2. PRODUCT SPECIFICATIONS
The SAMSUNG bottom mount freezer in 2009 has the following characteristics.
2-1) Introduction of Main Function
7
Surround Multi Flow
Uniform cooling for each shelf by a center positioned fan and duct with multiple flow effluences.
Twin Cooling System
The refrigerator and the freezer have two evaporators. Given this independent system, the freezer and the refrigerator are cooled individually as required and are, therefore, more efficient. Food odor from the refrigerator does not affect food in the freezer due to separate air flow circulation.
Moving Tray
The Deli Drawer can be moved side to side for customer improved customer satisfaction.
Digital Display & Temperature Control
Digital Display & Temperature Control look and feel neat & clear design.
Easy Handle System(RF197AC,RF217AC)
The freezer door is more user-friendly and convenient.

3. DISASSEMBLY AND REASSEMBLY
• Unplug the refrigerator before cleaning and making repairs.
• Do not dissemble or repair the refrigerator by yourself.
- It may cause risk of causing a fire, malfunction and/or personal injury.
• Remove any foreign matter or dust from the power plug pins.
- Otherwise there is a risk of fire.
• Do not use a cord that shows cracks or abrasion damage along its length or at either end.
• Do not plug several appliances into the same multiple power board. The refrigerator should always be plugged into its own individual electrical which has a voltage rating that matched the rating plate.
- This provides the best performance and also prevents overloading house wiring circuits, which could cause a fire hazard from overheated wires.
• Do not install the refrigerator in a damp place or place where it may come in contact with water.
- Deteriorated insulation of electrical parts may cause an electric shock or fire.
• The refrigerator must be grounded.
- You must ground the refrigerator to prevent any power leakages or electric shocks caused by current leakage from the refrigerator.
• Do not put bottles or glass containers in the freezer.
- When the contents freeze, the glass may break and cause personal injury.
• Do not store volatile or flammable substances in the refrigerator.
- The storage of benzene, thinner, alcohol, ether, LP gas and other such products may cause explosions.
