OPERATING THE MACHINE, AS ANY OTHER ELECTRICAL EQUIPMENT, ENTAILS OBSERVING
SOME VERY IMPORTANT SAFETY RULES, IN PARTICULAR:

English
Operatinginstructions 5
Z15.079 V01
— Do not touch it with wet or damp feet or hands.
— Do not operate when barefoot.
— Do not pull electrical feeding cable to unplug.
— Do not exposemachine to rain and prevent any water from entering, i.e. during washing.
— In case of failure and/or malfunction and any time there is apparent damage to the cable, cut power off and
call Assistance Service.
1.3 Damage prevention
ALWAYS comply with the followingnormsto avoid DAMAGESto the machine.
— Any use of themachine other than FROZENYOGURT andSOFT ICE-CREAM is to be considered improper.
— Do not use the cylinder when empty or with poorqualitymixtureand whenever the ice-cream runs off, quickly refill the
tub with the mixture. Indeed the ice-cream inside the cylinder oils its surface and conducts cold to the beater, that
reaches the same temperature. In case the cylinder gets empty, an ice skin will form, obstructing the beater for
mechanical overload.
— Inthe event youhave turnedon the refrigerator without inserting the beater in the cylinder first, wait for the cylinder to
warm up toroom temperaturebeforeproceedingtoinstallthebeater.
— The beater and the cylinder have been manufactured and assembled with precision: therefore they are sensitive to
changesof temperature, which could cause breakdownsor damagesto themachine's mechanical partsdue tothermal
dilation. NEVER allow suddenchanges of temperature to any refrigeratedparts: DO NOT pour water (hot or cold) in
the cylinder soon after ice-cream has been made.
— Do not drop or knock any of the machine's parts.
— Only useoriginal spare parts.
— If youare notgoing to usethemachinefor aprolongedperiod of time, orfor ever, proceed asexplainedin Chapter 9 -
Periodsof inactivity.
1.4 Importantsuggestions
— After each delivery, ice cream, make sure that the levers [16] tap [17] are placed
in the locked (up).
Otherwise the beater will soon freeze because the cylinder will get frozen and the
machine will be out of order (“oo” will appear on the display).
— Themachine includesseveral food-compatiblerubber gaskets. Replacethem ona
regular basis (ref. Chapter 8 - Maintenance) to avoidice-cream or mixture leaks.
— Each timethe machine isreassembled, check that gaskets, especially moving ones:
• thebeaters' gland
• thetap pistons' gasket
• thecarburettors' gaskets
AREINTACTANDWELLLUBRICATED. Usevaseline oranyFOOD COMPATIBLElubricant.
— Keepmachinealwaysclean, bothitsexternal surfacesandthose partscoming intocontact with the finalproduct.This
will make abetter ice-cream and will earn you the loyalty of newclients.

5 INSTALLING
INSTALLATION MUST BE CARRIED OUT EXCLUSIVELY BY CERTIFIED AND AUTHORIZED TECH-
NICIANS, AND ACCORDING TO THE NORMS CURRENTLY IN FORCE AND FOLLOWING THE IN-
STRUCTIONS BELOW.
5.1 Placing your machine
Place machine on a flat surface.
Place machine away from sourcesof heath, avoiding direct exposure to sunlight and
allowingair to circulate aroundit.
Place machine so that the side collection box [23] can be easily pulled out to be
emptiedon a regular basis.
Machines supplied with an AIR CONDENSING system need at least 50 cm room in front of the
condenser grill to allow therefrigerator to correctlyfunction. The machine's detailed dimensions
are included in the Technical handbook (Par. Technical Data).
5.2 Assembling
ASSEMBLE ALL PARTS BEFORE PLUGGING MACHINE IN.
Some components of the machine need assembling. Youwill find them in thepackage or insidethe back-up tub.
— Cones holders:
• Fix top[6]and bottom [9] bracketsonto left side panel withfixing knobs [7]. Thetopbracket [6] is theonewith the
biggest holes;
• place cones holder valves[8] in thebottom bracket holes[9];
• put cones holders [5] throughtop bracket holes andfit them in the valves[8].
— Drip tray:
• Fix driptray holder [12] onto the front panel with fixing knobs [14];
• place front drip tray cup [13] in drip tray holder.
— Tap handle:
• Remove handle cross pin [30] ;
• hook handle [16] fork to piston pin [31];
• insert cross pin [30]. You may need to slightly adjust handle.

