USE OF THE MACHINE

6.1 Preparation of the machine

The switched off machine is to be placed into operation as follows:
1. Make sure that there is sufficient water in the glass water tank. Refill water if necessary.
2. Turn on the machine (the switch is on the back of the machine and lights up orange when switched on).
3. The heating period depends on the ambient temperature and is approx. 10 minutes. The indicator of the
pump pressure gauge may move slightly during the heating-up phase.
4. The Puristika is ready for use as soon as the programmed temperature has been reached.
5. Insert the portafilter, move the brew group lever into the upper position and dispense some hot water.
This way, the portafilter will be completely heated.
It is recommended to leave the portafilter in the brew group, keeping it warm for optimum
coffee extraction temperature.

6.2 Manual adjustment of the brewing pressure

You can individually adjust and change the brewing pressure by turning the expansion valve, choosing a
value between approx. 8.5 and 12 bar.
To adjust the brewing pressure, proceed as follows:
1. Place the portafilter with the blind filter (filter without holes) into the brew group
2. Operate the brew lever and read the brewing pressure on the pump pressure gauge.
3. Set the brewing pressure to the desired value during brewing by turning the expansion valve.
Brewing pressure:
You can reduce the brewing pressure by turning the screw anti-clockwise and increase it by turning it
clockwise.
Only adjust the brewing pressure with the blind filter.
•
Caution, the handle can be hot with time!
•
• Frequent adjustment of the brewing pressure has a negative effect on the coffee and
leads to faster wear of the O-ring, the expansion valve.

6.3 PID-Temperature Control

The PID-Temperature control allows you to adjust the current temperature of the coffee boiler. This means
that you can extract your espresso at a variety of temperatures. The PID-display indicates the boiler
temperature.
Temperature (here 93°C)
The dot indicates the heating interval:
- Permanent dot = the machine is heating
- Flashing dot = the temperature regulates the set temperature.
