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.

8
• 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 appliance is only to be installed in locations where its use and maintenance is
restricted to trained 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, water jet or slashing and dusty
location, etc.).
• The appliance is not suitable for installation in an area where a water jet could be used.
• The floor where you install the appliance has to be a horizontal plane, 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.
• Before connecting the power and water supplies, check that the electrical and water
network are in accordance with the technical information plate of the device.
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 appliance must be install with a new softener.
• The dynamic water pressure (minimum and maximum) must be between:
– 1 bar [0.1 MPa] and 10 bar [1 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.
• At the end of the service or in case of prolonged absence cut off the water by the general
tap.
A.7 Electrical connection
• Do not disconnect or modify the security elements in the appliance, the manufacturer is
not responsible for the consequences of an inadequate using system.
• 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.

9
• 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
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.
• The power supply must be provided with the following safety features: power switch
which completely isolates the machine from the mains (gap between contacts of at least
3 mm), efficient earthing and an effective circuit breaker for protection against earthing
leaks; section of the conductors appropriate for a power capacity.
IMPORTANT
At the end of the service or in case of prolonged absence cut off the appliance
by the general switch.
A.8 Use
