Open the power supply terminal board and insert the
jumpers provided as follows: one jumper between termi-
nals 2 and 4 and another between terminals 4 and 6.
Using a suitable power supply cable (see technical data
table), connect the three phases to terminals 1, 3 and 5,
the neutral to terminal 6 and the earth wire to the termi-
nal
.

Open the power supply terminal board and insert the
jumpers provided as follows: one jumper between termi-
nals 1 and 2, one between terminals 3 and 4 and
another between terminals 5 and 6. Using a suitable
power supply cable (see technical data table), connect
the three phases to terminals 1, 3 and 5 and the earth
wire to the terminal
.
Power supply 220...240V 1N
ATTENTION
Reduce the power of the boiler from 12 kW to 6kW
by connecting the resistors as shown in the circuit
diagram.
Figure 11
Open the power supply terminal board and insert the
jumpers provided as follows: two jumpers between ter-
minals 1, 3, 5 and another two between terminals 2, 4
and 6. Using a suitable power supply cable (see techni-
8
cal data table), connect the phase and neutral to termi-
nals 5 and 6 respectively and the earth wire to the
terminal
.
Connections provided for energy control
This appliance is designed for an external energy con-
sumption control.

Figure 12
Connect the energy peak controller across terminals
11 and 12.
CAUTION
!
A normally open (n.o.) contact of the
controller must be connected across
terminals 11 and 12. When this contact
closes the boiler heating elements are
disconnected. Using the dishwasher in
these conditions may increase the cycle
time.
Safety devices
•
An automatic reset thermal over-heat device incor-
porated in the windings of the electric pump cuts off
the electricity supply in the case of malfunctioning.
•
In the event of water mains failure, a device pre-
vents water in the boiler from returning into the
mains.
•
An overflow pipe, connected to the drainage outlet,
maintains the water in the tank at a constant level.
Failure to comply with safety rules and regulations
relieves the manufacturer of all liability.
