Frequently Asked Questions - CM 820 GRAEF

How to adjust the fineness of grind on the Graef CM 820?

Turn the grinding crown to the desired number of positions. There are 35 levels, from finest (low number) to coarsest (high number). For espresso, choose a fine setting; for filter coffee, a medium setting; for a pressure coffee maker, a coarse setting.

How to use the direct grinding function into the portafilter?

Install the appropriate portafilter holder (60 or 70 mm). Open the extraction outlet of the bean container. Set the grind degree. Place the portafilter between the holders and set the switch to AUTO. Press the portafilter against the switch: grinding starts automatically. Remove the portafilter once filled, grinding stops.

How to clean the grinder of the coffee grinder?

Unplug the appliance. Remove the bean container. Turn the grinding crown to the right until it stops, press the PUSH button and continue turning to unlock. Remove the crown with the upper burr. Clean the lower and upper burrs with the included brush. Reassemble by aligning the arrows, then turn the crown to the desired degree.

Can I grind already ground coffee?

No, the Graef CM 820 is designed exclusively for grinding whole coffee beans. Do not put ground coffee in the container, as this could damage the appliance.

PREFACE

Dear Customer,

You have made a good choice by buying this coffee grinder. You have purchased a recognised quality product.

Thank you very much for buying our product. We wish you a lot pleasure with your new Graef coffee grinder.

UNPACKING

Proceed as follows to unpack the unit:

• Remove the unit from the box.
• Remove the packaging parts.
• Remove any stickers on the unit (do not remove the typeplate).

REQUIREMENTS ON THE INSTALLATION LOCATION

For safe and faultfree 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, non-slipping and heat-resistant surface with a sufficient weight-carrying capacity.
• Choose the location in such a way that children cannot reach the unit.
• The unit is not intended for installation in a wall or a built-in cupboard.
• Do not set up the unit in a hot, wet or moist environment.

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.

Note:

• The finer the grinding degree, the longer the grinding process.
• If you use a very fine grinding degree, it may happen that the coffee agglutina-

tes. If several coffee bean lumps block the grinding mechanism, tap the coffee bean container.

GRINDING COFFEE WITH PERMANENT FUNCTIONALITY

• Insert the plug into the socket.
• Fill the coffee bean container with coffee beans.

Note: Use whole coffee beans only.

• Open the outlet of the coffee bean container by using the sliding closure.
• Set requested grinding degree.
• Place the coffee grounds container below the outlet.
• Set the switch to "ON". The grinding process will start automatically.
• After completing the grinding process, set the switch to "OFF".

GRINDING COFFEE DIRECTLY INTO THE FILTER HOLDER

- Use the large or the small filter holder retainer as requested.

- Open the outlet of the coffee bean container by using the sliding closure.

- Set requested grinding degree.

- Hold the filter holder between the filter holder retainer.

- Set the switch to "AUTO".

- Press the filter holder against the contact switch between the filter holder retainer. The grinding process will start automatically.

- As soon as the filter holder is sufficiently filled, pull it back. The grinding process will stop automatically.

CLEANING

Old coffee remaining in the unit may lead to oxidation. This affects the result of the preparation; unpleasant and unpalatable taste may develop. The unit should always be in a well-kept condition in order to ensure perfect Espresso at all times.

Depending on use, clean the unit at least once a week.

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

Note: In order to test whether the grinding mechanism has been set in correctly, turn the grinding ring to “coarse”, such as level 35, 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.

FINE ADJUSTMENT OF THE UPPER GRINDING MECHANISM

By means of the fine adjustment of the upper grinding mechanism, you can set the grinding degree to coarser or finer.

Proceed as follows:

• Remove the upper grinding mechanism.
• Use a screwdriver to remove the small screws.

- Turn the grinding mechanism one stop to the right (coarser) or left (finer).

Note: Set the grinding mechanism two to three stops to the right or left maximum at first.

• Screw the screws back in again.
• Place the upper grinding mechanism back in again.

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.

→ 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.
