13.5 Connection to the water network

(machines with water condensation)

If your machine features water condensation, it is necessary to prepare tubes for the feeding and draining of the water.

Do not let water from a TOWER in, unless they have been specifically designed to utilize water from a
tower. Unless otherwise specified, the machine is designed to utilize water from a WELL.

Note: the correct water temperature to operate the machine is specified in the Technical Handbook, Par. “Technical

data”.

14

English

Vertical batch freezer

The use of below standard tubes and connections may cause water drops, with consequent inconven­ience for Your laboratory and, if the drop is abundant with squirts, damage the machine.

Use linen-rubber tubes for water connection, arranged for 15 Bar pressures, interposing a valve or a faucet [B] ABOVE the
delivery pipe; use a 3/4" rubber holder [C], well fixed with a proper band [D] to connect the tubes at the machine’s union.

Note: Tubes for the water feeding of households are on the market (ex. dishwashers) which, in addition to being

cheap, feature the requested characteristics and are predisposed with a rubber holder.

The tubes must be long enough to allow the movement of the machine for cleaning (min. length 1.5 m).

Pipe unions are placed on the machine's rear panel, they are labelled

IN: fresh water INLET

OUT: waste water OUTLET

Follow the following precautions to avoid damages at the machine’s water circuit:

- do not invert the connection of tubes;

- if water in the area presents a high quantity of spur, install a suitable decalcification or filtration machine
above the delivery pipe;

- if not otherwise mentioned in the Technical Handbook, the incoming water’s pressure must be compre­hended between 1.5 and 6 Bar (ideal pressure: 3 Bar). If the pressure is higher, it is necessary to interpose a
pressure limiting machine, appropriately regulated, above the delivery pipe.

AVOID CONSTRICTION OR NARROW TURNS OF THE TUBES.

Note: The water outcoming the condensator, though being hot and not drinkable, is not polluted and can be reutilised.

Before storing machine (supplied with water condensation) at temperature lower than 0°C it is ABSO­LUTELY necessary to release all water from condenser and from feed and drain pipes, failure to do so will
cause water to freeze and SERIOUSLY DAMAGE refrigerating system. Call Technical Service.

data have been stored, the SET UP mode terminates and the machine is ready to be used.

14.4 Setting up for production

In machines with water condensation, check that the condensation water’s faucet is open;

- check that POWER indicator [Z1] is on. If not, check that machine is plugged in and Main Breaker is turned on
(on “1”);

- Check the lid is closed and the chute with protection flap is in position, otherwise the machine will not
operate. NO “ooo” (three small squares) should show on the Display;

- press the ON/OFF Pushbutton [K1].

Do not start beater before pouring mixture into the cylinder. The beater must not function dry, otherwise
it will be damaged.

- before beginning the production, wash, rinse and proceed at the sanitation with a
detergent and disinfecting solution (see Section 13-14 PRE WASHING and
WASHING).

Note: If you plan to have more than one consecutive production cycles, you can

avoid the washing between a cycle and the other, making sure you begin
with the clearer mixtures.

Before starting production ALWAYS check that beater’s fixing knob [7]
and the tilting blade’s fixing knob [24] (when supplied) are FIRMLY TIGHT­ENED and that all the relevant gaskets are intact and clear of any fat. If
the knobs should accidentally unscrew and fall in the cylinder during
the functioning, they would cause serious damages at the machine.

- check that extraction door is firmly closed and pour mixture in the cylinder. Only
use suitable perfectly preserved ingredients, in the correct amount. The maximum
and minimum amounts are indicated in the Technical Handbook, in the “Technical
Data” section.

Unsuitable mixture or insufficient amount of it can cause the develop­ment of ice, and cause damages or irregular functioning at the cylinder
and beater, while an excessive amount of mixture can forbid the cor­rect freezing, in addition to causing an excessive stress at the motor
and beater and overflows of product.

14.5 TEMPERATURE Cycle production

During TEMPERATURE CYCLE the machine stirs and refrigerates mixture at the set Final Temperature [Tf] until the
required thickness is reached. Stop cycle by pressing the cycle’s pushbutton.

