9 PRODUCT SPECIFICATIONS • A newly developed SAMSUNG bottom mount freezer in 2012 has the following characteristics. 2-1) Introduction of Main Function Surround Multi Flow • Provides uniform cooling for each shelf and every corner in the fresh food section. This is accomplished by using a center positioned fan and duct with multiple cooling flow openings. Twin Cooling System • The refrigerator and the freezer each have an evaporator. 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. Electronic control from outside of Pantry Cover(RF323TED***) • Adjustable temperature control ((around 41℉(5℃) : Deli / around 38℉(3℃) : Fresh / around 34℉(1℃) Chilled ) Temperature control from outside of the Pantry : user friendly design helps keep foods fresh for longer Two Lever Dispenser • Separate levers for ice and water. Secure Auto Close Door System • Doors close tightly. • Food on the doors stays cool. • Prevents moisture from forming on the outside of the doors. Easy Handle System • Ez-open Freezer Door • Ergonomic Door Design
