Valid from: 08/2005 Technical changes reserved Page 6

7. Operating description

Drop-in refrigerated well, ventilated

The goods being presented are cooled in drop-in wells with ventilation by means of a directed cold air haze.

This air haze is moved by means of ventilators which suck the air from the goods area through a return air duct (1). The air then enters the evaporator below the goods display panel (2), circulating evenly. At the same time it is cooled down and blown into the goods area through an incoming air duct (3). The airflow takes place via an angled ventilation plate (4). By exactly determining the components very even air distribution is obtained.

This functionality can only be guaranteed if the incoming and return air ducts are kept clear and the cold air haze is not impaired.
