• When the compressor is on, the refrigerant is being pumped around and you will hear awhirring sound and a pulsating noise from the compressor. This is correct.• The thermic dilatation might cause a sudden cracking noise. It is natural, not dangerousphysical phenomenon. This is correct.Hints for energy saving• Do not open the door frequently or leave it open longer than absolutely necessary.• If the ambient temperature is high and the Temperature Regulator is set to low tempera-ture and the appliance is fully loaded, the compressor may run continuously, causingfrost or ice on the evaporator. If this happens, set the Temperature Regulator towardwarmer settings to allow automatic defrosting and so a saving in electricity consump-tion.Hints for fresh food refrigerationTo obtain the best performance:• do not store warm food or evaporating liquids in the refrigerator• do cover or wrap the food, particularly if it has a strong flavour• position food so that air can circulate freely around itHints for refrigerationUseful hints:Meat (all types) : wrap in polythene bags and place on the glass shelf above the vegetabledrawer.For safety, store in this way only one or two days at the most.Cooked foods, cold dishes, etc..: these should be covered and may be placed on any shelf.Fruit and vegetables: these should be thoroughly cleaned and placed in the special draw-er(s) provided.Butter and cheese: these should be placed in special airtight containers or wrapped in alu-minium foil or polythene bags to exclude as much air as possible.Milk bottles: these should have a cap and should be stored in the bottle rack on the door.Bananas, potatoes, onions and garlic, if not packed, must not be kept in the refrigerator.Hints for freezingTo help you make the most of the freezing process, here are some important hints:• the maximum quantity of food which can be frozen in 24 hrs. is shown on the ratingplate;• the freezing process takes 24 hours. No further food to be frozen should be added duringthis period;• only freeze top quality, fresh and thoroughly cleaned, foodstuffs;• prepare food in small portions to enable it to be rapidly and completely frozen and tomake it possible subsequently to thaw only the quantity required;• wrap up the food in aluminium foil or polythene and make sure that the packages areairtight;• do not allow fresh, unfrozen food to touch food which is already frozen, thus avoiding arise in temperature of the latter;• lean foods store better and longer than fatty ones; salt reduces the storage life of food;• water ices, if consumed immediately after removal from the freezer compartment, canpossibly cause the skin to be freeze burnt;Helpful hints and tips 31
