2. GENERAL SAFETY RULES

Attention

During the repair of the machine all the normal
safety protections, designed to avoid accidents
are disabled. Adopt all the measures necessary
to avoid accidents.

• Power connection should be made in compliance
with local standards in force.

• The electric socket connecting the machine should:

- conform to the type of plug installed on the machine;

- comply with the data provided on the plate placed on
the bottom of the apparatus;

- be connected to ground.

• The electric parts of the machine must not:

- enter into contact with any type of liquid: danger of
electric shock and/or fire;

- be manipulated by humid or wet hands;

- be tampered with.

• It is forbidden:

- To use the machine near flammable substances
and/or explosives and/or in an atmosphere with any
risk of fire;

- To use spare parts not advised by the manufacturer;

- Carry out any type of technical modification not cove­red in the normal procedures of diagnosis and repair.

• Before carrying out any operation on the machine
ensure that the plug is disconnected from the current
and that the machine has cooled.

• Maintenance operations on the machine should be
carried out by a single person; if a second person
must intervene, this person should be advised of the
potential hazards relevant to the operation underway.

• In case of fire use carbon dioxide (CO2) extingui­shers. Do not use water or powder extinguishers.

Attention

Read the entire manual carefully and the follo­w

ing general safety rules..

2.1. Stop functions

To stop the machine turn the main switch to “0” (OFF).

2.2. Safety devices

Two Klixon thermostats with manual reset avoid any

overheating of the boiler.

2.3. Residual risks

In this chapter are illustrated the risks that the user may
incur in if he doesn’t comply with the specific safety
rules (as described in this booklet).

The appliance must be connected to ground

If it is not done, the appliance can become 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 pressurised 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 hot water pipe

During use the hot water pipe may overheat, thus
becoming a source of danger. Handle this part care­fully. Never direct steam or hot water jets directly on
parts of the body.

Do not work on the machine when it is powered

Before carry out any maintenance or repair 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
panels when the machine is supplied with electrical
power.

Note

The machines described in this publication, are
designed in compliance with the specific European
standards in force and therefore have measures of
protection in all the potentially hazardous parts.

Use of the appliance

This espresso coffee machine is an appliance for pro­f

essional use only. Any other type of use is considered
incorrect and therefore dangerous. Never allow chil­dren or incapacitated persons to use the machine..

Attention

Non-observance of the above rules can cause
serious harm to people, property or animals.

Never operate the electronic components when
the machine is still supplied with electrical power.

Shut off the machine completely by unplugging it
from the mains before carrying out any operation.

Warning

Do not use any containers that are not suitable for
foodstuffs.

Attention

Burn danger – During hot water and steam
dispensing, do not direct the jets toward others
or yourself. Grasp the pipe, exclusively on the
relevant protectors (12 and 17).

Attention

Any operation taken by the technician on the elec­tronics of the machine when the machine is powe­red, automatically invalidates any guarantee.

The technician should know that the machine is
electrically connected and act accordingly.

3. INSTALLATION

3.1. Unpacking

O

pen the packaging, taking care not to damage it.
Remove the machine protections and the equipment
contained in the package.
Take the machine out.

Warning

It is prohibited to install the machine outside or in
places where water or steam jets are used.

Warning

The presence of magnetic fields or proximity with
electric machines which generate disturbances,
may cause malfunctions in the electronic control of
the machine.

Warning

With temperatures approaching 0°C there is the risk
of freezing internal parts of the machine which con­tain water. Do not use the machine under these con­ditions.

3.2. Mounting-Positioning

For the correct operation of the machine, the following
advice is given:

- environmental temperature: 10°C ÷ 40°C;

- maximum humidity: 90%;

- the area must be ready for the installation of the

machine;

- the place where the machine is installed should be

flat, solid and still; the surface must not have an incli-

nation of more than 2°;

- the area should be sufficiently illuminated, ventilated,

hygienic and equipped with a readily available power

outlet.

Attention

Sufficient space must be allowed to access the
machine and the plug, to allow the user to move
freely and to be able to immediately leave the
area in an emergency.
