4. FEATURES & TECHNICAL EXPLANATION
4-1 New Technology Introduction
• During the high temp. Rinse course, water
temperature in an dishwasher reaches 80°C,
considerably higher than the average rinse
temperature in conventional
dishwashers(65°C). This is how Rinse 80°C
can eliminate some bacteria such as
salmonella.
4-1-1. High Temperature Rinsing (Extra Hot function)
• Dual intensity course has different water
pressure levels between lower rack and upper
rack.Upper rack has medium pressure and
lower rack has strong pressure respectively.
So, During washing medium soil in upper rack,
you can wash hard soil in the lower rack.In this
course, you can’t change the spray intensity.
4-1-2. Dual intensity
• Newly introduced Slim Direct Inverter motor is
inverter-controlled. Speed is controlled based
on program selection. It also offers high energy
efficiency to minimize energy loss.
4-1-3. Slim Direct Inverter Motor
Moist
Air
Dry
Air
Mixed
Air
• This is one of the best performance solutions
for drying dishes because it minimizes venting
humid air to the outside of the dishwasher. In
addition, this system ensures better drying
results compared to the condensing drying
system.
