• The disposal of packaging parts must be carried out in accordance with the standards of the
country in which the machine is installed.
Plastic packaging must not be discarded in the environment.
• After having unpacked the machine, make sure it is intact. Also, check that the identification
plate and warning signs are present and legible.
If in doubt, do not use the machine and contact a QUALIFIED TECHNICIAN.
• The machine is not intended to be connected to the potable water mains.
If you want to connect the machine to the potable water mains, you must use a backflow
prevention device, in accordance with EN 60335-2-79 (available from your retailer).
Operations such as water tank suctioning can be performed without backflow preventer.
• WARNING. Water that has flowed through the backflow preventer is considered to be non-
potable.
• The electric supply connection shall be made by a qualified electrician and comply
with IEC 60364-1.
It is recommended that the electric supply of this machine should include either a residual
current device that can interrupt the supply if the leakage current to earth exceeds 30 mA
for 30 ms or a device which can test the earth circuit.
• A QUALIFIED ELECTRICIAN must carry out the following:
- Check that the power supply system is in accordance with the data indicated on the
identification plate: the voltage should not vary by more than ± 5 %;
- If the power supply cable is not available and if the device is not to be connected in a fixed
manner to the power supply, fit a plug in compliance with the standard of the country in
which the machine is installed;
- Check that the power socket the machine is plugged into is fitted with a suitable fuse (the
value is indicated on the identification plate and on the Technical data chart).
• If a fixed appliance is not fitted with a supply cord and a plug, or with other device ensuring
omnipolar disconnection from the mains, with a contact separation in all poles that allows
full disconnection under overvoltage category III conditions, these disconnection devices
must be incorporated in the supply mains in accordance with the installation rules.
NOTE: in the instruction manuals, the machine is always intended as being connected to the
mains power supply by means of a plug. If the machine is permanently connected in a fixed
manner to the power supply, it is intended that:
- having the disconnection device from the supply mains in the off position ("0") and its
actuator locked with a padlock or similar means is the same as having the plug disconnected
from its mains power supply socket;
- having means for disconnection from the supply mains in the on position (position "1") is
the same as having the plug connected to the mains power socket.
• If the power supply cable is too short, an extension cord can be used, following the instructions
given in the following table:
