on the display is low enough before opening the lid or extraction hatch;
English
Cream cooker
6
Z15.050
— Always proceed with extreme caution in the event of a power cut during work as the temperature of the
product in the cylinder could be high even though the display does not show it;
Note:
In the event of an electrical power failure during work the machine will, when power is restored,
automatically recommence the cycle that was in progress from the start. If, instead, the power supply
was interrupted when the cycle was already over, that is, when the final storage mode was already
engaged, then the machine will remain in storage mode.
— Never open the lid or extraction hatch if you are not sure that product temperature is low enough unless it is
absolutely necessary. If you must open the lid/hatch always wear suitable personal protection equipment
(gloves, overalls etc.) to prevent direct contact with the product.
— Do not insert fingers or objects in grills, slits or holes on the equipment.
— NEVER, FOR ANY REASON, remove, shift or hide the technical data info plate, the information/warning stickers
or any other warning signs applied on the machine.
— NEVER open the guard panels. The machine does not contain internal parts that can be maintained by the
user.
— The user MUST NOT carry out any tasks requiring tools that are not supplied with the machine or carry out
any tasks that are not described in this Instruction Manual. These tasks must only be carried out by the
Authorised Assistance Service.
— Before proceeding with any task that requires access to moving parts always disconnect the electrical power
supply.
— Should it be necessary to make modifications to the electrical system they must be carried out professionally
qualified, authorised personnel only.
— The machine has been designed for use by adults: do not allow it to be used by anyone not trained to do so
and ensure that children are not allowed in the vicinity of the machine.
— Modifying or attempting to modify this machine shall render any warranty null and void and is dangerous.
USE OF MACHINE, LIKE ANY OTHER ELECTRICAL DEVICE, REQUIRES OBSERVANCE OF SOME
ESSENTIAL REGULATIONS, ESPECIALLY THE FOLLOWING:
— Do not touch it with wet or damp hands/feet.
— Do not use it barefoot.
— Do not tug the power lead to remove the plug from the mains socket.
— Do not expose the machine to rain and ensure that no liquids enter the machine interior e.g. during cleaning.

Helpful tips
— When there is a lot of liquid product in the vat keep it moving by pressing the SLOW MIX
key prior to the
automatic cycle. If you do not do this sudden rotation of the mixer could cause splashing and product outpour.
— BEFORE starting production check that the programmed data is suitable for the type of work to be done, especially
the HEATING MAINTENANCE TIME indicated in HOURS and MINUTES.
— BEFORE and DURING production always keep HEAT TREATMENT REGULATION programming updated (1/3, 2/3
or 3/3 of vat) on the basis of the quantity effectively left in the vat; by doing this you will obtain the following advantages:
3
1)
you will minimise the time needed to complete the production cycle;
2)
you will avoid wastefully heating or cooling the unused part of the vat, thus saving on energy;
3)
you will prevent condensate falling into the product and lowering its quality.
SAFETY DEVICES
NEVER TAMPER WITH SAFETY DEVICES AND DO NOT USE THE MACHINE IF SAFETY DEVICES
ARE DAMAGED OR MALFUNCTIONING.
THE MANUFACTURER CANNOT BE HELD LIABLE FOR ANY DAMAGES OR INJURY CAUSED BY
TAMPERING WITH OR DISABLING SUCH DEVICES OR THEIR ASSOCIATED CIRCUITS.
THE MACHINE IF FITTED WITH TYPE-APPROVED PROTECTION GRILLS AS PER EN 294 06/1992
AND SUBSEQUENT AMENDMENTS; THESE HAVE BEEN DESIGNED ON THE ASSUMPTION THAT
THE MACHINE WILL BE USED BY PERSONS OF AT LEAST 14 YEARS OF AGE AND THAT ALL
SAFETY REGULATIONS ARE OBSERVED (SEE SECTION 1.2).
3.1
Extraction hatch grill
The protection grill [24] eliminates the RISK caused by inserting FINGERS in the
extraction hatch hole. A warning plate [25] in the immediate vicinity of the extraction
hatch nevertheless informs the operator of the danger.
IT IS ABSOLUTELY FORBIDDEN TO TAMPER WITH THE GRILL
[24] OR REMOVE IT FROM THE HATCH HOLE!
Do not insert any OBJECTS through the grill when the machine
is working for any reason whatsoever.
3.2
Magnetic cover sensor
This safety device, consisting of a magnet [A] and a type-approved magnetic contact
[B], causes a complete machine shutdown when the vat lid is opened. In this event
the Display reads "ooo" (three small squares). The machine will continue the cycle
only after the cover has been closed.
THE MAGNETIC CONTACTS AND RELATIVE MAGNETS ARE
ESSENTIAL SAFETY DEVICES!
The magnetic sensor on the lid IS NOT a routine shutdown
control: during routine use the machine must only be stopped
via the relevant keys on the control panel.
The magnet [1] and magnetic contact [2] MUST BE FITTED in proper observance of the assembly position indicated in
the figure and precisely as follows: the groove [3] and the printed semi-circle [5] on the lower surface of the magnet [1]
must coincide with the groove [4] (marked with a lateral white line) and the printed semi-circle [6] on the upper surface of
the magnetic contact [2]. The machine will only work if both parts are correctly fitted.

