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 filter holder with 1 spout and the corresponding filter (1 cup) for the preparation
of 1 cup. Use the filter holder with 2 spouts and the big filter (2 cups) for the
preparation of 2 cups. Make sure that the filter is firmly locked into the filter holder.
Fill the finely ground coffee into the filter.
Use
1 level measuring-spoon
of coffee for each cup (approx. 7 g).
Do not overfill the measuring-spoon, as shown in the figure on the right!
Compress the ground coffee with the tamper. Clamp the filter holder firmly
into the brew group.
Place the cup under the spout of the filter holder (for the preparation of 2 cups, put 1 cup under each spout).
Move the group lever into the upper position. When the cup is filled, move the group lever into the lower position.
The remaining pressure/water will be discharged into the drip tray by 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 bar is not possible.
Advice:
After the brewing process, the gauge still indicates a certain pressure. Only when preparing another cup of
coffee the buildup of pressure is 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.
6.4 Dispensing of hot water
1
Place an adequate water container (with a heat-insulated handle) under the hot water dispenser. After having
moved the power switch into the lower position, you can dispense water (e. g. for tea) by opening the hot water
lever.
