7 As soon as the boiler is filled, there will be no more pump noise; the orange control lamp is now on. As
soon as the fresh water drops down to a certain level in the fresh water tank, the machine switches off
and the light of the orange control lamp switches off. Now refill fresh water. The machine heats up
automatically.
8 Because a large amount of water is required for the first filling of the boiler, the water tank has to be
refilled with fresh water.
9 Wait until the boiler pressure gauge indicates approx. 1.0-1.25 bar.
10 A manual "boiler ventilation" is not necessary because the MECHANIKA V SLIM is equipped with a
professional depression valve that ventilates the boiler during the heating-up phase.
11 Move the group lever into the upper position and dispense approx. 250 ml of water. This way, the heat
exchanger will be filled with water and the circulation of the water in the thermosyphon system begins.
12 Move the group lever into the lower position. Refill the water tank if necessary.
13 The machine is now ready for use. Put the cups on the cup heater tray in order to preheat them and enjoy
your coffee.
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.

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.
Turn the machine on (power switch in position "1").
2
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 big filter (2 cups) for the preparation of 2 cups. Make sure that the filter is
firmly locked into the portafilter.
Fill the finely ground coffee with the respective grind for espresso into the filter (approx. 7 g – 9 g).
Compress the ground coffee with the tamper. A tamping pressure of approx. 20 kg is recommended. Thus
the ground coffee is evenly compacted. Clamp the portafilter firmly into the brew group.
