Warranty Information

This guarantee is valid for twenty-four months from the date of purchase, covering faulty workmanship or materials.

Operation

Setting the temperature: Use the thermostat dial (1-6) to set the desired coldness, with intermediate positions usually being most suitable. The refrigerator and freezer compartments are regulated by a single thermostat. Adjust lower settings if the refrigerator is not defrosting correctly. The freezer compartment is suitable for storing commercially frozen food and freezing fresh foods.

Freezing fresh food: Freeze up to 3 kg in 24 hours, placing food in the upper drawer. Remove drawers for large quantities.

Thawing: Thaw food in the refrigerator. Small pieces of meat can be cooked while frozen. Vegetables in boiling water. Ready-cooked dishes in the oven. Microwave ovens are also suitable.

Making ice cubes: Fill provided trays 3/4 full and place in a freezer drawer. Twist tray to release cubes.

Troubleshooting and error codes

Issue	Troubleshooting Steps
The appliance does not work	Check that: There is power at the socket. Ensure that there is not a power cut by checking the household lights. The fuse has not blown. The air circulation passages are not covered. The thermostat dial is in the correct position.
Vibration or abnormal noises...	You may hear faint gurgling or bubbling sounds when the refrigerant is pumped through the coils of tubing at the rear, to the cooling plate/evaporator. When the compressor is on, the refrigerant is being pumped round, and you will hear a whirring or pulsating noise from the compressor. A thermostat controls the compressor, and you will hear a faint "click" when the thermostat cuts in and out.
Traces of water on the bottom of the fridge compartment...	The defrosting water discharge hole is not obstructed.
The light does not come on...	The bulb is fitted correctly. Replace the bulb if it has blown.
Fridge does not defrost...	The thermostat setting is not too high (see page 9).
Other points to check...	Have you turned the thermostat to the correct setting? Have doors been left open causing the temperature to rise? Sometimes the freezer door will be difficult to open shortly after you have closed it. Don't worry this is due to pressure difference which will quickly equalise and allow the door to open normally.