- Close cylinder’s lid;

The Final Temperature [Tf] needs programming in accordance to the antifreezing ingredients (i.e. sugar,
alcohol) contained in the mixture. As a guideline, mixtures with LOW content of antifreezing ingredients
can reach –5…–6°C (23 ... 21°F), mixtures with MEDIUM content of antifreezing ingredients can reach –
7…–8°C (20...18 °F), mixtures with HIGH content of antifreezing ingredients can reach –9…–10°C (17...14
°F).

- check and adjust, if required, the previously set Final Temperature (ref. 14.3 - Setting Up). The manufacturer’s setting
(–7°C) (20 °F), is suitable for the majority of ice-cream mixtures;

- press the BUZZER Pushbutton [K6] to enable the buzzer at the end of the freezing cycle (the relative indicator [Z6]
lightens);

- press TEMPERATURE CYCLE Pushbutton [K5];

- wait for the end of the processing, that is when the programmed Final Temperature [Tf] is reached, when the REFRIG­ERATING SYSTEM indicator [K7] turns off and when you hear a sound signal.

- press TEMPERATURE CYCLE Pushbutton [K5] to end cycle and stop machine.

Note: At the end of the cycle, it is recommended to immediately remove product to avoid curdling due to prolonged

beating.

After reinstalling all the machine’s components (as previously described), carry out a sanitization with water solution and
disinfecting SANI-T-10 manufactured by SPARTAN CHEMICAL. Follow accurately the next steps:

STEP 1

Prepare a pail with a solution composed by room temperature water
and disinfecting SANI-T-10, respecting the following dosings:

use 3,5 gallons of water and 1, 3/4 oz. of disinfecting SANI-T-10;

STEP 2

Check that the extraction door is closed, open lid, pour the detergent
solution in the tank and close the lid again.

STEP 3

Press the beating pushbutton [K4], this will cause the sanitizing
solution to be agitated in the tank.

STEP 4

5 minutes later, press the beating pushbutton [K4] again, place a
pail beneath the extraction door and clear out the tank.

STEP 5

A potable water rinse is not necessary unless so specified by state
or local ordinance.

After the sanitization, close the lid and do not touch
with the hands anymore, nor dry with clothes or paper
all parts in direct contact with food.

Note: Additionally to the operations mentioned in this Chapter,

it is recommended to clean machine’s outer panels and
all of its outside parts.

17 MAINTENANCE

The machine requires a very limited maintenance. Periodically, we suggest to:

- check the good state of the parts of the machine. The disassembly, for example during the accurate washing, is an
ideal opportunity for a similar check (ref. Par. 17.1);

- check that electric power cable, pipe fittings (rubber holder) and water pipes (where present) are not damaged;

It is then useful to maintain the external panels clean and the surrounding area. Dust, paper fragments or other small objects
may penetrate in the machine through the ventilation loopholes (in particular if equipped with air condensation and rapidly
compromise its correct functioning.

The inside parts, to which the user MUST NOT accede, must be checked by the Technical Service.

17.1 Maintenance during the components disassembling

Check the integrity of gaskets (indicated with [G] in the figure) and substitute those that
are deteriorated.

G

G

- remove the old gaskets by using a sharp non-tool, possibly non-metallic, paying attention not to scratch the seating of
the gaskets themselves;

- clean the seatings and the gaskets from any kind of grease before inserting the new gaskets.

Use exclusively original, compatible with food, rubber gaskets. The spare bag
contains a complete series of gaskets approved by the manufacturer.

093

Check that the plastic runners' scraping edges are not scratched or dented, and that
the side runners are not worn as shown in the picture. If they appear worn, replace
them.

To correctly replace the gaskets it is necessary to:

A thorough scraping of the cylinder will provide BEST PERFORMANCE
by the batch freezer and HIGH QUALITY ICE-CREAM. Therefore we
recommend to frequently replace plastic scrapers (at least once every
THREE MONTHS).

