Since September 2006 we install this mixing manifold in every Mirage. The cold water enters from the right. The incoming cold water is directed towards four destinations: the heat-exchanger manifold, the boiler fill solenoid, the pump pressure gauge and the centre of this manifold, passing through the solenoid at the right.

The hot water from the main boiler enters from the left, passes through the left hand solenoid. These solenoids open simultaneously, hot and cold water mix and rush towards the hot water wand at the front of the machine. Underneath the cold water solenoid a jet restricts the amount of cold water.

The pump is activated together with the two solenoids to prevent any difference in temperature and quantity when coffee is brewed during hot water dispensing.

The result is a non-spattering flow of hot water from the wand, with a temperature of approx. 93 degrees Celsius. Perfect to prepare an Americano (Lungo) with an espresso shot brewed into the hot water in the cup.

An additional benefit is less strain on the main boiler capacity because a smaller quantity of hot water is needed to reach the same level in the cup.
