**** DISPOSAL OF THE PACKAGING

The packaging protects the unit against transport damage. The packaging materials are selected according to the environmental compatibility and disposal-related aspects and  can therefore be recycled.
The return of packaging into the material cycle saves raw material and reduces the waste volume. Dispose of the packaging material no longer  needed at collection points for the “Green Dot” recycling system (in Germany).

DISPOSAL OF THE UNIT

At the end of its service life, this product cannot be disposed of in normal domestic waste. The symbol on the product and in the operating instructions point out to this fact. Reuse the materials according to their marking. With the reuse, recycling or other forms of recycling of old equipment, you make an important contribution to the protection of our environment. Please ask your municipal administration for the disposal point.

REQUIREMENTS ON THE INSTALLATION LOCATION

For safe and fault free operation of the unit, the following requirements of the installation location have to be met:

• The unit has to be placed on a solid, flat, horizontal, and non-slipping surface with a sufficient weight-carrying capacity.
• Make sure that the unit cannot topple over.
• Choose the location in such a way that children cannot reach the supply line of the unit.
• Do not place the appliance on hot surfaces, such as hotplates, or near them.
• Never use the unit in the open, and store in a dry location.
• The unit is not designed for installation in a wall or a built-in cupboard.
• Do not set up the unit in a hot, wet or moist environment.
• The socket has to be easily accessible so that the power cable can be removed easily in case of emergency.

ELECTRICAL CONNECTION

For safe and fault-free operation of the unit, the following requirements have to be met during the electrical connection:

• Before connecting the unit, compare the connecting data (voltage and frequency) on the type plate with those of your energy network. These details must correspond so that no damage occurs to the unit. In case of uncertainty, contact a qualified electrician.
• The socket has to be protected at least by a 10 amps circuit breaker.
• Make sure that the power cable is not damaged and is not laid across hot surfaces or sharp edges.
• The connecting cable must not be stretched tightly.
• The electric safety of the unit is ensured only when it is connected to a socket with protective conductor installed correctly. Operation on a socket without protective conductor is forbidden. If in doubt, let the house installation check by a trained electrician. The manufacturer shall not assume responsibility for damage which has been caused by absent or interrupted protective conductor.

PRIOR TO FIRST USE

Clean all parts as described in the chapter titled “Cleaning and care”.

• Place the coffee bean container on the unit (observe locking mechanism).
• Press the coffee bean container down and turn clockwise (approx. 30 deg.).

SETTING OF DEGREE OF GRINDING

The grain size of the coffee grounds can be varied by means of the different settings of the grinding degree.
Precise data on the grinding degree cannot be given as many different factors play a role, such as type of coffee / bean, room temperature, personal taste, etcetera.

• In general, it can be said that a finer grinding degree is used for Espresso; for filter coffee a medium grinding degree and for French Press a coarser grinding degree is set.  The finer the grinding degree, the longer the grinding process.
• If you use a fine grinding degree, it may happen that the coffee agglutinates. When grinding, slightly tap the lid of the coffee bean container, so that several coffee bean lumps do not block grinding.

GRINDING COFFEE

• Insert the plug into the socket.

• Place the filter holder retainer on the mount.

• Place the filler neck on the outlet.

• Fill the coffee bean container with sufficient coffee beans.

• Set requested grinding degree.

• Push the filter into the filter holder or

• Place the coffee grounds container below the outlet.
  Note: Use whole coffee beans only. Fill the coffee bean container with coffee beans in regular intervals. An evenly distributed weight is important in order to ensure smooth grinding.

• Press the coffee grounds container or filter holder against the button between the filter holder retainer.

• After the requested amount of coffee grounds is reached, pull either the filter holder or the coffee grounds container back.

CLEANING

Old coffee remaining in the unit may lead to oxidation. This affects the taste. The unit should always be in a well-kept condition in order to ensure perfect coffee at all times.
We recommend to clean the unit at least once a week.
Prior to cleaning, remove the power plug.

• Use a soft and moist cloth to clean the outer surfaces of the unit. Use a mild detergent in case of heavy soiling.
• Remove the coffee bean container; hold the grinding ring; press the bean container down and turn counter-clockwise.
• Place the unused beans in an airtight container so keep the flavour.
• Clean the coffee bean container and the coffee grounds container in warm water using a little washing-up liquid.
• Afterwards, dry the containers well.

CLEANING THE GRINDING MECHANISM

• Remove the power plug.

• Remove the coffee bean container as described in the chapter titled “Cleaning”.

• Turn the grinding ring to the right as far as possible.

• Press the “PUSH” button, and continue to the grinding ring to the right.

• When the two arrows point at each other exactly, you can remove the grinding ring together with the upper grinding mechanism. Remove the upper grinding mechanism from the grinding ring.

• Clean the lower and upper grinding mechanism with the brush enclosed.

• After cleaning, first of all place the grinding ring back on to the motor block (arrow pointing to arrow).

• Now place the upper grinding mechanism.

• Turn the grinding ring clockwise to the requested grinding degree

Note: In order to test whether the grinding mechanism has been set in correctly, turn the grinding ring to “coarse”, such as level 20, and try to pull out the grinding mechanism by the metal ring. If the grinding mechanism cannot be removed, it has been installed correctly.

• Place the coffee bean container on the unit.

TIPS

• Precise recommendations for grinding degree settings cannot be provided due to various factors.
• Beans / types of beans react differently (oily, old, freshly ground etcetera).
• The personal taste plays a role as well.
• Choose a finer grinding degree setting for Espresso.
• Choose a medium grinding degree setting for filter coffee.
• Choose a coarse grinding degree setting for French Press.
• Select a coarser grind setting if no coffee powder falls out of the ejector even though the machine is running.
• Room temperature / air humidity have an effect on the coffee beans.
• The tendency for the correct grinding degree setting for Espresso can be seen by the fact that the coffee grounds start to go lumpy. The coffee grounds are not too lumpy when dropping out; smaller to medium-sized lumps are formed which spread again when dropping out. The coffee grounds have a fine feel.
• It is very important to find the right grinding degree for preparing coffee (extraction time). In case of a wrong grinding degree, the coffee cannot be extracted in an ideal  way. It is either under or over extracted.
• However, there is no “perfect grinding degree”. Everyone should find his or her grinding degree according to his or her taste preferences.
• The setting of the grinding degree should also take into consideration the contact pressure and the dosage as well as the roasting degree of the bean used. Some test grinds are necessary here. For this reason the contact pressure and the dosage should be kept constant; the grinding degree should be attuned.
• The finer the grinding degree, the longer the grinder needs.
• It may happen that the grinding degree has to be corrected after some time because the quality, the moisture content and the freshness of the bean depends very much on the surroundings. This can be corrected quickly by trying out and adapting  the grinding degree and/or contact pressure, if the Espresso run into the cup too quickly or too slowly.

2 YEAR WARRANTY

As from the date of purchase we assume manufacturer warranty of twenty-four months for defects which can be traced back to manufacturing and material defect. Your legal warranty claim in conformity with Section 437 ff. of the German Civil Code (BGB) shall remain unaffected by this regulation.
