2. PRODUCT SPECIFICATIONS

●●

A newly developed SAMSUNG side by side refrigerator in 2006 has the following

characteristics.

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.

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.

Xtra Space

TM

●●

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

Door Alarm

●●

Beep sound reminds you the door is open.

Xtra Fresh

TM

●●

Optimized humidity control keeps vegetables & fruits fresh.
(RS263B/RS265L)

Deodorizer

●●

Reusable twin deodorizers keep the refrigerator air fresh and odor
free.

CoolSelect ZoneTMDrawer

3-1) Digital Panel

When the system power is initally engaged, the default set temperature are -4℉ for the freezer and 38℉ 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
8 ℉ in sequence.

2) Quick Ice Freezer Temperature Control
Interior Temperature of the freezer will be controlled with -14 degrees Fahrenheit until the ice bucket is filled up with
ice cubes. When the ice bucket is filled up with ice cubes, the freezer will run with original set temperature. Also,
whenever the ice bucket is released from being filled with ice cube, the freezer will repeat
to be controlled with -14 degrees Fahrenheit. But if you select "Ice Off, the freezer always will be controlled with
original set temperature.

3) Refrigerator Temperature Control.
To select a set temperature, press the Fridge Temp. button. The display shown the set temperature from 34℉ to
46℉ 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 : 15℉∼80℉)
In the event of a power failure, if the freezer temperature is maintained lower than 41℉, the last
selected set temperature and functions memorized in EEPROM will be restored when the power is on.

2) Preparation of Ice-maker
2-1) Connect the water line to the water supply valve of refrigerator to supply water. (See how to connect a water

supply line in the owner’s manual.)

2-2) Push the bucket back fully so that the guide-ice of ice maker should not touch the back of bucket. (If the back of

bucket is touched the guide-ice of ice maker, the ice maker will not make ice any more because of a ice full signal.)

2-3) It takes 6 hours to harvest a first ice, and throw away 2-3 times of these ice to make sure the supplied water clean.

1) Initial Operation function
1-1) Whenever the power is on, the control board checks the ice tray leveling with the leveling switch within 2 seconds.
1-2) If the leveling switch is not off position, the geared motor will turn to the initial position to make the ice tray leveled.
1-3) When the ice tray is leveled, it will remain this position for 2 hours (1 cycle time for ice production).
1-4) After 2 hours, the sensor located under the ice tray will measure the tray temperature. If the temperature is

maintained lower than 1℉ for 5 minutes, and the ice full switch is off position, the ice tray twisting process will
begin.

Push the bucket back fully so that the
lever should not be pushed up.

3. OPERATING INSTRUCTIONS & INSTALLATION

2) Water Supply function
2-1) When the ice tray is levelled again after ejecting ice, the water solenoid value will be controlled to supply water by

time check basis. (See the “Time to supply water” Table)

3) Ice production

3-1) After 60 minutes pass from the water supply, the control board will check the temperature.
3-2) If the sensor reads the temperature lower than 1℉ for more than 5 minutes, than the ice production process is

completed.

4) Test function

● In order to operate a test function, press the knob (Test Switch) for 1.5 second.

● This function can be used to check a proper working, to clean the ice tray, and to adjust the water level in the ice tray.

4-1) This function only works when the ice tray is leveled and the ice full signal is cleared.
4-2) When the water line is connected, each process such as a water supply, ejection, and leveling, can be investigated

by this button.

5) Ice off function

5-1) When the Ice off option is selected by Ice Type button, the ice making process will cease.
5-2) When the ice making process ceases, the final state will be the ice tray with supplied water.
5-3) When Cubed or Crushed option is selected again, the control board will check an accumulated time period. After

making it 60 minutes and when the ice tray temperature is acceptable, ice ejection process will begin.

6) Functions when the freezer door is open

● When the freeze door is open, all ice maker related processes will cease in order to minimize noise and to prevent ice

from dispensing.
6-1) The ice tray stops moving regardless of the position.
6-2) The water supply process remains working as usual.
6-3) If the ice tray is in the middle of ice ejecting process, close the freezer for 30 seconds and check if the tray is

leveled. If it is not leveled, it must be out of order.

1) A defrost is determined based on the accumulated compressor on-time.

2) When the power is engaged for the first time, the defrost cycle for the freezer and the refrigerator will begin after 4
hours of the accumulated compressor on-time.

3) A defrost interval depends on the ambient temperature, the number of door openings, and the door open time.

4) A minimum interval is 6 hours and a maximum is 8 hours for the refrigerator, and 12 hours and 16 hours for the
freezer, respectively.

5) The defrost heater on-time is determined by the defrost sensors as follow :
