3.2 CONNECTION TO THE ELECTRICAL SUPPLY
MAINS
1. Ovens equipped with cable and Schuko plug (single
phase 230V): it is sufficient to plug in the equipment
to the appropriate outlet (the outlet must be suitable
to the issued plug)
2. Ovens equipped with cable (three-phase 400V +
neutral): the issued cable is with 5 wires, therefore
it has to be connected directly to an electric board
or suitable outlet. To make different connections it
is necessary to replace the cable with the correct
one on the basis of the information indicated in the
attached file "Technical Data". You find the connec-
tion schemes on internal side of the terminal board
cover.
The replacement of the cable must be done by au-
thorised personnel.
To replace the cable proceed as follows:
• Open the terminal board cover by unscrewing the fix-
ing screw
• Connect the wires according to the chosen connec-
tion scheme
• Fix the connecting cable through the proper cable
fastener
• Close the terminal board cover and tighten the fixing
screw
WARNING:
Connect the electrical cable to the terminal board as
shown on the drawing: insert the copper bridge and the
electrical cable together under the screw. Tighten the
screw paying attention that the cable and the copper
bridge are well fixed under the screw.
A wrong connection can cause the overheating and
the melting of the terminal board.
The appliance must be connected to the ground
line of the network.

3.3 EQUIPOTENTIAL SYSTEM
The appliance must be included in an equipotential system
whose efficiency must be properly checked according to
the current laws. This connection must be done between
different appliances through the terminal marked with
the symbol: simbolo morsetto equipotenziale
The equipotential conductor must have a minimum sec-
tion of 10 mm .

4. WATER CONNECTION
4.1 WARNING
It is necessary to place a mechanical filter and a shut-off
valve between the water system and the appliance.
As required by current laws, the appliance is equipped
with 2 metres of pipe, the respective pipe fitting (3/4")
with non-return valve and mechanical filter.
Before connecting the water pipe to the appliance please
let some water flow to clear the pipe of any obstruc-
tions.
The water used in the appliance must have a pressure
value between 1 and 3 bar and a maximum temperature
of 30°C.
4.2 TREATMENT OF WATER
The water must have a maximum hardness of 5 °FH (this
avoids formation of limestone inside the chamber of the
oven).
It is strongly recommended to use a demineralising appli-
ance (reverse osmosis unit) in order to avoid limestone
and/or other minerals depositing inside the oven.
The UNOX reverse osmosis system, code XC224 is avail-
able for this purpose. This system is directly controlled
by the control board of the oven through a self•diagnosis
system.
