1. INTRODUCTION

●●

SAMSUNG side by side refrigerator 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

·V ertical 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

·Optimized humidity control keeps vegetables & fruits fresh.

6) Deodorizer

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

7) CoolSelect Zone

Drawer(RS2555, RS2577)

·User can select Quick Cool, Thaw and Select buttons

for quickly chill, thaw and cool items. Select Soft freeze,Chill, and 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 39〃, 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.

●●
