IG, Fig. 3/Fig. 4
First insert the power cable through the packing gland
SR (Fig. 3/Fig. 4
) and connect it to the connection
strip
PS (Fig. 3/Fig. 4
) as shown in
Fig. 9
and
Table 1
.
The power cable must be secured using the packing glands
SR (Fig. 3/Fig. 4
).
It is also possible to complete the electrical connection of the detergent / rinse aid dispensers and/or the limit
micro switch (please refer to the corresponding chapter).
By default, the appliance is configured for alternate heating (
Fig. 10
). If simultaneous heating is required
(simultaneous heating of the boiler and the wash tank), this change must be reflected in
Fig. 11
(connection
specifications in
Fig. 9
and
Table 1
) (please refer to corresponding chapter).
On completion of the electrical installation, replace and fasten the covers.

Hydraulic connection
Before connecting the machine to the mains water supply, the water must be tested and should comply
with the following requirements:
pH
6.5
– 7.5
Total hardness
of the water:
5
– 10
⁰
fH (French degrees)
Impurities:
Ø < 0.08 mm
3.5
– 7
⁰
fH (English degrees)
Chlorides:
max. 150 mg/l
2.8
– 5.6
⁰
dH (German degrees)
Cl:
0.2
– 0.5 mg/l
50
– 100 mg CaCO3/l
Conductivity:
400
– 1,000 µS/cm
If the water quality does not meet the specified requirements, contact a professional able to advise on the
water treatment systems necessary to make the water suitable and to provide a solution.
If the water hardness is higher than that indicated, a descaler should be installed to prevent the build-up of
lime on the machine and to permit optimum cleaning and drying.
In addition to water quality, the pressure of the mains water supply must be considered. This is important
to ensure the machine operates correctly. The dynamic pressure of the water inlet must be within the values
indicated in the following table.
DYNAMIC PRESSURE OF WATER INLET
cycle
200 kPa
2 bar
2
kg/cm
2
29 psi
Max.
400 kPa
4 bar
4.1 kg/cm
2
58 psi
If the water pressure is higher than the recommended pressure, a pressure regulator must be mounted
(
Fig. 6)
. If it should not be connected as shown in
Fig. 6
but without the pressure reducer.
If the water pressure is lower than the recommended pressure, a pressure pump must be mounted (
Fig.
7)
. Please contact your supplier or the manufacturer to request the PRESSURE PUMP KIT.
If the mains pressure is within the values shown, the installation is as shown in
Fig. 5.
The temperature of the water entering the appliance is also important. Depending on the version purchased,
the appliance will be prepared to operate with cold water (CW) or hot water (HW). The required
temperatures are shown in the following table.
WATER INLET
TEMPERATURE
Cycle
Max.
Cold Water (CW version)
15 ºC / 59 ºF
50 ºC / 122 ºF
Hot Water (HW version)
50 ºC / 122 ºF
60 ºC / 140 ºF
