SAFETY PRECAUTION
•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.
This sign in the figure indicates prohibition. Indicates the instructions that must be followed.
WARNING
CAUTION
•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 a 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.
PROHIBITION

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.

PRECAUTIONS DURING SHIFTING OR MAINTENANCE
“OFF”
PROHIBITION
•Avoid an extended period of direct air flow for your health.
•Do not connect the power calbe 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.
PROHIBITION
•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 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.

WARNING
PRECAUTIONS DURING OPERATION
•Do not use any conductor as fuse wire, this could cause fatal accident.
PROHIBITION
•During thunder storm, disconnect the plug top or 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.

PROHIBITION
•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.
•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 shock.
•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 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.
PROHIBITION

DON’T TOUCH
DON’T TOUCH
•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 automati-
cally 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.
•This appliance especially 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.
•This appliance is not intended for use by young children or infirm persons unless they have been
adequately supervised by a responsible person to ensure that they can use this appliance safely.
•Young children should be supervised to ensure that they do not play with the appliance.

About the outdoor unit:
•When “Stop” is selected during operation
of the indoor unit, the fan of the outdoor
unit continues turning for 10 to 60
seconds to cool the electric parts down.
•In heating operation, condensate or
water due to defrosting will flow.
Do not cover the drain port of the outdoor
unit because such water may freeze in
the chilly area.
•When the outdoor unit is hung on the

NOTE
Notes on batteries
●When replacing the batteries, use batteries of the same
type, and replace both old batteries together.
●When the system is not used for a long time, take the
batteries out.
●The batteries will last for approximately 1 year. However, if
the remote controller display begins to fade and degradation
of reception performance occurs within a year, replace both
batteries with new size AAA.LR03 (alkaline).
●The attached batteries are provided for the initial use of
the system.
The usable period of the batteries may be short depending
on the manufactured date of the air conditioner.
Notes on the remote controller
●Never expose the remote controller to direct sunlight.
●Dust on the signal transmitter or receiver will reduce the
sensitivity. Wipe off dust with soft cloth.
●Signal communication may be disabled if an electronic-
starter-type  uorescent lamp (such as inverter-type lamps)
is in the room. Consult the shop if that is the case.
●If the remote controller signals happen to operate another
appliance, move that appliance to somewhere else, or
consult the service shop.
●When the remote controller is not in use, please close the
slide cover to prevent failure.

AUTOMATIC OPERATION
The device will automatically determine the mode of operation, HEAT or COOL depending on the current
room temperature. The selected mode of operation will change when the room temperature varies.
However, the mode of operation will not change when indoor unit is connected to multi type outdoor unit.
VARIOUS FUNCTIONS
■Auto Restart Control
●If there is a power failure, operation will be automatically restarted when the power is resumed with previous operation
mode and airflow direction.
(As the operation is not stopped by remote controller.)
●If you intend not to continue the operation when the power is resumed, switch off the power supply.
When you switch on the circuit breaker, the operation will be automatically restarted with previous operation mode
and air flow direction.
Note: 1. If you do not require Auto Restart Control, please consult your sales agent.
2. Auto Restart Control is not available when Timer or Sleep Timer mode is set.
Press the MODE selector button so that the display indicates the
(AUTO) mode of operation.
