4. SAFETY

iIt is recommended to carefully read the

instructions and warnings contained in this manual before using the appliance. The information contained in the manual is fundamental for the safety of use and for machine maintenance.

! Keep this manual carefully so that it can be

consulted when necessary.

i The electric plant has been designed in

compliance with the IEC EN 60335-2-24 Standard.

, Specific adhesives highlight the presence of

mains voltage in the proximity of areas (however protected) with risks of an electrical nature.

! Before the connection, ensure the presence of

an omnipolar switch with minimum contacts opening equal to 3 mm in the mains power supply upstream from the appliance (requested for appliances supplied without plug to connect to the fixed plant).

In the design and construction phase, the manufacturer has paid particular attention to the aspects that can cause risks to safety and health of persons that interact with the appliance.

Carefully read the instructions stated in the manual supplied and those applied directly to the machine, and particularly respect those regarding safety.

Do not tamper or eliminate the installed safety devices. Failure to comply with this requisite can lead to serious risks for personal health and safety.

It is recommended to simulate some test manoeuvres in order to identify the controls, in particular those relative to switch-on and switchoff and their main functions.

The appliance is only destined for the use for which it has been designed; any other use must be considered improper.

iThe manufacturer declines all liability for any

damage to objects or injury to persons owing to improper or incorrect use.

ENGLISH

i All maintenance interventions that require

precise technical skill or particular ability must be performed exclusively by qualified staff.

! When using the appliance, never obstruct the

air inlet when the appliance is on, so as not to compromise its performance and safety.

4.1. Safety Devices

During the running of appliance, some control devices may activate and govern the correct running of the machine. In other cases, they may deactivate parts or the whole machine, to put the appliance in safe conditions. Main controls are described below.

Door micro switch

If the door is opened, the magnetic switch placed on the control board opens and, during blast-chilling or shock-freezing, evaporator fans go off and a warning message appears on the display at the same time. This condition may also be determined when the door is not perfectly aligned to or near the control board: in this case with machine in STOP phase, cycle start-up is prevented, apart from start-up of the defrosting cycle.

Protective Fuses

Some protection fuses in the general power supply line are activated in case of overload.

! Never stretch the power cable.

In order to guarantee hygiene and protect the foodstuffs from contamination, the elements that come into direct or indirect contact with the foodstuffs must be cleaned very well along with the surrounding areas. These operations must only be performed using detergents that can be used with foodstuffs, avoiding inflammable products or those that contain substances that are harmful to personal health.

In the case of prolonged inactivity, as well as disconnecting all the supply lines, it is necessary to accurately clean all internal and external parts of the appliance.

High condensation temperature alarm

In the event of room conditions or functional failures, which cause the condenser to exceed the maximum temperature value, an alarm is triggered and stops the machine running. The machine can be run when an acceptable temperature value is reset.

Evaporator Fan Micro switch

If the deflector is opened to inspect the evaporator or fans this micro switch positioned on the evaporator deflector deactivates machine functioning. Closure of the deflector with the successive disappearance of the alarm on the display, restores normal machine functioning.

5. USE AND FUNCTIONING

5.1. Description of the Functioning Cycles

The following are brief descriptions and types of operating cycles.

Temperature Blast Chilling

This cycle allows a reduction in temperature in the product core from +90°C to +3°C as quickly as possible and within a MAX time of 90 minutes. The cycle ends when the value +3°C, read by the needle probe, is reached.

Time Blast Chilling

This cycle allows a reduction in temperature in the product core from +90°C to +3°C during the set time: we remind you that it is advisable to run some previous testing temperature cycles in order to determine the necessary time for a correct product blast chilling process. Do not forget that acquired times have to be considered valid for exclusive use of the same type of product and in the same quantities per cycle.

Temperature Shock Freezing

This cycle allows a reduction in temperature in the product core from +90°C to -18°C in the quickest time possible and within a MAX time equal to 270 minutes. The cycle ends when the value -18°C, read by the needle probe, is reached.

Time Shock Freezing

This cycle allows a reduction in temperature in the product core from +90°C to -18°C during the set time: we remind you that it is advisable to run

ENGLISH

some previous testing temperature cycles in order to determine the necessary time for a correct product blast chilling process. Do not forget that acquired times have to be considered valid for exclusive use of the same type of product and in the same quantities per cycle.

Preservation

At the end of each cycle as described above, either temperature or time cycle, the preservation cycle will be started automatically, with no time limit. The freezer temperature will refer to last cycle, just concluded:

Ø + 3°C for blast chilling Ø -25°C for shock-freezing

Warning: use of this cycle is recommended only for short periods prior to storage of the product in a storage unit or in case of emergency, so as to avoid such a limited use of a machine with such high potential.

Defrosting

The frost forming on the evaporator following the deposit of humidity from the product can jeopardise the correct functioning of the appliance. A defrosting cycle must be carried out to restore full functionality.

Defrosting is performed by forced ventilation using the evaporator fan. The cycle can be performed with the door open or closed and can also be interrupted at any time.
