Installing a 12V Fridge
How to install your 12V Fridge
Step 1: Measure Your Cut Out Space
A 12V Fridge may vary in size and dimensions relative to the cut out or recess dimensions.
Eg: Sometimes a fridge may have a narrower cut out required than the overall width of the fridge. This is to allow for frames, doors and the overall shape of the fridge.
You can find the cut out required for your fridge in the installation manual.
Step 2: Frame Or No Frame?
Some fridge models will include a mounting frame. These are often for trim purposes and will not supply the full structural support required to securely mount the fridge in place.
Step 3: Ventilation
Compressors work best when they are not too cool or too hot. Air needs flow over the compressor and out a vent. Excessive heat is bad for the compressor and also the efficiency of the fridge.
Generally speaking any fridge under the capacity of 100L will require one vent at the top of the fridge. Larger fridges will require two vents, one at the top and another at the bottom to achieve optimal airflow.
Step 4: Electrical
A 12V fridge can vary in voltage input configurations, some fridges will include 240V operation. The 240V is relatively easy and can be plugged into a New Zealand plug.
When no battery power is available and you need to run from a 240V power source, you will need to choose the appropriate adapter for your fridge. It is best to leave your fridge connected to your battery system and charge the battery directly from a battery charger.
When wiring your 12V you must consult the operator’s manual for correct cable/fuse size. Cables size will vary depending on voltage and length of cable.