A yearly preventive replacement of all wearing parts and all gaskets is recommended. We suggest you to always keep a
spare supply: to order it, refer to the Spares Section contained in the Technical Handbook.

17.2 Yearly maintenance

Periodically (basing yourself on the environmental conditions in which the machine operates) and in any case once every
year, make sure to have a general checkup.

THE CHECK-UP MUST BE MADE BY THE AUTHORISED TECHNICAL SERVICE, OR, IN ANY CASE, BY
TECHNICALLY AUTHORISED PERSONNEL WITH ADEQUATE TOOLS. THE MAINTENANCE OPERATIONS
RESERVED TO THE SERVICE TECHNICAL CAN BE DANGEROUS IF CARRIED OUT BY NON-PROFES­SIONALS, THEREFORE, FOR HIS OWN SAFETY, THE USER MUST NEVER CARRY THEM OUT.

18 PERIODS OF INACTIVITY

If long periods of inactivity are foreseen, proceed as follows:

- wash up completely the machine (see Section 16-17);

- switch off the power breaker and unplug the machine;

- machines with WATER condensation: close the water faucet and relieve pressure from inside the delivery pipe by
unscrewing one of the pipe fittings. Remove both delivery and drain pipes and let all water out. Before using the pipes
again, following a long period of inactivity, check for any damages or cracks and replace, if necessary, pipe fittings’
gaskets.

- if the machine will be stored in a different place, group all the documentation, together with the present manual, and
enclose it at the machine (i.e. in the cylinder).

Before storing machine (supplied with water condensation) at temperature lower than 0°C it is ABSO­LUTELY necessary to release all water from condenser and from feed and drain pipes, failure to do so will
cause water to freeze and SERIOUSLY DAMAGE refrigerating system. Call Technical Service.

19 MALFUNCTIONS

WE RECOMMEND YOU TO CALL IMMEDIATELY THE TECHNICAL SERVICE IF A MALFUNCTION DIFFER­ENT FROM THOSE HERE DESCRIBED IS FOUND.

Note: the following malfunctions do not refer to problems noticed in the installation phase, but ONLY on correctly

installed - and already functioning - machines.

THE MACHINE DOES NOT WORK OR STOPS WORKING.

With the Main Breaker on 1 the POWER indicator [Z1] DOES NOT TURN ON.

Cause: The plug is not correctly plugged.

The plug is defective. A qualified technician should substitute it.

Power in the socket is missing. Check that the breakers, the omnipolar switches and the
differentials (lifesavers) on the electric plant are closed. If they aren’t, before closing them,
make sure that no one is making electrical maintenance.

A protective fuse of the electric plant is blown. Find and eliminate the eventual cause of
overload. Substitute blown fuses with others of the same kind.

The supply cable is defective. BEFORE, cut down electrical feeding at the socket by opening
the breaker above it, then disconnect the plug and call the Technical Service.

DO NOT TOUCH THE DAMAGED ELECTRICAL CABLES BEFORE HAVING CUT DOWN
THE ELECTRICAL SUPPLY!

With the Main Breaker on 1 the POWER indicator [Z1] TURNS ON, but the display shows 3 small squares
and the machine does not work.

Cause: The lid is not correctly closed or tends to open;

The product lifts the lid due to an excessive quantity or an excessive volume increase. Use a
smaller amount of mixture or more suitable ingredients.

The lid’s magnet is damaged. Call the Technical Service.

THE MAGNETS AND THEIR CONTACTS ARE IMPORTANT SAFETY MACHINES!

Cause: The refrigerator’s safety pressure switch comes on. Check the machine’s air/condensing

water supply. See also par. Malfunctions: “The refrigeration is insufficient…”

The compressor’s back up relay switches off, following excessive stress (repeated starts,
high pressure, overheating). Stop the machine, wait a few minutes and try again. If the fault
should not be eliminated, or should frequently repeat, call the technical service.

Note: it may be necessary to wait up to 30 minutes for the thermal protections to cool down.

Cause: The Beater’s back up relay switches off, following overuse or mechanical overload. Check

that the eventual product in the cylinder is not excessively dense and that there are no other
causes of mechanical stress.

