- FEATURES & TECHNICAL EXPLANATION
2-1. FEATURES
Direct Drive System
The advanced Brushless DC motor directly drives the drum without belt and pulley.
Water Circulation
Spray detergent solution and water over the load over continu.
Clothes are soaked more quickly and thoroughly during wash cycle.
The detergent suds can be removed more easily by the water shower during rinse cycle.
The water circulation system uses both water and detergent more efficiently.
Built-in Heater
Internal heater automatically heats the water to the best temperature on selected cycles.
Child Lock
The Child lock prevents children from pressing any button to change the settings during
operation.
More economical by Intelligent Wash System
Intelligent Wash 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.
Low noise speed control system
By sensing the amount of load and balance, it evenly distributes load to minimize the
spinning noise level.
Automatic Wash Load Detection
Automatically detects the load and optimizes the washing time.

- INSTALLATION
INSTALLATION The appliance should be installed as follows.
Check the conditions of installation area.
1. Check level ground.
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.
7 Connect power plug.
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.
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.
2 Step Using the spanner wrench to adjust leg for horizontality and try for Diagonal test.
3 Step Perform a Rinse and Spin with some clothing in the machine. To do this, put 2~3kg of clothing in the unit, power on the unit, press the Rinse and Spin button, and then start. When the unit reaches the spin cycle, watch for vibrations. If the unit is vibrating, make small adjustments to the leg until they subside. (Try 2Step again)
4 Step Tighten the lock nut against the base of the machine to lock the position leg.
Lower the foot until there is no gap between floor and foot. And only use adjustment rubber when difference at the leg adjustment is more than 10mm.
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.
