  • Page 20: Defrost Water

      Defrost water The product generates defrost water during defrosting, which is conducted out into a re- evaporation tray at the back of the product (see Fig. 7). A re-evaporation tube from the cooling system on freezers or an electric heating element placed on the tray for refrigerators (K and M models) will enable the water to be re-evaporated.

      Door closing mechanism The door is equipped with a self-closing system. If the door is opened less than 90, it will close by itself. If the door is opened more than 90, it will stay open. The door can be opened by using the foot pedal. This leaves both hands free when placing foodstuffs the cabinet.

  • Page 22: Door Gaskets

      Door gaskets This chapter deals with the importance of a well-functioning door gasket. Gaskets are an important part of a refrigerator/freezer. Gaskets with reduced functionality, reduces the tightness of the cabinet. Reduced tightness might cause increased humidity, internal icing, an iced up evaporator (leading to reduced refrigeration capacity), and in worst case reduced lifecycle of the cabinet.
