1. Introduction
Before using the machine, carefully read all of the instructions contained in this machine.
1.1 Using the manual
This manual contains all information required for the installation, use and maintenance of the
coffee machine.
This manual is an integral part of the machine; always keep it intact together with the appliance.
1.2 Warnings
•Do not operate the machine or carry out routine maintenance before reading this manual. La
San Marco S.p.A. reserves the right to make any technical changes on the machine consid-
ered necessary without advance notice.
1.2.1 Installation - warnings
• TheinstallationmustbecarriedoutbyauthorizedLaSanMarcotechnicalpersonnel.
• This machine must be installed only in places where its use and its maintenance are made by trained personnel.
• Thecoffeemachineisdeliveredinasuitablepacking.Thepackingcontainsthemachineanditsaccesso-
ries, the user manual and the conformity declaration. After opening the packing, check the proper condi-
tion of the coffee machine and its components. In case of doubt, do not use the appliance, and contact
La San Marco S.p.A.
• All of the packaging must be carefully conserved in case the machine needs to be transported in the future.
• Themachineshouldbeplacedonaperfectlyhorizontalplaneataheightofnotlessthan800mmabove
thefloor.Thehorizontalplanemustbesufficientlysturdytosupporttheweightofthemachine,witha
sufficient clearance around it to dissipate the heat generated during its operation.
• Thedevicemustbeconnectedtothelocalwatermainsusingaflexiblepipefittingincompliancewith
national standards, if these are applicable. Furthermore, the equipment must be installed with suitable
“refluxprotection”inordertocomplywiththeapplicablenationalandlocalregulations.
• Connecttheappliancetothewatermainsupplyusingonlytheequipmentprovided.
• Do not install the espresso coffee machine in places where cleaning is likely to be carried out with jets
of water.
• Forsafetyagainsthazardsrelatedtoelectricalcurrents,keepthemachineawayfromsinks,tubs,aquari-
ums, taps, and areas that are wet or where water may splash.
• Themachinecreatesheat.Thereforeitneedstobeplacedinaroomthatissufficientlyventilatedtoensure
heat dissipation.
• Keepthemachineawayfromsourcesofdirectheat.
• Makesurethatthevoltageofthepowersocketdoesnotdifferfromthatindicatedonthetechnicaldata
and on the identification tag on the machine. If the voltage is different, do not connect the machine. This
may be dangerous and may damage the unit.
• The electrical connection must be carried out in accordance with the regulations of the country of installation.
1.2.2 Use of the machine - warnings
• 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.
• Thismachineisdesignedandbuiltforservingespressocoffee,hotwater(forthepreparationofbeverages
andinfusions)andsteam(usedtoheatliquids).Theuseofthemachineforanyotherthanitsintended
purposesisconsideredtobeimproperandunauthorized.Themanufacturerdeclinesanyliabilityfordam-
age resulting from the improper use of the machine.
• Theusermustbearesponsibleadult,whoisexpectedtocomplywithlocalsafetyrulesandaccepted
common sense procedures. For a proper and safe use of the machine, the operator must always comply
with applicable accident prevention and other work safety and health regulations.
• Thisapplianceisnotdesignedforusebypersons(includingchildren)withlimitedphysical,sensoryor
mentalabilities,orlackinginexperienceandknowledge,unlesstheyarecontrolledandtaughttousethe

• 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

rent, do not connect the machine. This may be dangerous and may damage the unit.
3.1 Equipment provided
The machine packing contains the equipment kit, which includes the following items:
– lter cups with lter restraint ring
– lters for lter cups (single and double doses)
– blind lter for lter cup
– spouts for lter cups (single and double doses)
– press for ground coffee
– rubber tube with stainless steel mesh for water connection (water circuit - water softener)
– rubber drain hose with steel coil for water drain
– 3/8” nipples for hose connection to water supply tube
– cleaning brush for serving units
– inclined cup grip protection
3.2 Water mains set-up
FEEDING LINE
Bring the water feeding tube (of at least 3/8” diameter) up to the machine and install an on-off valve (preferably of
3/8” ball type) that allows a rapid opening and closing operation. The machine should be connected to the water
mains using the tube supplied with it. Do not connect the machine with used tubes.
DRAIN LINE
Provide an inspectable drainage pit on the oor connected with the sink drainage line, suitable for receiving
the machine gravity drainage tube. The drain tube must be positioned so that the water ows out freely, with-
out possibility for the pipe to clog up during the operation.
3.3 Water softener (optional)
The water softener for softening the mains water can be manual or automatic, depending on
customer’srequest.
Before connecting the water softener to the coffee machine, the resins contained in it should be
washedoffasdescribedintheuser’smanualsuppliedwiththeappliance.
Note:
The water softener is considered an essential device to guarantee a proper operation of the espresso coffee ma-
chine.Awatersofteningsystemshouldbeprovidedinordertoguaranteetheefciency,performanceandduration
of the components in the machine.
