Functional principles of the water system
Freshwaterisfedbytheoscillationpumptothewatertankintothehotwaterboiler.
Therequiredamountisspeciedbytheowmeter.
Theoscillatorpumpproduces,dependinguponow,apressurebetween3and15bar.
Thebrewingwaterisbroughtfromthehotwaterboilerthroughthebrewingvalveto
thebrewingunitforbrewing.Afterthebrewingprocess,pressureinthebrewingunit
isreleasedthroughthereleasevalve.
