English126.11 Programming of dispensing keysAll the dispensing keys , , , , andare equipped with a self-learning memory.Once they are programmed, they supply the same drink quantityat every subsequent command.Their programming is obtained as follows:- machine on and ready for use;- container positioned under the dispenser;- press and hold down the key to be programmed (or re-pro-grammed) until the drink reaches the desired level;- the display will show “PROGRAMMING”;N.B.: The message displaying is accompanied by the sound ofan intermittent buzzer.- release the key to automatically set the dosage dispensed;- a subsequent short pressing of the key (less than 1 sec.) allowsthe dispensing of the programmed dose.The programming of the keys implies at least one dispensing in-stance for each machine key.N.B.: The programming of key is obtained through function“HOT WATER PROGRAMM.” in “ON” mode (see “6.14Menu-programmable functions”).N.B.: The button can be programmed by pressing the jugbutton first and then by pressing (and keeping pressed) thebutton till the beverage reaches the desired level.ImportantEven if the machine is cut out, it keeps the programmed datain memory.18fig. 106.12 Grinder adjustmentGrinding adjustment changes according to the Country in whichthe machine is utilised and according to the coffee blend utilised.It is a most important operation to obtain the correct density andcream quantity in the drink dispensed.The grinding has been set during the testing phase according tostandard values, but adjustment modification is possible in anycase.- Open the front door (ref. 13, fig. 1-10), rotate the knob (ref.18, fig. 10) anti-clockwise to obtain finer grinding (the indexmoves towards a lower value), or clockwise to turn to a coars-er solution (the index moves to a higher value).ImportantDepending on the coffee blend utilised, fine grinding (indexon low values) increases the density and creaminess of thedrink and the connected dispensing time; vice versa a coarsergrinding (index on high values) decreases density, creami-ness and dispensing time.DangerDo not rotate the knob (ref. 18, fig. 10) anticlockwise to thelimit stop; this operation causes the jamming of the grindersand the machine blockage.ImportantShould the grinders jam due to the presence of foreign bod-ies in the bean blend, the machine locks showing message“GRINDER ERROR” on display.It will then be necessary to place a call with the AUTHORISEDSERVICE CENTRE (see “7.3 Jamming of the coffee grinderunit”).13
