1. CAUTION ON THE OPERATION
1-1. Safety precautions 
1. MOVING PARTS
Never put your hand into the
spin dryer basket until it has
come to a complete stop.
Also never put your hand into
the wash tub while washing
or rinsing.(Either of these
actions can be extremely
dangerous.)
2. ELECTRIC POWER CORD
• If the power cord is
damaged in any way, it
could cause a malfunction,
an electrical shock, or a fire.
• If the power cord is
damaged, it must only be
replaced by a repair shop
appointed by the
manufacturer, because special purpose tools
are required.
• When unplugging the power cord from the
electrical outlet, always be sure to take hold of
the plug, and never pull on the cord.
• Do not set heavy objects on the power cord and
be careful that the cord does not become
pinched by the washing machine.
3. HOT WATER
Do not use water hotter than 50°C; doing so
could cause damage to some of the plastic parts.
4. WATER AND THE WASHING
MACHINE
CONTROLS
Be careful not to allow
water to come in contact
with the controls of the
washing machine ; doing so
could cause a malfunction or an electrical shock.
5. INFLAMMABLE MATERIALS
Do not put clothing, rags or other materials which
have been soaked in an inflammable substance 
(such as benzene, paint thinner, kerosene, etc.)
into either the wash tub or the spin tub ; doing so
could cause a fire.
6. WHEN NOT IN USE
If the washing machine is not used for a long
period of time, unplug the power cord from the
electrical outlet.
7. HEAT AND FLAME
Many parts of this washing machine are made of
flammable plastics ; never place hot or burning
objects on or near the washing machine.
8. CHILDREN
Guard against small children from playing near or
on the washing machine.
1-2. Servicing precautions
Before attempting to service or adjust any part of
the washing machine, disconnect the electrical
power supply from the wall outlet and remove the
water in the washing machine.
1-3. Installation
1. LOCATION
• Select the installation location.
• Because of the danger of electrical shock, do
not place the washing machine in a location
where it would be exposed to rain or excessive
moisture(such as a steam bath).
• Many of parts of this washing machine are
made of plastic, and could catch fire or become
damaged if exposed to an open flame,
extremely high temperatures, or strong direct
sunlight.
• Place the washing machine on a flat level
surface and allow a clearance of at least 5cm
between the washing machine, walls or other
objects.
• Lower the drain hose so the water drains from 
the open end, and reroute the drain hose
suitable to the position or the washing machine.
• (Pump Model Only)
Place the end of the drain hose in a sink at a
height of no more than 1 meter(standard height:
0.8m).
2. EARTH WIRE CONNECTION
For models with a two-prong plug, be sure to
earth to prevent electrical shock.
• If the water tap and indoor piping are both
metal, wind the earth wire around the base of
the water tap.
• If either the water tap or indoor piping is not
metal, obtain instructions from the dealer how to
bury a ground rod.
• Never connect the earth wire to a gas pipe.
3. POWER SOURCE
• Plug the power cord into an electrical outlet
indicated on specification label.
• Do not plug the washing machine into the same
electrical outlet with other electric appliances.
