10. 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 as it is no longer able to discharge electricity
to earth.
Do not use running water for washing
The use of pressurized water directly on the machine can seriously damage the electrical equipment. Never use water jets to wash
any part of the appliance.
Do not touch the delivery group
The high temperature of the delivery group may cause burns. Avoid contact of the delivery group with the hands or other parts
of the body.
Be careful of the perforator tips
During the cleaning operations, be careful of the tips of the perforator located inside the clamping ring of the upper group.
Be careful of the steam and hot water nozzles
During use, the steam and hot water nozzles become very hot and are thus a potential source of danger. Handle these 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 maintenance or repair work on the machine you must turn it off using the main switch or, better yet, discon-
necting the mains connection terminals. 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.
Thus you must empty it beforehand by remove the water in the tank 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, empty the boiler completely by unscrewing the
special pipe fitting located on the lower part of boiler.
If the above procedure is not carried out correctly, opening any part of the hydraulic system can cause a sudden outburst of
superheated 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 rules 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 disconnecting it from the mains before carrying out any operation.
