Whirlpool AFO ED4DS Instrucciones Para La Instalación página 13

When the appliance is operating, the power supply voltage must not diverge from the value of the nominal voltage,
indicated on the data plate, by more than ± 10 %.
Insert the plug in the socket only if you are sure that the socket is right for the plug. Three phases ovens are not
supplied with electrical cable, therefore it is necessary to connect to the oven internal terminal board a cable of
proportionate section.
Cable replacement: after opening the lower cover, placed in back side of the oven (unscrew the fixing screw), con-
nect the conductives in accordance with the selected wiring diagram.
Fix the cable to the suitable cable gland and close the back cover.
The connection and the creation of the cable has to be done by authorized personnel.
If the cable is damaged it has to be sustituted by authorized personnel.
1.7A EQUIPOTENTIAL SYMBOL
Equipotential connection is necessary when different appliances have to be connected (electrical or
neutral) in an equipotential system.
1.8 WATER FEATURES
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 auto-
matically invalidate the guarantee.The use of dosing systems designed to prevent the build-up of lime-scale in
pipes (i.e. polyphosphate dosing systems) is also prohibited since it may impair the performance of the appliance.
1.9 GAS CONNECTION
The section of the enter gas tube depends on the gas type and on the consumption of the installed oven.
The connection must be done according to the current local regulations.
The gas oven is equipped with a ½" male thread positioned in the back side of the oven (see the drawing below).
The connection has to be done with fitting adapters and gaskets appropriate for the used gas type (see technical
data). A fast acting shutoff valve must be installed on the gas inlet line to the oven.
The valve must be type test approved according to the current regulations. The connections of the gas main can
be permanent or detachable; if flexible metal tube is used, this should be made of stainless and corrosion resistant
material (do not use rubber hose!). Every type of chosen sealing material used for connections have to be tested
and approved for this purpose. All connections between the mains and the appliance must be tested for leakage.
The recommended method is to use a proprietary leak detection spray or a non-corrosive foamy liquid of any gen-
eral description can simply be brushed onto the fittings: the important thing is that NO BUBBLES SHOULD APPEAR.
WARNING: NEVER ANY CIRCUMSTANCES TEST FOR GAS LEAKS WITH A NAKED FLAME.
