Appliances are intended to be permanently connected to the water mains.
WATER PRESSURE
La pressione dell’acqua nella rete deve essere compresa fra 200 e 500 kPa, come già riportato nel capitolo “Dati tecnici”. Qualora la pressione fosse superiore, interporre a monte dell’apparecchio un riduttore di pressione.
WATER HOOKUP TO SUPPLY THE STEAM GENERATOR (IF PRESENT) AND VAPORIZER
The water supplied to the vaporizer must be either cold and softened, or hot
(max 50 °C), as described below. The water connection is R 3/4”. The hose for connection to the water supply must be provided by the installer. The water hose must be provided by the installer and must be in compliance to IEC 61770. Do not reuse pre-existing or used hoses. A shutoff valve must be installed on the line between the oven and the supply.
The connection to the water supply is located at the right rear of the bottom of the appliance.
WATER SPECIFICATIONS
The characteristics of the water must come within the limits given below, in order to prevent both corrosion, which is extremely damaging for the appliance, due to supplying water that is too softened or too aggressive, and scaling in the oven and in the water system in the case of supplying water that is too hard.
Hardness: between 6° and 9° fH
PH: greater than 7.5
Chlorides: less than 30 ppm
These values are important for ensuring that the water used by the appliance is suitably treated!
It is advisable not to use a treatment system that causes carbonate hardness less than 6 °fH as water having these characteristics may be aggressive and corrosive, thus shortening the service life of the appliance.
UK only:
WRAS approval IRN 160. To be carried out by the installer: An approved double check valve or some other no less effective backflow prevention device shall be fitted at the point of connection between the supply and the fitting.
The use of sodium ion exchangers (commonly known also as salt softener) is not recommended.
WATER CONNECTION FOR STEAM CONDENSATION
Cold water must be hooked up for steam condensation. The water attachment is R 3/4”. The water hose must be provided by the installer and must be in compliance to IEC 61770. Do not reuse pre-existing or used hoses. A water shut-off valve must be installed upstream of the oven.
It is advisable not to use a treatment system that causes carbonate hardness less than 6 °fH as water having these characteristics may be aggressive and corrosive, thus shortening the service life of the appliance.
