• Press the hand lever down again to finish the process.

ESPRESSO PREPARATION

IMPORTANT!
See chapter preparation in order to warm up the group handle, system and cups. Insert the filter insert for one cup or two cups. After that, start preparing espresso.

• After that, dry the group handle well.
• Grind the desired amount of coffee grounds into the group handle.
• Firmly press on the coffee grounds using the enclosed tamper. The tamper should rest evenly and not crookedly on the ground coffees when it is pressed down. This ensures even distribution and brewing over the entire surface.
• Clamp in the group handle.
• Place either one or two cups underneath the outlet.
• Press for a single espresso or  for a double espresso/two espressi or use the hand lever for manual preparation.
• The display shows the current processing time. Ideally, the processing time should be approx. 20-30 seconds. While brewing, the brewing pressure can be changed with “+” or “-”, from P7 to P1.

• Remove the group handle and tap out the coffee grounds in a used coffee tray.

PRESSURE GAUGE

UNDER-EXTRACTION
In case of under-extraction you will get a very thin, flat and underdeveloped coffee. The coffee flows very quickly into the cup. In this case, too little components have been dissolved out. The coffee is very light, the cream very thin, not available or the cream is very light with large bubbles.

• Brewing pressure smaller than 7 to 8 bar
• The coffee flows very quickly into the cup.
• The coffee tastes sour or flat

Possible reasons for an under-extraction

Grinding level too coarse (falls out of the outlet quite quickly, the cof- fee grounds feel rather coarse-gained when rubbing them between your fingers).| Grind finer, slowly approach the optimum grinding level.
Too little coffee grounds.| Use more ground grounds, note the maximum filling quantity, the grind may also need to be adjusted.
Channeling: Pressure uneven| The tamper should rest evenly and not crookedly on the compressed coffee grounds. Otherwise, channels may form in the coffee and the hot water will flow through the coffee too quickly.
Beans not fresh or coffee grounds not fresh (possibly pre-ground too long).| Ideally, store the beans in the coffee packaging closed again. Oth- erwise, light and oxygen will age the coffee. Only remove as much coffee as you need in a short time.
Beans have been roasted too light.| Lighter beans have a slightly different brewing behaviour than dark beans and are usually brewed at lower pressure. A delicious espres- so with different flavours can also be prepared by adjusting the quan- tity and grinding level. However, this can only be addressed briefly in these instructions.
Brewing temperature too low.| Adjust the brewing temperature in the menu.

OPTIMAL EXTRACTION
In case of optimal extraction, the espresso flows evenly, slowly and creamily “like honey” out of the outlet into the cup. The cream is dense and dark brown to golden brown.

• Brewing pressure from 7-8 bar up to 12-13 bar
• Contact pressure approx. 15 kg
• Coffee grounds evenly distributed in the group handle
• Optimal grinding level, not too fine, not too coarse
• Fresh beans or freshly ground coffee grounds
• Optimal water temperature, not too cold, not too hot

OVER-EXTRACTION
In case of over-extraction, too many bitter substances are dissolved out of the coffee. Preparation takes a long time, the coffee flows slowly and drop by drop into the cup. The coffee is very dark or the cream is dark brown to reddish and has an unpleasant and bitter or even burnt taste. The outline on the cream is very uneven, with lighter spots being found between darker areas.

• Brewing pressure over 13 bar
• Coffee runs slowly (brewing time well over 30 seconds) and flows drop by drop into the cup
• The coffee tastes bitter and burnt

Possible reasons for an over-extraction

Grinding level too fine (falls out of the outlet rather slowly, the coffee grounds sometimes feel like powder when you rub it between your fingers).| Grind coarser, slowly approach the optimum grinding level.
Too much coffee grounds.| Use less coffee grounds, the grinding level may also need to be ad- justed.
Beans roasted too dark.| This rarely happens with bought beans. For home- roasted beans, fin- ish the roasting process earlier.
Prior to preparation, coffee grounds clamped too long in the brewing unit.| The coffee grounds can change the flavour due to the temperatures. As a result, the coffee tastes burnt with otherwise optimal extraction. After clamping, the brewing process should be started immediately.
Brewing temperature too high.| Adjust the brewing temperature in the menu.

SETTING THE WATER QUANTITY FOR
You can change the water quantity for   cups as you wish. The LCD display shows the processing time, but the water  quantity is determined by a flow sensor.

• Switch on the unit. The unit is heating up.
• If “GRAEF” appears on the display, the unit is ready for operation.
• Insert the desired filter insert.
• Grind the desired amount of coffee grounds into the group handle.
• Firmly press on the coffee grounds using the enclosed tamper. The distance between the upper edge and the ground coffee should be approx. 3 mm.
• Clamp in the group handle.
• Place one or two cups underneath the outlet.
• Press either the button for 3 seconds.
• The preparation starts.
• After the desired quantity, press the button again.
• The water quantity is saved for the selected cup.

