9 ICE CREAM PRODUCTION PROGRAMS By pressing the SET key and then the ICE CREAM PRODUCTION key or PRODUCE MINIMAL AMOUNT OF ICE CREAM key, the currently selected program of the ice cream making control method is displayed. By pressing the UP and DOWN keys, you can select a program (Pr1 ≈ Pr4). The selected program is valid if it is confirmed by the SET key. Symbolical presentation on how to choose a program:
9.1 PR1 – PROGRAM, WHICH ICE CREAM PRODUCTION IS BASED ON THE TEMPERATURE AND POWER SETTING
This program is designed in a way, which meets the requirements of almost all users. It is based on the balance between temperature and power of ice cream production. The user is enabled to produce a soft but compact ice cream, which is suitable to be filled in cornets. The range of this program includes a scale of numbers (values) from 1 to 15. Low numbers represent the production of soft ice cream while higher numbers represent the production of harder, compacter ice cream. The program Pr1 is a very flexible and simple program, which makes it very popular among ice cream sellers. Pressing the ICE CREAM PRODUCTION key or PRODUCE MINIMAL AMOUNT OF ICE CREAM key will activate the ice cream production function. Pressing the SET key will show the final temperature of ice cream for 5 seconds (values from 1 to 15):

During these 5 seconds, the user may increase the number (value) (by pressing UP) or lower it (by pressing DOWN). By pressing SET within 5 seconds since the last change of the value, the new value becomes the assigned one.
Symbolical presentation on how to set the final ice cream temperature:
9.2 PR2 - PROGRAM, WHICH ICE CREAM PRODUCTION IS BASED ON THE TIME AND POWER SETTING
This program is manly based on the balance between time and power of the ice cream production. However, the emphasis on the production time is greater, since specific values are based only on the time, but also on the power of ice cream production at higher values. The user is enabled to produce soft but compact ice cream very quickly. This program is suitable for all users, who always produce the same amount of ice cream, because one is able to always produce the same quality of ice cream in the same amount of time. Regarding the set time and the quantity of the ice cream mixture different results can be achieved. In this way shorter time means softer ice cream and longer time means harder, compacter ice cream.
In case time and power controlled ice cream processing is selected (Pr2), the completion of processing is determined by setting the processing time; this may be set by the user according to the desired characteristics of ice cream. Pressing the ICE CREAM PRODUCTION key or PRODUCE MINIMAL AMOUNT OF ICE CREAM key will activate the ice cream production function. Pressing the SET key will show the set time for ice cream processing for 5 seconds: During these 5 seconds, the user may increase the set time (by pressing UP) or lower it (by pressing DOWN). By pressing SET within 5 seconds since the last change of the value, the new value becomes the assigned one (settings of the time range 2 ≈ 15 min).

9.3 PR3 - PROGRAM, WHICH ICE CREAM PRODUCTION IS BASED ON THE FINAL DENSITY OF THE ICE CREAM
This program is especially suitable for those users, who want to achieve a desired density for each individual ice cream. It is based on power, which is essential for achieving the maximal density of the ice cream. It is manly used by more experienced ice cream sellers and producers. In case consistency controlled ice cream processing is selected (Pr3), the completion of processing is determined by setting the final consistency of ice cream; the user according to the desired characteristics of ice cream may set this. Pressing the ICE CREAM PRODUCTION key or PRODUCE MINIMAL AMOUNT OF ICE CREAM key will activate the ice cream production function. Pressing the SET key will show the set time for ice cream processing for 5 seconds: During these 5 seconds, the user may increase the set consistency (by pressing UP) or lessen it (by pressing DOWN). By pressing SET within 5 seconds since the last change of consistency, the new consistency becomes the assigned consistency. A selection between 20 and 100 is allowed. This is used if we want a soft ice cream (lower numbers), or if the user wants a precisely defined ice cream density. Symbolical presentation on how to set the final ice cream density:
9.4 PR4 – PROGRAM, WHICH ICE CREAM PRODUCTION IS BASED ON THE OPTIMUM DENSITY OF THE ICE CREAM
As well as pr3 this program is also based on power, the only difference lies in the fact that the machine itself defines the optimum density of the ice cream and not the user. It is fully automatic and works faster than Pr3. The user can not change the settings of the program. This program is suitable for inexperienced users and/or beginners.

