Zanussi ZRT318W user manual Care and cleaning, What to do if…, Defrosting of the refrigerator

Care and cleaning

Caution! Unplug the appliance before carrying out any maintenance operation.

This appliance contains hydrocarbons in its cool- ing unit; maintenance and recharging must there-

fore only be carried out by authorized technicians.

Many proprietary kitchen surface cleaners contain chem- icals that can attack/damage the plastics used in this ap- pliance. For this reason it is recommended that the out- er casing of this appliance is only cleaned with warm wa- ter with a little washing-up liquid added.

After cleaning, reconnect the equipment to the mains supply.

Defrosting of the refrigerator

Frost is automatically eliminated from the evaporator of the refrigerator compartment every time the motor com- pressor stops, during normal use. The defrost water drains out through a trough into a special container at the back of the appliance, over the motor compressor, where it evaporates.

It is important to periodically clean the defrost water drain hole in the middle of the refrigerator compartment channel to prevent the water overflowing and dripping onto the food inside. Use the special cleaner provided, which you will find already inserted into the drain hole.

Defrosting the freezer

A certain amount of frost will always form on the freezer shelves and around the top compartment.

Important! Defrost the freezer when the frost layer reaches a thickness of about 3-5 mm.

To remove the frost, do these steps:

1.Switch off the appliance.

2.Remove any stored food, wrap it in several layers of newspaper and put it in a cool place.

3.Leave the door open.

4.When defrosting is completed, dry the interior thor- oughly and refit the plug.

5.Switch on the appliance.

6.Set the temperature regulator to obtain the maxi- mum coldness and run the appliance for two or three hours using this setting.

7.Reload the previously removed food into the com- partment.

Important! Never use sharp metal tools to scrape off frost from the evaporator as you could damage it. Do not use a mechanical device or any artificial means to speed up the thawing process other than those recommended by the manufacturer. A temperature rise of the frozen food packs, during defrosting, may shorten their safe storage life.

What to do if…

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 crack- ing noise. It is natural, not dangerous physical phe- nomenon. This is correct.

•When the compressor switches on or switches off, you will hear a faint "click" of the temperature regula- tor. This is correct.
