Helpful hints and tips

Normal Operating Sounds

• You may hear a faint gurgling and a bubbling

sound when the refrigerant is pumped

through the coils or tubing. This is correct.

• When the compressor is on, the refrigerant is

being pumped around and you will hear a

whirring sound and a pulsating noise from

the compressor. This is correct.

• The thermic dilatation might cause a sudden

cracking noise. It is natural, not dangerous

physical phenomenon. This is correct.

• When the compressor switches on or

switches off, you will hear a faint "click" of

the temperature regulator. 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 temper-

ature and the appliance is fully loaded, the

compressor may run continuously, causing

frost or ice on the evaporator. If this happens,

set the Temperature Regulator toward warm-

er settings to allow automatic defrosting and

so a saving in electricity consumption.

Hints for freezing

To 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 rating plate;

• the freezing process takes 24 hours. No fur-

ther food to be frozen should be added dur-

ing this 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 to make

it possible subsequently to thaw only the

quantity required;

• wrap up the food in aluminium foil or poly-

thene and make sure that the packages are

airtight;

• do not allow fresh, unfrozen food to touch

food which is already frozen, thus avoiding a

rise 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 re-

moval from the freezer compartment, can

possibly cause the skin to be freeze burnt;

• it is advisable to show the freezing in date on

each individual pack to enable you to keep

tab of the storage time.

Hints for storage of frozen food

To obtain the best performance from this appli-

ance, you should:

• make sure that the commercially frozen food-

stuffs were adequately stored by the retailer;

• be sure that frozen foodstuffs are transferred

from the foodstore to the freezer in the short-

est possible time;

• not open the door frequently or leave it open

longer than absolutely necessary;

• once defrosted, food deteriorates rapidly and

cannot be refrozen;

• do not exceed the storage period indicated

by the food manufacturer.

ing must therefore only be carried out by au-

thorized technicians.

Periodic cleaning

The equipment has to be cleaned regularly:
