1. PRECAUTIONS(SAFETY WARNINGS)
● Pull the power plug out before for the change or repair of electric parts.
→ Be careful the electric shock.
● When exchanging the parts, use the correct parts.
→ Check the model name, rating voltage, rating current, running
temperature symbols.
● When troubleshooting, connect firmly the types of harness.
→ Make not to be separated when some power is imposed.
● Check the traces of water infiltration at the electric parts.
→ If there is a trace of water infiltration, exchange or tape the parts.
● Check the assemble status of parts after troubleshooting.
→ It should be done indiscriminately as before the repair.
● Check the use circumstance of refrigerator.
→ If the refrigerator is installed at the place that is damp or wet, or
status of installation is unstable, change the installation place.
● Do earth in case of need.
→ Particularly, Be sure to earth when there is a risk of an electric
leakage by humidity or wetness.
● Do not use multi plugs in a plug socket at the same time.
Check if the power cord and socket is damaged, pressed, squeezed,
or fired.
→ If the plug or plug socket is damaged, repair or exchange that
immediately.
● Do not repair the refrigerator by user himself.
● Do not store other materials except the foods.
→ Drugs or scientific materials : difficult to keep precise temperature.
→ The inflammables(alcohol, benzene, ether, LP gas, butane gas etc.):
have risk of explosion.

●●A newly Developed SAMSUNG bottom mount freezer in 2008 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
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.
Electronic control from outside of Pantry Cover
●●Adjustable temperature control (around 34 (1 )
Chilled / around 38 (3 ) : Fresh) Temperature control
from outside of the Pantry : user friendly design helps
keep foods fresh for longer
