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 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.

5.2 Calibration of pump pressure

a) Once the boiler is filled, turn the main switch to posi-
tion 2 (the heating elements start to heat the water).
b) Press the continuous-feeding push button for the
manual serving machines or the push button for the
electronic machines with automatic serving, so that
the water flows out of the unit corresponding to the
pressed button.
c) Read the water pressure value on the lower part of the
pressure gauge. The optimum pressure is 9 bar.
The pressure is adjusted to the desired value by
operating on the pump screw: the pressure is increased by turning clockwise; it is decreased by turning
counterclockwise. As shown in the following figure, there are three different cases for adjusting this screw,
depending on the pump installed on the machine:
