2. FEATURES & TECHNICAL EXPLANATION
2-1. FEATURES
Direct Drive System
The advanced Brushless DC motor directly drives the drum without belt and pulley.
Water Circulation
The detergent water from the drum is sprayed directly over the load ;
this enables the clothes to get soaked more quickly during the 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 Buttons 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.
Safety device (Aqua lock)
Aqua lock System is designed for detecting water leakage during operation to prevent
water from spilling on the floor.
Steam Washing and Refresh
Steam Washing features upgraded washing performance with low energy consumption.
Refresh cycle reduces wrinkles from dry clothes.

6
2-2. DETERMINE WASHING TIME BY FUZZY LOGIC
To get the best washing performance optimal time is determined by sensing the water
temperature, selected washing temperature and laundry amount.
2-3. WATER LEVEL CONTROL
This model adopts a pressure sensor which can sense the water level in the tub.
Water supply is stopped when the water level reach the preset level, then washing program proceeds.
Spinning does not proceed until the water in the tub reduces to a certain level.

4. 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 for humidity or any foreign objects under the feet.
Clean the floor, there should be no 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.
1
Open the box and check appliance condition.

Base Packing
Washer
Spanner
1. Remove the cardboard box and styrofoam packing.
2. Lift the washing machine and remove the base packing.
3. Remove the tape securing the power supply cord and
drain hose.
4. Remove the inlet hose from the drum.
Keep the spanner provided for future use.

9
Use spanner to remove transit bolts.
3
Check the distance between the appliance and the wall.
4
The tap connection and hose connection must be parallel.
5
Transit bolts
More than 2cm If the distance is less than 2cm,
the water supply hose will be
kinked or folded.
Unscrew
1. Unscrew the adapter ring plate and the 4 adapter retaining screws.
2. Push the adapter onto the end of the tap so that the rubber seal forms
a watertight connection. Tighten the adapter ring plate and the 4
screws.
3. Push the water supply hose vertically upwards so that the rubber
packing within in the hose can adhere completely to the tap and then
tighten it by screwing it to the right.
• Water supply pressure must be between 100 kPa and 1000 kPa (1.0 ~ 10.0 kgf / cm
2
)
• Do not strip or crossthread when connecting Inlet hose to the valve.
• If the water supply pressure is more than 1000 kPa, a decompression device should be installed.
• Periodically check the condition of the hose and replace the hose if necessary.
Type-A : Connecting Screw-type hose to tap with thread
• Screw the hose connector onto water supply tap.
■Connecting water supply hose
Step1 : Check rubber seal inlet hose
Step2 : Connect hose to water tap
• Two rubber seals are supplied with the water inlet hoses.
They are used for preventing water leaks. Make sure the connection to
taps are sufficiently tight.

Type-B : Connecting Screw-type hose to tap without thread
1. Unscrew the 3 bolts with the spanner supplied.
2. Take out the 3 bolts along with the rubber bungs by slightly
twisting the bung.
3. Close the holes with the caps supplied.
Keep the transit bolts for future use.

1. Unscrew the adapter ring plate and the 4 adapter retaining
screws.
2. Remove the guide plate if the tap is too large to fit the
adapter.
3. Push the adapter onto the end of the tap so that the rubber
seal forms a watertight connection.
Tighten the adapter ring plate and the 4 screws.
4. Pull the connector latch plate down, push the inlet hose onto
the adapter, and release the connector latch plate.
Make sure the adapter locks into place.
After completing connection, if water leaks from the hose, repeat the same steps.
Use the most conventional type of faucet for water supply. In case the faucet is square or too big, remove the
spacing ring before inserting the faucet into the adaptor.

Type-C : Connecting one touch type hose to tap without thread
Step3: Connect hose to washer
• Make sure that there are no kinks in the hose and that they are not
crushed.
When your washer has two valves.
• The Inlet hose With the red connector is for the hot water tap.
• If the washer has two valves, energy is saved by using the hot valve.
After connecting inlet hose to water tap, turn on the
water taps to flush out foreign substances (dirt, sand or
sawdust) in the water lines. Let water drain into a
bucket, and check the water temperature.

11
Connect Drain Hose.
6
Connect power plug.
7
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.

Step 1
If washing machine legs are loose or not Screwed in, then tighten with the spanner wrench.
Using the level, level the washing machine from front to back and side to side.
Step 2
Use the spanner wrench to adjust Legs until level and try the Diagonal test.
Step 3
Perform a Rinse and Spin with some clothing in the machine.
To do this, put 2~3kg of clothing in the unit, turn on the unit, Select the Rinse+Spin
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. (Repeat step 2)
Step 4
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.
