8. CONNECTION SPECIFICATIONS
Connection parts supplied together with the
machine:
•
Inlet water connection pipe: 3/4 female
connection.
•
Outlet water pipe: reinforced 13mm
rubber hose.
•
Screw fixing band to fix the hot water
discharge pipe.
- Supplied water inlet under the frame, near the
back side (see figure 4): ¾ male connection.
- Hot water outlet under the frame, near the
back side (see figure 4): reinforced rubber pipe,
14mm diameter barb connection.
- Along the water inlet line, before the slush
machine, it is recommended to insert a tap.
-
The inlet water pressure has to be
between 2 and 2,5 bars
; in case the water
pressure from the main is higher than 2.5 is
necessary to insert a pressure regulator set into
this range.
-
Minimum inlet water pressure: 1 bar.
- As discharge pipe it is necessary to use a
reinforced rubber hose or a rigid one; avoid any
bottleneck along the discharge pipe and make
sure it is discharging without obstruction. Do
not use any kind of pipe that, considering more
or less an outlet temperature of 50°C, could
result deformed or damaged creating some
obstacles to the water exit. This could force the
intervention of the HP pressure switch stopping
the machine functioning.
- In case of lack of water, low water flow rate or
low water pressure along the line, the safety
pressure switch will stop the refrigerating
system functioning and the red light will light on
the machine control panel; only the compressor
will be stopped while all the other machine
functionalities will continue operating (chapter
10).
In this case, it is necessary to check for the
water along the line, push the red button under
the frame under the control panel and the
refrigerating system will start operating again.
- In case of frequent pressure switch
interventions , before pushing the red switch in
order to re-activate it, check for the water
presence along the inlet line and for the
discharge pipe to be free from obstacles.
NOTE: the frequent switch intervention with the
following reactivation without having defined the
root cause of this behaviour, could strongly
reduce the compressor life.
