Page 17: Sc (Self Clean) Automatic
SC (Self Clean) Automatic During the production of steam, the concentration of minerals inside the steam generator will increase over time. These minerals settle on the heating elements and heat exchanger as well as the interior steam generator walls. In order to reduce this effect the steam generator will be pumped off and flushed regularly depending on the duration of steam production. -

Page 22: Humidity Control Scc_We
Humidity control SCC_WE In order to measure the humidity inside the interior cabinet the following pysical principle is used: When the fan wheel is turning, the rear fins create a differential pressure on pressure sensor p1 via the connecting hoses (inner and outer connection). The pressure sensor P1 is supplied with 12V DC. - Page 23 Humidity control SCC_WE If the measured humidity value is too high, the clima valve Y5 will be activated and the closing disk will be lifted. The negative pressure behind the fan wheel will cause dry air from the kitchen be sucked into the cabinet.

Page 36: Cds
1.Basics During steam production the concentration of minerals in water of the steam generator increases. These minerals deposit in the steam generator and build up scale. The build up of scale is influenced by the local water hardness and the individual usage of the unit. -
Page 37: Carecontrol
CareControl The condition of the indication depends on: a: the use of the unit b: the cleaning behaviour of the customer c: the degree of scale in the steam generator (see information CDS). Display Care 1: very good care - only one green bar visible. 2: medium care - yellow bars are visible 3: neglected care - red bars are visible The request for Clean+Care has been neglected several times. -
