6.1 – PRESSURE SWITCH REGULATION (NOT APPLICABLE FOR
PUB E - PUB P MODELS)
The pressure switch shown in the picture has to keep the pressure
in the boiler constant, by activating or deactivating the electrical
heating element.
This pressure switch is adjusted during the final testing of the machi-
ne on a 1.1÷1.3 bar value; however, if the specific case requires
a different operating pressure, the pressure switch operating range
can be changed by operating on the regulation screw (U): by
reducing the pressure, you will obtain a temperature reduction,
by increasing the pressure, the water temperature also increases.
The regulation sense is shown in the picture and also on the pres-
sure switch itself.
The pressure changes approximately 0.1 atm for each complete
turn of the screw.
Caution! Disconnect the main cable before carrying out
this operation.
6.2 – PUMP PRESSURE SETTING (EXCEPT MODELS PUB E)
Insert the coffee filter into the filter-holder filled with properly
ground, dosed and pressed coffee. Switch on the unit control
keyboard (15) and read the pressure on the pump gauge (11).
N.B. The correct pressure is 8/9 bar.
If the pressure displayed by the gauge is not correct, operate on
the pump pressure regulation screw (Z), by turning it clockwise to
increase the pump pressure or anticlockwise to reduce it.
Once the regulation is completed, check the pump setting by delive-
ring one or more coffee servings.

Important! The PUB E models are equipped with a
vibration pump which does not need to be set.
Caution! When the machine is new, the filter-holder
may not be aligned (perpendicular to the machine
itself) as shown in the picture; this however does not
affect the proper use of the machine itself.

After a short period of use the filter-holder will be
gradually settled on the correct position.

B. Position of the closed filter-holder after the machine has been in
use for a brief period.
7 – COFFEE PREPARATION
In order to obtain an excellent espresso coffee, it is important to
use a top quality blended coffee, properly roasted and ground;
grinding is correct when the coffee delivery time is between 15-18
seconds for one serving and between 30-35 seconds for two
servings. The coffee should be grinded at the time of use. Once
ground, the coffee loses its flavour within a short time; if the grin-
ding is too coarse you will obtain light-coloured and weak coffee,
without froth; if the grinding is too fine you will obtain dark and
strong coffee, with little froth.
Warm cups contribute to maintain the right temperature of the
coffee delivery; it is therefore advisable, before using it, to place
the cups on the cups-holder grid (16), which will make it possible
to take advantage of the heat released by the boiler (avoid placing
the cups on the lid of the water tank for the PUB E model).
On machines provided with an electric cup-warmer, cups are pre-
ated by pressing cup-warmer luminous switch (27).

Caution! Do not place cloths, covers, etc. on the cup
holder.
Once you have placed the filter into the filter-holder (6), fill the filter
with the amount of coffee required for 1 or 2 cups (7 gr. - 14 gr.),
level it off, and press the coffee down with the presser, manually
clean the filter edge from any coffee residues and fit the filter-holder
into the brewing unit (5) moving it rightward tightly in its place.
Place the cups under the spouts and start the brewing using the
unit control (15).
