appliance by a person responsible for their safety. Children must be supervised to make sure they do not
play with 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.
•
Do not install the espresso coffee machine in places where cleaning is likely to be carried out with jets
of water.
•
The machine must never be switched on before connecting it to the water supply.
•
The user must make sure that the water supply valve remains open when the machine is switched on.
Place only empty cups in the cup holding shelf.
•
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).
•
Before carrying out any machine cleaning or maintenance operations, unplug the power cable, if pos-
sible, or disconnect the omnipolar switch upstream of the machine.
•
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.
•
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 prod-
ucts 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.
•
Strict compliance with the routine maintenance instructions of this manual is required for a safe and
efficient operation of the appliance.
•
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 declaration
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.
•
La San Marco S.p.A. reserves the right to make any technical changes on the machine considered nec-
essary without advance notice.
