OPERATING PRINCIPLE

1.1

General operation

The machine works according to a pump system developed by Bravilor Bonamat. This system has the
following advantages:
D The components that ensure that the water is dosed properly are in the cold water circuit.
This reduces the main cause of failures, namely the formation of limescale on the dosing valves, to a
minimum.
D The float that regulates the water level is also in the cold water circuit.
This also reduces scaling to a minimum.

Water dosing system

Pressing a selection button triggers the pump motor, which has a controlled time and speed. The pump rotor
moves a certain amount of cold water from the cold water reservoir to the bottom of the boiler. This pushes
the hot water in the boiler upwards towards the water selector. This selector selects its position by means of
a rotating movement (drink−dependent). Depending on the selected drink, an ingredient is dosed and mixed
in the mixing chamber with the dosed water before flowing into the cup.
