Tips and tricks for electronic refrigerator :

1. The closer to the thermoelectric element inside the cooler, the better cooling effect is.
2. For very cold drinks, 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 refrigerator.
4. For a ready meal, put the meal in a metal dish first, and then cover it with cling film and put on the base of the unit close to the inner wall of the refrigerator.
5. For refrigeration of cosmetic items or medicine, put them in the middle or lower shelf, the closer to thermoelectric cooler, the better cooling effect is.

Temperature reference for refrigeration and freshness

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 a n unheated room would possibly make the items freeze internally.
3. Recommended to keep the room ambient above 18°C and below 25°C for best operation. Ensure ventilation at all times.

APPLICATION
