3270360_GB

DISPOSAL

WASTE STORAGE

At the end of the product life, avoid release to the environment. The doors should be removed before disposal. Temporary storage of special waste is permitted while waiting for disposal by treatment and/or final collection. Dispose of special waste in accordance with the laws in force with regard to protection of the environment in the country of the user.

PROCEDURE FOR ROUGH DISMANTLING THE APPLIANCE

All couintries have different legislation; provision laid down by the laws and the authorised bodies of the countries where the demolition takes place are therefore to be observed. A general rule is to deliver the appliance to specialised collection and demolition centres. Dismantle the refrigerator grouping together the components according to their chemical nature. The compressor contains lubricating oil and refrigerant, which may be recycled. The refrigerator components are considered special waste, which can be assimilated with domestic waste. Make the appliance totally unusable by removing the power cable and any door locking mechanisms in order to avoid the risk of anyone being trapped inside.

DISMANTLING OPERATIONS SHOULD BE CARRIED OUT BY QUALIFIED PERSONNEL. THE SAFE DISPOSAL OF WASTE FROM ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE

DIRECTIVE 2002/96/EC) Do not dump pollutant material in the environment. Dispose of it in compliance with the relevant laws.

Under the WEEE (Waste Electrical and Electronic Equipment) Directive 2002/96/EC, when scrapping equipment the user must dispose of it at the specific authorised disposal centres, or reconsign it, still installed, to the original seller on purchase of new equipment. All equipment which must be disposed of in accordance with the WEEE Directive 2002/96/EC is marked with

a special symbol

The improper disposal of Waste Electrical and Electronic Equipment is liable to punishment under the relevant laws in the countries where the offence is committed.

Waste electrical and Electronic Equipment may contain hazardous substances with potential harmful effects on the environment and human health. You are urged to dispose of them properly.

3270360_GB

OPERATION

GENERAL DESCRIPTION

The blast chiller is a chilling machine capable of cooling the temperature of a freshly cooked product up to +3°C (positive chilling) and up to -18°C (negative chilling), in order to conserve it for a long period of time without altering the organoleptic characteristics. Machine capacity as to the quantity to be cooled depend on the model purchased.

SETTING UP

Before setting to operation thoroughly clean the cooling cabinet with a suitable detergent or sodium bycarb dissolved in lukewarm water. Clean the appliance inside to remove any condensate caused by the Manufacturer's final testing.

Cooling and freezing speed depends on the following factors:

a) container shape, type and material; b) whether container lids are used; c) foodstuff features (density, water contents, fat contents); d) starting temperature; e) thermal conduction in side the foodstuffs.

Positive /Negative quick cooling time depends on type of foodstuffs to be processed. In general the programmes the machine is equipped with are based on the chamber temperature management, the fan speed and the chilling time, in any case never exceed 3.6kg of load (for GN1/1, EN1/1 or 60x40 pans) or 7.2kg of load (for GN2/1, EN2/1 or 60x80 pans) and a thickness of 50mm in negative chilling phase and 80mm in positive chilling phase (table 2). Check that the positive chilling programme, up to +3°C at the product core, does not take more than 90 minutes and that the negative chilling programme, up to -18°C at the product core, does not take more than 4 hours. We recommend pre-chilling the work chamber before beginning with a chilling programme and not covering the food during the programme in order not to increase times. We recommend using the core probe in order to have the exact core temperature reading. Do not stop the cycle before reaching a temperature of +3°C during positive quick cooling and -18°C during negative quick cooling.

TEMPERATURES

Do not leave the cooked products that are to be chilled/frozen at room temperature. Avoid humidity losses, which will be detrimental to the conserved fragrance of the product. We recommend beginning the chilling/freezing programme as soon as the preparation or co oking phase has ended, being careful to insert the product into the equipment at a temperature no lower than +70°C. The cooked product can enter the equipment even at very high temperatures, greater than +100°C, as long as the chamber has been pre-chilled. In any case it should be taken into consideration that the programme reference times always start from a temperature of +90°C, in positive chilling from +90°C to +3°C and in negative chilling from +90°C to -18°C.

LENGTH

Cooled or frozen processed foodstuffs may be stored in a refrigerator for 5 days of processing with no quality alterations. For best results we recommend keeping temperature constant throughout the storing (0°C to 4°C), according to the various commodities. Storing time may be increased to approx. two weeks by using vacuum processing. After a negative quick cooling cycle, foodstuffs may be stored safely for 3 to 18 months, according to the type of foodstuff processed. We strongly recommend keeping storing temperature at -20°C or below. The cooled product should be wrapped in a specific film for foodstuffs (better still, vacuum stored) and provided with a sticker reporting the content [A], date of processing [B] and expiry date [C] written in permanent type ink.

MAINTENANCE

MAINTENANCE AND CLEANING

CLEANING THE CABINET

Clean inside the cooling cabinet daily. Both the cabinet and all the internal components have been designed and shaped to allow washing and cleaning all parts easily. Before cleaning, defrost the appliance and remove the internal drain. Disconnect the master switch. Clean all components (stainless-stell, plastic or painted parts) with lukewarm wa ter and detergent. Then rinse and dry without using abrasives or chermical solvents.

Do not wash the appliance by spraying high-pressure water on the machine.

Do not rinse with sharp or abrasive tools, especially the evaporator.

You may clean inside the evaporator after loosening the knobs and rotating the protection component.

Wash the door gasket with water. Accurately dry with a dry cloth. We recommend wearing protecting gloves throughout the operations.

3270360_GB

Hand-wash the probe using lukewarm water and a mild detergent or products with biodegradability higher than 90%. Rinse with water and sanitary solution. Do not use detergents containing solvents (such as trichloroethylene, etc) or abrasive powders ATTENTION: do not use hot water to wash the probe.

CLEANING THE AIR CONDENSER

The air condenser should be kept clean to ensure the appliance's p erformance and efficiency, as air should freely circulate inside the appliance.

The condenser should therefore be cleaned every 30 days, using non-metal brus hes to remove all dust and dirt from condenser blades.

Access to the condenser is from the front.

Unhook the front guard, pulling it towards you.

STAINLESS-STEEL MAINTENANCE

By stainless steel we mean INOX AISI 304 steel. We recommend following the instructions below for the maintenance and cleaning of stainless-steel parts. This is of the utmost importance to ensure the non-toxicity and complete hygiene of the processed foodstuffs. Stainless-steel is provided with a thin oxide layer which prevents it from rusting. However, some detergents may destroy or affect this layer, therefore causing corrosion. Before using any cleansing product, ask your dealer about a neutral chlorine ss cleansing product, as to avoid steel corrosions. If the surface has been scratched polish it with fine STAINLESS-STEEL wool or a synthetic-fibre abrasive sponge. Always rub in the direction of the silking. WARNING: Never use iron wool for cleaning STAINLESS STEEL. Furthermore, avoid leaving iron wool on the appliance surface as tiny iron deposits may cause the surface to rust by contamination and affect the hygiene of the appliance.

3270360_GB

DISCONTINUED USE

Should the machine be disconnected over long periods, follow the instructions below to maintain the appliance in good condition:

Turn the mains switch OFF.

Disconnect the plug.

Empty the appliance and clean it in accordance with the instructions given in the chapter "CLEANING". Leave the door ajar to prevent a bad smell. Cover the compressor unit with a nylon cloth to protect it from dust.

In case of appliances with remote control, if you decide to turn it off, remember to put the switch off also in the remote control..
