3) Open the water supply on-off valve.
4) Open a steaming tap 6 (figure 1) to allow the exit of the air in the boiler filling phase.
5) Reinstall the tray and cup holding grill in its place.
6) Turn the knob of the main switch to position 1 so as to carry out automatic filling of the boiler with water.
In models NeW 105 Practical, when water reaches the level probe, filling stops and the green "MAX" LeD
of the electronic level control comes on. In other models of the NeW 105 series, when water reaches the
level probe, filling stops and the blue "OK" LeD of the electronic level control comes on.
Note:
when the boiler is filled with water, it may take longer than 150 seconds, after which the automatic level alarm
trips (see the chapter on display of alarms). If this happens, turn the main switch to 0 (zero) and then back to
1. Then perform automatic filling of the boiler again (as described in point 6).
To keep the automatic level alarm from occurring, just speed up automatic filling of the boiler using the manual
filling button f (figure 8).
The main switch can be turned to two positions (1 and 2). Position 1 starts the electronic automatic
level function to fill the boiler and excludes the operation of the heating elements. Position 2 starts
the heating elements to heat the water. Never start the coffee machine by turning the main switch
to position 2 (in order to work, the heating elements must always be immersed in the water).
5. adjustments
Any adjustments to the coffee machine must be carried out by qualified and authorized staff from
LA SAN MARCO SPA.
5.1 Adjustment of the boiler water level probe
The level probe is normally placed in a standard position for all models of the NeW 105 series.
However, if the client so desires, it is possible to increase or decrease the amount of water in
the boiler by adjusting the level probe as shown in the figure.
5.2 Adjustment of pump serving pressure
In models of the NeW 105 series, the pump is located inside the coffee machine.
Note:
On request, an external pump can be installed on the external pump.
Calibration of the pump operating pressure is set by LA SAN MARCO SPA at 9 bar. If you want to change this
value, proceed as follows:
1) 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).
2) Press the continuous serving button to dispense water from a serving group.
3) On the lower graduated scale of the gauge, read the pump operating pressure.
4) Adjust the pressure using the adjustment screw of the internal pump (figure 11) of an external pump (fi-
gure 12). To increase the pressure, tighten the screw and read the corresponding value on the lower scale
of the gauge. To decrease the pressure, loosen the adjustment screw.
