The following diagram shows the main concepts of the hydraulic
circuit:
Evaporator

Water
Condenser
Spray-bar
Pump
Overflow tube
Water Basin
CB1565 ONLY
Pressostatic
Valve
The water supply circuit of the basin, the water-inlet valve, the
pump and the evaporator are on all machines of the ‘CB’-line;
the water condenser circuit, on the contrary, is on water-cooled
versions only.
Water-inlet valve
It works during the defrosting phase and allows the water to flow
on the evaporator, having two goals: 1
st
. one is to warm the
evaporator help, in this way, the ice cubes detaching; 2
nd
. one,
the water falls into the basin, restores the ideal level to start a
new production cycle.
The second water-inlet valve allows the water flow of the
through the water condenser.
Water basin
It gets water from the water mains. It feeds the pump by a
specific pipe provided with a filter.
Pump
It draws out water from the water basin and pipes it, under
pressure, to the spray-bar.
Spray-bar
It gets water from the pump and, by means of its nozzles,
sprays it towards the cubes basin of the evaporator. The water
that does not freeze, by contacting the cups (refrigerated by the
evaporator coil), falls in the inside bin and is drawn by the pump
once again.
Overflow tube
It is a floodway. All the surplus water, entering into the water
basin, comes out from it.
Pressostatic valve (CB1565 only)
It is assembled only on water cooled machines.
It controls and keeps constant the condensing pressure, by
changing the quantity of water that flows in the condenser.
