Installation and connection

Choosing the site

- Always place the refrigerator in a dry place with satisfactory ventilation. Never expose it to direct sunlight or install it outdoors. Depending on its climate class (stated on the nameplate inside the refrigerator compartment), the appliance can be used in different temperature conditions:

Class Ambient temperature

SN (Subnormal) from +10°C to +32°C

N (Normal) from + 16°C to + 32°C

ST (Subtropical) from + 18°C to + 38°C

T (Tropical) from + 18°C to + 43°C

• Never place the refrigerator close to heat sources. If this is unavoidable, a suitable insulating panel must be used to allow the appliance to function properly. Otherwise, place the appliance at least 3 cm from electric or gas cookers and at least 30 cm from combustion or radiation heating systems.
• To allow proper cooling of the condenser, the refrigerator must not be placed too close to the wall. If the refrigerator is installed underneath a wall cupboard, the distance between the two must be at least 5 cm.
• Take care not to scratch or damage the floor when installing the appliance on parquet or linoleum. If necessary, when positioning slide the refrigerator over pieces of wood or a mat to the point decided for connection to the electrical mains.

Positioning and levelling the appliance

Place the fridge on a stable and level floor. In case the floor is not perfectly level, use the two adjustable feet on the front part of the fridge. To ensure major stability, easier movement and a correct positioning of the product, two additional wheels are present at the rear. In any case

we recommend moving the fridge very carefully in order to avoid floor damage (especially in case of wooden floor).

Electrical connection

Before switching the refrigerator on for the first time, leave it vertical for at least two hours. Then connect the appliance's power supply lead to a mains socket with earth contact, installed in accordance with electrical safety regulations. The rated voltage and frequency are stated on the nameplate. The appliance must be connected to the electrical mains and earthed in compliance with the relevant regulations and requirements. The appliance is able to withstand short fluctuations in voltage of no more than 15% less or 10% more than the rated voltage stated on the nameplate. If the power supply lead has to be replaced, this operation must only be carried out by a qualified technician. The socket must be accessible after the appliance has been placed.

Before using for the first time

• Remove any exterior and interior packaging materials completely, including the adhesive strips.
• Before it is connected to the mains, the unit must be thoroughly checked for transport damage, including its power cord.
  – Clean the unit as described in the section Maintenance and Cleaning.
• To ensure proper functioning, wait for around 2 hours before connecting the unit and switching it on once it has been positioned.
• When the unit is first switched on, a slight smell may be noticed. However, this will disappear once the cooling process has begun.

Arranging foods inside the refrigerator compartment

- Arrange the foods on the various shelves, taking care that they have an airtight wrapping or cover. This precaution will:

• conserve foods' fragrance, moisture and freshness;
• prevent the cross-contamination of foods with different aromas and tastes;
• prevent the humidity level inside the refrigerator becoming too high because of the normal breathing of food (especially fresh fruit and vegetables). In some operating

conditions (rise in ambient temperature and humidity, more frequent opening of the door) this might cause condensation to form on the shelves.

• Use only containers approved for food storage. Always allow hot foods and drinks to cool to room temperature before placing them inside the refrigerator.
• Never store explosive substances in the appliance and only store high-alcohol drinks firmly sealed and vertical.

Setting and selecting the operating temperature

• The knob in the top right-hand corner of the refrigerator is used to set the operating temperature both in the refrigerator and in the freezer.
• When the knob is turned to 0 ("stop"), the appliance is switched off.
• The operating settings are from 1 to 7.
• There is no direct correspondence between the setting chosen and the temperature in the two sections of the appliance. Increasing the setting number reduces the temperature inside the appliance. Only use the highest settings (6-7) if absolutely necessary: with these settings, the temperatures inside the refrigerator compartment may be close to 0°C and electricity consumption will be higher. In normal operating conditions, a medium-low setting (2-3) is recommended. This will provide effective storage of the fresh foods in the refrigerator compartment and of the frozen foods in the freezer compartment.

Important: Changes in weather conditions (temperature and humidity) and the frequency with which the doors of the two separate compartments are opened may affect the refrigerator's operating temperatures.

Setting and selecting the freezer operating temperature

24 hours before freezing a large amount of fresh foods turn the thermostat to a setting between 5 and 7. After the 24 hours have passed, insert the fresh foods and turn the thermostat knob to the setting of your choice.

Important: Changes in weather conditions (temperature and humidity) and the frequency with which the door is opened affect the refrigerator's operating temperatures.

Freezing foods

- For proper storage and freezing, fruit and vegetables should be packed in portions of not more than 1 kg and meat and fish up to a max. of 2kg. Small packages of food freeze more quickly, giving better conservation of their nutrients and flavour, even after thawing and preparation.

