sued on 25 July 2005, nr 151 ”Implementation of the directives 2002/95/CE, 2002/96/CE e 2003/108/CE, concerning the decrease in the usage
of dangerous substances in the electrical and electronic equipment and the disposal of waste”.
The symbol of the crossed waste bin indicated on the equipment or on the packaging means that the product at the end of its lifetime must
be disposed of separately from all the other waste.
The separate collection of this equipment coming at the end of its lifetime is organized and run by the importer/distributor. The user who
should have to dispose of such equipment should get in touch with the importer/ distributor and follow the procedure they have adopted for
the separate disposal of the equipment coming at the end of its lifetime. The proper separate disposal of disused equipment so that it can
be recycled and treated according what is environmentally compatible contributes to avoid possible negative effects on the Environment and
on Health and allows the reutilization and/or the recycling of the materials the equipment is composed.
The improper disposal by the user causes the enforcement of the administrative sanctions according to current regulations.

Danger!
INSTALLATION OF THE WATER SOFTENER IS RECOMMENDED TO PROLONG THE LIFE OF THE MACHINE.
Before installing the machine, check the hardness of the water and t a softener based on the instructions of the manufacturer
and to standards and regulations in force.
Proceed to programme the automatic and/or volumetric softeners according to the manufacturer’s instructions.
Danger!
If a water softener is not a part of the water system, it is necessary to apply a lter to the inlet hose of the motor pump to avoid
the entry of impurities that could damage the motor pump or the machine.
Attention!
The motor pump must be installed at a distance to avoid drips or spurts of water and also to avoid salt from dropping onto the
motor pump when lling the water softener with salt.
Before connecting the hose coming from the motor pump or from the water-softener, in case of appliances with built-in
pumps, place it in a bucket and turn on the water tap (1- Fig. 5) for a couple of minutes in order to eliminate possible residues
from the new hoses and in any case, until the water ows clear.
4.3 DRAINAGE SYSTEM
Assemble the push-t drainage hose in the appropriate rubber holder of the collection basin of the machine and place the other end of
the hose directly into the drainage u-pipe of the prearranged drainage system.
Check that the hose is not blocked or crushed along its length and it also has a sufcient incline to be able to drain without difculty.
Danger!
Do not place the drainage hose in basins or buckets underneath the counter to avoid the possibility of creating receptacles of
dirt with the consequent proliferation of bacteria.
