1. INTRODUCTION

A newly developed SAMSUNG side by side refrigerator in 2002 has the following

characteristics.

1) T win 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.

2) 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.

3) Xtra Space

TM

Vertical room next to the ice maker in the freezer
provides space for pizza etc.

4) Door Alarm

Beep sound reminds you the door is open.

5) Xtra Fresh

TM

Optimized humidity control keeps vegetables & fruits
fresh.

6) Deodorizer

Reusable deodorizer keeps the refrigerator air
fresh and odor free.

7) CoolSelect ZoneTMDrawer (Optional)

User can select Quick Cool, and Select for quickly
soft freeze, chill, and cool. Select Soft freeze,Chill or
Cool to control the temperature of the drawer.

2. INSTALLATION

1) T o protect refrigerator in movement

Use padded hand truck as shown. If entrance width is
less than 1m, remove doors prior to installation and
reattach doors according to procedure below.

2) Remove all protective tape and pad in refrigerators.

Connect water lines and power cord. 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 low

You can store food in the refrigerator. After starting the
refrigerator, it takes a few hours to reach the appropriate
temperature.

Removing Doors

Open the freezer and refrigerator doors, and
then take off the front leg cover assembly by
turning the three screws counter-clockwise.
Remove the screw from clamp disconnect, the
water tube by pressing the coupler, and pulling
the water tube away .

With the door closed, remove the upper hinge
cover using a screwdriver, and then disconnect
the wires. Remove hinge screws and ground
screw counter-clockwise, and take off the upper
hinge. Take care removing the door to ensure that
it does not fall on you.

Remove the door from the lower hinge by
carefully lifting the door so as not to damage the
water tube. Remove the lower hinge from the
lower hinge bracket by lifting the lower hinge.

Attaching Doors

Insert the lower hinge in the bracket lower
hinge. Attach the freezer door by inserting the
hose in the lower side of the door into the hole in
the lower hinge and pulling the hose down.

Insert the upper hinge shaft into the hole. After
leveling between the upper hinge hole and the
hole of the cabinet. Reattach hinge screws and
screw in the clockwise direction. Connect the
wires. Put the front part of the upper hinge cover
on the front part of the upper hinge and reattach
from the front part of the upper hinge cover first.

8. Operation Function

When the system power is initally engaged, the default set temperature are -20 for the freezer and 3 for the set
refrigerator, respectively. The numbers shown on the digital display panel stand for the actual compartments
temperatures. When the compartment temperatures go down, so do the numbers on the display panel, and finally they
reach the set temperatures. Once the system is stabilized, the display temperatures are the set temperature.

1) Freezer Temperature Control.
To select a set temperature, press the Freezer Temp. button. The display shows the set temperature from -14

to

-25

in sequence.

2) Refrigerator Temperature Control.
To select a set temperature, press the Fridge Temp. button. The display shown the set temperature from 1

to

7

in sequence.

note) Because of the temperature sensor sensivity , the refrigerator can be under and/or over cooled when

the air flow is blocked by stored foods. (Temperature range of the sensor :

-9∼30

)

In the event of a power failure, if the freezer temperature is maintained lower than

5

, the last

selected set temperature and functions memorized in EEPROM will be restored when the power is on.

Note) Initially the light of moisture control button is on. If the moisture in the dispenser or Beverage Station

TM

is

found, press this button. So the light will be on, and eliminate the moisture.

8-4) Child Lock Function

● Select the Power Freeze or Power Cool buttons separately .

● These buttons are toggled ON and OFF and the indicators as well.

● Although you select Power Freeze or Power Cool, the set temperatures in the freezer and refrigerator are not

changed.

● The set temperatures for the compartments can be changed while these functions are in use.

1) Power Freeze function
1-1) When you press the Power Freeze button, the LED indicator lights right away, but there is 10 seconds lag time

to an actual

operation. When this button is pressed again, the Power Freeze function stops and the indicator is off

immediately .

1-2) If you select Power Freeze, both the compressor and the freezer fan run for 10 hours continuously .

1-3) During Power Freeze, the freezer retains the current settings.
1-4) When Power Freeze expires, the indicator goes off and the freezer set temperature will be restored.

2) Power Cool function

2-1) Power Cool operation and the indicator work exactly same as the Power Freeze function.

2-2) When Power Cool is selected, COMP and R-FAN operate continuosly until the refrigerator reaches -4

. This

function will be terminated after 2

½ hr running.

3) When you select Power Freeze and Power Cool together

Each function works at the same time. The COMP and F-FAN run continuously and the R-FAN runs until -4

in the refrigerator.

4) Initial Power-On

4-1) The freezer and the refrigerator temperatures are higher than -10 and 10 espectively if, respectively. If Power

Freeze is selected, the R-FAN will be of f. If Power Cool is selected, the F-FAN will be off.

4-2) When both functions are selected, there is no benefit of fast cooling for each compartment.

● When the child lock button is pressed for 3 seconds, the child lock indicator is on with an audible tone.

-When it is locked, no function commands except the Ice type button will be accepted.

-This function will prevent accidental setting that may be caused by children or pets.

-To unlock the setting functions, press this button for 3 seconds again.

note) When the Power Freeze is selected, it enables maximum ice maker output. The ice making interval is

reduced from 90 mins to 55 mins (55 mins after the water delivery, if the ice temperature is maintained
lower than -7

, the ice tray will be twisted). When the ice bucket is full before 10 hours of operation,

Power Freeze is automatically terminated.
