2-1) Introduction of main function
●●
A newly Developed SAMSUNG bottom mount freezer in 2009 has the following
characteristics.
Surround Multi Flow
●●
Uniform cooling for each shelf and even in corner in fresh
food compartment by centerpositioned fan and duct with
multiple flow effluences

ASSEMBLY & DISASSEMBLY
3-1) PRECAUTION
• Unplug the refrigerator before cleaning and making repairs.
• 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.
