OPERATING PRINCIPLE General operation The machine works according to a pump system developed by Bravilor Bonamat. This system has the following advantages: D The components that are responsible for the correct dosing of the water are housed in a cold water unit.

There is a second temperature sensor on the boiler (fig.1 ,3.C.). This sensor monitors the outlet temperature of the dosed water. If this sensor measures a too low temperature, the machine is blocked. No more water is dosed. ECopyright Bravilor Bonamat B.V.
D As a result, the hot water in the boiler is pushed out of the boiler. D The float and the magnetic valve ensure that the level in the float tank is maintained and that water remains in the pump chamber. ECopyright Bravilor Bonamat B.V.
Depending on the type of ingredient, “beater springs” are used in the canister. These springs ensure that less tunnel formation occurs. This is the caking of ingredient against the walls. ECopyright Bravilor Bonamat B.V.
The function of this exhaust system is to ensure that vapour from the mixing chamber does not get the chance to reach the ingredient holder outlet. Fig. 8 Ventilation system Fig. 6 Exhaust hood Fig. 7 Mixing unit ECopyright Bravilor Bonamat B.V.
