HANDBOOKSTRUCTURE
This handbook is structurilized in sections, chapters and subchapters in order to consult it more
easily.
Section
A section is the part of handbook identifying a specific topic referred to a machine part.
Chapter
A chapter is that part of section describing a group or concept relevant to a machine part.
Subchapter
It is that part of a chapter detailing the specific component of a machine part.
It is necessary that each person involved in the machine running reads and clearly understands
those parts of the handbook of own concern, and particularly:
- TheOperatormust have alookatchaptersconcerning themachinestart-upandtheoperation
of machine groups.
-Askilledtechnicianemployedininstallation,maintenance,repair,etc.,must readallpartsof
this handbook.
ADDITIONALDOCUMENTATION

SAFETY
Whenusingindustrialequipmentandplants,onemustbeawareofthefactthatdrivemechanisms
(rotarymotion),highvoltagecomponents,aswellaspartssubjecttohightemperaturesmaycause
serious damages to persons and things.
Who is in charge of plant safety must be on the look-out that
- an uncorrect use or handling is avoided
- Safety devices must neither be removed nor tampered
- Only original spare parts are to be used especially as far as those components with safety
functions are concerned (ex.: protection microswitches, thermostats).
To achieve the above, the following is necessary:
- At working place an instruction manual relevant to the machine should be available.
- Such documentation must be carefully read and regulations must consequently be followed.
- Only adequately skilled personnel will have to be assigned to electrical equipment.
QUALIFICATIONOFTHESTAFF
Staff attached to the machine can be distinguished according to training and responsibility as
follows:
OPERATOR
- A person who has not necessarily a high technical knowledge, just trained for ordinary
operation of the machine, such as: startup, stop, filling, basic maintenance (cleanout, simple
blocking, instrumentation checkings, etc.).
SKILLEDENGINEER
-A personengangedon morecomplicatedoperations ofinstallation, maintenance, repairs,etc.
IMPORTANT!
Onemustbeonthelook-out that thestaffdoesnotcarryoutanyoperationoutsideitsownsphere
of konwledge and responsibility.
NOTE:
According to the standard at present in force, a SKILLED ENGINEER is who, thanks to
- training, experience and education,
- knowledge of rules, prescriptions and interventions on accident prevention,
- knowledge of machine operating conditions,
is able to realize and avoid any danger and has also been allowed by the person in charge of
plant safety to carry out all kinds of interventions.

1.2 INFORMATION ABOUT THE MACHINE
1.2.1Generalinformation
Masterchef machines produce ice cream and confectionery and they can work fruit and greens
in pieces.
This machine was not designed:
- to produce "pasta"
- to freeze water, i.e., to produce ice cream with high water contents
- to mix, work out, etc. explosives or substances prejudicial to the health.
OTTFREEZERrecommends toalwaysusehighqualityingredientsforconfectioneryproducts
in order to satisfy your customers, even the hardest-to-please ones. Any saving made to the
prejudice of quality will surely turn into a loss much bigger than the saving itself.
Bearing in mind the above statements, please take heed of the following suggestions:
zChoose high quality natural ingredients or buy them from reliable companies.
zClosely follow instructions given by your supplier.
zDo not alter your supplier's recipies, by adding, for instance, water or sugar.
zTaste your product before serving and start selling it if only entirely satisfactory.
zMake sure your staff always keeps the machine clean.
zHave your machine always serviced by companies authorized by OTT FREEZER.

- The machine may not be washed with any direct water spray.
1.4 NOISE
The continuous level of acoustic radiation pressure, which has been weighed and called A on
working place, turns to be lower than 70 dB(A), both by aircooled and by watercooled units.
1.5 STORING A MACHINE
The machine must be stored in a dry and dump-free place.
Before storing the machine, wrap it in a cloth in order to protect it against dust and else.
1.6 DISPOSAL OF PACKING STUFFS
When opening the packing crate, divide packing stuffs per type and get rid of them according
to laws in force in machine installation country.

MASTERCHEF

2. INSTALLATION
2.1 ROOM NECESSARY TO THE MACHINE USE
The machine may only run indoors.
The machine must be installed in lying flat, so that air can freely circulate all around.
Rooms fortheapproachtothemachinemustbeleftfreeinordertoenabletheoperator toact without
constraint and also to immediately leave working area, if need be.
Theminimumapproach roomtoworkingareashouldbeatleast 150cminconsiderationof space
taken by opened doors.
2.2 MACHINE LOCATION
The machine is provided with wheels for its easy location; two castors are provivded with
mechanical locks, which once engaged, lock the wheels and so keep the machine standstill.
2.3 MACHINES WITH AIRCOOLED CONDENSER
Machines with aircooled condenser must be installed no closer than 50 cm to any wall in order to
allow free air circulation around the condenser.
Frequently clean the floor beneath and near to the machine, to avoid that paper and else obstruct
a regular airflow. Further, condenser needs to be cleaned monthly, so eliminating dust, paper and
what else can obstruct it and affect a regular operation.
NOTE
An insufficient air circulation affects operation and output capacity of the machine.
2.3.1 Watersupplyconnectionforwash
Themachine must beconnectedto running waterwhichpressure must notbehigher than 0,8MPa
(8bar).
Byaircooledmachines,waterconnectionfordrinkingwater(formachinewash),markedbytheplate

We recommend to use rubberized canvas tubes with a working pressure up to 0,8 MPa (8 bar).
2.4.1 Watervalveadjustment
IMPORTANT
If water valve needs to be reset, such an operation must be carried out by skilled personnel, only.
Set water valve so that, with machine off no water comes out and lukeawarm water flows out
when on.

2.5 ELECTRICAL CONNECTION
Before connecting the machine to the mains, check that the voltage is the same as the one stated
on its plate.
Power cable by machines on 400 V, 50 Hz, threephase is made up of 5 wires: 3 wires for phases,
the blue one for neutral and the green/yellow one for earthing.
By machines with other voltages, power cable is made up of 4 wires, without the neutral one.
