• The machine in operation must never be covered, as there must be a proper air circulation around it.
• The machine must never be used with the fixed and/or mobile guards removed or with the safety devices
cut off. The safety devices must absolutely never be removed or tampered with. The panels covering the
machine must not be removed, as the machine contains live parts (there is the risk of electric shock).
• When cleaning the machine, avoid using products such as alcohol, petrol or solvents in general; use water
or neutral detergents.
• To clean the machine frame, it is sufficient to use a moist cloth or a sponge. Avoid using abrasive products
that could damage the elements on the body. To clean the coffee serving units, the filter-holding cups, the
grills and the trays, follow the instructions of the Routine Maintenance chapter.
• For better product quality, replace the hot water in the boiler and circulate the water in the pipes upon first
turning the machine on in the morning. If the machine is expected to remain idle for a few hours during
the day, we also recommend changing the water by running it through the hot water tap and the coffee
serving units.
1.2.3 Maintenance - warnings
• Strict compliance with the routine maintenance instructions of this manual is required for a safe and effi-
cient operation of the appliance.
• The use of the appliance and the routine maintenance and cleaning operations may only be carried out by
authorized personnel, under the responsibility of the client.
• The scheduled maintenance and repair should only be performed by authorized and qualified personnel.
• Before carrying out any machine cleaning or maintenance operations, unplug the power cable, if possible,
or disconnect the omnipolar switch upstream of the machine.
• Don’t clean the appliance with a jet of water.
• If the power cord is damaged its replacement should be performed only by authorized and qualified personnel.
• The safety devices must always be in a perfectly efficient state, as regularly maintained by the authorized
La San Marco service personnel.
• The hot parts of the machine (serving units, boiler, piping, etc.) can cause serious burns due to accidental
contact with the skin. It is therefore necessary to use safety gloves, aprons, etc., during maintenance or
repair operations.
• In case of malfunctions or failure of any machine component, contact the authorized service centre and
request original La San Marco spare parts. The use of any other than original spare parts voids the con-
formity certifications and the warranty that accompany the machine.
• Any changes carried out on the machine and/or failure to carry out the scheduled maintenance will
release the Manufacturer from any liability for any resulting damages and voids the conformity declara-
tion and the warranty.
• Unauthorised operations or operations whose methods of execution are not exactly clear or unauthorised
interventions on the machine are strictly prohibited; contact the manufacturer for any information, spare
parts or accessories that you may need.
• Should the appliance be moved outdoors or to premises where the temperature might drop below 0°C, it
is vital that the exchangers circuit be emptied, cutting off the water supply to the appliance and draining
all water from the units until they only emit steam. Omitting to perform this procedure could lead to the
exchangers breaking, due to the water inside them freezing.
• For a proper disposal of the machine when it is to be discarded, contact the supplier or the authorized
firms specialized in the collection and disposal of solid urban waste. Do not discard the appliance in
the environment.