• Use only freezer bags, aluminium film, food-approved polyethylene film and freezer containers. Do not use paper bags, non food-approved cellophane bags, shopping bags or used freezer bags.
• Pack foods in airtight packs and try to expel all the air. If using bags, close the packs with the elastic bands or plastic-coated wire strips provided.
• Always cool hot foods to room temperature before placing them in the freezer and do not allow frozen foods to touch fresh foods for freezing.
• Always mark packs with the date of freezing, quantity and type of food and make sure that foods are fresh and in good condition.

Storing frozen foods

• When purchasing frozen foods, always take care that the pack is not damaged, that the product is not past its sell-by date and that the thermometer of the freezer in which the products are displayed for sale does not show a temperature above -18°C. Also note the temperature advice, storage period and modes of consumption stated by the producer.
• Purchased foods should also be protected using suitable insulated containers during transportation to eliminate the risk of thawing. An increase in temperature might reduce their storage life and adversely affect their quality.
• Do not purchase frozen foods which are carrying too much frost; they might already have been thawed.

Thawing frozen foods

• Partially thawed foods should be eaten as soon as possible. Low temperatures preserve foods but they do not destroy the micro-organisms which are activated after thawing, which may cause the stored foods to deteriorate. If thawed foods smell and look normal, they can be cooked and if required re-frozen once they have cooled.
• Depending on their type and intended use, frozen foods can be thawed correctly at room temperature, in the refrigerator, in an electric oven (conventional or fan), or in a microwave oven using the relevant function.

Making ice-cubes

Fill the tray provided 2/3 full of water or any other liquid you wish to freeze. Place it in the freezer compartment, making sure that its bottom is dry so that it will not stick to the shelf of the compartment. To detach the ice-cubes, twist the tray slightly or place it under running water for a few seconds.

Maintenance and Cleaning

Defrosting the refrigerator compartment

The refrigerator compartment has automatic defrosting. During normal operation of the refrigerator, frost forms on its back wall when the compressor is working and dissolves when it is not in operation. When the compressor is not working, the frost which has built up on the

back wall melts and the water flows into the opening provided in the bottom of the body of the refrigerator. From here, it flows into the tray on the compressor, where it evaporates.

Warning: the amount of ice which forms on the back wall may vary with changes in weather conditions (temperature and humidity), the frequency with which the door is opened, the appliance's operating temperatures and the amount of fresh foods stored inside (especially fruit and vegetables).

Defrosting the freezer

The freezer compartment has to be defrosted manually. When the thickness of frost or ice on the shelves exceeds 2 cm, the freezer should be defrosted. A few hours before defrosting, use the knob provided to set the thermostat on 7 in order to further lower the temperature of the frozen foods. Then turn the knob to the 0 (stop) setting and disconnect the plug from the electrical mains. Remove the frozen foods from the freezer compartment and protect them from thawing while cleaning.

Cleaning the refrigerator

• Before cleaning, disconnect the plug from the electrical mains. Clean the outside using only water and a gentle liquid detergent or an ordinary detergent for washable surfaces (such as a window-cleaning product). Never use products containing abrasives or substances which may attack the lacquered or painted parts, acids or chemical solvents. Use a sponge or a soft cloth.
• Do not use steam cleaners to clean the inside;
• Remove the shelves and accessories, taking care not to apply excessive force when removing. Never wash removable plastic parts in the dishwasher; use only warm water and washing-up liquid or water and vinegar. Take care not to wet the electrical lighting components with water or detergents.
• Clean the gaskets with warm water and then dry.
• To allow the refrigerator to operate at full efficiency, periodically also clean the condenser on the rear with a brush or a vacuum cleaner.
  • Also make a periodic check on the tray above the compressor, and clean it if necessary.

Switching off the refrigerator

If the refrigerator is to be out of use for some time, turn the thermostat knob to 0 (stop). Then empty the compartments, disconnect the appliance from the electrical mains, and once it has defrosted dry any residual moisture which has collected. Leave the door ajar to prevent the humidity and trapped air from creating unpleasant smells.

Replacing the refrigerator light bulb

Before changing the bulb, make sure that the light has not stopped working simply because the part inside the lamp socket has become loose. In all cases, whether you wish to check that the

socket is connected correctly or change the bulb, for safety reasons the plug must be removed from the power socket.

1. Unplug the unit from the power supply.
2. Remove the refrigerator light diffuser cover.
3. Replace the light bulb with a new 10 watt (max) screw cap (SES) bulb.
4. Assemble the light diffuser cover and after waiting 5 minutes plug the unit.
