7. CONNECTIONS

THE MANUFACTURERS DECLINE ALL
RESPONSIBILITY IF STANDARD SAFETY
NORMS ARE NOT COMPLIED WITH.
The position and dimensions of connections are
given in the installation diagram at the end of this
manual.
ELECTRICAL CONNECTIONS
ATTENTION: THE USE OF ADAPTORS,
MULTIPLE SOCKETS OR EXTENSION
CABLES IS STRICTLY FORBIDDEN.
Check that the appliance is designed to operate at
the voltage and frequency of the power supply
present on site. Check the details given on the
appliance dataplate.
Install upstream of the equipment in an easily
accessible place, an all-pole disconnecting device
with a contact gap of allowing full disconnection
under the conditions of overvoltage category III.
A flexible rubber cable with insulation specifications
not lower than type H05 RN-F must be used for
connection.
Connect the power supply cable to the terminal
board as shown in the wiring diagram supplied with
the appliance.
Secure the power supply cable with the cable
clamp.
Protect the power supply cable on the outside of
the appliance with a rigid plastic or metal pipe.
PROTECTIVE
EARTH
AND
CONNECTIONS
Connect the appliance to an efficient ground circuit.

The appliance must be connected to its water
supply with a flexible hose. A shut off valve (cock)
must be installed between the water supply line
and the appliance's solenoid valve. The cock must
be close to the appliance.
The water supply minimum pressure, measured
when water enters the machine during the final
rinse (flux pressure), should not be lower than 2
bar, even in the presence of other open taps on the
same line.
We recommend that each machine is equipped with
its own pipe having reduced length and a
sufficiently large cross section so as to avoid
pressure or load losses.
An additional rinsing pump, available as an optional
item, must be installed in cases where pressure is
lower than the minimum value required (see tab. 2)
A pressure reducing valve must be installed
upstream from the supply pipe in cases where static
pressure is greater than 5 bar. The supply pipe of
the machine must have a capacity equal or greater
than 20 lt/min.
Once the appliance has been installed, check for gas
leaks at the connection points.
The equipment must be connected to the water
supply through the use of a new set of tubes.
CONNECTION TO THE WATER DRAIN
DO NOT INSTALL THE OUTLET HOSE IN
TUBS, SINKS ETC.
The water drainage system must be made using
materials resistant to temperatures of 100 °C. The
bottom of the appliance must not be subjected to
steam produced by drainage of hot water.
The drain hose must be connected directly to the
drain duct after a siphon has been interposed.
The hose must be able to reach the sump without
stretching, restriction, folding, crushing, pressing or
forcing in any way.
THE TUB DRAINS UNDER GRAVITY, SO
THE DRAIN SUMP MUST BE LOWER
THAN THE MACHINE'S BASE.
if the drain is not lower than the base of the
appliance, you can use the version with drain pump
(available on request).
IN THIS CASE, THE DRAIN
CONNECTION MAY BE NO HIGHER
THAN 1 M. ALWAYS CHECK THAT THE
DRAIN WORKS PROPERLY AND IS NOT
BLOCKED.
