1. PRECAUTIONS(SAFETY WARNINGS)
Pull the power plug out before
attempting to exchange the
interior lamp of the refrigerator.
●
This will prevent danger of electric
shock.
Warning & Caution
Unplug
Use only rated components for
replacement.
●
Check the correct model, rated
voltage, rated current, operating
temperature.
Before repair, make sure that the
wires such as harness are bundled
tightly.
●
Bundle wires tightly so that they
are not detached easily and get wet.
Check if there is any trace indicating
the permeation of water.
●
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 as before disassembly.
When repairing, completely remove
dust and foreign substances from
housing, wiring, joint etc..
●
It may prevents fire due to tracking
or short.
Rated
components
When installing, servicing, or
cleaning behind the refrigerator, be
sure to pull the unit straight out and
push back in straight after finishing.
Also, make sure your floor supports
the full-load refrigerator. Otherwise, it
may cause floor damage.
CAUTION

●
Please let users know following warnings & cautions in detail.

2. PRODUCT SPECIFICATIONS
NOTE
Key features of your new refrigerator
Your Samsung Side-By-Side Refrigerator comes equipped with
many space-saving, innovative storage and energy-efficient
features.
• Twin Cooling PlusTM
Twin CoolingTM‚ system uses two evaporators to independently
control temperature of the refrigerator and freezer compartments
maintaining proper humidity levels and preventing odor transfers
between compartments.
• Multi Airflow
Provides even cooling throughout the refrigerator to maintain
optimal temperatures to keep food fresh.
• LED Tower Lighting
See everything in a new light with LED tower lighting.
• CoolSelect ZoneTM (Optional)
This function control te Coolselect Zone temperature after
satisfying inner temperature of the Fridge compartment. But if the
temperature of the Fridge compartment is under -4°C, the
operation of the Fridge compartment will be off even though the
Coolselect Zone temperature is not satisffied.
• Clear View Icemaker
The Icemaker is located in the freezer door, this ensures that all
the shelf space can be fully utilized. Ice cubes are quickly
produced and the clear ice bucket lets you easily see the amount
of ice cubes produced.
• Premium Design Ice & Water Dispenser
Quick and easy access to filtered water and cubed/crushed ice at
your fingertips with the external dispenser.
This operation instruction covers various models. The characteristics of your appliance
may differ slightly from those described in this manual.
