User Manual MECHANIKA V SLIM
20
The MECHANIKA V SLIM has a fuse to prevent the machine from overfilling.
It is possible that the machine does not heat up when using it for the first time or when dispensing
large quantities of water through the hot water valve. In this case please switch the machine off and
on again.
6 USE OF THE MACHINE
6.1 Preparation of the machine
The switched off machine is to be placed into operation as follows:
1
Fill water into the water tank, if necessary.
2
Turn the machine on (power switch in position “1”).
3
Wait until the pressure gauge indicates approx. 1.0-1.25 bar.
4
Depending on the ambient temperature, the heat-up phase is approx. 15 minutes.
5
The machine is now ready for use.
6
Insert the portafilter and move the brew group lever into the upper position. Release some hot water. Thus, the
portafilter will be completely heated.
It is recommended to leave the portafilter in the brew group keeping it warm for optimum
temperature for coffee dispension.
6.2 Manual adjustment of the brewing pressure
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 portafilter 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
Put the group lever back into the lower position. Remove the portafilter from the brew group, then remove the
blind filter and insert a coffee filter again.
7
Now the machine is ready for use again.
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 large 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 approx. 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.
