• The espresso coffee machine must be started by qualified technical personnel author-
ised by LA SAN MARCO SPA.
• Once the electric and hydraulic connections are completed, the user is advised to start
the espresso coffee machine with the following procedure in order to avoid damaging
the appliance.
4.1 Filling the boiler with water
1) Check that the main switch of the appliance
1
(figure 1) is set to position
0
(zero).
2) Remove the tray and the cup support grill and make sure that:
a) The boiler drain valve
a
is closed (figure 8).
b) The taps of the automatic level valve
b-c
must be open (figure 8).
c) The taps of the volumetric meters
d
must be turned on (figure 9).

3) Open the water supply on-off valve.
4) Lower the lever of a steam tap in order to allow the release of air while filling the boiler with water.
5) Reinstall the tray and cup support grill in its place.
6) Turn the main switch knob to position
1
so as to carry out the automatic filling of the boiler with water. In
the models of the NeW 105 TOUCh series, when water reaches the level probe, filling stops and the blue
“OK” LeD of the electronic control is turned on.
Note:
when the boiler is filled with water, it may take longer than 150 seconds, after which the automatic level alarm
is triggered (see the chapter on display of alarms). If this happens, turn the main switch to
0
(zero) and then
back to
1
in order to perform automatic filling of the boiler again (as described in point
6
).
To prevent the automatic level alarm from being triggered, just speed up automatic filling of the boiler using
the manual filling button
f
(figure 8).
