1. SAFETY WARNINGS
● Pull the power plug out already 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 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 store the foods unstable or bottles in the freezing room.
● Do not repair the refrigerator by user himself.
● Do not store another materials except the foods.
→ Drugs or scientific materials : difficult to keep a precise temperature.
→ The inflammables(alcohol, benzene, ether, LP gas, butane gas etc.):
have a risk of explosion.

● Check the correct model, rated
voltage, rated current, operating
temperature and so on.
On repair, make sure that the
wires such as harness are
bundled tightly.
● Bundle tightly wires in order not to be
detached by the external force and then not
to be wetted.
Check if there is any trace
indicating the permeation

● If there is that kind of trace, change
the related components or do the
necessary treatment
such as taping
using the
insulating tape.
After repair, check the
assembled state of components.
● It must be in the same assembled state
when compared with the state before
disassembly.
On repair, remove completely dust
or other things of housing parts,
harness parts, and check parts.
● Cleaning may prevent the possible fire by
tracking or short.

2. INSTRUCTION
Our side by side refrigerator has the following characteristics.
Twin Cooling System
• The refrigerator and the freezer have two
evapora
tors. 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 of air flow circulation.
Multi-Flow System
• Cool air circulates through multiple vents on
every
shelf level. This provides even distribution of
cooling inside cabinets to keep your food fresh
longer.
Door Alarm
• A beeper reminds you if the door is left open.
High humidity for fresher food
• You can keep food, fruit and vegetables fresh for
longer because your refrigerator supplies highly
humidified cold air. This can be up to four or five
times more effective than a normal refrigerator.
Energy-saving fridge/freezer
• Power consumption is kept to a minimum by
distributing cool air separately to the refrigerator
and freezer.
Faster cooling times
• The power freeze function allow you to freeze food
more quickly.
Abundant supply of ice and cold water
• The ice and water dispenser provides ice and cold
water at any time.
Beverage Station (optional)
• You do not have to open the main door to access
frequently used food in the extra
refrigerating compartment. This saves time
and money.
Deodorizer (optional)
• Reusable deodorizer keeps the refrigerator air
fresh and odor free.
NOTE
This operation instruction covers various models.
The characteristics of your appliance may differ slightly from those described in this
manual.

3. INSTALLATION

1) To protect refrigerator in movement
Use padded hand truck as shown. If entrance width is
less than 30 , remove doors prior to installation and
reattach doors according to procedure below.
2) Remove all protective tape and pad in refrigerators.
Please adjust the clearance between the doors.
3) Set the temperature control to the temperature and
wait for an hour.
The refrigerator should get slightly chilled and the motor
runs smoothly.
4) Once the refrigerator temperature is sufficiently cool
You can store food in the refrigerator. After starting the
refrigerator, it takes a few hours to reach the appropriate
temperature.
Disassemble the refrigerator
1) With the door closed, disassemble screw() by
using (+) screw driver and then disassemble the
upper hinge cover().
2) Disassemble bolts () and screws () to the
counter-clockwise by using a tool, and take off the
upper hinge () along the arrow (). Take care
when you disassemble the door to ensure that it does
not fall on you.
3) Disassemble the door from the lower hinge () by
lifting the door ().
4) Disassemble the lower hinge () from the bracket
lower hinge () by lifting the lower hinge () in the
direction of the arrow.
Assemble the refrigerator
1) Insert the lower hinge () in the bracket lower
hinge ().
2) Assemble the door () in the lower hinge ().
3) Insert the upper hinge shaft () into the hole (). After
leveling between the upper hinge hole () and the
hole of the refrigerator (), assemble bolts ()
and screws () to the clockwise by using a tool.
4) Put the front part of the upper hinge cover () on the
front part of the upper hinge () and assemble,
starting with the front part of the upper hinge
cover. Assemble the screw to the clock wise by
using a tool.
