2. FEATURES & TECHNICAL EXPLANATION
2-1. FEATURES
Anti Crease function
With the alternate rotation of the drum, creasing in the laundry is minimized.
More economical by Fuzzy Logic System
FUZZY Logic System detects the amount of load and water temperature, and then determines the optimum water level and washing time to minimize energy and water consumption.
Child-Lock
The Child-Lock system has been developed to prevent children from pressing any button (except Power button) to change the programme during operation.
Low noise speed control system
By sensing the amount of load and balance, this system automatically distributes load evenly to minimize the spinning noise level.
Direct Drive System
The advanced Brushless DC motor rotates the drum directly without a belt and a pulley.
Built-in heater
Internal heater automatically heats the water to the best temperature on selected cycles.

2-2. DETERMINE WASHING TIME BY FUZZY LOGIC
To get the best washing performance optimal time is determined by sensing of water temperature, selected washing temperature and laundry amount.

2-3. WATER LEVEL CONTROL
This model uses a pressure sensor to determine the water level in the tub.
When the preset water level reached, water supply is stopped and the program proceeds. 
W ater needs to be below a preset level before spining will proceed.

4. INSTALLATION
INSTALLATION
The appliance should be installed as follows.
1Check the conditions of installation area.
1. Check level ground.
horizontal
On raised foundations or upper level homes, the vibrations can be caused by the type of flooring. It may be necessary to move the machine to a different area in the home or have the floor reinforced to properly support the operation of the unit.
2. Check humidity or any foreign objects under the feet.
Clean the floor, and there should not be any foreign objects under the feet.
If the unit has foreign objects underneath the feet, this will prevent the unit from being leveled properly and will cause vibrations and slipping .
Remove any foreign objects , if any from underneath the machine and level unit properly. See below for examples of foreign objects.

6 Connect Drain Hose.
If the drain hose is not installed properly, the unit will not drain properly. This allows water to back flow into the unit which can cause odors. Refer to Owner Manual for proper drain hose installation.
The odor could also be coming from the home’s drain to which the drain hose is attached.

In this type of drain hose installation, the odor could be coming from the standpipe. This odor can come up the drain hose and into the unit.
Pour a cup or two of bleach or vinegar down the home drain and let it sit for 24 hours before running another cycle.
This will help eliminate odor from the home drain.
If a cycle is started too soon after doing this, it will not help the issue.
7 Connect power plug.
Connect the power plug to the wall outlet.
Avoid connecting several electric devices, it may be the cause of a fire.

8 Check the horizontality with a level (Gage).
1 Step
If washing machine legs are loose or not screwed, then screw up with the spanner wrench. Using the level, level the washing machine from front to back and side to side.

2Step
Using the spanner wrench to adjust leg for horizontality and try for Diagonal test .
Diagonal test |
How to perform a diagonal test: |
Place your right hand on the back, right corner and your left hand on the front, left corner of the unit, then attempt to rock the unit from corner to corner. Then, move your right hand to the front, right side and your left hand to the back, left corner and attempt to rock the unit from corner to corner.
If the unit is level, it will not rock. However, if the unit is not level, it will rock. If the unit rocks, it will be necessary to adjust the leveling feet of the unit. Adjust the foot under the hand that is on the front of the machine.
