Coffee maker with vacuum jug
∙ For technical reasons the screw cap does
not close hermetically. Therefore always
hold the jug in an upright position.
∙ Keeping the coffee hot: A vacuum
jug accumulates heat energy. Therefore
the jug should preferably be fi lled to its
maximum capacity. If it is only partly
fi lled, the temperature will not be held
as effi ciently. If you rinse out the jug with
hot water before use, the coffee will be kept
warm for a longer time.
Vacuum jug with glass fl ask
The glass fl ask of the jug is made of high
quality double-walled glass.
Any marks inside the jug looking like bubbles
or scratches do not affect its use nor its
ability to keep the temperature.
To prevent damage to the glass fl ask:
∙ Avoid shocks and great differences in
temperature.
∙ Do not stir in the jug, 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 cut the glass (similar to a
glass-cutter).
∙ Do not wash in a dishwasher.
∙ Do not use in a microwave oven.
For better insulation, there is a vacuum in-
between the two walls.
In case the glass is damaged for one or
the other reason as mentioned above,
there is a risk that the glass fl ask
implodes. This might happen quite some
time after the glass fl ask has actually been
damaged.
Therefore do not drink out of the jug and do
not put your hand into it.
∙ Always close the jug with its screw cap.
∙ The coffee can be poured out easily by
half a turn of the cap, without removing
the cap. For coffee maker with drip-
through lid, simply press the lever down.
∙ Do not leave the vacuum jug unattended
near where children may reach it.
Descaling
∙ To keep the coffee maker in excellent
working order, we recommend that you
descale the appliance at regular intervals.
∙ Descaling is required when the fi ltering
process takes longer than normal, or if the
appliance becomes noisy during operation.
∙ An excessive build-up of lime deposits is
very diffi cult 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
operations.
∙ Any warranty claim will be null and
void if the appliance malfunctions
because of insuffi cient descaling.
∙ We recommend using vinegar for descaling.
∙ Mix 80 ml of vinegar essence with the
indicated maximum amount of cold water.
∙ Pour this mixture into the water reservoir.
Place a paper fi lter into the fi lter holder
(without ground coffee) and operate the
appliance as described in section To
prepare fi lter coffee. Repeat the descaling
process if necessary. Ventilate the room
during the descaling process and do not
breathe in the vinegar vapours.
∙ To cleanse the appliance after descaling,
operate it a further three times with cold
fresh water only (without using ground
