12. SUGGESTIONS FOR OBTAINING GOOD COFFEE

To obtain high-quality coffee, it is important that the hardness of the water used does not exceed 4-5 °f (French degrees). If the
water hardness exceeds these values, it is advisable to use a water softener.
Avoid using a water softener if the water hardness is less than 4 °f.
If the taste of chlorine in the water is particularly strong, a special filter should be installed.
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.

13. LIST OF HAZARDS

This chapter describes possible hazards for the user if the specific safety standards (described in this manual) 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 discharge elec-
tricity to earth.
Do not use running water for washing.
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.
Do not touch the dispensing unit
The high temperature of the dispensing unit may cause burns Avoid contact of the dispensing unit with the hands or other parts
of the body.
Be careful of the tips of the pod perforator
During cleaning, be careful of the tips of the pod perforator located inside the clamping ring of the group.
Be careful with the steam and hot water nozzles.
During use, the steam and hot water nozzles may overheat, thus becoming a source of danger. Handle these parts carefully. 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 maintenance or repair work on the machine you must turn it off by means of the main network switch or,
better 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 tap and dry-running the delivery group for a short time. Switch off the
machine and open all the steam and water taps. When the pressure is zero, completely empty the boiler, unscrewing the special
pipe fitting located 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.
Use of the appliance
This espresso coffee machine is an appliance for professional use only. Any other type of use is considered incorrect and therefore
dangerous. Never allow children or incapacitated persons to use the machine.
Non-observance of the above 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.
