Water supply for oven’s steam generators does not have to exceed 12°F total hardness (French degrees),
6.5 dH (German degrees) or 8.4° (Clark degrees).
Using softeners with ion exchange resins reduce temporary water’s hardness but, at the same time, lowers
the Ph. Ph values inferior to 7 indicate acidic and therefore corrosive water. Acidity can be neutralized by
added polyphosphates through proper dispensers. It’s recommended to have the water analyzed by skilled
technicians, to avoid damages to the steam generators and the hydraulic plant.
11.2.1. ELECTRIC POWER
The power connection is in the rear wall of the oven (Terminal Board).
The electricity supply must have a functioning earth in compliance with the electrical legislation in force in the
country concerned: it the responsibility of the purchaser.
It is advisable to install a cut-out box with terminal board (consult with a specialized technician) on the power
supply (also provided with a master switch with protection fuses or magnetothermal switch), to which you
must connect all electric cables of chambers, provers and hoods.
The provisions of current legislation should be observed while making the electrical connection.
The connection to the electrical switchboard must be made by a qualified electrician.
For connection of the electric box and the power supply, use an IEC standard cable of sufficient thickness for
the oven’s power intake and other electrical features.
The electrical connection and the equipment required for it are the responsibility of the purchaser: the work
must be done by a qualified technician.
11.2.2. WATER (only for baking chambers provided with steam generator)
• Connection position on the back wall of the chambers, the provers or the hoods
• Pipes diameter ½ gas or equivalent internal section;
• ¾” gas joint for connection to the Electrovalve
• Provide gate valve for rapid closing
• Where water is particularly hard (high limestone concentrations) a water-softener should be
provided to prevent limescale deposits and damage to the vaporizing equipment as well as
to ensure better results from the product.
• Where water is particularly hard or salmastre (high clorure concentrations) prevedere

della vaporiera
• In the event of sudden pressure changes an appropriate pressure regulator should be fitted
• Minimum pressure with closed circuit: 2,5 atm.
11.2.3. STEAM CHIMNEY
• For evacuating excessive cooking steam
• For the materials and fittings to be used refer to the legislation in force in the country of
installation.
• A circular chimney certainly offers least resistance to the movement of fumes
• The draught depends on atmospheric conditions (humidity and temperature) and on altitude
(atmospheric pressure).
• The chimney must always be in depression with natural draw or an adequately forced draw .
• Chimney diameter for all models: 100 mm.
11.3.
OPERATIONAL TESTING OF OVEN
• Check that all connections have been properly made.
• Ensure that the power supply voltage corresponds to that on the oven label.
• Check that the probes (in the baking chambers) of thermostats have been properly fitted into
their places
