without the guards or with the protection devices deactivated.
• Do not remove, tamper with or make illegible the safety, danger and instruction signs
and labels on the machine.
• Do not remove or tamper with the machine’s safety devices.
• Before carrying out any machine installation, always consult the installation manual,

●PPE REQUIRED
○PPE AVAILABLE OR TO BE USED IF NECESSARY
—PPE NOT REQUIRED
1. During these operations, gloves must be cut-resistant. Failure to use the personal protection equipment by
operators, specialized personnel or users can involve exposure to damage to health (depending on the
model).
2. During these operations, gloves must be suitable for contact with chemical substances used (refer to the
safety data sheet of the substances used for information regarding the required PPE). Failure to use the
personal protection equipment by operators, specialized personnel or users can involve exposure to
chemical risk and cause possible damage to health (depending on the model).
A.4 Transport, handling and storage
• Due to their size, the machines cannot be stacked on top of each other during transport,
handling and storage; this eliminates any risks of loads tipping over due to stacking.
• Do not stand under suspended loads during loading or unloading operations.
Unauthorized personnel must not enter the work area.
• The weight of the appliance alone is not sufficient to keep it steady.
• For machine lifting and anchoring, do not use movable or weak parts such as: casings,
electrical raceways, pneumatic parts, etc.
• Do not push or pull the machine to move it, as it may tip over. Use proper tool to lift the
machine.
• Machine transport, handling and storage personnel must be adequately instructed and
trained regarding the use of lifting systems and personal protection equipment suitable
for the type of operation carried out.

A.5 Installation and assembly
• The installation must be carried out by a specialised personnel.
• Follow the installation instruction supplied with the appliance.
• Do not install a damaged appliance. Any missing or faulty parts must be replaced with
original parts.
• Do not make any modifications to the parts supplied with the appliance.
• Disconnect the appliance from the power supply before carrying out any installation
procedure. Connect the appliance to the power supply only at the end of the installation.
• The appliance is not suitable for installation outdoors and/or in places exposed to
atmospheric agents (rain, direct sunlight, freeze, humid and dusty location, etc.).
• Make sure that the floor where you install the appliance is flat, stable, heat resistant and
clean.
• Access to the service area is limited to persons with the necessary knowledge of safety
and hygiene as well as practical experience of the device.
• Leave enough free space around the appliance to facilitate its use and to preform any
maintenance operations.
A.6 Water connection
• The plumbing connections must be carried out by a specialised personnel.
• The machine is to be connected to the water mains using the new supplied hose-sets.
Do not use old hose sets.
• Always use a new set of joints if you remove and re-install the water inlet pipe to the
machine.
• Before connection to new pipes, pipes not used for a long time, where repair work has
been carried out or new devices fitted (water meters, etc.), let the water flow until it is
clean and clear.
• The dynamic water pressure (minimum and maximum) must be between:
– 1 bar [0.1 MPa] and 8 bar [0.8 MPa];
• Make sure that there are no visible water leaks during and after the first use of the
machine.
• Install an approved dual check valve upstream according to the regulation of the
installation country.
A.7 Electrical connection
• Work on the electrical systems must only be carried out by a specialised personnel.
• Make sure that the electrical information on the rating plate agrees with the power supply.
• Make sure to install the appliance in accordance with the safety regulations and local
laws of the country where used.
• If the power cable is damaged it must be replaced by the Customer Care Service or in
any case by specialised personnel, in order to prevent any risk.
• The appliance must be correctly earthed. The manufacturer is not responsible for the
consequences of an inadequate earthing system.
• To protect the power supply of the appliance against short circuits and/or overloads,
install a thermal fuse or a suitable automatic thermal magnetic circuit breaker, ADS
(Automatic Disconnection of Supply).
• To protect the power supply of the appliance against current leakages, install a high-
sensitivity manual reset RCD (Residual Current Device), suitable for overvoltage
category III.
For protection against indirect contacts, refer to point 6.3.3 of EN 60204-1 (IEC 60204-1)
with the use of protection devices that ensure automatic cut-off of the supply in case of

10
isolation fault in the TN or TT systems or, for IT systems, the use of isolation controllers
or differential current protection devices to activate automatic power disconnection (an
isolation controller must be provided for indicating a possible first earth fault of a live part,
unless a protection device is supplied for switching off the power in case of a such a fault.
This device must activate an acoustic and/or visual signal which must continue for the
entire duration of the fault). For example: in a TT system, a residual current device with
cut-in current (e.g. 30 mA) coordinated with the earthing system of the building where
the appliance is located must be installed ahead of the supply.
A.8 Use
• The appliance must be used in room with an ambient temperature of 5℃to 35℃(41℉-
95℉).
• If it is stored at an ambient temperature below 5℃(41℉) the water circuit (boiler-piping)
must be drained.
• In case of emergency (fire, surge, abnormal noise, etc. the first thing to do is to cut off the
current and close the water tap.
• Make sure not to obstruct the air inlets of the appliance with towels or other objects.
• Beware of hot surfaces such as cup heaters, the unit heads and the hot water and steam
outputs. Never install containers filled with liquid on the top of the appliance.
A.9 appliance cleaning and maintenance
• Refer to “A.3 Personal protection equipment“ for suitable personal protection equipment.
• Put the appliance in safe conditions before starting any maintenance operation.
Disconnect the appliance from the power supply and carefully unplug the power supply
cable, if present.
• Depending on the model and type of electric connection, during maintenance operations,
the cable and plug must be kept in a visible position by the operator carrying out the work.
• Do not touch the appliance with wet hands or feet or when barefoot.
• Do not remove the safety guards.
• Respect the requirements for the various routine and extraordinary maintenance
operations. Non compliance with the instructions can create risks for personnel.
• Extraordinary maintenance, checking and overhaul operations must only be carried out
by a specialised personnel or the Customer Care Service, provided with suitable
personal protection equipment (safety shoes and gloves), tools and ancillary means.
• Do not clean the appliance with jets of water.
Repair and extraordinary maintenance
• Repair and extraordinary maintenance have to be carried out by specialised authorised
personnel. The manufacturer declines any liability for any failure or damage caused by
the intervention of an unauthorized technician by the Manufacturer and the original
manufacturer warranty will be invalidated.
• The appliance should be descaled only by a specialised personnel.
• Do not forget to regenerate your water softener periodically.
A.10 Service
• Only original spare parts can ensure the safety standards of the appliance.
A.11 Disposal of packing
