4Grinder Aroma+:
Precision grinder, 5grinding degrees
5Bean container:
Capacity 125 g
6Monitoring:
6.1 Aroma preservation lid:
With a UV protection and silicon seal
Checked by a micro switch (CLOSE COVER)
6.2 Powder funnel surveillance:
Checked by a REED/Magnet (FILL POWDER)
Place 1 level measuring spoon of ground coffee into the filler funnel (due to overfilling)
When not drawing off a product then the powder will be wetted and pushed down into the grounds
container after 1 min.
Timeout of 1.5 sec. until powder draw off is enabled
6.3 Water tank:
Capacity 1.1 liters
Monitored with a floater (FILL WATER TANK)
6.4 Grounds container:
Tray of the residual water container is checked by a micro switch
(EMPTY TRAY / EMPTY GROUNDS)
After max. 10 portions (flavour MILD), the message (EMPTY GROUNDS) shows up
With milk products (Cappuccino, Latte Macchiato), the message shows up after max. 5 draw offs.
Reason: There is no residual water monitoring and if one would rinse into the container after each
milk product, the residual water container would overflow after 10 draw offs.
