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.

6.3Pump 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.

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.
