6.2 Pressure switch adjustment

The pressure switch shown in the figure acts to keep the

boiler pressure constant by engaging or de-activating the

electrical heating resistance.

This pressure switch is already calibrated to 1.1-1.3 bar

during the initial machine testing stage, but should a different

working pressure be required, it is possible to vary the

operational field of the pressure switch using the regulation

screw (U); pressure reduction results in a reduction in tempe-

rature, whilst increasing the pressure will also increase the

water temperature. The regulation direction is shown in the

figure and on the pressure switch itself. The pressure varies

by 0.1 atm for every complete screw turn.

Warning: Disconnect the electricity supply before

undertaking this operation.

6.3 Pump pressure calibration

Insert the filter holder into the unit filled with regularly ground,

dosed and pressed coffee.

Switch on the unit switch (AROMA SM) or the unit control

keyboard (AROMA SE) (16) and read the pressure on the

pump pressure gauge (10).

NB: The correct pressure is of 8-9 atm.

Should the pressure indicated on the pressure gauge be

incorrect, turn it clockwise to increase the pump pressure

and anti-clockwise to reduce the pressure.

Once adjustment is complete check pump calibration by

delivering one or more coffees.

Z= Pump pressure adjustment screw.

Warning !!

When the machine is new the filter-holder sump may

not be aligned (perpendicular to the machine itself)

as shown in the figure at the side, however this does

not effect the efficient function of the same.

After a short period of use the sump will gradually

settle into a correct position.

6.4 Filters for coffee machine

Depending on the quantity of coffee ground, the appropriate

filter must be used as shown below to avoid that, once the

coffee has dripped out, the leftover powder remains attached

to the nozzle.

IMPORTANT: N°2 under-tile packings with are thinner

(8.1mm ) than that fitted as standard are included. These

packings may be used in the event of difficulty with inser-

tion of the filter holder.
