•Do not reconstruct the unit.
Water leakage, fault, short circuit or fire may occur if you reconstruct the unit by
yourself.
•Please ask your sales agent or qualified technician for the installation of your unit.
Water leakage, short circuit or fire may occur if you install the unit by yourself.
•Please use earth line.
Do not place the earth line near water or gas pipes, lightning-conductor, or the earth
line of telephone. Improper installation of earth line may cause electric shock.
•Be sure to use the specified piping set for R410A. Otherwise, this may result in broken
copper pipes or faults.
•A circuit breaker should be installed depending on the mounting site of the unit. Without
a circuit breaker, the danger of electric shock exists.
•Do not install the unit near location where there is flammable gas.
The outdoor unit may catch fire if flammable gas leaks around it. Piping shall be
suitable supported with a maximum spacing of 1m between the supports.
•Please ensure smooth flow of water when installing the drain hose. If any failure is
found in the drain path, water drops from the indoor and outdoor units, causing wet
household effects.
•Make sure that a single phase 230V power source is used.
The use of other power sources may cause electrical components to overheat and lead
to fire.
WARNING
WARNING
CAUTION
•Please read the “Safety Precaution”carefully before operating the unit to ensure correct usage of the unit.
•Pay special attention to signs of “WARNING”and “CAUTION”. The “Warning”section contains matters which, if
not observed strictly, may cause death or serious injury. The “Caution”section contains matters which may result in
serious consequences if not observed properly. Please observe all instructions strictly to ensure safety.
•The signs indicate the following meanings. (The following are examples of signs.)
•Please keep this manual after reading.

PROHIBITION
•Should abnormal situation arise (like burning smell), please stop operating the unit
and remove plug from the socket or turn off the circuit breaker. Contact your agent.
Fault, short circuit or fire may occur if you continue to operate the unit under abnormal
situation.
•Please contact your agent for maintenance.
Improper self maintenance may cause electric shock and fire.
•Please contact your agent if you need to remove and reinstall the unit.
Electric shock or fire may occur if you remove and reinstall the unit yourself improperly.
•Avoid an extended period of direct air flow for your health.
•Do not connect the power cable with an extension cable or do not plug too many leads
of the other electric appliance into the socket where this cable is plugged. In addition,
wire the cable with some allowances to prevent the cable from stretching. Not doing
so will cause an electrical shock, heat generation or fire.
•Do not bundle the power cable, pull it, put something on it, heat it, process it, or put
it between things. Breakage of the power cable may result.
Use of a damaged cable may cause an electrical shock or a fire.
•Do not put objects like thin rods into the panel of blower and suction side because the
high-speed fan inside may cause danger.

•Do not use any conductor as fuse wire, this could cause fatal accident.
•During thunder storm, please stop operating the unit and turn off the circuit breaker.
•Spray cans and other combustibles should not be located within a meter of the air outlets
of both indoor and outdoor units.
As a spray can’s internal pressure can be increased by hot air, a rupture may result.
•The product shall be operated under the manufacturer specification and not for any
other intended use.
•Do not attempt to operate the unit with wet hands. this could cause fatal accident.
•When operating the unit with burning equipments, regularly ventilate the room
to avoid oxygen insufficiency.
•Do not direct the cool air coming out from the air-conditioner panel to face household
heating apparatus as this may affect the working of apparatus such as the electric kettle,
oven etc.
•Please ensure that outdoor mounting frame is always stable, firm and without defect. If
not, the outdoor unit may collapse and cause danger.
•Do not wash the unit with water or place a water container such as a vase on the indoor
unit.
Electrical leakage could be present and cause electric.
•Do not place plants or animals directly under the air flow as it is bad for the plants or
animals.
•Do not climb on the outdoor unit or put objects on it.
•When operating the unit with the door and windows opened, (the room humidity is
always above 80%) and with the air deflector facing down or moving automatically for
a long period of time, water will condense on the air deflector and drips down
occasionally.This will wet your furniture.Therefore, do not operate under such condition
for a long time.
•If the amount of heat in the room is above the cooling or heating capability of the unit (for
example: more people entering the room, using heating equipments and etc.), the preset
room temperature cannot be achieved.
•Indoor unit cleaning must be performed by authorized personnel only. Consult your
sales agent.
Using a commercially available detergent or similar can damage the plastic parts or
clog the drain pipe, causing water to drip with potential electric shock hazard.
•Do not touch the air outlet, bottom surface and aluminum fin of the outdoor
unit.
You may get hurt.
•Do not touch the refrigerant pipe and connecting valve.
Burns may result.

the device beeps twice and the “Two Way Air Exchange”lamp blinks (10 seconds).
While Operating the Two Way Air Exchange
•The two way air exchange is stopped during operation to prevent dew condensation on the two way air exchange fan
and hose and to protect the two way air exchange fan due to changes in the room temperature and outside air temperature.
At this time, the “Two Way Air Exchange”lamp blinks (lights for 10 seconds/out for 1 second) (page 32).
■If the “Two Way Air Exchange”lamp blinks except for the above-mentioned case, the “Two Way Air Exchange”
Fan is abnormal. (Refer page 32)

of about 200 hours, the FILTER lamp
lights indicates that it is time to clean
the filter.The lamp goes out when the
“(AUTO SWING)”button is pressed
while the operation is stopped. But it
does not turn off when self clean is
working.
Operation Lamp (Yellow)
This lamp lights during operation.
The OPERATION LAMP blinks in the following cases during
heating.
