3 TRANSPORTATION AND PLACING OF THE
APPLIANCE
3.1 INSTRUCTIONS FOR PREVENTING INJURIES
Pay due attention to legally required safety measures.
At work wear suitable clothing. Do not wear ties, jeweller’s chains or belts,
which could get caught in the machine.
Do not shift or dislocate the safety switches or protective parts.
Make sure that the lifting device is in good condition and that its load capacity
exceeds the weight of the appliance (refer to the technical specifications data
sheet).
Lift the appliance following the instructions for its use and maintenance. Pay
attention to the handling and handgrip locations. The use of a suitable lifting
device is recommended.
While lifting or moving the appliance do not stand under the machine.
Do not turn the appliance after holding the cables or the water hose has lifted it.
If you have to attend to any work higher up above the appliance, you should use
a suitable ladder and not the appliance for support.
3.2 UNLOADING THE APPLIANCE FROM THE LORRY
Required devices are a hand lift for pallets and a forklift truck with load capacity
of at least 1,200 kg.
Lift the crate containing the appliance using the hydraulic palette lift and move it
as close to the open side of the lorry as possible.

13
Remove the hand lift from underneath and handle the crate with the forklift
truck. Make sure that the weight is focused on the holding points.
Remove the crate from the lorry with the forklift truck in reverse gear as soon as
the crate is moved out of the lorry, and lower the crate to the minimal height of
around 30 cm.
Slowly and carefully place the box containing the appliance in its place. To
move the appliance around on the premises use wheels, which are supplied
with the appliance.
3.3 UNPACKING OF THE APPLIANCE
Upon the delivery check if the crate was not damaged during transportation.
First the appliance is fixed on the pallet with two paking strips and then is
placed the carton box which is fixed to the pallet with two paking strip too.
When the machine is unpacked, make sure that the packaging is disposed in a
suitable manner and in compliance with standards on environmental safety.
3.4 PLACING THE APPLIANCE ON THE GROUND
Place the machine on a level solid non-combustible surface with an adequate
strength of at least 600 kg per m² for the weight of the machine, and position the
appliance at least 60 cm away from the wall or other objects. Leave enough
space in front of the appliance to ensure comfortable access and work with the
appliance.

While placing the appliance in position, block the front wheels (by pressing the
brake), which will ensure that the appliance will not be able to move.
4 REQUIREMENTS AND CONDITIONS FOR
NORMAL OPERATION OF THE APPLIANCE
Before connecting the appliance to electricity supply, the operator must make
sure that environment requirements have been met: the temperature and
humidity of the air must be appropriate and the water supply and electricity
networks comply with all requirements for normal operation of the appliance.
When the characteristics of either the water supply or electricity network fail to
meet the requirements for normal operation, the machine must not be
connected to power supply.
4.1 ENVIRONMENTAL CONDITIONS
Prior to connecting the appliance, the temperature and the humidity of the
environment, in which the appliance will be operated, must be assessed and
checked.
If room temperature drops under 0 ºC (273K), water must be released from the
condenser.
4.2 WATER SUPPLY REQUIREMENTS

Prior to connecting the appliance to the power source, the temperature,
pressure and water flow from the water supply network must be checked.
Permitted water temperature and water pressure from the water supply network:
Water supply must be checked for all conditions that are required for alimentary
use.
Low water pressure causes the cooling system to function improperly. The
cooling gas does not condense, thus causing the compressor to overload. In
such cases, the safety pressure valve kicks in and switches off the compressor.
The results of mixture treating and ice cream production when the water
pressure is too low are not as good as when the water pressure is normal.
The maximum presence of chlorides in water is 120 ppm. Exchangers are not
suitable for the use of salt water.
4.3 ELECTRICITY SUPPLY REQUIREMENTS
Prior to connecting the appliance to the power source, the voltage and the
maximum power current allowed in the network must be checked and the
appliance must be protected externally with FUSES and the MAIN SWITCH.
Permitted voltage of three-phase appliances (400/50/3):
Permitted voltage of three-phase appliances (230/50/3):
Permitted voltage of one-phase appliances (230/50/1):
Permitted voltage of one-phase appliances (208-220/60/3):
Permitted voltage of one-phase appliances (208-220/60/1):
The diameter of each phase conductor must be of an appropriate dimension
(corresponding to the power of the fuses).

5 CONNECTING THE APPLIANCE
5.1 INSTRUCTIONS FOR PREVENTION OF INJURIES
When the characteristics of either the water supply or electricity network fail to
meet the requirements for normal operation, the machine must not be
connected to the power supply.
It is forbidden to connect the appliance to the power source when the floor
around the appliance is wet.
It is forbidden to connect the appliance to the power source if any of the side
panels and the cover is missing.
5.2 CONNECTING THE APPLIANCE TO THE WATER SUPPLY
The water supply regulation valve is connected to the WATER SUPPLY PORT.
The water outlet pipe is connected to the WATER OUTLET PORT and to the
outlet pipe leading to the drain. All these terminals have a diameter of 3/4" and
are located on the backside of the machine.
To connect the appliance to the water supply (water supply port) and the outlet
to the drain (water outlet port), use pipes capable of withstanding 1MPa and
measuring at least ½” in diameter (make sure upon the delivery that the pipes
are supplied with the appliance).




17
If the appliance is meant to be used in areas with two separate water supplies,
two separate water connectors are built in it, one for each: a DRINKING
WATER SUPPLY PORT and a COOLING WATER SUPPLY PORT
(condenser).
The valve belonging to the cooling water supply must not be connected to the
DRINKING WATER SUPPLY PORT.
The valve belonging to the drinking water supply may be connected to the
COOLING WATER SUPPLY PORT and/or to the DRINKING WATER SUPPLY
PORT.
The valve should be opened after the appliance has been connected to the
water supply system.
5.3 CONNECTING THE APPLIANCE TO THE POWER SUPPLY
Only appropriately trained technicians are allowed to connect the appliance to
the electrical current. They must follow installation instructions and observe the
occupational safety regulations applying in the country in which the appliance is
being installed. They must read the instructions carefully and above all
thoroughly familiarize themselves with the sections on REQUIREMENTS AND
CONDITIONS FOR NORMAL OPERATION OF THE APPLIANCE and the
machine’s electrical circuit scheme.
Before connecting the appliance, all attachments that might have become loose
during transportation must be checked. Attachments that may have become
loose or disconnected must be screwed back on and tightened.

Connecting instructions for five-vein cable (three-phase appliances – 400/50/3):
A test start-up of the appliance is carried out by an appropriately trained
electrician who has also connected the machine so as to make sure that it is
properly connected (see the section on MAINTENANCE).
If the machine has been connected correctly, the mixer in the mixture-treating
cylinder will rotate anti - clockwise.
Should the mixers rotate in the wrong direction, it is necessary to change the
connecting position of any of the two phases.
Production cylinder mixer, installed in appliances with built-in inverter, will rotate
in the correct direction regardless of the connecting position of either of the
phases so it is necesary check the direction of the mixer in the cooking cylinder.
The mixer must rotate in clockwise direction.
Should the mixers rotate in the wrong direction, it is necessary to change the
connecting position of any of the two phases.
After connecting the appliance to the electricity network, appropriately trained
electrician must also control the power consumption. The current must not
exceed the maximum allowed on the identification plate or sticker (see the
section GENERAL FEATURES AND SPECIFICATIONS).
6 OPERATING THE APPLIANCE
The user operates the appliance standing in front of appliance. This position
allows user to handle the control panel, the safety switch and the water flow
regulation valve (shower).
The appliance must be always under users control during operation.