3.3
Cover slits
The cover [1] of the vat has an opening that incorporates slits [3] and a lid [2], which
allows ingredients to be added to the vat without opening the cover (and, therefore,
without stopping the machine). The incorporated slits [3], sized in compliance with
accident prevention guidelines, prevent FINGERS reaching the moving stirrer.
Do not, for any reason whatsoever, insert any OBJECTS
through the grill when the machine is not working.

INSTALLATION
INSTALLATION MUST ONLY BE CARRIED OUT BY QUALIFIED, AUTHORISED TECHNICAL PERSONNEL
IN COMPLIANCE WITH THE STANDARDS IN FORCE AND ACCORDING TO THE FOLLOWING
INSTRUCTIONS.
6.1
Positioning the machine
The machine must be positioned on the floor, on a flat, horizontal surface. Install the machine so that it is not near any
heat sources, is not directly exposed to sunlight and so that air circulates freely around each side of the machine.
Lock the front wheel brakes
Machines with AIR CONDENSATION require a gap of at least
50 cm in front of the condenser grill to ensure proper operation
of the refrigeration system. Details of overall dimensions are
given in the Technical Handbook (Technical Specifications
section).
English

Z15.050
6.2
Setting up the machine
Some parts of the machine are supplied unassembled inside the vat; these must be assembled.
FIT THE PARTS BEFORE CONNECTING THE MACHINE TO THE MAINS POWER SUPPLY.
— screw the lever [6] into the extraction
hatch hole [5];
— install the chute [7] under the
extraction hatch and tighten the fixing
knob [20].
6.3
Connecting to the mains power supply
THE MACHINE REQUIRES A HIGH-VOLTAGE POWER SUPPLY; THIS MAKES IT PARTICULARLY
DANGEROUS. THE MAINS POWER THAT WILL BE USED TO POWER THE MACHINE MUST BE
COMPLIANT WITH THE STANDARDS IN FORCE AND THE MAINS SYSTEM MUST HAVE BEEN
INSTALLED AS PER THE STANDARDS IN FORCE BY TRAINED, QUALIFIED PERSONNEL. MORE
SPECIFICALLY, BEAR IN MIND THAT ALL THE SOCKETS MUST BE CONTROLLED BY ONE OR
MORE RESIDUAL CURRENT-OPERATED PROTECTIVE DEVICES (SAFETY CUT-OUTS)
AND BE EQUIPPED WITH A PROPER EARTH CONNECTION.
The manufacturer cannot be held liable for any damages caused by an inadequate power supply system or earth
connection.
Note:
We STRONGLY recommend that you install 3-POLE OVERLOAD (MAGNETOTHERMIC) SWITCHES
designed to cut the power to ALL phases even in the event of only one of them being overloaded.
Fuses or other types of magnetothermic switch only cut power to the phase that has been overloaded.
If there is a power failure in ONE of the THREE phases the machine may APPEAR to be working
but the motors WOULD SOON BE IRREPARABLY DAMAGED.
THE SYSTEM MUST HAVE THE FOLLOWING CHARACTERISTICS:
— must end with a type-approved 5-pole socket and with suitable electrical and
mechanical characteristics. The socket poles must be marked with the relevant
symbols (phases R-S-T + neutral N + earth); the earth pole must be easily
recognisable;
ERRONEOUS CONNECTION ON THE EARTH TERMINAL CAN BE
A SOURCE OF GRAVE DANGER.
— the socket must prevent, via the use of suitable mechanical systems, erroneous
