1.7 ELECTRICAL CONNECTION
When the appliance is delivered it is set to work at the voltage given on the rating plate affixed on the right side of
the appliance.
The effectiveness of the equipotential system of which the appliance is part of, must conform to current standards.
Connect using the screw you find in the back side of the oven, marked with the word
EQUIPOTENTIAL
.
The Manufacturer declines all and every responsibility if this important accident prevention norm is not complied with.
If the feeding cable is damaged, it must be replaced by the technical service or in any case by similar qualified per
-
sonnel, in order to avoid any risk.
2.5 HYDRAULIC CONNECTION – WATER INLET
If the manual humidification system (optional) is installed, the ovens have a water inlet coupling at the back.
Always install an on-off valve between the appliance and the water mains, making sure it is easy to operate.
We also suggest installing a cartridge filter on the water inlet pipe.
Always use a set of new water joints, eventual old joints must not be used again.
Plumbing connection must be always effected with cold water and rigid pipes.
Never use hoses to connect the oven to the water main.
The water must be suitable to human use with the following characteristics:
Temperature
: included between 15 – 20°C
Total hardness
: included between 4 and 12 °f (French degrees), it is advisable to install a softener upstream from
the appliance that will maintain the hardness level at the mentioned values.
Pressure
: included between 150 and 250 KPa (1,5 – 2,5 bar).
Attention: higher water pressure values result in increased water consumption and can compromise the
correct functioning of some components.
Maximum chloride concentration
(Cl-): less than 150 mg/litre.
Chlorine concentration
(Cl2): less than 0.2 mg/litre.
pH
: more than 7.
Water conductivity
: included between 50 and 2000 µS/cm.
Attention: Water treatment systems that bring to different values to the ones above mentioned automatically
invalidate the guarantee.
The use of dosing systems designed to prevent the build-up of lime-scale in pipes (i.e. polyphosphate dosing sys
-
tems) is also prohibited since it may impair the performance of the appliance.
