When the boiler has been charged, the coffeegroup starts heating (4) for about 7 minutes. When the indicators (2) stop flashing, the group (4) has reached the correct thermal level and can be used to make coffee. When the group has the correct thermal level, you can turn on the switch (1b) to heat the boiler. When the manometre controlling the boiler pressure reaches 1,5 bar, it is possibile to use the drawing tap for steam (5)and hot water (6). PREPARATION OF ESPRESSO COFFEE In order to always obtain a good coffee, the filter-holder (9) must be continuously connected to the coffee group (4 ) so that it is always at the correct temperature. Take away the filter-holder (9), avoiding to touch the hot metallic parts. Afterwards clean the filter within the filter-holder from the possibile remains of used coffee. Then charge the filter with new ground coffee (1 coffee dose for the one shot filter, 2 doses for the twoshots filter), press the ground coffee with the appropriated manual coffee-tamper with which the machine is equipped and clean the filter edge from possible coffee remains. Firmly connect the filter-holder to the coffee-group (4). Place the cups on the shelf 12 (whose height can be regulated according to the dimensions of the cups) and press one of the two automatic dosing buttons P1-P2. When the indicator of the pressed key goes off, coffee is ready. NOTE This machine has three buttons to make coffee, 2 ( P1 and P2) of which electronically dosed and one with continuous supply function and stop (P). The two dosed buttons must be regulated by the technician at the moment of the installation in accordance with the user, who must not try to change the programming on his own initiative. ATTENTION Do not put the hands under the coffee groups when they are functioning. Do not touch metallic parts of the coffe groups and of the filter-holders because they may cause bad burns. HOT MILK PREPARATION 4