insertion of the wrong pin;
— there must be, incorporated in the socket or, in any case, in a place that can easily be accessed by the user, a
GENERAL SWITCH that COMPLETELY cuts the power supply to the socket.
Check that power supply VOLTAGE and FREQUENCY shown on the Technical Data
info plate CORRESPOND to actual mains values.
A 5-pole plug suitable for the power socket must be installed on the end of the power
lead.
The power lead of the machine consists of coloured wiring that may, if necessary, be
tagged; these wires must be connected to the respective plug terminals as indicated
in the following table.

6.4
Connecting to the mains water supply (machines with water
condensation)
If your machine features water condensation it will be necessary to connect the water delivery and outlet hoses.
The relative ports are located on the rear panel of the machine and are highlighted by a plat
IN:
[A] marked as follows:
fresh water INFEED into machine;
OUT: OUTFEED of water used by the machine.
For water connections use meshed rubber hoses suitable for pressures of 15 Bar, making sure you interpose a tap or
valve [B] BEFORE the delivery hose; to connect the hoses to the machine entry-outlet ports use 3/4" fittings [C], secured
with hose clips [D].
Bear in mind the following:
— Do not invert hose connection and make sure hoses are not squeezed, kinked or bent too sharply.
— The machine is normally made for use with WELL WATER or MAINS WATER with a MAXIMUM temperature of
+25…+28°C. Do not introduce COOLING TOWER WATER or in any case water at higher temperatures into
your machine unless it is equipped with SPECIAL systems for use of such high-temperature water (only
supplied on request): in this event, the water temperature suitable for operation of your machine will be
given in the "Technical Characteristics" section of the Technical Handbook.
— Unsuitable pipes/hoses or fittings can cause water leaks and disruption to work; if leaks are significant with
squirting of water there is a risk of damage to the machine. Special hoses for supplying water to electrical
appliances (e.g. washing machines) can be purchased; these are economic, have the required characteristics
and come supplied with a fitting.
— If the local water supply is very hard/impure have a limescale-removal or filtration system installed upstream
from the delivery hose.
— Unless specified otherwise in the Technical Handbook the incoming water pressure must be between 1.5
and 6 Bar (optimal pressure: 3 Bar). If water pressure and quantity are too low the machine will have
CONDENSATION PROBLEMS and will shut down. If water pressure in the system is too high it will be necessary
to interpose a suitably adjusted pressure limiter upstream from the delivery hose, otherwise the machine will
be DAMAGED or shut down.
With temperatures below 0°C it is ESSENTIAL to eliminate from the machine any water that
might freeze in the condenser or pipes/hoses; freezing water can cause SERIOUS DAMAGE to
the refrigeration system. Contact the Authorised Assistance Service.