Overloading of the beater motor during TEMPERATURE CYCLE can be caused by the prod­uct excessive thickness. This is because the Final Temperature is too low for the type of
mixture in use. Set Final Temperature to a higher setting (less cold).

Stop the machine, wait a few minutes and try again. If the fault should not be eliminated, or
should frequently repeat, call the technical service.

Note: it may be necessary to wait up to 30 minutes for the thermal protections to cool down.

28

English

Vertical batch freezer

With the Main Breaker on 1 the POWER indicator [Z1] TURNS ON, but the machine does not work.

Cause: Break down of inside parts or at the electronic controls. Call the Technical Service.

THE TEMPERATURE CYCLE DOESN'T AUTOMATICALLY END BECAUSE PRODUCT DOES
NOT REACH PRESET FINAL TEMPERATURE.

Cause: Final Temperature [Tf] is too low. Final Temperature [Tf] needs programming in accordance to

the antifreezing ingredients (i.e. sugar, alcohol) contained in the mixture. As a guideline,
mixtures with LOW content of antifreezing ingredients can reach –5…–6°C, mixtures with
MEDIUM content of antifreezing ingredients can reach –7…–8°C, mixtures with HIGH con­tent of antifreezing ingredients can reach –9…–10°C.

THE MACHINE CAUSES REPEATED RELEASES OF THE MAINS ELECTRICAL PROTEC­TIONS OR THE INTERRUPTION OF MAINS FUSES.

Cause: The capacity of the electrical plant is not sufficient to feed the machine.

The electrical characteristics of protections and fuses are not adequate.

Inside breakdown of the machine. Call the technical service.

THE REFRIGERATION IS INSUFFICIENT OR DISACTIVATES IN AN ANOMALOUS WAY.

AIR CONDENSATION machines

Cause: Obstacles are placed at the air conditioning’s opening, at a distance lower than that de-

scribed. Restore the minimal distance reported in the Technical Handbook.

The room temperature is too high and condensation is inadequate.

The air condensator is dirty. Request the cleaning at the Technical Service.

The condensator’s fan is broken. Call the Technical Service.

Break down of the refrigerating circuit or at the electrical controls. Call the Technical Service.

WATER CONDENSATION machines:

Cause: The flow of condensation water is interrupted or insufficient.

The water tubes present constrictions. Avoid constrictions.

The water condensation faucet/s are partially or totally closed.

The static pressure valve must be newly regulated, otherwise it is broken. Call the Technical
Service.

Note: To check if the water correctly flows and if the static pressure valve is regulated, it is sufficient

to temporarily detach the water outlet tube (at the end not connected at the machine). Water
must flow only when the refrigerating plant is in function.

The incoming water’s temperature is higher than that prescribed in the Technical Handbook.

Cause: The compressor is overheated due to a lack of ventilation. Clean the scots and restore the

minimal distances for the circulation of air at the sides of the machine.

Note: it may be necessary to wait up to 30 minutes for the thermal protections to cool down.

Break down at the refrigerating circuit, or at the electrical controls. Call the Technical Service.

English
Operating instructions

UNUSUAL NOISINESS.

The noisiness comes, mainly, from the cylinder, when the beating is activated.

29

Cause: A layer of ice has developed between the beater and the cylinder: the mixture is not idoneous,

or is not sufficient.

The Beater’s scrapers might be damaged or too worn. Check that the scrapers edges are not
scratched or dented, and that the side scrapers are not worn as shown in the picture. If they
appear worn, replace them.

The beater and/or the cylinder are damaged or excessively worn. Call the Technical Service.

Cause: The tilting blade’s fixing knob (where featured) is loosened. Check the state of the gasket(s)

(eventually substitute them) and tighten again the fixing knob(s).

The beater and/or the cylinder have gone through a sudden temperature change, and stress
mechanically. Stop the machine and wait a few minutes.

The noisiness DOES NOT come from the cylinder, or is also present when the beating is not activated.

Cause: Inside break down. Call the Technical Service.
