- Air-cooled machines have a fan (R) which is controlled by the pressostat (F).
- In water-cooled models without pressostatic valve, pressostat (J) opens and closes
the condenser electrovalve (K).
- Evaporator temperature decreases until the cycle thermostat (T2) set point is
reached, at this temperature circuit 1-2 will be closed and timer motor (G) will switch on.
- Once the cycle is over, the pins on the timer wheels will force the micros to change
circuits, stopping the pump and opening the hot gas valve and water valve. The combined
effect of hot gas and water sprayed on the top of the evaporator will release the ice cubes
and change the position of the cycle thermostat (T2).
- The ice production and defrosting cycle will continue until the ice storage bin is full, at
which point cycle thermostat (T1) will disconnect the machine, but never during a cycle, but
at the beginning of the defrosting stage, since during the production cycle, current will
reach the pump via terminals 1-2 of micro G1.
- The machine will remain disconnected until the level of ice in the bin drops below the
thermostat because of ice consumption. At this point the bin thermostat T1 changes and
the machine will start a new production cycle automatically.
