Functions of the unit

NOTICE!
Flowchart; see chapter 10.1
The three basic functions of the unit are:
– Refrigeration
– Carbonisation
– Conveying
All functions are controlled by the requests at the tower or by the sensor logic of the unit's internal control system.
The carbonator pump forces the mains water into the carbonator tank at a constant pressure.
The water in the carbonator tank has CO
the secondary refrigeration system to the tower.
Ice is built up in the water bath to refrigerate the products. The agitator keeps the products refrigerated. The ice build-up sensor
prevents excessive freezing of the ice build-up.
Cold generator
A cold generator refrigerates the water bath by means of a heat exchanger. In the process, a defined ice build-up is generated
around the heat exchanger.
To stop the water bath from freezing up and to maintain more efficient heat exchange, an agitator constantly agitates the cooling
water.
Once the unit has been filled with water, the refrigerant compressor automatically starts up after 3 minutes if the compressor is in
position "I". Once the maximum ice build-up has been achieved, the refrigerant compressor automatically switches off.
In ice build-up mode, certain minimum runtimes and operation intervals arise. After switching on the refrigeration circuit, the run-
time is at least 5 minutes, even if a shutdown has been signalled beforehand. After switching off the refrigeration circuit, the oper-
ation intervals are at least 3 minutes, even if switching on has been signalled beforehand. The operation intervals of 3 minutes
also apply to start-up or after a power failure.
Control system and sensor logic
There is a sensor for the water level in the carbonator tank, a probe for controlling the ice build-up, the hot gas probe for the re-
frigerating unit and an ambient temperature probe.
If CO pressure is insufficient in the carbonator tank, a yellow LED on the control unit will visually indicate that the pressure is too
2
low (< 0.4 MPa).
The tower power supply is cut off in good time to prevent the carbonator tank being pumped empty. Once the carbonator tank has
been refilled, the power supply is automatically switched on again.
If the fill level drops below the minimum, the carbonator pump will automatically switch on and fill the carbonator tank.
The carbonator pump switches off when the carbonator tank has been filled to maximum, or after 20 minutes at the latest. Longer
runtimes indicate leaks or excessive beverage dispensing. The pump can only be restarted by a reset (temporarily unplugging the
mains plug for approx. 10 seconds).
Water supply
The system's drinking water supply is provided by the mains water which flows through a pressure-reducing valve and filter to the
carbonator pump on the unit's connecting plate. If still water is requested at the tower, the water flows via a heat exchanger in the
refrigerated water bath to the tower.
To ensure the water stays chilled, even in the breaks between dispensing, a circulation pump in the unit constantly recirculates the
water via a heat exchanger in the water bath.
CO connection

ingredient for reduced calorie ('light') products.
Soda and still water connection
The soda is connected to the flow and return connections of the soda water circuit on the unit's connecting plate.
Still water is connected at the unit's still water outlet.
Syrup supply
The syrup containers are connected directly to the syrup connections on the unit.
The BiBs are connected to the syrup pumps and from there to the syrup connections on the unit.
