Looking after your new National Luna Fridge or Freezer

Learn more about caring and maintaining your new National Luna fridge or freezer.

The National Luna range of portable camping & mobile fridges have been optimised for 4×4 and recreational use. The full range boasts superior cooling power, ultra high efficiency and the convenience of running on 12-volt, 24-volt or 230 volt. Here are some useful tips to caring for your new purchase.


  • In a vehicle you can tie your fridge down with a tension tie-down. However a base mounting plate (sold separately) is recommended for most units.
  • Do not leave loose cans rolling around, as these can damage the cooling inner bin.
  • Do not carry corrosive or solvent-containing substances in the fridge.

Connection and usage

  • Ensure that the correct type of cable and connectors are used for installation.
  • The cable to the battery should be at least 4mm in diameter. Its length should be as short and uninterrupted as possible.
  • Do not use a damaged power lead.
  • Do not connect the refrigerator to a power source that does not comply with the input power specifications displayed on the fridge’s rear panel.
  • Allow a 50mm gap around the refrigerator compressor area for ventilation.
  • Keep the appliance as full as possible for the best cooling results.
  • Do not use any electrical appliance inside the cooling compartment.

Storage essentials

  • When storing the fridge, ensure that the lid is propped open to allow for aeration.
  • Disconnect the appliance from an electrical source. (Note: When the fridge is switched off, the interior light will still function if the unit is connected to a power source)

Energy-saving tips

  • Mount the appliance in a cool, dry place away from sunlight.
  • Cool the unit down on 220V, before placing it in your vehicle for 12V/24V use.
  • Recommended temperature usage: 4'C for refrigeration and -6'C to -10'C for freezing.
  • Allow food to cool or freeze before storing it in the appliance
  • Avoid leaving the lid or door open any longer than necessary.

Careful cleaning

  • Keep the unit clean with a soft cloth moistened with lukewarm water, but ensure that no water drops into the seals.
  • Never use abrasive or solvent-based materials when cleaning the cooling tank.
  • Never use hard or sharp tools to remove ice from the evaporator or cooling tank.
