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
CONNECTIONS
Connect the appliance to an efficient ground circuit.
Connect the earth conductor to the terminal with the
symbol next to the main terminal board.
Connect the metal structure of the appliance to the
equipotential node. Connect the conductor to the
terminal with the symbol placed on the outside of
the rear panel.
CONNECTION TO THE WATER SUPPLY
Prior to connecting the machine to the power and
water supply check the general instructions and the
information indicated on the data plate by the
manufacturer.
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.
AND EARTH BONDING
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.

8. ADJUSTMENTS AND CHECKS

The following adjustment and setting operations may
be carried exclusively by qualified and authorised
personnel, paying the utmost care and attention, and
taking all precautions in the event that safety
features are bypassed.
