HOT WATER CONNECTION (B
RED – IF REQUIRED
)
A water valve has to be provided in an easily accessible position, to which the inlet filter has to
be connected. For dimensions of the valve please refer to installation drawing.
Strictly observe the national and regional water board regulations in force.
The dynamic pressure must not be less than 2 bar and not more than 4 bar (200/400 kPa). A
good result can be obtained if the incoming water has a hardness not exceeding 5/7°Clarke and
a temperature of 55°C-0+10°C.
For appliances connected to the water mains by detachable hose-sets, a new hose-sets are to be
used and the old hose-sets should not be reused.
The correct quantity of rinse water is regulated by the flow ristrictor of solenoid valve Y10.
COLD WATER CONNECTION (D
BLUE - IF REQUIRED
)
A water valve has to be provided in an easily accessible position, to which the inlet filter has to
be connected. For dimensions of same please refer to installation drawing. Strictly observe the
national and regional water board regulations in force. The working pressure must not be less
than 2 bar and not more than 4 bar (200/400 kPa).
For appliances connected to the water mains by detachable hose-sets, a new hose-sets are to be
used and the old hose-sets should not be reused.
Only for machines steam energy recovery unit, for obtaining a good result the incoming water
should have a hardness not exceeding 5/7°Clarke.
STEAM CONNECTION (E)
(only for steam heated machines)
The supply of steam and connections to the machine must be in accordance with the
installation drawing. In order to isolate the machine from the general steam supply network it is
essential to provided a local isolating valve of 1” BSP.
The minimum pressure for the steam supply is 0,5 bar (50kPa-110,8°C) and the maximum
pressure is 1,5 bar (150 kPa-127°C). If especially requested in the order the maximum pressure
can reach also 3bar (300 kPa - 143°C). The steam must be absolutely saturated and dry.
WATER DRAIN (A)
A floor drain with a waste trap has to be provided for connection to the machine, make sure
that there are no restrictions in the waste service. Any materials used on the installation must
withstand a temperature of 70°C. Strictly observe the national or regional water board
regulations relating to water discharges.
STEAM DISCHARGE (F)
(only for steam heated machines)
The discharge of the steam condensate must have a suitable inclination towards the recovery
system or recirculation pump which guarantees the automatic removal of the condensate.
