4. Turn on the light (2).

Let the empty showcase run for at least one hour or until the desired temperature is reached. The food should be inserted after the requested temperature is reached.

After switching the display case starts cooling. The cold air from evaporator is distributed by fans to shelves and display bottom board. There are front and back cold air exhausts on the exhibition board. The warm air is sucked by back condensers fans. It is neccessary not to block the back and side air access exhausts.

The collection, drainage and evaporation of condensate from the evaporator is done automatically. The case is equipped with automatic defrosting, set by the manufacturer (every 6 hours for 30 minutes). The condensed water is automatically drained from the evaporator into an evaporating dish and subsequently evaporated into space.
