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 NEW 105 Practical models, when water reaches the level probe, filling stops and the green “MAX”
lED of the electronic level control is turned on. In the other models of the NEW 105 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).
The main switch can be turned to two positions (
1
and
2
). Position
1
starts the electronic auto-
matic 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
(the electrical heating elements must always be submerged in water in
order to operate).
5. Adjustments
Any adjustments to the coffee machine must be carried out by qualified technical staff authorised
by LA SAN MARCO SPA.