— The Display comes on
and check (via the transparent cover) that the mixer shaft rotates CORRECTLY CLOCKWISE.
Press the SLOW MIXING key
again to stop rotation;
— switch off the machine by pressing the ON/OFF key
;
— if the direction of rotation is ANTICLOCKWISE (WRONG), connection must be modified as follows:
SET THE MAIN SWITCH OF THE SOCKET TO "0" AND REMOVE
THE PLUG;
•
open the plug and invert TWO of the THREE wires connected to the phases
(R-S, R-T or S-T);
•
re-close the plug, connect the electrical power supply to the machine and
repeat the test;
— if the direction of rotation is correct (CLOCKWISE) the machine is ready to be used: re-install the mixer [15]
in the vat.
The fixing knob [16] of the mixer musty be SECURELY TIGHTENED.

PRODUCTION
BEFORE STARTING PRODUCTION THE MACHINE MUST BE THOROUGHLY WASHED AND SANITISED
(REF. SECTION 8).
Avoid running the mixer dry (empty) as doing so could damage it.
Note:
if you expect to carry out two or more consecutive production cycles
of the same / similar products you need not carry out washing
between one cycle and the next.
Before starting the mixer ALWAYS check that the fixing knob
[16] is SECURELY TIGHTENED and that the relative seal [22]
is IN GOOD CONDITION and DEGREASED. If the knob is
accidentally unscrewed and falls in the vat during operation it
will cause SERIOUS DAMAGE to the machine.
To ensure good product quality observe the prescribed
quantities and program the machine correctly. Avoid exceeding
maximum quantities so as to prevent product overflow.

WASHING AND SANITISATION
10.1 Simple rinse - pre-wash
To eliminate product residue it is possible to carry out a brief rinse between two consecutive cycles.
— Close the extraction hatch. Pour warm water into the vat up to the half-full level;
— close the lid and press the SLOW MIXING key
leaving the mixer to run briefly;
It is pointless and damaging to run the mixer for long periods. The lack of lubrication (provided,
instead, by the ingredients during production) could wear the mixer or vat.
Do not switch on heating elements or the cooling system without good reason for doing so.
WARNING: DO NOT press the FAST MIXING key because it would cause violent, upward splashing
of water.
— stop the mixer, place a recipient under the extraction hatch and gradually open the latter to remove the water from the
vat.

10.2 Disassembly of parts
To aid washing and hygiene, all parts that come into contact with the product can be removed quickly and simply by the
user without the need for tools.
— Carry out a rinse (ref. Par. 10.1) to gain access to parts more easily.
IT IS DANGEROUS TO CARRY OUT THE FOLLOWING TASKS WITH THE MACHINE POWERED. SET
THE GENERAL SWITCH TO OFF BEFORE PROCEEDING!
— Extract the pins [13] from the hinge and remove the cover [1].
— Remove and disassemble the mixer:
•
unscrew the knob [16] and extract the mixer [15];
•
remove the safety spring [17] and remove the side scrapers [18];
•
remove the lower scraper [19].
10.3 Washing
All parts which come into contact with the product must always be washed and sanitised thoroughly in compliance with
the health standards in force.
IT IS DANGEROUS TO CARRY OUT THE FOLLOWING TASKS WITH THE MACHINE POWERED.
Note:
to ensure the machine has a long working life you are advised not to use water that is too hot, solvents,
abrasive detergents or rough sponges, especially on plastic parts.
— Clean the fixed parts of the machine thoroughly with water and detergent:
•
place a suitable recipient under the chute and open the extraction hatch;
•
clean the vat outlet using the supplied pipe cleaner;
•
clean the seal [21] of the extraction hatch thoroughly;
•
clean the upper surface and the inside of the vat;
•
unscrew the knob [20] and remove the chute [7];
•
clean the front panel and its parts;
•
clean the side panels and the rear panel.
DO NOT ALLOW WATER OR OTHER LIQUIDS TO PENETRATE THE INTERIOR OF THE MACHINE.
— Wash all parts disassembled by the user separately after removing them from the machine as described in
Section 10.2. Use warm water and a suitable detergent, then rinse with fresh water.

