4. Start-up

• The coffee machine must be started by qualified technical personnel approved by La
San Marco.
• Once the electric and hydraulic connections are completed, the user is urged to start
the espresso coffee machine with the following procedure in order to avoid damaging
the appliance.

4.1 Charging the water in the boiler

Check that the machine main switch 1 (figure 1) is in 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).

3)
Open the water supply on-off valve.
Open a steaming tap 6 (figure 1) to allow the exit of the air in the boiler filling phase.
4)
5)
Reinstall the tray and cup support 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.
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 200 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 TOP 85 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.
