3.4 Functions within the dispensing system
NOTICE!
The description of how the unit works within the dispensing system is included in the relevant operator manual
for this unit; see the document "Overcounter cooler operator manual", document no. TD1019000.
3.5 Functions of the unit
NOTICE!
Flowchart; see chapter 10.1
The four basic functions of the unit are:
– Refrigeration
– Carbonisation
– Conveying
– Dispensing beverages
All functions are controlled 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
Ice is built up in the water bath to refrigerate the products. The agitator keeps the products refrigerated. The ice build-up probe
prevents excessive freezing of the ice build-up.
Each individual beverage type is dispensed by opening the valve assigned to the respective beverage component.
Valve control takes place via the unit's control electronics and depends on the inputs made via the control panel. The beverage
components flowing from the valves are supplied to the diffusor, where they are mixed. From there, they are poured into the cup
via the dispensing nozzle.
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
runtime is at least 5 minutes, even if a shutdown has been signalled beforehand. After switching off the refrigeration circuit, the
operation 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 and a probe for controlling the ice build-up in the refrigerating unit.
The 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 pressure-reducing valves and filters to the
carbonator pump on the unit. If still water is requested, the water flows via a heat exchanger in the refrigerated water bath to the
dispensing valve.
CO connection

The CO is supplied by the pressurised gas cylinder and pressure-reducing valve to the unit's CO

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.
Dispensing beverages
Each individual beverage type is dispensed by opening the valve assigned to the respective beverage component in each
respective dispensing valve.
The valves are controlled in accordance with the buttons on the control panels, which are pressed on the respective dispensing
valve, or the dispensing lever.
NOTICE!
Information on the dispensing valves installed on your unit can be found in the binding documentation for the
respective dispensing valve.