10 CHANGING PARAMETERS OF MACHINE
10.1 ADDITIONAL AUXILIARY FUNCTION KEYS
By pressing firstly the SET key and then the ICE CREAM PRODUCTION key or PRODUCE MINIMAL AMOUNT OF ICE CREAM key and afterwards the FAST MIXING – EJECTION OF ICE CREAM key, one enables changing of parameters (A.00 ≈ A.03). By pressing the keys UP/DOWN one can choose the parameter, by pressing the SET key one can enter new values of the parameter. The changes become only valid if one presses the SET key to confirm the changes. If the entering of new parameter values ends with pressing the FAST MIXING – EJECTION OF ICE CREAM key, the new values will not be valid (the previously entered value stays valid). The meaning of the parameters depends on the chosen program (Pr1 ~ Pr4).
Symbolical presentation on how to set parameters A.00 ~ A.03:
Ice cream production parameters for programs (Pr1 ~ Pr4): The user can during the phase of ice cream mixture production define an automatic fast mixing with cooling (auxiliary intensive mixing) by means of parameters A.00, A.01, A.02.
[ A.00 ] Entry time into the fast mixing procedure
0s .. 300s (default value 50s)
This is the time, after which the fast mixing procedure starts. The time includes a time period between 0~300 seconds under the condition that the minimal needed time for producing the ice cream mixture was reached (after the prohibition time exceeds). If the value 0 is entered the fast mixing will not start due to the parameter A.00.
[ A.01 ] Entry temperature into the fast mixing procedure
-30º .. 10º (default value -13°C)
This is the temperature needed (-30 °C, 10 °C – temperature of the cooling gas) at which the fast mixing procedure starts. If one enters the temperature of 10 °C, the fast mixing procedure is not possible due to the temperature.
32
[ A.02 ] Time of fast ice cream mixture mixing
0s .. 200s (default value 0s)
This is the time of fast mixing of the ice cream mixture. Fast mixing is possible only if one of the already described parameters is fulfilled (A.00, A.01). The time of fast mixing includes a time period between 0 and 200 seconds. If the value 0 is entered into the parameter A.02 the fast mixing is disabled.
The user can define the required ice cream production time by means of the parameter A.03.
[ A.03 ] Entering the required ice cream production time in minutes
0.0min~10.0min (default value 0min)
The test of required time becomes active when the required time is bigger than the minimal needed time for producing ice cream. In such a case the ice cream mixture is finished before the required time, therefore it gets mixed again by the machine (8 seconds without cooling – deactivation of the compressor) and the whole ice cream production process starts from the beginning. This cycle is executed only once, after that the machine finishes the ice cream production process, even if the required time has not been reached yet.
10.2 SETTING THE NUMBER OF REVOLUTIONS (MODELS WITH INVERTER ONLY)
Models with a built-in inverter allow the operator to set the number of revolutions for mixing. The operator is thus able to adjust the machine to suit the preferred method of making ice cream. Recommended minimum and maximum number of revolutions for mixing: If MIXING is activated and the appliance is not in the SET phase, the operator may set the number of revolutions by using the UP and DOWN keys. Pressing the UP key will show the preset number of revolutions in Hz for 4 seconds: During these 4 seconds, the operator may increase the number of revolutions (by pressing UP) or decrease it (by pressing DOWN). By pressing SET within 4 seconds since the last change of the number of revolutions, the new number becomes the assigned value. Models with a built-in inverter that are meant for special markets have a set number of revolutions (33~36Hz), which can not be changed until the ice cream mixture reaches a certain density / temperature. As soon as the ice cream mixture reaches the required density / temperature, the machine’s revolutions can be set by the user (now the user can define the number of revolutions).

11 PROTECTION OF THE USER AND OF THE MACHINE
11.1 PROTECTION OF THE USER
A safety switch, which is built into the machine under the rim of the mixture treating cylinder, protects the operator against injuries that might be caused by the mixer’s rotation. Opening the mixture treating cylinder coverlid will cause the operation of the mixer engine to shut down. In this case, the appliance must be set to STOP position and the mixture treating cylinder coverlid must be closed.
11.2 ELECTRICAL OVERLOAD PROTECTION
Electrical installations are protected with appropriate FUSES. If the FUSES terminate the operation of the appliance upon its start-up, the error causing this action must be found and corrected.
11.3 THERMIC SAFETY DEVICES
The mixer engine and the compressor engine are protected with thermal sensors. If temperature reaches the maximum allowed value, the protection shuts down the engine operation. In this case, press the key STOP and allow 15 - 20 minutes for the engine to cool down. After this time, the appliance is again ready for normal programming and operating (see the section OPERATING THE APPLIANCE).
11.4 PROTECTION OF THE COOLING SYSTEM
The cooling system is protected with the pressostat at the maximum pressure of 2,5 MPa (25 bar) for the cooling gas R507. In the case of water shortage, the protection shuts down the operation of the cooling compressor.