Z15.069 V01
— Carburettors (in tubs)
• Checkgaskets[32] and, if necessary, lubricate them with food compatiblelubricant or vaseline;
• place carburettor [3] in the hole at the bottom of the spare mixturetubs [2].
5.3 Connecting to power
THE POWER INPUT REQUIRED BY THE MACHINE IS HIGH AND, THEREFORE, PARTICULARLY
DANGEROUS. THE MACHINE MUST BE CONNECTED TO AN ELECTRIC CIRCUIT WHICH COMPLIES
WITH THE NORMS CURRENTLY IN FORCE AND IMPLEMENTED BY CERTIFIED AND QUALIFIED
PERSONNEL. ALL SOCKETS MUST BE RELAYED BY ONE OR MORE DIFFERENTIAL CIRCUIT
BREAKERS AND EARTHED.
Themanufacturer shall not be responsible forany damages caused by a faulty electrical supply or earthing plant.
Note: If your machine requires THREE-PHASE power supply: it is STRONGLY recommended to install
THREE-PHASE MAGNETO-THERMAL SWITCHES designed to cut off power to ALL phases, even
when overload is on one phase only. Fuses, or other magneto-thermal switches, only cut off single
overloaded phases.
If currentis cut off from ONE of the THREE phases, the machinemay SEEM operating, however,
the motorswill shortlybe IRREPARABLY DAMAGED.
THE CIRCUIT MUST FEATURE THE FOLLOWING CHARACTER-
ISTICS:
— endwithanapprovedtypesocket(threepolesformonophasicinput1Nand5 poles
for three-phaseinput 3N – 3F).Thesocket'spoles must bemarked(RphaseorR-
S-T + neutral + earth);the earth polemustbe well recognizable;
A WRONG CONNECTION ON EARTH POLE CAN CAUSE SERI-
OUS DANGER.
— the socket must bedesignedtoprevent theplug from being insertedincorrectly;
— there must be a MAIN SWITCH to cut COMPLETELY off power from the socket,
this can be either included in the socket or within easy reach TO BE USED when
access to moving parts is required.
Check that the VOLTAGE and FREQUENCY written on the Technical Data plate
MATCHES thecircuit voltage and frequency.
A plug(three polesfor monophasic input 1N and5 poles for three-phaseinput3N–3F)
must be fittedonthe power supply cable'send.
The machine's power supply cable features coloured, labelled wires; these must be
connectedto the plug terminalsas from chart below.