•
Wash the plastic scrapers with a brush to remove residues from the coupling fissures.
•
Wash the mixer, using the supplied pipe cleaner to reach inside the central sleeve.
•
Wash and degrease the seal [22] of the mixer fixing knob.
•
Wash the chute and cover. DO NOT disassemble the steel grill and lid from the cover.
— Dry all parts.
10.4 Reassembly of parts
— Assemble the mixer:
•
assemble the lower scraper [19] on the mixer [15];
•
assemble the side scrapers [18], positioning them as illustrated in the diagram, and insert the safety spri [17];
Insert the mixer gently inside the vat, keeping it in a vertical position and without dropping it.
During insertion check that the scrapers are positioned correctly.
•
the shaft coupling [27] must be inserted in the fissure [28] on the sleeve of
the mixer;
•
the fixing knob [16] of the mixer must be SECURELY TIGHTENED.
Before securing the fixing knob [16], always check that the
seal [22] is in good condition, is in its seat and is NOT GREASY,
as it must stop the knob from accidentally unscrewing. If the
knob falls into the vat during operation it will cause SERIOUS
DAMAGE to the machine.
— Position the cover [1] and insert the pins [13] from the hinge.
— Lubricate the seal [21] and sealing surface [23] on the extraction hatch thoroughly. Use FOOD-COMPATIBLE
grease (e.g. Vaseline).
Failure to lubricate will cause rapid wear of the seal and hatch, causing product LEAKS during
work.
— Re-assemble the chute [7] and tighten its fixing knob [20].
10.5 Sanitisation
The sanitisation procedure is similar to the rinsing task but must be carried out with a solution of warm water and disinfectant
for food machines.
See instructions for information on method of disinfectant use and dosage. After sanitisation rinse with water only (only
where specifically required).
After sanitisation close the cover and do not touch parts that come into contact with foods and
do not dry them with cloths or paper.
Check that all the water has flowed out of the vat. If necessary, briefly rotate the mixer to remove all residual water.

MAINTENANCE
11.1 Routine maintenance (user)
If the machine is used correctly and always washed with care, maintenance will be limited and simple.
The frequency with which the following tasks must be carried out depends on working conditions and intensity of use of
the machine.
— During routine operation:
•
check that the machine reaches and maintains programmed temperatures without any difficulty;
•
check that there are no unusual noises;
•
keep the external panels, the surrounding area and the floor underneath the machine clean. Dust, fragments of
paper or other small objects can get into the machine via the ventilation slits and compromise machine performance.
— During disassembly and wash procedures:
•
check that machine parts are in good condition;
•
change the mixer scrapers when they show signs of wear; these may appear as changes in the scraping profile
or residual (burnt) product on the surface of the vat;
•
periodically disassemble and check the seals [21] (of the extraction hatch) and [22] (of the mixer fixing knob). If
they are worn or damaged, replace them with original spare parts;
•
remember to DE-GREASE the mixer knob and relative seal;
•
remember to LUBRICATE the hatch sealing surfaces and seal. Use FOOD-COMPATIBLE grease such as Vaseline;
Do not apply leverage between seals and their seats with sharp objects.
periodically check that the seals [G] shown in the diagram are in good condition and
change them if they are broken, worn or swollen (in the latter case they tend to come
out of their seats).
Use only original seals made of food-quality rubber. The supplied spare parts kit
contains a complete set of seals with manufacturer-approved characteristics.
G
To change the seals correctly proceed as follows:
G
093
-
remove the old seals using a sharp object, preferably non-metallic, making sure seats are not scratched;
-
eliminate all traces of grease from the seat and the new seal before replacing.
•
always keep a stock of spare seals and scrapers: when ordering refer to the Spare Parts section of the Technical
Handbook;
•
run a visual check to ensure the power lead is in good condition.
Internal parts (to which the user MUST NOT gain access) must only be inspected by the Assistance Service.

