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:
- Remove 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.

The Right Environment for Your Wines
A grapevine is an extremely sensitive plant. From the time it is planted until its maturing period and the time the grapes are harvested and the wine is made, it is dependent on three factors: light, air humidity and ambient temperature.
This sensitivity continues even after the wine is bottled.
To allow the flavor of the wine to fully develop or to preserve the excellent aroma, the wine has to be stored at optimal conditions. Your wine cooler offers the best conditions for this.
Wines only develop their full flavor and aroma when they are at the right temperature for drinking.
In your wine cooler, wines can be brought slowly and evenly to the ideal drinking temperature.
Red wines and white wines can be stored at the same time at the optimal drinking temperature in two separately adjustable temperature zones.
