The heating plate will maintain the temperature in the carafe for 2 hours after which the
machine shuts off automatically. This is for safety and convenience. The auto-off time
can be adjusted to 1, 2 or 3 hours. See page 11 – Programming the unit.
For best results brew only as much coffee as you will drink within 30-60 minutes.

Pause and Serve feature:

You can remove the carafe during the brew cycles to pour an early cup. Keep in mind
that this will change the taste you would normally get from a full pot in a complete
cycle.
Be sure to replace the carafe quickly (less than 20 seconds) to avoid overflow during
the brew cycle.
For models with thermal carafe : to ensure maximum heat retention, rinse the
thermal carafe with hot water before use, and close the lid by turning clockwise.

This function controls how long the heating plate will continue before automatically
turning off. For best results we recommend brewing only as much coffee as you will
consume in 30-60 minutes. Taste is affected the longer the coffee is allowed to sit on
the heating plate.

This function is designed specifically for small batches, normally less than 6 cups,
where brew cycles become too short to properly extract the coffee taste from the coffee
ground.
To activate press the Aroma button (q), then press On.

Note : this function cannot be changed once the brew cycle has started.

The function can also be used for full pots but will cause more of the bitter flavors to be
extracted in that case. Krups recommends only using Aroma Control for small batches
less than 6 cups.

• DuoFilter Water Filtration: active vegetable based double acting anti-chlorine and

anti-scale filter. The anti-chlorine action of the filter brings out the most delicate
flavors of the coffee. The anti-scale action allows for longer periods between
descaling.

Note: there is a rotary indicator on the top of the water filter holder. This indicates
when the DuoFilter should be changed. Place the index mark next to the month the
filter should be changed, referring to the chart below.

Example: if you replace the DuoFilter in January (1) you should set the indicator to
March (3) or May (5), depending on the hardness of your local water supply: position
the number 3 or 5 opposite the index mark.

Important:

• The DuoFilter must only be used with water.

• The coffee machine still functions if the water filter is not in place.

• If the coffee machine has not been used for more than one month, rinse the

DuoFilter under running water.

• It is recommended not to leave the DuoFilter in place for more than 5 months.

• Your appliance is designed for use with the carafe type (glass or thermal) it was

purchased with. Do not use thermal carafes on coffeemakers purchased with a
glass carafe and vice versa.

Turn off the coffee machine and remove the plug from the outlet. Do not clean the
coffee machine when it is hot. Never immerse the coffee machine in water or put it
under running water.

• Clean the body of the coffee machine with a damp cloth or sponge.

• Open the top lid (a), remove the paper or permanent filter. The filter holder (f) can

be washed in warm soapy water and rinsed thoroughly, or cleaned in the upper rack
of a dishwasher.

• We recommend washing carafes by hand with a mild detergent.

• Do not use scouring agents or harsh cleansers on any part of the coffee machine.

Descaling is necessary to keep your coffee machine running efficiently. The frequency
of descaling depends on the hardness of your water and how often you use the coffee
machine.
If you notice the brew cycle has slowed it is generally time to descale the machine.
See the chart below:

Before descaling, remove the filter holder (f).

• You may use either the Krups descaling solution diluted in 16 ounces of water or

8 ounces of white vinegar.

• Pour the solution or vinegar into the water reservoir and start the coffee machine

(without coffee).

• Allow half the liquid to run into the carafe, then switch off and let stand for 1 hour.

• Restart the coffee machine to complete the cycle.

• Rinse the coffee machine by running it through 2 full cycles with water only.

Choose your beans wisely. It is best to use premium whole beans from a trusted brand
or roaster. Arabica beans provide the best flavors and have less caffeine, while
Robusta beans are easier to grow and less expensive, they have less flavor and higher
caffeine content. Robusta beans are sometimes used in blends to add a particular
bitterness to the brew.
Beans can be roasted very lightly to provide a smooth aromatic taste or roasted dark to
provide stronger flavors, and anywhere in between.
A good roaster will be able to describe the flavors that the beans will impart to your
brewed coffee.

Note: experiment with different beans and different roasts to identify one or several
that suit your tastes.

The amount of ground coffee must be carefully measured against the volume of water
for each brew cycle. It is important to use enough coffee to avoid over extraction. A
small amount of coffee would be overwhelmed by a large volume of hot water. The
carafe measures “cups” as 5 oz each. Maximum capacity is slightly more than 50 oz
total water volume before brewing. The volume of brewed coffee will be slightly less
because the ground coffee will absorb a certain amount.

Krups recommends using 7 grams of ground coffee per 5 oz cup of water. 7 grams can
be measured in one rounded tablespoon.
If the resulting brew seems too strong you can adjust by using slightly less ground
coffee. If you prefer a much lighter taste it is best to brew at the recommended ratio
and dilute the resulting brew with a measure of hot water. This allows the best flavor to
be extracted from the beans while avoiding over extraction of too small an amount of
ground coffee.

The water is a critical factor in the taste of your brewed coffee. Filtered water is
normally the best choice to help avoid the minerals and chlorine that can be found in
municipal water systems. However if your water tastes good then it should be good for
your coffee.
Never pour milk, prepared coffee, tea, etc. into a water tank.

The method of grinding and the level of fineness of the grind have a significant impact
on the resulting taste of the brewed coffee. Ideally you should grind fresh roasted
whole beans just before brewing. Be aware that this machine is set to brew the most
common grinds found on store shelves. Typically pre-ground coffees are of a similar
size, medium-coarse. A very fine grind will produce much stronger flavors but risks
becoming extracted during the brew cycle producing a more bitter taste. You can learn
more about coffee grinding and about Krups range of grinders at our website
www.krupsusa.com.

Accessories can be purchased at many retail stores, and though Krups website.
