1. IMPORTANT SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS BEFORE USE
IMPORTANT SAFETY INSTRUCTIONS
¥ Read all instructions before using the washer.
¥ Do not wash articles that have been previously
cleaned in, washed in, soaked in, or spotted with
gasoline, dry cleaning solvents, or other
flammable or explosive substances, as they give
off vapors that could ignite or explode.
¥ Do not add gasoline, dry cleaning solvents, or
other flammable or explosive substances to the
wash water. These substances give off vapors that
could ignite or explode.
¥ Under certain conditions, hydrogen gas may be
produced in a hot water system that has not been
used for 2 weeks or more. HYDROGEN GAS IS
EXPLOSIVE. If the hot water system has not been
used for such a period, before using the washing
machine, turn on all hot water faucets and let the
water flow from each for several minutes. This will
release any accumulated hydrogen gas. As the
gas is flammable, do not smoke or use an open
flame during this time.
¥ Do not allow children to play on or in the washer.
Close supervision of children is necessary when
the washer is used near children.
¥ Before the washer is removed from service or
discarded, remove the door to prevent children
from hiding inside.
¥ Do not install or store the washer where it will be
exposed to the weather.
¥ Do not tamper with controls.
¥ Do not repair or replace any part of the washer or
attempt any servicing unless specifically
recommended in the user-maintenance
instructions or published user-repair instructions
that you understand and have the skills to carry
out.
¥ See Installation Instructions for grounding
requirements.
¥ ALWAYS follow the fabric care instructions
supplied by the garment manufacturer.
¥ Do not place items exposed to cooking oil in your
washer. Items contaminated with cooking oils may
contribute to a chemical reaction that could cause
a load to catch fire.
¥ Do not use fabric softeners or products to
eliminate static unless recommended by the
manufacturer of the fabric softener or product.
WARNING: To reduce the risk of fire, electric shock, or injury to persons when using the washer, follow basic
precautions, including the following:

●Must be within 60″(1.5 m) of either side of the
washer. Do not overload the outlet with more
than one appliance.
●
Time-delay fuse or circuit breaker is recommended.
NOTE: It is the personal responsibility and obligation
of the customer to have a proper outlet
installed by a qualified electrician.
■Level floor
·Allowable slope under entire washer is 1¡.
·To minimize noise and vibration, the washer
MUST be installed on a solidly constructed
floor.
·Carpeting and soft tile surfaces are not
recommended.
·Never install the washer on a platform or
weakly supported structure.
NOTE: A firm, solid floor is even more critical to a
front-loading washer than to a top-loader.
If your floor is wood and/or frame
construction, you may need to reinforce it.
Front-loaders use substantially faster spin
speeds than top-loaders, causing greater
vibration. If the floor is not solid, your washer
will vibrate. You will hear and feel the
vibration throughout your house.
·Connect the power plug to the wall outlet. ·Avoid connecting several electric devices, as
doing so may cause a fire.
■ CONNECT POWER PLUG

■Level adjustment
·Leveling the washing machine properly prevents
excessive noise and vibration.
Install the appliance on a solid and level floor
surface, preferably in a corner of the room.
·If the floor is uneven, adjust the adjustable feet as
required. (Do not insert pieces of wood, etc. under
the feet.)
NOTE: Extend the feet no more than necessary to level
the washer. The more the feet are extended, the
more the washer will vibrate.
·Make sure that all four feet are stable and resting on
the floor and then check that the appliance is
perfectly level (Use a level).
·After the washer is level, tighten the lock nuts up
against of the base of the washer. All lock nuts must
be tightened.
·It is critical to adjust the feet perfectly. This must be
done while the washer is spinning with a load. Use
the wrench (supplied) to adjust the feet until there is
no vibration. Then tighten the lock nuts to prevent
further adjustment.
NOTE: If there is vibration and noise during the spin
cycle, re-check the leveling of the washer, adjust
the feet as required, and tighten the lock nuts
securely to prevent changes in adjustment.
Run the washer with a test load to make certain
your washer is properly leveled. Put an
unbalance weight part in the machine.
You can check noise and/or vibration on high
speed spin rpm through the QC test mode
(refer to page 19).
When the machine spins at high speed, verify
that it is stable. If not, adjust the feet
accordingly.
※Diagonal Check
When pushing down the edges of the washing machine
top plate diagonally, the machine should not move up
and down at all. (Please, check both directions.)

a pressure reducing device should be installed.
· Two sealing washers are supplied with the water
inlet hoses to prevent water leaks.
· Check for leakage of washing machine connections
by turning the tap completely on.
· Periodically check the condition of the hose and
replace the hose if necessary.
· Make sure that there is no kink in the hose and that
it is not crushed.
· Be sure that the two water input ports are connected
to the correct water faucets. The connector for hot
water is colored red; the cold is blue.
Connecting the water supply hoses
Most appliances recommend they be placed upon a dedicated circuit; that is, a single outlet circuit which powers only
that appliance and has no additional outlets or branch circuits. Check the specification page of this owner’s manual to be
certain.
Do not overload wall outlets. Overloaded wall outlets, loose or damaged wall outlets, extension cords, frayed power
cords, or damaged or cracked wire insulation are dangerous. Any of these conditions could result in electric shock or fire.
Periodically examine the cord of your appliance, and if its appearance indicates damage or deterioration, unplug it,
discontinue use of the appliance, and have the cord replaced with an exact replacement part by an authorized servicer.
Protect the power cord from physical or mechanical abuse, such as being twisted, kinked, pinched, closed in a door, or
walked upon. Pay particular attention to plugs, wall outlets, and the point where the cord exits the appliance.
NOTE: Use new hoses when installing a washing machine. Replace them periodically.
Old hoses should not be used.
Do not install your washing machine in a room where temperatures below freezing may occur.
Frozen hoses may burst under pressure. The reliability of the electronic control unit may be impaired
at temperatures below the freezing point.
If the appliance is delivered in the winter months and temperatures are below freezing,
store the washing machine at room temperature for a few hours before putting it into operation.
