Heat-retaining carafe
∙ For technical reasons, the screw
cap does not make a complete seal.
Therefore, always hold the carafe in an
upright position.
∙ Keeping the coffee hot: a heat-
retaining carafe accumulates heat
energy, and the carafe is therefore
better filled to its maximum capacity. If
it is only partly filled, the temperature
will not be maintained as efficiently.
If you rinse out the carafe with hot water
before use, the coffee will be kept warm
for a longer.
∙ T he glass flask of the heat-retaining
carafe is made of high-quality double-
walled glass.
∙ Any streaks or bubble marks inside the
carafe looking like bubbles or scratches
do not affect its functional use nor its
heat-retaining ability.
∙ For better insulation, there is a vacuum
between the two walls.
∙ In case the glass is damaged for one
or the other reason as mentioned
below, there is a risk that the glass
carafe implodes because of the
vacuum. This might happen quite some
time after the glass carafe has actually
been damaged, so that a connection to
the actual cause of the damage is not
obvious.
∙ Therefore, do not drink out of the carafe
and do not put your hand into it.
To prevent damage to the glass flask:
∙ Avoid shocks and large differences in
temperature.
∙ Do not stir liquid inside the carafe with
metal objects or other hard implements,
for example with a metal spoon.
∙ Do not use hard brushes or abrasive
cleaning agents.
∙ Do not wipe the inside with a cloth. Dust
particles may damage the glass (in the
same way as a glass-cutter).
∙ Do not put in a dishwasher.
∙ Do not use in a microwave oven.
Descaling
∙ Depending on the water quality (lime
content) in your area as well as the
frequency of use, all thermal household
appliances using hot water need
descaling (i.e. removal of lime deposits)
on a regular basis to warrant proper
functioning.
∙ A lengthening of the brewing time,
residual water remaining in the container
or increased noise during brewing
indicate that descaling of the coffee
maker has become necessary.
∙ An excessive build-up of lime deposits
is very difficult to remove, even when
strong descaling agents are used. It may
also cause the brewing system to leak.
To avoid damage caused by the build-up
of deposits, descale the appliance after
thirty to forty brewing cycles.
∙ Any warranty claim will be null and
void if the appliance malfunctions
because of insufficient descaling.
∙ We recommend using vinegar for
descaling.
