Built In Thermal Insulation Foam Layer Although the ice maker cannot keep the ice frozen all the time, this foam layer can reduce the speed of ice melting. It can keep the ice for 3-5 hours (depending on the ambient temperature). Blue Light In order to give you a better use and visual experience, we have designed a blue light in the ice maker. When it lights up, the ice will look so fresh and clean. Gravity Drainage (Drain Required) This is something you should pay attention to before purchase. After the ice melts, this ice maker drains the melted water by gravity. We recommend that you use a condensate pump or place the ice maker above the ground so that the water can drain smoothly. Ice Full & Water Shortage Reminder When the ice maker is full of ice or short of water, the ice maker will light uo the full ice indicator or the water shortage indicator. It makes it easier for you to know the working conditions of the ice maker. 24 Hours ON/OFF Timer If you need ice at 9:00 in the morning, you can set the automatic startup timing at night. Let the ice maker start making ice at 6:00 a.m. or earlier. This will not cause waste of water. Compact Size The size of this commercial ice maker is 16.53(W) × 14.96(D) × 29.82(H) inches.
