The hydraulic circuit of the E1 PRIMA fol-
lows a new technology: NEO (New Engine
Optimization).
The NEO engine uses an instant heating
system allowing only the necessary amount
of water for the extraction.
To be heated, thus using less amount of
water and boiler optimization. Productivity
and performance remain constant, while
energy efficiency increases.
Before proceeding with the operations
described in this chapter make sure
that the machine is turned OFF and
07
unplugged from the mains.

The exhaust manifold (A) is placed on the
front of the machine.
It collects the exhaust pipes of: the coffee
boiler's expansion valve, the coffee valve
and the steam valve.
When the machine is closed, the exhaust
manifold drains into the drip tray.
Below and behind the exhaust manifold
there is the drain box (B).
It collects the waste water of the drip tray,
only when the drip tray has been drilled.
This occurs when it is preferred to use a
direct waste water system: in this case, the
drain box is also connected to the waste
water pipe.
