WarnIng WHILe ServIcIng • Check if the power plug and outlet are damaged, flattened, cut or otherwise degraded. √ If faulty, replace it immediately. Failing to do so may result in electric shock or fire. • Completely remove any dust or foreign material from the housing, wiring and connection parts. √ This will prevent a risk of fire due to tracking and shorts in advance. • When connecting wires, make sure to connect them using the relevant connectors and check that they are completely connected. √ If tape is used instead of the connectors, it may cause fire due to tracking. • Make sure to discharge the PBA power terminals before starting the service. √ Failing to do so may result in a high voltage electric shock. • When replacing the heater, make sure to fasten the nut after ensuring that it is inserted into the bracket-heater. √ If not inserted into the bracket-heater, it touches the drum and causes noise and electric leakage. WarnIng after ServIcIng • Check the wiring. √ Ensure that no wire touches a rotating part or a sharpened part of the electrical harness. • Check for any water leakage. √ Perform a test run for the washing machine using the standard course and check whether there is any water leakage through the floor section or the pipes. • Do not allow consumers to repair or service any part of the washing machine themselves. √ This may result in personal injury and shorten the product lifetime.
Page 5
cautIon Before ServIcIng • Do not sprinkle water onto the washing machine directly when cleaning it. √ This may result in electric shock or fire, and may shorten the product lifetime. • Do not place any containers with water on the washing machine. √ If the water is spilled, it may result in electric shock or fire. This will also shorten the product lifetime. • Do not install the washing machine in a location exposed to snow or rain. √ This may result in electric shock or fire, and shorten the product lifetime. • Do not press a control button using a sharp tool or object. √ This may result in electric shock or damage to the product. cautIon WHILe ServIcIng • When wiring a harness, make sure to seal it completely so no liquid can enter. √ Make sure that they do not break when force is exerted. • Check if there is any residue that shows that liquid entered the electric parts or harnesses. √ If any liquid has entered into a part, replace it or completely remove any remaining moisture from it. • If you need to place the washing machine on its back for servicing purposes, place a support(s) on the floor and lay it down carefully so its side is on the floor. √ Do not lay it down on its front. This may result in the inside tub damaging parts. Safety Instructions _ 3...
Page 6
cautIon after ServIcIng • Check the assembled status of the parts. √ They must be the same as before servicing. • Check the insulation resistance. √ Disconnect the power cord from the power outlet and measure the insulation resistance between the power plug and the grounding wire of the washing machine. The value must be greater than 10MΩ when measured with a 500V DC Megger. • Check whether the washing machine is level in relationship with the floor. Check whether it is installed firmly on the floor. √ Vibrations can shorten the lifetime of the product. 4 _ Safety Instructions...
2. Features and speciFications 2-1. Features ■ common Features Features Description Big Door • This is the maximum capacity to be implemented at the standard 55 cm depth. - The benefits for customers have been greatly increased due to the efficient use of limited space. - Usability has been improved due to the easier loading and removing of the laundry. • The size of the loading entry has increased: 300 mm → 308 mm (Wide) - A lot more washing can be conveniently added and removed. 308 mm Diamond Drum • The washing performance has increased but potential damage to the washing has been minimized. (The size of the holes on the diamond drum has been reduced for minimizing damage to the washing.) - The embossed wall of the drum serves as a washboard, dramatically increasing the washing performance compared with existing drum washing machines, which use the power of the difference in elevation only. - The size of holes has been reduced drastically, maintaining the optimal wash performance (Washing Cost 1.0) while saving on water and electricity required for washing. - The structure of the holes on the diamond drum has been changed minimizing potential damage to the washing since it is difficult for strands to enter the holes.

■ common Features Features Description Bubble Wash • Bubble Cushion - Eco Bubble technology activates the detergent much earlier and faster in the wash cycle by use of a Bubble Generator, rapidly mixing a small amount of water with air and detergent (works with powder, tabs or liquid detergents). This creates a foam cushion in the drum ahead of introducing the main water intake. • Super energy saving - the detergent infused bubbles penetrate the fabrics much faster and efficiently than for a conventional wash system, delivering a cleaner wash performance especially for colder temperature cycles. The lower the water temperature of the cycle, the greater the impact of using Eco Bubble versus conventional systems, this allowing more use of colder wash cycles and helping to save energy beyond the A+++ energy rating of this appliance. • No detergent remainning - the detergent disslove completely in a very short time while wash begin by bubble wash technology,so don’t afraid of detergent remainnin. 6 _ Features and Specifications...

(40-minute cycle) • Washing one or two shirts in 30 minutes - If a piece of clothes is not completely dry when it is humid, the machine can dry it within 30 minutes • Preventing bio-film caused by humidity from occurring - You do not need to worry about the humidity inside the drum. - The drum is dried regularly, preventing bio-film. Water Safety System • The Water Safety System has invented for perfect leakage protection. The double safety valve connects directly to the water faucet. In the event of a leakage, the built-in sensor immediately detects the leak within a few short seconds, automatically turning off both the water supply and the washing machine.
