1.7 WATER INSTALLATION
It is very important that feedwater to the oven be demineralized.
The place where the oven is to be installed must have a water intake on which a constant water
pressure of 1,5 kg/cm
2
is assured during a steam injection by means of a pressure regulator device.
The connection between this connector and the oven will be by flexible hose-pipe of an inner
diameter of 10 mm (0.4 inc.)..
NOTE
:
For those cases in which water is calcareous, it is necessary to install a water softener between
the
water supply and the oven intake. (
Not supplied with the oven
)
Fitting of the water softener decalcifier is shown in the following drawing.
A -
Water intake from mains.
B -
Water input to oven.
C -
Drain-off from water softener.
1 -
Water softener.
2 -
Pressure regulator.
3 -
3/8" manual valve.
4 -
Couple hose, 3/8".
5 -
Coupling hose.
If a connection between point
B
(water softener outlet,
Fig. ka0021c0.ei1
) and point
D
(oven water
intake
Fig. vistatra.dft,
see point 2.1), is desired, this must be done with 3/8 “ diameter hose leaving at
both ends a 1/2 “ male pipe.
1.8 DRAIN (OPTIONAL)
It is necessary to construct a drain of diameter at least 1". This should preferably be made of metal and
should be temperature-resistant in any case. It will be coupled to the oven by a flexible hose of internal
diameter 18 mm, washing-machine type.