Z15.050
11.2 Checking safety devices
Every three months check that all safety devices are working properly by carrying out the following test:
— if necessary switch off the machine by pressing the ON/OFF key
. Rotate the General Switch to position "0". If the
General Switch works properly the POWER warning light
must go out;
— open the cover and remove the mixer;
— check that the protection grill [24] is in good condition and secured properly;
— close the cover and rotate the General Switch to position “1”;
— press the ON/OFF key and then the SLOW MIXING key
(the mixer shaft must start). Then open the cover. If the
magnetic contact on the cover is working properly the mixer shaft will stop immediately and the display will read "ooo"
(three small squares).
If the machine works as described the safety devices are working properly.
THE MACHINE MUST NOT BE USED IF ONE OR MORE SAFETY DEVICES IS MALFUNCTIONING OR
DAMAGED!
11.3 Annual maintenance
Periodically (depending on the ambient conditions in the workplace) and, in any case, at least once a year, have the
Assistance Service carry out a general inspection of the internal parts of the machine.
ANNUAL MAINTENANCE MUST ONLY BE CARRIED OUT BY THE AUTHORISED ASSISTANCE
SERVICE, WHICH HAS THE REQUIRED TOOLS. MAINTENANCE TASKS THAT ARE THE EXCLUSIVE
DOMAIN OF THE ASSISTANCE SERVICE CAN BE DANGEROUS IF CARRIED OUT BY INEXPERT
PERSONNEL AND MUST, THEREFORE, NEVER BE CARRIED OUT BY THE USER.
12
PERIODS OF INACTIVITY
— If you do not expect to use the machine for a prolonged period proceed as follows:
•
wash the machine thoroughly (see Section 10);
•
cut the electrical power supply via the cut-off switch that fitted during installation and remove the plug from the
socket;
•
machines with WATER condensation: close the water tap and release the pressure in the delivery hose by
unscrewing a fitting. It is recommended that you remove both the delivery and outlet hoses and drain the water
from them. After a long period of inactivity check that they are not cracked or damaged and change any fitting
gaskets.
With temperatures below 0°C it is ESSENTIAL to eliminate from the machine any water that
might freeze in the condenser or pipes/hoses; freezing water can cause SERIOUS DAMAGE to
the refrigeration system. Contact the Authorised Assistance Service.
•
if the machine is to be stored in a different area, gather together all the documentation, including this manual,
and attach it to the machine (e.g. by placing it in the vat).
— If you wish to put the machine out of service permanently proceed as follows:
•
make the machine unusable by cutting the power lead (after removing the plug from the mains socket!);
•
do not disperse machine coolant gas or oil into the environment;
•
dispose of and/or recycle materials according to local standards in force.

TROUBLESHOOTING
IF YOU DETECT A MALFUNCTION DIFFERENT FROM THAT DESCRIBED, IT IS RECOMMENDED THAT
YOU CONTACT YOUR AUTHORISED ASSISTANCE SERVICE DIRECTLY.
The machine does not work or shuts down during operation …
… and the POWER WARNING LIGHT
DOES NOT COME ON.
Cause:
the plug is not inserted in the socket correctly or the socket switch is turned off.
Cause:
no voltage on a phase. Have fuses and/or system connections checked by a qualified technician.
WARNING: THE OTHER PHASES COULD BE LIVE.
Cause:
no mains power or no socket power. Check that circuit breakers, all-pole disconnector switches and
safety cut-out switches on the electrical system upstream from the socket are closed. If they are not
make sure no-one is carrying out repairs before closing them.
Cause:
an electrical system fuse has blown. Identify and eliminate the cause of the overload and change the
fuses with suitably-rated replacements.
Cause:
the socket is damaged. Have it changed by a qualified technician.
Cause:
the power lead is damaged. Remove the plug and contact the Assistance Service.
CUT THE ELECTRICAL POWER SUPPLY BEFORE TOUCHING DAMAGED WIRING!
Cause:
internal machine fault. Contact the Assistance Service.
The POWER WARNING LIGHT COMES ON
, yet the machine still does not work.
CUT THE ELECTRICAL POWER SUPPLY IMMEDIATELY via the General Switch.
Note:
The alarm is rarely triggered but this does occur under certain conditions. Therefore, before declaring
the machine faulty, switch it off for a time to allow temperature stabilisation (30…60 minutes), try using
it again and see if the alarm is tripped again.