PRESSURE PROFILE SETTING
With this group handle espresso machine, you can get the best out of your coffee thanks to the right pressure profiles.

RECOMMENDATION
Firstly, use the factory-set profile before creating print profiles. Prepare the best possible espresso (grinding level, contact pressure and grind-ing quantity must be correct). A well-adjusted coffee grinder is the ideal basis for a good espresso. You can only create your own pressure profile to improve the flavour/extraction time once all parameters have been coordinated.

AUTOMATIC SWITCHING OFF
To save energy, the unit turns off after approximately 30 minutes when not in use (Regulation of the EU Commission).

MAKING MILK FROTH

• Switch on the unit. The unit is heating up.
• If “GRAEF” appears on the display, the unit is ready for operation.
• Fill half of the supplied milk jug with milk. Make sure that it is at refrigerator temperature.
• Direct the steam lance toward the drip tray.
• Turn the rotary knob so that it is open and allow the condensation water to escape.
• Turn the rotary knob so that it is closed again.
• Turn the steam lance outwards and place the steam lance in the milk jug.
• Check to see that the steam nozzle is just below the surface of the milk.
• Turn the rotary knob so that it is open.
• You will have achieved the right position if you can hear kind of a “sip noise”.
• This might suspend for a short time, because the surface of the milk is moving. You are in the draw phase.
• Slowly lower the milk jug as soon as the level rises.
• Once the volume has increased as desired, enter the roll phase.
• Guide the milk jug upwards so that the nozzle is completely immersed in the milk.
• Now hold the milk jug as still as possible.
• Place one hand flat against the milk jug.
• The milk should swirl without drawing in any more air.
• If air is drawn in again, change the position of the steam nozzle slightly.
• The milk foam has reached the right temperature when the side of the milk jug becomes too hot to hold.
• Turn the rotary knob so that it is closed.

IMPORTANT!
Remove the steam lance from the milk only after turning the rotary knob so that it is closed.

• Now remove the steam lance from the milk.
• After making the milk froth, hit the milk jug briefly onto the table top in order to remove the last coarse air bubbles. Swivelling is also helpful to distribute the froth evenly.
• Clean the steam lance immediately afterwards to avoid milk incrustations.
• A short burst of steam is enough to blow the milk residue out of the nozzle. Clean the outside of the nozzle with a damp cloth. Caution, the steam lance gets hot.

IMPORTANT!
To practise it, you can use the following method:

• Pour cold water into the milk jug.
• Add a drop of detergent.
• Froth it up as described above.
• If you carry out the frothing process correctly, the mixture will look like real milk foam. Please do not drink this mixture!!

HOT WATER WITHDRAWAL

• Switch on the unit. The unit is heating up.
• If “GRAEF” appears on the display, the unit is ready for operation.
• Put one cup under the hot-waterlance.
• Turn the rotary knob so that it is open.
• The water flows into the cup.
• When the process is completed, close the rotary knob again.

DESCALING REMINDER

The factory setting for the descaling function recall is set to 25 L. After 25 litres have been used, “KALK” flashes on the display. You can continue to use the unit as usual, but “KALK” will continue to appear on the display. Only after a complete decalcification of the three circuits, the “KALK” display goes off on the display (for this, see the “Descaling” chapter). The number of liters can be changed according to the use and hardness of your water.

• 12 L = (In hard water areas with more than 15°dH)
• 25 L = (In mild water areas with 7,3°dH up to 14°dH)
• 50 L = (n soft water areas with up to max. 7,3°dH)

You can ask for your exact water hardness at the local waterworks. To find out how to change the number of litres, see page 33 under “DESCALING REMINDER”.

DESCALING
Regularly perform a decalcification, at the latest when “Kalk” appears on the display. All circuits must be descaled. We recommend to use Graef descaling tablets. You can obtain them in our online shop at www.graef.de under item No. 145618 or from your specialist dealer.

• Insert a water filter cartridge into the water tank. We recommend that you replace it after every descaling. You can obtain replacement water filter cartridges in our online shop at www.graef.de under item No. 146242 or from your specialist dealer.

IMPORTANT!
The water filter cartridge does not provide complete protection against calcification – regular replacement of the cartridge does not mean that you can forego descaling.

RINSE AFTER DECALCIFICATION
To flush the remaining mixture out of the pipes, fill fresh water into the water tank. Then carry out the following flushing processes one after the other:

1. Allow water to run through the brewing unit for 20 seconds (empty draw without coffee grounds).
2. Open the steam valve for 20 seconds.
3. Open the hot water valve for 20 seconds.
