22. LIST 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 discharge electricty 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 carefully. Never direct

steam or hot water jets directly on parts of the body.

Do not intervene 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 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 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 dan-

gerous. Never allow children or incapable persons to use the machine.

Non-observance of the above-described standards can cause serious damage to people 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.

WARNING

Any action taken by a technician on the electronics of the machine when the machine is still supplied with electrical power

automatically invalidates any guarantee.

The technician needs to be aware that the machine is electrically connected and act accordingly.
