- Connect the cold and purified (if available) water
hoses, exiting the machine with their respective
network connections, as shown on the installation
diagram. It will be the responsibility of the installer
to make sure that the temperature of the cold
water supply is not higher than 5/15°C, otherwise
proper washing of materials cannot be ensured. The
connections for cold and purified water must not feed
any equipment other than the instruments washer.
During the washing cycle, this is necessary to prevent
the subdivision of the water supply with other users,
thus leading to a substantial increase in the time
required to fill the tank (in this case an alarm will be
triggered to alert the user that the maximum time
allowed for water loading is exceeded).
- If the machine is provided with a purified water
feeding system but the plant is not equipped with
it, the cold and purified water hoses should be
connected together.
- The machine can be equipped with a built-in softener,
which has the function of reducing the scale in the
water supplied
- Connect the flexible hoses to the machine valves
positioned in view at the back, making sure to connect
them correctly based on the sales configuration.
- Make sure to connect the water flexible hoses in the
positions shown in figure 8.
- Connect the cold water flexible hose to connection
1 in figure 8.
- Connect the purified water flexible hose (if any), to
connection 4 in figure 8.
a
WARNING. The flow pipes must not be
shortened or damaged.
The water supply taps must be capable of quickly
stopping the water line, therefore, they must be
equipped with a ball or a gate valve. They must also
withstand the operating pressure of the water, as
indicated in the technical data sheet.
The installer must check the water hardness which
must be 0.7 mmol/l (4 °dH). Possibly use a softener.

Proper placement of the taps is shown on the device
installation drawing that can be downloaded from the
manufacturer’s website.
Models with built-in water softener
The integrated function of the softener is used to
reduce the amount of limescale contained in the
incoming water. If the machine is connected with hard
water, the result is a rapid degeneration with loss of
function and performance.
Regeneration must be performed to keep the ionic
resins active.
For machines equipped with a water softener, when
installed, it is necessary to enter the water hardness
value by entering in programming menu.

WARNING. During this operation, check that
the plastic cap is closed.
Insert the basket and start a normal washing cycle. The
machine regenerates automatically.
