Putting into and out of Operation
(To be done only by « operator »)
Putting into Operation
Before starting operation of the unit the transport lock must be removed.
In order to ensure the proper function of the unit, please follow the below outlined points in order.
Comply with the cleaning regulations defined by local laws before beginning each operation.
Connectors must be cleaned every time prior to attaching a beverage container.
Connect coupling to beverage container.
Open the valve of the CO
2
-cylinder and the pressure regulator. Check the CO
2
-pressure on the pressure
regulator.
It should be within the breweries specification of beer.
Set the CO
2
-pressure by turning the control screw:
To increase the pressure: Clockwise
To reduce the pressure: Counterclockwise
Afterwards check the CO
2
-lines for leaks by closing the CO
2
-valve. The pressure (high pressure gauge)
displayed at the pressure regulator should not drop. If it does, notify the service technician immediately! Do not
forget to re-open the CO
2
-valve if no leakage is evident.
Check the beverage lines for leaks. Only a visual inspection is possible. If liquid is leaking, call a service
technician.

Turning on the Unit
(To be done only by « expert »)
The water bath must be filled to the overflow with tap water. Refer to the technical data for the amount required.
Take care, that no water runs into the agitator motor. Reference: Use for this a suitable funnel and filler tube.
To prevent algae from forming in the water, add the disinfectant Molco (PN 14-9670-150). The 150 ml container
of disinfectant is sufficient for 30 liters of water.
Insert the mains plug for the cooler into the socket outlet with an earthed contact.
Set ice bank probe controller to designated function.
Units with water bath are ice bank controlled. These units start working automatically after the water bath is
filled with water. The compressor will cycle off after the ice bank has been built. (full ice bank capacity). The
control board of the unit has a time delay for switching on and off the cooling system when it runs in ice bank
mode. After the cooling system is switched on the running time is no less than 5 minutes. Switch off signals will
be ignored in this time. After the cooling system switches off, the delay is no less than 3 minutes. Switch on
signals will be ignored in this time. The 3 minutes delay occurs when turning on the unit and after a break in
power supply. This unit contains a 3-pin ice bank probe.
Brief Description controller:
Combined Ice bank-/Temperature Controller. The input information for compressor switching comes alter-
natively from a temperature probe or electrodes, which are located in the fluid detecting the difference between
water and ice.
For displaying the actual value, an optional remote display (TAA141647567) can be connected.
Operation Mode change-over
•
Potentiometer left fastened: The controller works with the electrodes only (ice-bank mode). With all
other positions, the temperature probe is used (temperature control).
•
Potentiometer left fa set coding link: Const. temperature control -3°C
