SAFETY

Disposal of Old Appliance
DANGER! Risk of child entrapment.
Child entrapment and suffocation are not problems of the past. Junked or abandoned refrigerators are still dangerous ­ even if they will sit for “just a few days.” If you are getting rid of your old refrigerator, please follow these instructions to help prevent accidents.
Before you discard old appliances:
· Take off the doors. · Leave the shelves in place so that children
may not easily climb inside. · Cut off the power cable from the discarded
appliance. Discard separately from the appliance. · Be sure to follow your local requirements for disposal of appliances. Contact the trash collection agency in your area for additional information.
Disposal of this Appliance
This appliance contains flammable gases within the refrigeration circuit and insulation foam.
Contact the municipality or disposal company in your area for information on approved recycling or disposal.
Disposal of Batteries
A rechargeable battery is installed in the appliance.
The battery must be removed when you wish to dispose of the appliance and sent for separate waste treatment for batteries.
Contact a disposal company in your area for information on approved disposal of batteries.
Do not damage or short-circuit the battery.

Disposal of Carton
The packaging is designed to protect the appliance and individual components during transport and is made of recyclable materials.
WARNING! Keep packaging materials away from children. Polythene sheets and bags can cause suffocation!
If possible, please recycle packaging material at a recycling facility.
R290 Refrigerant
WARNING! The refrigerant R290 contained within the appliance is environmentally friendly, but flammable. Leaking refrigerant can ignite.
To prevent possible ignition, follow the warnings below:
· Keep ventilation openings, in the appliance enclosure or in the built-in structure, clear of obstruction.
· To ensure proper ventilation, the clearance between the appliance top and the ceiling must be at least 12 inches.
· Do not use mechanical devices or other means to accelerate the defrosting process, other than those recommended by the manufacturer.
· Do not damage the refrigerant circuit.
· Component parts and power cords shall be replaced with like components performed by factory authorized service personnel only.
· Do not use electrical appliances inside the food storage compartments of the appliance, unless they are of the type recommended by the manufacturer.

SAFETY

Important Safety Information
· If the appliance is damaged on delivery, contact the supplier immediately before connecting it to the power source.
· To guarantee safe operation, ensure that the appliance is set up and connected as described in this manual.
· Disconnect the appliance from the power source if a fault occurs. Pull out the plug, turn off or disable the power source.
· When disconnecting the appliance, always pull it out by the plug; never pull on the cable.
· Any repairs and work on the appliance should only be performed by the customer service department. Unauthorized work may be dangerous to the user. The power source cable should only be changed or replaced by the customer service department.
· Do not store explosives or sprays using combustible propellants such as butane, propane, pentane, etc. in the appliance. Electrical components might cause leaking gas to ignite. You can identify such sprays by the printed contents or a flame symbol.
· To prevent possible injury due to an electrical shock, be sure to disconnect the power cord or turn off the circuit breaker before cleaning the appliance.
· To avoid injury or damage to the appliance, do not use steam cleaning equipment to clean the appliance.
· Do not operate the appliance in the presence of explosive fumes.
· In the event of a power outage, open the door as infrequently as possible.
· To protect the appliance from possible damage, allow it to stand 1/2 to 1 hour in place before turning on the electricity. This allows the refrigerant and system lubrication to reach equilibrium.

TROUBLESHOOTING

Troubleshooting
Your appliance is designed and manufactured for a long life and reliable operation. If a problem occurs during operation, check whether it is due to an operating error. Please note that even during the warranty period, you may be responsible for certain repair costs.

Problem Appliance does not work, display is off.
Motor seems to run too long. The temperature is not cold enough.

Possible cause and remedy
– Is the appliance turned on? – Is the power cord properly inserted in the outlet? – Is the circuit breaker or fuse in working order?
– Is the ambient temperature too hot? See Safety Regulations. – Has the appliance been opened too often or left open too long?
– Is the temperature setting correct? See Setting the Temperature. – Does a separately installed thermometer show the correct reading? – Is the ventilation system working properly? – Is the appliance set up too close to a heat source?

Temperature alarm test – See ,,Adjusting the alarm parameters” and ,,Alarm test” does not work as required.
