car Refrigerator and Freezer User Manual

1. Important Safety Information

Please read all safety instructions carefully before operating the Setpower MC20 portable refrigerator/freezer. Failure to follow these instructions may result in product damage or personal injury.

• Ensure the unit is placed on a stable, level surface. The MC20 is engineered to operate normally at angles up to 40 degrees, but optimal performance and safety are achieved on level ground.
• Always secure the refrigerator using the provided fixed ropes, especially when used in moving vehicles like SUVs, trucks, RVs, or vans, to prevent dangerous shifting during transit.
• Maintain adequate ventilation around the unit. Do not block the air vents on the sides or back of the refrigerator to ensure proper heat dissipation and efficient operation.
• Do not immerse the unit in water or expose it to excessive moisture.
• Keep the refrigerator away from direct heat sources or flammable materials.
• When connecting to a vehicle's 12V/24V DC power, utilize the 3-level battery protection system to prevent excessive battery drain. Set the protection level (High, Medium, Low) according to your vehicle's battery health and usage needs.
• If an E1 error occurs, it may indicate an improper battery protection setting or low input voltage. Adjust the battery protection level or recharge the power source.

4.2 Temperature Settings and Cooling Performance

The MC20 can function as both a refrigerator and a freezer, with a temperature range of -4°F to 68°F (-20°C to 20°C).

• Fast Cooling: The unit can cool from 77°F (25°C) to 32°F (0°C) in approximately 15 minutes. It can reach its lowest temperature of -4°F (-20°C) in about one hour.
• Refrigerator Mode: Ideal for keeping items fresh, typically set between 32°F and 68°F (0°C to 20°C). Suitable for vegetables, fruits, beverages, and dairy products.
• Freezer Mode: For freezing items, typically set between -4°F and 32°F (-20°C to 0°C). Suitable for meat, shrimp, fish, and ice cream.

4.3 Battery Protection System

The MC20 is equipped with a smart 3-stage battery protection system to prevent your vehicle's battery from draining completely. You can select one of three modes:

• High Mode: Provides the highest level of battery protection, cutting off power at a higher voltage. Recommended for starting batteries.
• Medium Mode: A balanced protection level.
• Low Mode: Allows for longer operation before cutoff, suitable for deep cycle or auxiliary batteries.

The compressor will shut off when the measured DC voltage drops below the 'Cut Out' value for the selected mode and will restart when the voltage rises above the 'Cut In' value.

5. Maintenance

Regular maintenance ensures optimal performance and longevity of your Setpower MC20 refrigerator/freezer.

• Cleaning: Clean the interior and exterior surfaces with a damp cloth and mild detergent. Do not use abrasive cleaners or solvents. Ensure the unit is unplugged before cleaning.
• Defrosting: The unit features an automatic defrost system. If ice buildup occurs, manually defrost by turning off the unit and allowing the ice to melt. Drain any water through the drain plug if available.
• Ventilation: Periodically check that the air vents are clear of dust and debris. Use a soft brush or vacuum cleaner to gently clean the vents.
• Storage: When not in use for extended periods, ensure the unit is clean and dry. Store with the lid slightly ajar to prevent odors and mildew.

6. Troubleshooting

If you encounter issues with your MC20, refer to the following common problems and solutions:

• Unit Not Turning On:
  • Check power connections (DC or AC) to ensure they are secure.
  • Verify the power source is active and providing sufficient voltage.
  • If using DC power, check the vehicle's battery voltage. The battery protection system may have cut off power due to low voltage. Adjust the protection level or recharge the battery.
• Not Cooling Effectively:
  • Ensure the lid is properly closed and sealed.
  • Check for obstructions around the ventilation areas.
  • Verify the temperature setting on the control panel.
  • Allow sufficient time for the unit to reach the desired temperature, especially when starting from a warm state. Pre-chilling items before placing them in the unit can improve efficiency.
• E1 Error Displayed:
  • This typically indicates a low input voltage. Adjust the battery protection setting to a lower level (e.g., from High to Medium or Low) or connect to a power source with higher voltage.
  • If the issue persists, consult the warranty and support section.
• Unusual Noise:
  • The MC20 operates quietly (below 42dB). If you hear unusual or loud noises, ensure the unit is on a stable surface and not vibrating against other objects.
  • Check for any loose components or debris inside the unit.
