Tips and tricks for electronic refrigerator :

  1. The closer to the thermoelectric element inside the cooler, the better the cooling effect is.
  2. For very cold drinks, the icing effect is better with aluminum canned drinks.
  3. For fresh fruits (e.g. watermelon), cut the fruit into smaller pieces first, and then cover them with cling film and put the flat surface close to the inner wall of the refrigerator.
  4. For a ready meal, put the meal in a metal dish first, and then cover it with cling film and put it on the base of the unit close to the inner wall of the refrigerator.
  5. For refrigeration of cosmetic items or skin care products, put them in the middle or lower shelf, the closer to the thermoelectric cooler, the better the cooling effect is.

Temperature reference for refrigeration and fresh

  1. When items are put into the refrigerator for cold storage, the temperature in the refrigerating chamber should be between 3-8°C to keep quality and flavor and prolong freshness.
  2. The colder the ambient temperature is, the colder the unit will operate internally, for example, an unheated room would possibly make the items freeze internally.
  3. Recommended keeping the room ambient above 18°C and below 25°C for best operation. Ensure ventilation at all times.

What can I keep in my Subcold product?

Anything you wish to keep cold!

Can I leave my Subcold Mini Fridge plugged in every day, 24 hours per day?

Can I adjust the thermostat on my cooler/warmer?

No adjustment can be made to the temperature setting. This is due to the thermoelectric design and the PELTIER effect

Can my mini fridge keep things frozen?

This series of mini-fridges are not designed to keep things frozen. These are designed for a positive temperature only and not to freeze the contents loaded inside.

Does the back of a Subcold fridge get very hot?

Thermoelectric units have two sides, so when a DC electric current flows through the device, it moves heat from one side to the other, so that one side gets cooler. Make sure there is at least a 10cm clearance for necessary airflow and circulation. If the back of your mini fridge gets very hot, turn off the unit, and contact Customer Support.

Will my Subcold mini fridge make a lot of noise?

Subcold mini-fridges are not noisy thanks to ongoing advanced technology and our unique cooling system that makes our thermoelectric units quiet, yet powerful and efficient. The fan makes a slight whirring sound and this sound is normal. However, if you hear a very loud sound, turn off the unit, and contact Customer Support.

Are interior shelves removable?

Yes, the shelf and door holders are removable. To remove the shelf, gently Slide it out. To remove the door holder, gently lift it upwards from the slots.
