LABOTRONIC RTX
The lighting-up sequence of all LEDS on the bar of HARD-O-DYNAMIC monitor shows ice cream
status during its processing . The blinking of LED bar, as well as an ear signal mean that the cycle
is over and ice cream is ready for dispense.
NOTE
If ice cream is not dispensed soon after its preparation due to a temporary engagement of the
operator, ice cream is kept under beating and HARD-O-DYNAMIC steadily checks its consistency.
On a decrease in ice cream consistency, HARD-O-DYNAMIC starts up compressor again and
processing automatically restarts, thus bringing ice cream back to its best thickness conditions.
IMPORTANT
If a boiling mix at +85°C is used, it is necessary to press push-button "PRODUCTION"
before pouring it into the barrel.
3.4.1 Ice cream consistency
CARPIGIANI sets the best consistency value to 10.
HARD-O-DYNAMIC constantly secures a perfect ice cream in relation to the mix used, and yet
the operator can set personalized processing cycles through LABOTRONIC RTX.
Particularly creamy ice cream may require a higher consistency, whilst ice cream with low fat
contents, such as sherbets, requires a lower consistency degree
3.4.2 Changing ice cream consistency
To vary final ice cream consistency, press push-button while machine is
processing ice cream.
In order to get a harder ice cream, increase setting value displayed on monitor A by pushing arrow .
To get a smooth ice cream, decrease setting value displayed on monitor A, by pushing arrow
Example:
To vary consistency value from 10 to 8:
l Press push-button for ice cream processing
l Press repeatedly push-button arrow so decreasing value until number 8 is displayed;
the new set value of consistency is immediately stored.
l At the end of processing cycle, i.e. when buzzer will ring and LED bar will blink, ice cream
consistency value will be 8 instead of 10.
Typical value is 10, the new value set will be stored until it is not changed again.
The above described operation can be carried out on both EC and SPprograms. By EC cycle, the
machine control system is able to automatically recognize whether the operator has filled the
machine with minimum or maximum batched and whether it is working a fruit or cream product;
consistency value can be modified 8 to 12.
In SP program, the consistency value can be set 1 to 12.

3.4.5 Aftercooling
This function, which is a peculiarity of all LABOTRONIC RTX models, is particularly useful by
those models with a bigger output capacity (2 containers per cycle or more).
As a matter of facts, if ice cream in each container needs further preparation, such as garnish and
variegation or else before storage, ice cream still inside the machine being left at high speed of
dispense may loose its original thickness.
At any moment during DISTRIBUTION and upon operator's choice, it is also possible to press
push-button PRODUCTION in order to cool ice cream again. The result is a steady consistency
of ice cream, from beginning to the end of distribution. Starting Post-Cooling from SP (Speed)
production program, makes the compressor run 20 seconds only.

6. MAINTENANCE
CAUTION
Never put your hands into the machine, either during the operation or during cleaning.
Before servicing, make sure the machine has been set in "STOP" position and the main
switch has been cut out.
6.1 SERVICING TYPOLOGY
ATTENTION
Any servicing operation requiring the opening of machine panels must be carried out
with machine set to stop and disconnected from main switch!
Cleaning and lubricating moving parts is forbidden!
Repairs of electrical and freezing plants must be carried out by skilled engineers!
Operations necessary to proper machine running are such that most of servicing is completed
during production cycle.
Servicing operations, such as cleaning of parts in contact with the product, replacing of
stuffing box, disassembling of beater assembly are to be carried out at the end of a working
day, so as to speed up serving operations required.
Herebelow you can find a list of routine servicing operations:
- Cleanout and replacement of stuffing box
Cleaning should be carried out at the end of a working day, whilst replacement only after checking
of stuffing box and in the event product drips inside drip drawer.
- Cleanout of beater assembly
At the end of a working day
- Cleanout of sliding shoes
At the end of a working day
- Cleanout of panels
To be carried out daily with neutral soap , seeing to it that cleaning solution never reaches beater
assembly at its inside.
- Cleanout and sanitization
At the end of each working day, according to procedures described in section 5 of this manual.
WARNING
Never use abrasive sponges to clean machine and its parts, as it might scratch their surfaces.
6.2 WATERCOOLING
By machines with watercooled condenser, water must be drained from condenser at the end
of selling season in order to avoid troubles in the event that the machine is stored in rooms
where temperature may fall under 0°C. After closing water inlet pipe, withdraw drain pipe from
its seat and let water flow out from circuit.
6.3 AIRCOOLING
Clean condenser, periodically, so as to remove dust, paper and what can prevent air from circulating.
For cleanout, use a brush with long bristles or a bolt of compressed air.
ATTENTION
When using compressed air, put on personal protections in order to avoid accidents;
put on protective glasses!
Note: nevere use sharp metal objects to carry out this operation. Good working of a freezing plant
mostly depends on cleaning of condenser.
