DESCALING REMINDER

The factory setting for the descending function recall is set to 25 L. After the consumption of descal setting, a red ring light up. Only after a complete decalcification the light goes off.

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 5^ )

25 L = (In mild water areas with 7,3° dH up to 14° dH)

50L = (n soft water areas with up to max. 7,3^)

You can ask for your exact water hardness at the local waterworks.

PRESSURE GAUGE

Under-extraction:

In case of under-extraction you will get a very thin, flat and underdeveloped coffee. 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 up to 9 bar
• Grinding degree too coarse (falls rather quickly out of the outlet, with only a few lumps or small balls to be seen. The coffee grounds feel rather coarse-gained when rubbing them between your fingers)
  Dosage is too low
• Coffee grounds distributed too unevenly in the group handle
• Contact pressure too little
  Pressure uneven
  Water temperature too low
• Coffee beans not fresh
• Coffee grounds not fresh (possibly pre-ground too long)

Optimal Range

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 between 9 and 10 bar
• Contact pressure approx. 15kg
• Coffee grounds evenly distributed in the group handle
• Optimal grinding level, not too fine, not too coarse
• Optimal water temperature, not too cold, not too hot
  Beans are fresh
• Coffee grounds freshly ground

Over-extraction:

In case of over-extraction, too many bitter substances are dissolved out of the coffee. 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 10 bar
  Grinding level too fine (falls rather slowly out of the outlet, partly larger chunks or lumps).
  Dosage too high
• Contact pressure too strong
  Water temperature too high
• Prior to preparation, coffee grounds clamped too long in the brewing unit

PRIOR TO FIRST USE

Prior to first use, clean the group handle (not the unit) and the water tank under running water so that potential production residues are removed.

INITIAL OPERATION

CAUTION

Observe the following safety instructions to prevent hazards and material damage:

During use, the surfaces become hot!
- While water is runing through the machine, never remove the group handle filled with coffee grounds, because it is under pressure.
- Before preparing espresso, check to see that the group handle is tightened firmly.
- Do not misuse the espresso machine other than it's intended use in order to avoid potential injury.
- After switching on, the appliance steams. This is not a fault on the device.

VENTING

Note: The device must be vented before initial start-up or after prolonged non-use.

• Insert the plug into the socket.

• Fill the water tank with fresh water.

• Switch the unit on ( )

• Units heats up.
• The unit is ready for operation when all buttons are lighted up.
• Put one cup or one glass under the hot-water / steam wand.
• Rotate the knob on.
• Let the air escape until a constant water jet runs through.
• Rotate the knob off.

PREPARATION

Note: After switching the unit back on again, carry out an empty withdrawal (without coffee grounds) as described below in order to bring the system to temperature.

• Fill fresh water into the water tank. 2.5 litres at the maximum.
• Insert the desired filter insert.

- Press the button.
- Let the cup run half full, to bring the system to desired temperature.
- Then press the button to end the procedure.

ESPRESSO PREPARATION

IMPORTANT!

• Make sure that there is always enough water in the tank. If too little water or no water enters the tank, the small red lamp next to the water level indicator flashes.
• Make sure the water tank is always used correctly.

SINGLE ESPRESSO

Note: See under preparation in order to warm up the group handle, system and cup. After that, start preparing espresso. Insert the filter insert for 1 cup.

• Dry the group handle after preparation.
• Grind the coffee into the group handle (until the group handle is full).

• Firmly press on the coffee grounds using the enclosed tamper.

• The distance between the upper edge and the coffee grounds should be approx. 3mm

• Wipe the excess coffee from the edge and tighten the group handle.
  Put a cup below the outlet.
• Press the button.
  After finishing the process, remove the group handle.
• Tap the coffee grinder in a grounds container (not included).

DOUBLE ESPRESSO

Note: See under preparation in order to warm up the group handle, system and cup. After that, start preparing espresso. Insert the filter insert for 2 cups.

• Dry the group handle after preparation.
• Grind the coffee into the group handle (until the group handle is full).
• Firmly press on the coffee grounds using the enclosed tamper.

• Wipe the excess coffee from the edge and tighten the group handle.
  Put a cup below the outlet.
  Press the cup.
  After finishing the process, remove the group handle.

Tap the coffee grinder in a grounds container (not included).

AUTOMATIC SWITCHING OFF

To save energy, the device turns off after approximately 30 minutes when not in use. (Regulation of the EU commission).

MAKING MILK FROTH

If the unit is switched off, switch it back on again

• Units heats up.
• Pour cold milk into the milk jug.
• Hold the hot-water / steam wand toward the drain cover.
• Press the 3 button. It is flashing, with the system heating up.
• If the 3 button illuminates, the system is ready for operation.
• Rotate the dial and allow the condensation water to escape.
  After the condensation water has leaked out, turn the knob again.
• Swivel the steam distributor outward.
• Turn on the control knob and hold the milk jug at a slight angle.
• Once the milk level is increasing, lower the milk jug.
  After finishing the process, turn off the control knob again.
• Wipe the steam plant with a damp cloth after a sufficient allowed time for cooling. This can be very hot, right after use.
• Press the 3 button again.

WARNING

• To froth milk, only use the attached milk jug or a larger vessel. Do not use a cup. Excessive foaming milk may lead to burns.
• Never direct the steam plant to yourself or others. There is a risk of burning.

Please note:

If the milk is heated up to more than 70^ , the foam will simply collapse and the drink will later taste too sweet or even of burned milk.

Tips for making milk froth

The phases "steep" and "roll"

• First the "steep phase": in order to fold in the air, put the steam distributor very closely below the milk surface.
• 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.
  Now it is for the "roll phase".
• As soon as the volume of the milk increases, slide the steam distributor into the milk.
• When the pot becomes hot, turn off the control knob.
• After making the milk froth, hit the pot briefly onto the table top in order to remove the last coarse air bubbles.
• Swivelling is also helpful to distribute the froth evenly.
• Immediately after finishing the process, clean the steam distributor using a damp cloth. However, allow the tube to cool down for a little, as this becomes hot.
• Clean the steam distributor also using a short jet of steam so that the milk remnants are blown out of the steam distributor.

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 froth it correctly, the mixture will look like real milk froth.
• Please do not drink this mixture!

HOT WATER WITHDRAWAL

If the unit is switched off, switch it back on again

The unit is heating up.
The unit is ready for operation.
- Put one cup under the hot-water distributor.
- Turn on the control knob.
Water is flowing into the cup.
After finishing the process, turn off the control knob again.
