8.1 • WATER PRESSURE
The pressure of the water in the network
must be between 200 and 500 kPa,
(30 - 72 psi) as already stated under the
heading “Table 2: General Water Data”. If
the supply pressure is higher than this, a
pressure reduction valve must be installed
between the oven and the main.
8.2 • WATER CONNECTION TO THE
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. A shutoff valve
must be installed on the line between the
oven and the supply.
8.3 • 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 60 and 90ppm
PH: greater then 7.5
Chlorides less than 30ppm
These values are important in ensuring that
the water used by the appliance is suitably
treated!
8.4 • DRAIN
It is imperative to fit a drain cup to ensure
a minimum air drop of 25mm. between
the appliance’s plastic drain elbow and
drain line. A direct connection is not
permissible.
WARNING:
The drain line must be outside the
perimeter of the oven.
It is prohibited to reduce the diameter
of the drain pipe shown in the
installation diagram.
