INSTALLATION PRECAUTIONS

DANGER

Make sure to have the
installation done by your
dealer or a specialist.

If you install by yourself and the
unit is not properly installed,
water leakage, electric shock,
fire and injuries caused by the
drop of the unit may occur.

ENGLISH

1

The preventive measures
that the density of leaked
refrigerant does not exceed
the limit is necessary in case
of installing the unit in a
small room.

The leakage of refrigerant
may cause oxygen deficiency
accident. Consult your dealer
for the measures.

CAUTION

Make sure to perform
grounding work.

Do not connect grounding wire
to any gas pipe, water pipe,
conductor rods or telephones.
Incomplete grounding may
cause electric shock through
leakage of electricity.

Make sure to mount a
leakage breaker.

Otherwise electric shock may
occur. Please consult your
dealer or a specialist for the
mounting.

Do not mount where
flammable gas leakage
can happen.

If leaked gas stagnates in the
unit, the gas may cause fire.

Make sure to layout the
drain pipe so that the
water is completely drained.

Otherwise, water may leak and
wet household goods.

OPERATION PRECAUTIONS

DANGER

This appliance can be
used by children aged
from 8 years and above
and persons with reduced
physical, sensory or mental
capabilities or lack of
experience and knowledge
if they have been given
supervision or instruction
concerning use of the
appliance in a safe way and
understand the hazards
involved.

Children shall not play
with the appliance.

Cleaning and user
maintenance shall not be
made by children without
supervision.

Do not expose yourself
directly to cooled air flow
for a long time or cool too
much.

It may be cause of
deconditioning or health
disorder.

Do not insert fingers or
sticks into the air inlet or
outlet grilles.

It may cause injuries because
of the fan rotating at high
speed.

If the unit has been
submerged under water
due to a natural disaster
such as flood or typhoon,
consult your dealer before
using it again.

If you use it as it stands, it may
lead to failure, electric shock or
fire.

If any abnormal symptom
(scorched flavor etc.) is
found, cut off the power and
stop the operation.

Then consult your dealer.

If you use it as it stands, it may
lead to failure, electric shock or
fire.

One of the causes of poor
cooling or poor heating
may be refrigerant leakage.
Please consult your dealer.

If the repair requires additional
refrigerant, determine the
service with the service
staff. The refrigerant of air
conditioner is not toxic.
Normally the refrigerant
does not leak. But if it leaks
and contacts fire such as
fan heater, space heater or
cooking heater, it may produce
toxic chemicals.

Do not insert fingers or
sticks even if air blower
does not operate.

It may suddenly operate and
cause injuries.

CAUTION

Do not use for particular
purpose such as the
storage of food, animals and
plants, precision apparatus
and arts etc.

Storage goods may degrade.

Do not operate the button
with wet hand.

It may cause electric shock.

When a burning appliance
is used together with the
unit, ventilate frequently.

If ventilation is not sufficient, it
may cause oxygen deficiency
accident.

Do not place a burning
appliance where the
airflow from the unit is
directly blown.

It may cause the imperfect
combustion of the equipment.

Make sure that the unit
installation foundation is
not damaged due to long­term use.

If it is left to stand, the unit may
fall down causing injury.

Do not wash the unit with
water, nor place a vase
with water on the unit.

It may cause electric shock or
ignition.

2

Do not install the unit
where the airflow is
directly blown to animals and
plants.

They may suffer from adverse
effect.

Before cleaning, make
sure to stop operation
and cut off the power.

The fan inside rotates at high
speeds.

Make sure to use proper
size of fuse.

Using steel wire or copper wire
may lead to failure or fire.

Do not store a flammable
spray etc. near the unit,
nor blow directly to the unit.

It may lead to fire.

Before maintenance,
make sure to stop
operation and cut off the
power.

The fan inside rotates at high
speeds.

When the unit isn’t used
for a long-term, cut off the
power.

The accumulation of dirt may
lead to heat generation or fire.
But, before resuming the
operation, turn on the unit for
six hours beforehand to save
harmless.

Do not place any other
electric appliances or
household goods below or
around the air conditioner.

Dripping from the unit may lead
to failure or contamination.

Do not touch the
aluminum fin.

Otherwise it may lead to
injuries.

Do not clean the inside
of the indoor unit by
yourself. Make sure to
consult your dealer or user
inquiry counter specified by
our company.

If you select incorrect detergent
or improper method, resin
parts may be damaged and
lead to water leakage. If the
detergent is dropped on the
electric component or motor, it
may lead to failure, smoking or
ignition.

Do not place objects on
the outdoor unit, nor
mount on it.

It may lead to injuries resulting
from dropping or falling.

During the operation or
maintenance, do not use
an unstable footrest.

It may lead to injuries resulting
from falling.

Be careful so that the
dust does not get into
your eyes when removing
the air filter.

Do not operate the air
conditioner while the air
filter is removed.

Piled up dust may lead to
malfunction.

During thunderstorm,
stop the operation and
turn off the switch.

A lightning strike may lead to
failure.

After several seasons of
operating, inspections
and maintenances are
required except routine care
and cleaning.

Accumulated dirt or dust inside
the indoor unit may cause odor,
water leakage through the
clogging of water discharging
pipe for dehumidification.
Specialized information
and skills are required for
inspections and maintenances.
Therefore contact your dealer.

Do not place any object
around the outdoor unit,
nor allow fallen leaves to pile
up.

Fallen leaves may induce
insects and worms in them,
and they may lead to failure,
ignition or smoking by touching
electric components.

Do not use with inlet/
outlet grilles or other
panel removed.

Otherwise, it may lead to
injuries.

Do not operate or stop the
unit by using the power
supply switch.

It may lead to fire or water
leakage.
If auto restart is set effectively,
the fan may rotate suddenly
causing injuries.

Do not touch blowout port
when the swing louver
moves.

Otherwise, it may lead to
injuries.

Do not strain the remote
control cord.

A part of core wire may be cut
off causing electric leakage.

Do not use water heater
etc. near the indoor unit
or remote control.

If a Vapor-generating appliance
is used near them, it may lead
to water drop causing electric
leakage or short circuit.

Do not use the unit where
powder or fiber is floating.

Fine powder or fiber passing
through the air filter may
stagnate inside the unit and
lead to electric leak or short
circuit.

Do not place objects
under the unit which
must avoid being exposed to
water.

Over 80 percent humidity or
the clogging of drain pipe may
damage them through dew
dropping.
