7 . 1 0 EA SY CR EAM (O P T ION AL )
The E1 PRIMA is also available with the
Easycream system, which allows the baris-
ta to obtain a dense, velvety milk cream
quickly and automatically.
Easycream is composed by a steam wand
and a temperature probe.
The steam wand is connected to steam
boiler (A) and to an air compressor (B), so
that it can dispense steam and air.

Easycream needs two kind of settings.
One is software and one is mechanical.
As software setting, in the programming
there are three parameters to set:
• Delay (sec): is a delay for the air. When
Easycream begins, steam comes out with-
out air to start the rolling phase, then after
the delay time the air solenoid valve opens
and the compressor starts to push air into
the circuit together with steam, foaming
the milk. This time is to avoid the big bub-
bles creating at the beginning. Suggested
value is 1.5 sec, as in the example.
AirTemp (°C): is the temperature when the
•
air stops. The temperature probe checks
continuously the milk temperature. Air is
injected by the compressor into the cir-
cuit till the AirTemp parameter, and then
only steam comes out to roll the milk
with the foam creating the micro-bub-
bles. Increasing this parameter gives more
quantity of foam, decreasing it gives less
quantity of foam. Value is 40.0°C in the
example.
• FinalTemp (°C): The mechanical setting
consists in to adjust the air tap on top of the
machine to get a proper foam quality. It is
a flat screw to open and close the air. The
machine arrives with a basic setting, but if
a maintenance has been done, the start-
ing point is to close completely the screw
clockwise and then open anti-clockwise
about 2 complete turns. Value is 65.0°C in
the example.
