6.2 Manual adjustment of the brewing pressure
Machines without option water tank/ direct water connection use (item no. 82044, 82244, 85044, 85244)
You can individually adjust and change the brewing pressure by turning the adjusting screw, choosing a value
between approx. 8.5 and 12 bar.
To adjust the brewing pressure, proceed as follows:
1 Open the cup warmer tray.
2 Place the filter holder with the blind filter into the brew group
3 Operate the group lever and read the pump pressure gauge.
4 Choose the desired brewing pressure by turning the adjusting screw with a coin or a flat screwdriver. You can
reduce the brewing pressure by turning the screw anti-clockwise and increase it by turning it clockwise.
5 Read the pump pressure group to see the adjusted brewing pressure.
6 Now the machine is ready for use again.
Machines with option water tank/ direct water connection use (item no. 82274, 85274)
Important
The brewing pressure of the machine can be adjusted manually without opening the machine through
an adjusting screw at the bottom of the machine.This adjustment must be carried out by expert
specialists.
6.3 Preparing coffee
Use the portafilter with 1 spout and the corresponding filter (1 cup) for the preparation of 1 cup. Use the portafilter
with 2 spouts and the big filter (2 cups) for the preparation of 2 cups. Make sure that the filter is firmly placed in the
portafilter. Fill the finely ground coffee into the filter.
Use 1 level measuring-spoon of coffee for each cup (approx. 7 – 9 g). Do not overfill the measuring-spoon.
Compress the ground coffee with the tamper. Clamp the portafilter firmly into the brew group.
Place the cup under the spout of the portafilter (for the preparation of 2 cups, put 1 cup under each spout).
Now activate the brew lever to start the brewing process. In general, the brewing time should be around 23 to 25
seconds. The volume for a single espresso is circa 25 to 30 ml. Place the brew lever back into the original position
once the desired volume is reached.
The remaining pressure/water will be discharged into the drip tray through the lower part of the infusion cylinder.
The pump pressure can be read on the pump pressure gauge. If the coffee powder is too coarse, a brewing pressure
over 9 bars is not possible.
Advice: After the brewing process, the gauge still indicates a certain pressure. Only when preparing another cup of
coffee will the build-up of pressure be visible again.
Caution!
If the group lever is not moved into the lower position properly, hot water and grounds will squirt out of
the brew group while taking out the filter holder. This may cause injuries.
• Only freshly ground coffee allows for an optimal coffee result. Therefore, use a professional
coffee grinder. In our assortment you will find several professional and compact coffee grinders.
• We recommend to use a stainless steel tamper with a diameter of 58 mm for optimum tamping.
