Cleaning The Steam Spout; Substitution Of Boiler Water; Idle Periods; Safety Devices - SM TOP 85 Serie Traduction De La Version Originale Du Mode D'emploi

12.3 Cleaning the steam spout

Clean the steam spout with a sponge or a moist cloth at the end of the working day to remove all traces of milk or other
substances that inevitably form during the normal operation of the machine. Open the steam tap, placing the spout in
the tub, to remove any residues which may have accumulated in the spout.

12.4 Substitution of boiler water

To change the water inside the boiler, proceed as follows:
1) Cut off the power supply to the machine by turning the main switch 1 to position 0 (zero).
2) Remove the tub and the cup support grille and open the boiler drain tap.
3) Open a steam drawing valve to facilitate the draining of the water until the end of the operation.
4) When water no longer comes out of the boiler, close the boiler drain and the steam drawing tap.
5) Charge the machine with water following the instructions of paragraph "Charging the water in the boiler".
6) To improve product quality, it is recommended to replace the water in the boiler and to change the water
contained in the water circulation pipes when starting the machine every day.

13. Idle periods

If the machine is to remain idle for long periods (weekly closing days, holidays, etc.), take the following precautions:
1) Turn the main switch to 0 (zero) and as necessary disconnect the power cord or the main switch of the
electrical mains.
2) Close the cut-off valve of the water mains.
3) If you think the temperature might drop below 5 °C, completely drain the water system of the machine.
4) Wash the components of the machine as described in the paragraph on routine maintenance.
5) Cover the machine if necessary.

14. Safety devices

15.1 Manual reset safety thermostat

The safety thermostat is located next to the control unit and can be accessed by removing the left side panel
from the machine. The thermostat probe, placed inside the electric heating elements, cuts the electric power
supply any time there is an abnormal increase in temperature. The heating elements will no longer hear the
water in the boiler and it will not be possible to use the machine correctly. Contact a technician from the LA
SAN MARCO SPA technical service centre.
The safety thermostat will have to be reset by the specialized technician LA SAN MARCO SPA,
who must first remove the cause of the malfunction.

15.2 Safety valve

The safety valve is installed on the upper part of the boiler, in the part corresponding to the area occupied
by the steam. The valve is activated if there is a considerable pressure increase inside the boiler. The valve
rapidly lowers the pressure by expelling the steam in the atmosphere (the valve trips in at 2÷2.5 bar). If the
safety valve trips in, the steam is held and dissipated inside the machine frame, so as to avoid hazards for
the persons around the machine.
In case of activation of the safety valve, switch off the machine and immediately contact the spe-
cialized technician.If the safety valve is set off, switch the machine off and immediately contact
the authorized La San Marco technician.
