193 BAR P

3. DIRECTION FOR USE

3.1 MACHINE CONFIGURATION

The machine has a motor to drive the beater, and a cooling system with water or air condenser.
Soft ice cream is prepared by filling the tanks with cold mix (+4°C) and starting the automatic
production cycle, until the ideal ice cream consistency set by CARPIGIANI is reached. Thanks
to the pump, the mix enters the freezing cylinder already mixed with air; ice cream is produced
only when it needs to be served. The spigot head allows a single portion of soft ice cream to be
distributed. At the same time, the same amount of mix moves from the tanks into the freezing
cylinders.

3.2 ELECTRONIC CONTROL KEYBOARD AND BUTTON
FUNCTIONS

Details of the panel are shown in the picture below.

commands for any of the main functions. Pressing STOP from any function, the
machine will stop.

Function selection button

A repeated pressure of this key allows the selection of Distribution, Storage and
Cleaning. The function you select will be shown through its led lighting on the key
pad. The function you select last will be activated after 5 seconds. Once the function
has been selected, Selection key will have another function, i.e., scrolling the pages
with data relevant to the machine (such as tanks and cylinders temperatures,
dispensed cone number, etc.). To select another function, you will have first to pass
to Stop.

PRODUCTION function

When selecting this function the led lights up and the mix into the cylinder is freezed
until its set consistency (pre-set HOT setting) is reached.

STORAGE function

When selecting this function, led lights up and the machine stores the mix both in
hopper and cylinder at a pre-set temperature of +4°C.

Note: It is advisable to leave the machine in this function in case of extended idle
times.

CLEANING function

When selecting this function, led lights up, the beater and the mix pump run, while
the refrigeration unit is off. This function is timed and ends automatically when the
set time (usually 10 minutes) is reached. The display indicates decreasing time.

Note: Too an extended operation time is not advisable.

PASTEURIZING function

Disabled function

“WAIT” and “SERVE”

If ice cream consistency drops below the programmed value, the red led WAIT on the
key pad will light. This means that ice cream is not ready to be dispensed. When its
consistency raises and ice cream distribution can restart, the led WAIT will switch off
and the led SERVE (of course the one relevant to the ice cream flavour selected) will
switch on.
When you dispense an ice cream portion from the central (mixed ice cream) piston and
ice cream in one of the cylinders has not reached the programmed consistency, that side
will be locked and the led WAIT will light: relevant outlets will be deactivated. If you
keep on taking ice cream out from the central spigot, only will ice cream flavour be
dispensed which led "SERVE" is on.

Tank mix level

Low mix level in the tank is only indicated by the display.
Low level on the left side is indicated on display by a blinking message
“ç add mix”:
Low level on the right side is indicated on display by a blinking message
“Add mix è”:

3.4 "R" PUMP

"R" pump allows, by changing position of regulator pos. 271, to vary proportions between air and
mix conveyed to the freezing cylinder; so, within certain limits, it allows overrun regulation
depending on mix used.
"R" pump regulator should be set to the middle position.
If, after dispensing a significant number of cones, ice cream is too heavy and wet, you may move
R pump regulator a notch at a time towards the right. If ice cream comes out of spigot mixed with
air bubbles, then turn R pump regulator a notch at a time towards the left.

3.5.3 Hygiene

Mildew and bacteria grow rapidly in the ice cream fat contents. To eliminate them, it is necessary
to thoroughly wash and clean all parts in contact with mix and ice cream, as described above.
Stainless steel and plastic materials, as well as rubber used in the construction and also their
particular shapes make cleanout easy, but cannot prevent proliferation of mildew and bacteria
if not properly cleaned.

3.6 STARTING THE MACHINE

After installing the machine according to the instructions given in the chapter INSTALLATION,
and after carefully cleaning and sanitizing the machine, proceed as follows:

Remove the compression pipes from tanks bottoms and place them in the sanitizing solution.

Filing the tanks :

• Take 1 bag of mix from the refrigerator.

NB.: Mix to be poured at a temperature of 4-5°C.

• Pour one bag of mix intoeach tank allowing it to be

convenyed into the freezing cylinders. Mix level in the tank
must never reach the pump (see picture) and more mix must
be added when level goes below about 2 cm from tank
bottom.

• Lower the distribution handles and wait until only full

strength mix will come out of the lid; close the handles.

