1. PRECAUTIONS(SAFETY WARNINGS)
• Unplug the appliance before the changing orrepairing the 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 rmly the types of harness.
→ Make not to be separated when some power is imposed.
• Check the traces of water inltration at the electric parts.
→ If there is a trace of water inltration, exchange or tape the parts.
• Check the assemble status of parts aftertroubleshooting.
→ It must be in the same assembled state when compared with the state before disassembly.
• 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.
• Ground the refrigeratorproperly
→ 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 red.
→ If the plug or plug socket is damaged, repair or exchange it immediately.
• Do not allow consumers to repairthe appliance by themselves.
• Do not store othermaterials except the foods.
→ Drugs or scientic materials : difcult to keep precise temperature.
→ The inammables(alcohol, benzene, ether, LP gas, butane gas etc.): have risk of explosion.

PRECAUTIONS(SAFETY WARNINGS)
For proper installation, this refrigerator must be
placed on a level surface of hard material that is
the same height as the rest of the flooring.
This surface should be strong enough to support a
fully loaded refrigerator.
FLOORING
Protect the finish of the flooring. Cut a large
section of the cardboard carton and place
under the refrigeratorwhere you are working.
When moving, be sure to pull the unit straight
out and push back in straight.

Surround Multi Flow
• Uniform cooling for each shelf and even in corner in fresh food
compartment by centerpositioned fan and duct with multiple ow
efuences.
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 efcient.
Food odorfrom the refrigerator does not affect food in the freezer due to
separate air ow circulation.
Secure Auto Close DoorSystem
• Secure Auto Close DoorSystem
• Cool tight doors
• Energy saving
• Preventing sweat on fridge doors

• Unplug the refrigeratorbefore cleaning and making repairs.
• Remove any foreign matterordust from the powerplug pins.
- Otherwise there is a risk of re.
• Do not use a cord that shows cracks orabrasion damage along its length orat eitherend.
• Do not plug several appliances into the same multiple powerboard. The refrigeratorshould 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 re 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 re.
• The refrigeratormust 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 orglass containers in the freezer.
- When the contents freeze, the glass may break and cause personal injury.
• Do not store volatile or ammable substances in the refrigerator.
- The storage of benzene, thinner, alcohol, ether, LP gas and other such products may cause explosions.

- Waterwhitening phenomenon
All water provided to refrigerators ows through the core lter which is an alkaline water lter. In this process, the pressure
in the water that has owed out of the lter gets increased, and massive oxygen and nitrogen become saturated. When this
water ows out in the air, the pressure plummets and the oxygen and nitrogen get supersaturated so that they turn into
gas bubbles. The watercould look misty due to these oxygen bubbles. It is not because dust orchemicals, just a few seconds
later, it will be clean again.
