COLD WATER CONNECTION (SOFTENED)
Water pressure min.

bar)
. The water inlets (Fig.1 Pos. A) must be connected to the
diluted feeding system at a max. temperature of 50°C through
shut-off cocks, to be closed when the equipment is not working
or during maintenance operations.
The water is used to supply the humidifier.
Between the shut-off valve and the pipe hooking up with the
oven, there must be a mechanical filter so as to prevent any
ferrous waste getting inside that could over time cause
oxidation of the oven.
If the hardness of the water is greater than
5-7°Fr
, it is necessary
to install a softener with automatic regeneration, to be
positioned after the mechanical filter. As regards the flow rate
per hour of the softener, refer to the Table I.
2.5
WASTE WATER OUTLET
The water discharge (Fig.2 Pos. A) must be conveyed to a drain-
trap (Fig. 1.2 Pos. B) according to the local sanitary standards
in force.
The discharge duct must be made of materials resistant to
100°C temperature.
We recommend placing an open relief pipe
(Fig.2 Pos. C) between the water discharge coming from the
oven and the drain-trap, ca. 1 meter in height, in such a way as
to foster the water down flow.
The oven is designed to direct the discharge of the black water
on the left side and on the rear (Fig.2 Pos. D).
N.B. “Closed” connection to the channel is NOT allowed!