Connecting the mix pressure pipe :

• Keep on pouring the mix and wait till the cylinders have been completely filled (during

that time you see bubbles in the tanks); with sanitized hands, draw the compression
pipes out from the sanitizing solution and insert them into relevant tank bottoms.

• Turn the compression pipes clockwise and align them to the pump, insert the connection

pipes (pos. 207) well into the compression pipes, then into the pumps and lock them.
Mix inside the tanks shall never reach the pump (see the picture); furthermore mix shall
be added whenever level is 2 cm from tank bottom.

• Place tank covers back.

• Select the function Production and after a few minutes, ice cream is ready for

distribution.

3.7 PRODUCTION

Dispense icecream without exceeding the machine production rate as shown in the table on page

10. If you do not exceed it, and provide to refill the machine with fresh mix, you can be sure you
will never have to stop selling, even during peak hours.

When the message AGGIUNGERE MIX (ADD MIX)è it means that the mix has reached the
minimum level in the right-hand tank and, as a consequence, more mix must be added because
the machine would dispense a programmed number of cones, and then it would automatically set
to Storage. If the mix has reached the minimum level in the left-hand tank, the display indicates

çAGGIUNGERE MIX (ADD MIX); if mix has reached the minimum level in both tanks, the

display will indicate
During closing time of the store, set your machine to STORAGE by pressing STOP and through
SELECTION key, select the function STORAGE.

You will save significantly on energy consumption, as the compressor runs only for the time
strictly necessary in order to keep product at its correct temperature.
When you reopen the store, set the machine to STOP and then to PRODUCTION. Within a few
minutes youghourt icecream will be back at the correct consistency for sale.
If the machine has been stopped a long time due to a power failure, it is necessary that you check
product temperature before starting the sale again; if the temperature is over +6°C, the machine
must be emptied, cleaned and sanitized, and filled up with new fresh mix at +4°C.

4. SAFETY DEVICES

4.1 SAFETY SYSTEMS ON THE MACHINE

PRESSURE SWITCH

It protects the refrigeration system and causes the compressor to stop if the pressure of the system
exceeds the pressure switch setting value. This may occur especially due to a lack of water
(machine with water condenser) or air circulation problems (machine with air condenser). The
switch resets itself automatically.

WARNING

if the compressor runs for an excessive time or stops and starts repeatedly,

this indicates insufficient condensation; check the causes.

OPERATOR PROTECTIONS

Safety microswitch on the lid.
A microswitch is located on the lid of the beating cylinder, containing the beating unit, which stops
the machine immediately when the lid is opened. The machine enters STOP mode and the display

shows the message "Front lid open" and the led

When the lid is closed back, the machine remains stopped and shuts off the alarm on the monitor.

6. MAINTENANCE

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 the machine production cycle.
Servicing operations, such as cleaning of parts in contact with the product, replacing of stuffing
boxes, disassembling of beater assembly are to be carried out at the end of a working day, so as
to speed up servicing operations required.
Herebelow you can find a list of routine servicing operations:

- Cleanout and replacement of stuffing box

Should you ever find that some product drips from dripping tubes on machine front, it means
that stuffing boxes (pos. 28) have lost their tightness; when disassembling the beater, it is
consequently necessary to check them and, according to the machine working period, to replace
and alternate them with the stuffing boxes included in the machine accessory kit.
If the stuffing boxes show no defects, they can be used again after washing them, when at room
temperature they have regained their original shape.
Replace stuffing boxes as follows:
Draw the beater assembly out.
Remove stuffing box from its seat
Lubricate the new stuffing box and mount it
Before putting the stuffing box away, clean and lubricate it so as to reach its elasticity again.

WARNING

If you continue to work after noting traces of product in the drawer, you further accen-

tuate the leakage of the stuffing box; this can lead to a malfunction of the machine serious

enough to halt production.

- Cleanout of beater assembly, cleanout of pump or feeding needle, cleanout and sanitization

of the all machine

To be carried out every day, according to procedures described in section 5 of this manual.

- Cleanout of panels

To be carried out daily with neutral soap, seeing to it that cleansing solution never reaches
beater assembly at its inside.

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

NEVER USE SHARP METAL OBJECTS TO CARRY OUT THIS OPERATION. GOOD
WORKING OF A FREEZING PLANT MOSTLY DEPENDS ON CLEANING OF
CONDENSER.
