    Note: The water softener is considered an essential device to guarantee a proper operation of the espresso coffee machine. A water softening system should be provided in order to guarantee the efficiency, performance and duration of the components in the machine. 3.4 Installation of water system INTERNAl PUMP Use the tube a (900 mm, supplied with the appliance) to connect the cut-off valve of the water mains to the tap 1 for water inlet to the water softener (figure 3). Connect the tube b for internal pump suction to the tap 2 of the water softener (figure 4).

    Note: An external pump can be installed on the coffee machine upon request. The pump operating pressure is calibrated by lA SAN MARCO SPA at a value of 9 bar. Should you wish to change this value, proceed as follows: The standard location for the pump is the right side of the machine (looking at it from the work zone). To access it, the right side must be removed (figure 11).

    The mixer can be calibrated by turning the adjustment screw, which is accessed from the upper tray (figure 17). The mixer calibration is factory set by lA SAN MARCO SPA. If you want to increase the temperature of the hot water drawn, turn the screw clockwise. On the contrary, if you want to decrease the temperature of the water, turn the screw anti-clockwise.

    The steamer must be used with care: contact of the skin with the steam spout or with the jet of steam itself can cause serious burns. Grip the burn protection sheath to change the position of the steam drawing spout. Never aim the jet of steam at persons or at objects which are not con- nected to the use described in this manual. Note: Before using the steam drawing spout, drain any condensation which may have formed within it into the tray. After using the spout, wipe it clean with a damp cloth, and if necessary drain any residue remaining inside it into the tray. 6.3 Drawing hot water Hot water is drawn by the appropriate spout and can be used to prepare infusions, tea, camomile tea, to heat cups, to add water to an espresso and to obtain American-style coffee, and so on. 6.4 Cup heater (optional) The cup heater is used to increase the heating of the upper cup support surface (by means of an electrical heating element).
