EK MODEL
This appliance has an electronic control board which controls water level in the boiler, the activation
of the motor pump and the doses of the delivery groups (since the appliance has a water dosing
system based on flow meters). It also manages the visualization of any possible malfunction
through the LEDs on the touchpad.
OpERATING TEMpERATURE ADJUSTMENT FOR ELECTRIC HEATING SYSTEM
The electric heating system of the machine is already set by the manufacturer to work at a temperature
of
120 °C in the boiler, corresponding to 1 bar boiler pressure. This pressure can be viewed on the
pressure gauge (4) on the appliance.
In order to increase or decrease the boiler pressure, it is necessary to operate on the electric pressure
switch (Pict 12) which is inside the machine (on the right side), as indicated here below:
• Turn the adjustment screw anti-clockwise to
increase boiler pressure.
• Turn the adjustment screw clockwise to decrease it.
Boiler pressure (at operating temperature) is normally modified exclusively in order to adapt the machine
temperature to the particular type of coffee blend so as to obtain the best result in the cup.
GROUp DOSE SETTING
Hold down the button
of the first touchpad on the right (1st GROUP) for about
5 seconds until all
LEDs on the touchpad light up.
Within
30 seconds fasten a filter holder (11 b) containing a dose of ground coffee to the group; put a cup
below the filter holder and press the button “1 short coffee” (25) on the corresponding touchpad. The
LED for the selected dose will switch off to indicate that the dose is being set.
When the coffee reaches the required dose, press the button “1 short coffee” (25) again to stop coffee
delivey and confirm the required dose.
Repeat the same procedure for the other buttons (26-27-28) always referring to the first touchpad.
NOTE. Follow the above procedure to set all remaining doses, using the 1-cup coffee holder (11
b) or the 2-cup holder (11 a) according to the dose to be set.
WARNING!
Cut off power while operating on the pres-
sure switch.
