Safety Instructions _ 1

WARNING

• Check if the power plug and outlet are damaged, ﬂ attened, cut or otherwise degraded. √ If faulty, replace it immediately.

Failing to do so may result in electric shock or ﬁ re.

• Completely remove any dust or foreign material from the housing, wiring and connection parts. √ This will prevent a risk of ﬁ re 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 ﬁ re 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.

WHILE SERVICING

WARNING

• 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 ﬂ oor 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.

• If it seems that grounding is needed due to water or moisture, make sure to run grounding wires. (Check the grounding of the power outlet, and additionally ground it to a metallic water pipe.)

√ Failing to do so may result in electric shock due to electric leakage.

[Running a grounding wire]

- Twist a grounding wire (copper wire) two or three times around the tap.

- If you connect the grounding wire to a copperplate, bury it 75 cm under the earth in a

place with a lot of moisture.

Do not connect the grounding wire to a gas pipe, plastic water pipe or telephone

wire. There is a risk of electric shock or explosion.

CAUTION

• Do not sprinkle water onto the washing machine directly when cleaning it. √ This may result in electric shock or ﬁ re, 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 ﬁ re. 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 ﬁ re, and shorten the product lifetime.

BEFORE SERVICING

• Do not press a control button using a sharp tool or object. √ This may result in electric shock or damage to the product.

CAUTION

• 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.

WHILE SERVICING

• If you need to place the washing machine on its back for servicing purposes, place a support(s) on the ﬂ oor and lay it down carefully so its side is on the ﬂ oor.

√ Do not lay it down on its front. This may result in the inside tub damaging parts.

Safety Instructions _ 3

CAUTION

• 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 ﬂ oor. Check whether it is installed ﬁ rmly on the ﬂ oor.

√ Vibrations can shorten the lifetime of the product.

2-1. FEATURES

■ COMMON FEATURES

Features Description Big Door • This is the maximum capacity to be implemented at the standard 55 cm depth.

- The beneﬁ ts for customers have been greatly increased due to the efﬁ cient 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 → 330 mm (Wide)

- A lot more washing can be conveniently added and removed.

330 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 difﬁ cult for strands to enter the holes.