ANINCORRECT CONNECTION INSIDE THE PLUG MAY POSE ASERIOUS RISK AND CAUSE
DAMAGE TO THE MACHINE (ELECTRONIC CARDS). HAVE ALL ELECTRICAL CONNECTIONS
CARRIED OUT ONLY BY CERTIFIED TECHNICAL PERSONNEL.
5.4 Connecting to water supply system
(water condensing machines)
If your machine is supplied with a water condensing system, supply and waste pipes must be set up.
Pipe unions are placed on the machine's rear panel, they are labelled [A] and marked:
IN: freshwater INLET
OUT: wastewaterOUTLET
Use linen-rubber pipessuitable to bear 15 bar pressure, placing a valve or faucet [B] BEFORE inlet pipe; use a 3/4rubber
holder [C] tightly fixed with a band [D] to connect pipesto the machine'sunions.
Follow these precautions:
— Do not reverse tubes and avoid tight bends and bottlenecks.
— The machine has been built to use WELL or AQUEDUCT water, at a MAXIMUM temperature of + 25…+28°C.
Don’t put hotter water (i.e. TOWER TANK water) in your machine if it hasn’t got the SPECIAL system to use
it (supplied only if asked): in thiscase, in the Technical Handbook, Par. Technical Data, it is indicated the right
water temperature to use your machine.
— Unsuitablepipes and joints may cause leaks and cause damage to your workroom and, in case of majorleaks
and splashes,to your machine. You can easily find household appliances' pipes (i.e. washing machines') on
the market, which have all therequirements, including rubber holders, as well as being economical.
— If the local water is hard and contains impurities, have a suitable water softener system or a filter fitted at the
top of the inlet pipe.
— Unless otherwise specified in the Technical Handbook, inlet water pressure must be 1.5 to 6 Bar (optimal
pressure: 3 Bar). If water pressure and quantity are inadequate, the machine will have CONDENSING PROB-
LEMS and will stop. If water pressure is higher, it is necessary to fit a pressure limiting device, appropriately
adjusted, above the delivery pipe, otherwise machine will be DAMAGED or anywayit will stop working.
IMPORTANT: When room temperature isbelow 0°C, remove any water from machine in order to
avoid freezing inside the condenser or pipes and causing SERIOUS DAMAGES. Please call the
authorizedAssistance Service.

which is going to increase;
— wait for the ice-cream to reach set THICKNESS. The beaters and the refrigerator
will stop. Nowthe ice-cream isreadyto be served.
Note: Before serving the ice-cream, it is recommended to check its
quality by pressingthe tap handle andcollectinga little of it. Please
put a container under the tap because of the potential splashes of
the ice-cream.
— Position an ice-cream cone or cup under the tap handle, then press it. After
servingthe ice-cream, BRING the taphandle toitsrest position.
After serving the ice-cream bring the tap handle EXACTLY to
its rest position. Otherwise the beater and the refrigerating
system will not stop automatically and the machine will block
for freezing.
Note: Also when the handle is up, the cylinders refrigerating system and the beater will work until the ice-
cream thickness the programmed substantiality again.
In order to get the most out of your machine:
— check regularly mixture level in the tubs;
In case that you need more than one consecutive release, constantly check the ice-cream
thickness on the Display. In order to avoid serving too soft an ice-cream, wait a few seconds
between releases, and/or alternate flavours. Mod. 320 can supply a maximumof one 75gr cone
every 18 seconds, mod. 336 a maximum of one cone every 10 seconds;

English
Softice-cream machine

Z15.069 V01
Promptly replenish tubs with mixture, if necessary. Failure to do this will cause the formation of
ice and subsequent blockage ofthe beater inside the cylinder.
— empty regularly side collectionbox [23]. If it becomesfull, water will overflowthrough its hole;
It isnot unusual to find tracesof mixture inthe sidecollection tray. However, if theyINCREASE in
quantity, replace beaters' packing gland gasket AS SOON AS POSSIBLE (Ref. Par. 7.2 - Parts
disassembling). Failure to do so, would cause mixture to leak inside machine and DAMAGE it.

— Re-assemble beater:
• reassemble the gaskets[41] and [42]
on the spring-guide [39];
• Reassemble the spring [40] and the
spring-guide [39], [39B] on thebeater
shaft [21], by pressing it completely
on the blades. The inside gasket [41]
is likely to do strenght to the spring
runner slipon the shaft.
The gaskets [41] and [42] areimportantcomponents and are subjected to continuous movement.
When worn they may TEAR. Check that all gaskets are INTACT before assembling them and
don't hesitate to replace them if necessary.
LUBRICATE each gaskets (even those in good conditions to be re-utilized) and their seatings
when re-assembling. UseFOOD COMPATIBLE lubricant, e.g. vaseline.
Assemble the spring and the beaters’ packing gland EXACTLY like in the previous picture. An
incorrectassemblage would SERIOUSLY DAMAGEthe machine.
• insert beaters[21] in the cylinders [20], turning them until shaft fits initsseating in the cylinder bottom (thebeaters
will protrude out of the cylinder edge by 1 cm pushed by the springs).
