Requirements for the installation location
For safe and awless operation of the
appliance, the place of location must meet
these prerequisites:
 The appliance must be set up on a rm, at,
level, non-slip and heat resistant base that
has sufcient load bearing capacity.
 Select the place of location so that children

in a wall or a built-in cupboard.
 Do not set up the appliance in a hot, wet or

Operating and speed settings
 Maximum operating time is 4 minutes. After
these 4 minutes please let the appliance cool
down to room temperature and start again.
Grind setting
You can inuence the composition of the coffee
with various grind settings.
The wide range of grind settings allows you to
make a precise adjustment.
Notice: If you use a ne grind level, it is possible
that the coffee grounds clump together. During
grinding, slightly knock on the coffee bean
container cover so that any possible coffee
bean clumps do not block the grinding.
 Accurate information on the grind setting can
not be made, since many factors such as type
of coffee / bean, room temperature, personal
taste, etc. play a role.
 In general it takes a ner grind for espresso,
a medium grind for drip coffee and a coarser
grind for French press.
