11. DEFROSTING
12. COOLING TIPS
Defrosting needs to be completed when ice inside the Upright Fridge/Freezer is around 5mm thick. Ice on the
inside walls will affect the normal operation of the device.
Set the thermostat to 0 and remove items from inside the Upright Fridge/Freezer.
Do not use mechanical devices, metallic, sharp objects, or other means to accelerate the defrosting process.
Do not attempt to manually remove the ice, allow air flow to naturally melt the ice.
How full should your fridge be? It comes down to energy; pull energy out of something and it gets cooler, put
energy in and it gets warmer. Think of a kettle, put energy by turning it on, the water gets hotter, turn the kettle
off and energy is released from the water and the water gets cooler. Water vs Air, water takes around 4 times
more energy to cool down compared to air.
Therefore, filling a fridge with liquid instead of leaving empty will take noticeably longer to cool down and use
more power. This is one big reason why pre-cooling your fridge is strongly recommended.
Every time you open your fridge, cool air will be pulled out and replaced with warm and moist air. So initially
your empty fridge will get cooler quicker, but anytime you open the lid to place or remove items the fridge will
take time to get back down to temperature.
The optimum point ends up being around ½ to ¾ full of product. This fills most of the fridge and reduces air
lost each time the lid is opened but also leaves enough room for air flow around the product inside the fridge.
Air flow around products is also important for keeping all the product inside the unit at similar temperatures
and makes for a more efficient fridge.
If you tightly pack product, it could take days for the product at the center to correctly come down to
temperature. This will also have a negative effect on power usage.
13. GENERAL TIPS
1. Pre-chill before trips.
2. If the fridge will be accessed frequently (drinks fridge for example) aim to have around ¾ loaded.
3. If you need more items to fill up space, you can use empty reusable containers. (e.g. take-away
containers) They are easy to stack and help with air-flow around products.
4. Keep the fridge out of direct sunlight.
5. Keep the vents of the fridge at least 150mm clear from any obstructions.
