The hot water valve and the hot water dispenser must not be put out of operation.
The brewing valve is installed opposite to the flow direction so that the excess water
can be released when the boiler is heated without the boiler pressure climbing to
16 bar (opening pressure for the safety valve).
The release valve is opened when heating in order to discharge excess water.
The oscillating pump is connected for all dispensing operations from the boiler
(brewing, hot water dispensing, steam dispensing).
