uggestions on how to obtain a good cup of coffee
To obtain a high-quality coffee, it is important that water hardness of the water used does not exceed 4-5 °F (French
degrees). In the water hardness exceeds these values, it is advisable use a water softener.
Avoid using a water softener if water hardness is less than 4 °F. If the taste of chlorine in the water is especially strong,
a special filter should be installed.
It is not advisable to keep large stores of coffee beans. Never grind large amounts of coffee. Use the amount the
doser holds and if possible use it by the end of the day. Never purchase ground coffee as it expires quickly.
After the machine has not been used for a period of time (2-3 hours) make a few dry runs. Be sure to carry out
regular cleaning and maintenance.
L
ist of hazards
This chapter describes possible hazards for the user if the specific safety standards described in this booklet are not
adhered to.
The appliance must be connected to an efficient grounding system
If this is not done, the appliance can be a source of dangerous electrical discharges in that it is no longer able to dis-
charge electricity to earth.
Do not use running water to wash
The use of pressurized water directly on the machine can seriously damage electrical appliances. Never use water jets
to wash any part of the appliance.
Be careful with the steam nozzles and hot water
During use, the steam nozzles and hot water may overheat, thus becoming a source of danger. Handle such parts care-
fully. Never direct steam or hot water jets directly on parts of the body.
Do not work on the machine when it is supplied with electrical power.
Before carrying out any intervention on the machine you must turn it off by means of the main network switch or bet-
ter yet, disconnecting the connection terminals in the network. Never remove any body panel when the machine is
supplied with electrical power.
Never work on the hydraulic system before having emptied it.
All work regarding the hydraulic system and the relative boiler are to be avoided when there is still water and pressure
in the system. You must therefore empty it beforehand, closing the mains cock and dry-running the delivery group for a
short time. Switch off the machine and open all the steam and water cocks and taps. With the pressure zero, completely
empty the boiler, unscrewing the special pipe fitting situated on the lower part of it.
If the above procedure is not correctly carried out, opening any part of the hydraulic system can cause a sudden outlet
of overheated water under pressure.
Lever machines
Never lower the lever if there is no coffee in the filter, or if the filter holder is not installed on the group: the sudden
upwards movement of the lever may damage the appliance and injure individuals.
Gas machines
Periodically check for gas leaks in the system by applying a soapy solution to the ducts.
For safety reasons, close the gas heating system when the machine is not in use (at night or during hours of closure)
Use of the appliance
This espresso coffee machine is an appliance exclusively for professional use. Any other type of use is considered wrong
and therefore dangerous. Never allow children or incapable persons to use the machine.
Non-observance of the above-described standards can cause serious harm to people, property or animals.
Never work on the electronic apparatus when the machine is still supplied with electrical energy.
Shut down the machine completely by unplugging it from the mains before carrying out any operation.
