GB - 16
Installation, ordinary and extra-ordinary maintenance (for
example, cleaning and maintenance of the refrigerating system), must
be performed by specialised and authorised technical personnel with a
sound knowledge of the refrigeration and electrical systems.
1.4. PREREQUISITES SUPPLIED BY THE CUSTOMER
Provide a high sensitivity differential magnetothermic switch (30 mA).
Provide a wall socket of the type used in the country in which the ma-
chine is operated.
Verify that the surface on which the machine rests is level.
In the case of machines with water condenser or with equipment with
direct humidity control, provide connection to a water system.
1.5. INSTRUCTIONS ON REQUESTS FOR INTERVENTION
Often operating difficulties are a result of ordinary causes which are al-
most always remediable inhouse, therefore, before requesting assistance
from a technician, perform the following simple verifications:
IF THE MACHINE STOPS OPERATING:
- Check that the plug is inserted correctly in the electrical socket.
IF THE CABINET TEMPERATURE IS INSUFFICIENT:
- Verify that this is not being influenced by a heat source;
- Verify that the doors close perfectly;
- Verify that the condenser filter is not blocked;
- Verify that the ventilation grills of the control panel are not obstructed;
- Verify that the items inside the cabinet are not obstructing ventilation.
IF THE MACHINE IS NOISY:
- Verify that there is no loose contact between the machine and another object;
- Verifty that the machine is perfectly level;
- Verify that the screws (at least those visible) are tightly closed;
If the defect persists after the above verifications, request technical as-
sistance, indicating:
- The nature of the defect;
- The code and serial number of the machine appearing on the specifica-
tions plate.
1.6. INSTRUCTIONS FOR SPARE PARTS
ORIGINAL SPARE PARTS are recommended.
The manufacturer does not accept any responsibility for the use of non-
original parts.
2. TECHNICAL DATA
The technical data plate is located outside on the side or at the rear, and
inside the motor compartment.
2.1. NOISE LEVEL
Leq at the noisiest point at 1 m in operating condition < 70 dB (A)
Lpc at 1 m in operating conditions < 130 dB (C)
TESTING ENVIRONMENT
Testing has been performed in a rectangular showroom with no sound
absorption.
Significant obstacles were absent in the area surrounding the machine.
REFERENCE REGULATIONS
Noise testing was performed in compliance with Legislative Decree 277
and in accordance with methods described in ISO 230-5, in order to ob-
tain the data required by EEC Directive 89/392.
OPERATING CONDITIONS OF THE MACHINE
Testing was performed under the most severe condition which corre-
sponds to the start-up phase called “PULL DOWN”.
2.2. MATERIALS AND FLUIDS USED
The materials used comply with Legislative Decree of 25 July 2005, No.
151 in enactment of Directives 2002/95/EC, 2002/96/EC and 2003/108/
EC, relating to the reduction in the use of hazardous substances in elec-
trical and electronic equipment, as well as to waste disposal
3. OPERATION
3.1. APPLICATIONS, PURPOSE, FORESEEN AND UN-
FORESEEN USE, AUTHORISED USE
Our refigerators are agroindustrial machines (EC regulation No.
1935/2004), intended for foodstuffs.
The machines are designed with the appropriate equipment to guarantee
the health and safety of the user.
APPLICATION OF THE BLAST CHILLER-FREEZER:
The blast chiller-freezer is a machine which rapidly lowers the tempera-
ture of cooked or raw foods, in order to maintain unaltered the orga-
noleptic properties (chemical-physical and nutritional) of these foods.
Cooling or freezing time, in function with the type or types of
elements present in a cooked dish (density, portions), is a vari-
able parameter not easy to stabilise. The declared performanc-
es have been obtained with potato puree, deposited in GN1/1
H=40 steel baking trays. The thickness of the puree contained
in the trays is 25mm.
BLAST CHILL TEMPERATURE CYCLE:
This cycle enables a rapid lowering of the temperature of the cooked food
(from +90 to +3°C in 90 minutes) to avoid it remaining within the critical
temperature range of +10°C to +65°C.
The cooked and blast chilled food can be stored in the refrigerator for
up to 5 days.
SHOCK FREEZE TEMPERATURE CYCLE:
Shock freezing (from +90°C to -18°C) prevents the formation of macro-
crystals of ice in the food, which would result in a loss of liquids and
vitamins.
This cycle is suitable for cooked and raw food and conserves these food-
stuffs for up to 2 months and 12 months respectively.
CONSERVATION CYCLE:
At the end of every blast chill or shock freeze cycle the machine pro-
vides for a conservation cycle during which the equipment functions as
a normal refrigerator and the duration of which is to the discretion of
the user.
FOODSTUFFS STORAGE
For the best performance, the following indications should be observed:
Conservation cycle:
- Do not introduce inside the machine hot foods or uncovered liquids;
- Wrap or protect foodstuffs, in particular if they contain aromas;
- Arrange the foodstuffs inside so as not to limit air circulation, avoiding
placing on the racks papers, cartons, boards, etc. which may obstruct the
passage of air;
- Avoid as far as possible opening the door frequently or for lengthy
periods of time.
Blast chill cycle / shock freeze
- Do not open the door once the cycle has commenced and until the cycle
has terminated;
- Avoid wrapping, protecting or closing containers with lids or insulating films;
- Do not use trays or containers higher than 65mm;
- Do not stack foodstuffs;
- Use aluminium or stainless steel containers.
3.2. DANGEROUS AREAS, RISKS, HAZARDS AND UNA-
VOIDABLE RISKS
The refrigerator equipment has been designed and manufactured with
the appropriate devices to guarantee the health and safety of the user
and does not contain dangerous edges, sharp surfaces or protruding ele-
ments.
The stability of the machine is guaranteed even when the doors are open;
however, do not pull on the doors.
In the case of refrigerators with drawers, do not open more than one
drawer at a time and do not lean or sit on an open drawer, so as to avoid
overturning or damaging the refrigerator.
N.B.: In refrigerators with glass doors do not extract more than one
