like bubbles or scratches do not affect
its functional use nor its heat-retaining
ability.
∙ In case the glass is damaged for one
or the other reason as mentioned
below, there is a risk that the carafe
implodes. This might happen quite
some time after the carafe has actually
been damaged.
∙ Therefore do not drink out of the carafe
and do not put your hand into it.
To prevent damage to the carafe:
∙ Avoid shocks and great differences in
temperature.
∙ Do not use any metal or other hard
objects (eg a metal spoon) to stir in the
carafe.
∙ Do not use hard brushes or abrasive
cleaning agents.
∙ Do not wipe the inside with a cloth. Dust
particles may cut the glass (similar to a
glass-cutter).
∙ Do not wash 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.
∙ Any warranty claim will be null and
void if the appliance malfunctions
because of insufficient descaling.
∙ 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. We therefore strongly recommend
descaling the appliance after each thirty
to forty brewing cycles:
∙ For descaling, a vinegar solution may
be used.
∙ Mix 80 ml of vinegar essence with the
indicated maximum amount of cold
water.
∙ Pour the descaling solution into the
water container, insert a paper filter
into the filter holder without adding
any ground coffee as described in
section Making coffee, and let the
appliance run through one filtration
cycle. Repeat the procedure if
necessary. During descaling, ensure
sufficient ventilation and do not inhale
any vinegar vapours.
∙ To clean the appliance after descaling,
let it run through 2-3 filtration cycles
using clean water only.
∙ Do not pour descalers down enamel
sinks.
