With the valueset to 0 (default) the function is disabled.TEMPERATURE SETTINGThis function is used to set the operating temperature,expressed in °C, of the boilers actually installed in themachine.DISPLAY PRE-SELECTIONSIt is possible to set which of the two available pre-selectionmessages is to be shown on the display:- Decaffeinated- Dark RoastDIRECT FUNCTIONSINSTALLATIONPress the installation button “3” to carry out the hydraulicsystem filling operations, even with the air-break full.RESETTING THE FAILURESPress the failure reset button “8”; the message “Running”is displayed for a few seconds and all present failures arereset.Important notice!!Access to the machine interior for maintenance and/orrepairs is via the back panel.Therefore the machine is designed to be rotated, thusallowing removal of the back panel.The integrity of the machine and compliance with thestandards of the relevant systems must be checked atleast once a year by qualified personnel.Before starting any maintenance operations requiringparts of the unit to be removed, the machine mustalways be switched off.The operations described below must be carried outonly by personnel who have the specific knowledge ofthe machine functioning from a point of view ofelectrical safety and health regulations.INTRODUCTIONTo ensure correct operation for a long period, the machinemust be subjected to regular maintenance.The following sections contain the procedures and themaintenance schedule, which are only a general indica-tion, as they greatly depend on the operating conditions(e.g. water hardness, environmental humidity and tem-perature, type of product used, etc.).The procedures described in this chapter are not exhaus-tive of all maintenance operations to be carried out.More complex operations (e.g. boiler descaling) should becarried out by qualified technicians only having specificknowledge of the machine.To prevent oxidation or the action of chemical agents, thestainless steel and varnished surfaces should be keptclean by using mild detergents (solvents must not beused).Under no circumstances should water jets be used toclean the machine.MAINTENANCE