Cause: the refrigeration system compressor electrical safety device has been activated
following a current overload. Switch off the machine, wait a few minutes and retry. If
the inconvenience is not eliminated or recurs frequently, contact the Assistance Service.
Cause: no power on a phase. Under such conditions the compressor generates an
electrical overload on the other phases and this trips the electrical safety device. Cut
the power supply to the machine and have fuses and/or system connections checked
by a qualified technician.
WARNING: THE OTHER PHASES COULD BE LIVE.
THE MACHINE MOTORS WILL BE DAMAGED IF THEY RUN WITH AN UNPOWERED PHASE.
Cause: the mixer electrical safety device has been activated through over-use or
mechanical overload. Check that the product in the vat is not too thick and that there
are no other causes of mechanical strain, switch off the machine, wait a few minutes
and try again. If the inconvenience is not eliminated or recurs frequently, contact the
Assistance Service.
Note:
in some cases it may be necessary to wait up to 30 minutes for the
overload devices to cool down.
Cause: the refrigeration system safety pressure switch has been activated following
excessive strain (REPEATED STARTS TO BE AVOIDED, high pressure, overheating).
Switch off the machine, wait a few minutes and restart. If the inconvenience is not
eliminated or recurs frequently, contact the Assistance Service.
Cause: Fault in refrigeration or control electronics systems. Contact the Assistance
Service.
(see also "Refrigeration insufficient or incorrectly deactivated”)
Cause:
Fault in glycol system. Contact the Assistance Service.
Cause:
Fault on heating elements. Contact the Assistance Service.
Cause: because of air bubbles in the glycol system the pump is unable to circulate it
correctly. Could be caused by a leak or because the machine has been laid on its side
or turned upside-down (NEVER DO EITHER). Contact the Assistance Service.
Cause: the glycol system pump is faulty. Contact the Assistance Service.
Causa: the glycol temperature sensor is faulty (disconnected or out of tolerance).
Contact the Assistance Service.
Cause: the control circuits are unable to cut the power supply to the glycol system
elements (which therefore stay on): the relative control switch is probably jammed.
Contact the Assistance Service.

Cause: the control circuits are not able to cut power to the compressor (so it therefore
stays on): the relative control switch is probably jammed. Contact the Assistance
Service.
Cause: the glycol temperature sensor is faulty (short-circuit) or the relative wiring is
damaged. Contact the Assistance Service.
Cause: the machine is running dry or with not enough product. Restore minimum
product quantity (at least 1/2 vat).
Note:
if you program a very high HEATING TEMPERATURE it is more
probable that the machine will trip this alarm (however, this only
happens under certain conditions).
Cause: the machine has been forgotten in MAINTENANCE
mode with HEATING
and product liquids have completely evaporated (the product is "burning"). Clean
and restart a new cycle with fresh product.
Cause: the product temperature sensor is faulty (disconnected or out of tolerance).
Contact the Assistance Service.
Cause: the product temperature sensor is faulty (short-circuited) or the relative wiring
is damaged. Contact the Assistance Service.
Cause: control circuits are unable to cut power to the compressor (which stays on):
the relative control switch is probably jammed. Contact the Assistance Service.
The machine repeatedly trips the electrical safety devices or the power supply fuses.
Cause:
electrical power system rating not high enough to power the machine.
Electrical characteristics of safety devices or fuses unsuitable.
Fault inside the machine. Contact the Assistance Service.
Refrigeration insufficient or deactivated incorrectly.
Machines with WATER CONDENSATION:
Cause:
the condensation water flow has been interrupted or is insufficient.
Water pipes are choked/kinked. Do not squeeze them or bend them too tightly.
Condensation water tap(s) are partially or completely closed.
