1PRECAUTIONS FOR SAFETY
The manufacturer shall not assume any liability for the damage caused by not observing the description of this manual.
WARNING
General
• Carefully read Owner’s Manual before starting the air conditioner. There are many important things to keep in mind
for daily operation.
• Do not use any refrigerant different from the one specified forcomplement or replacement. Otherwise, abnormally
high pressure may be generated in the refrigeration cycle, which may result in a failure or explosion of the product or
an injury to your body.
Transportation and storage
• When transporting the air conditioner, wear shoes with additional protective toe caps.
• When stacking the packing cartons for storage or transportation, heed the precautions written on the packing cartons.
Failure to heed the precautions may cause the stack to collapse.
• When transporting the air conditioner, transport it by two people or more.
Installation
• Only a qualified installer(*1) or qualified service person(*1) is allowed to install the air conditioner. If the air conditioner
is installed by an unqualified individual, a fire, electric shocks, injury, water leakage, noise and/or vibration may result.
• After the installation work has been completed, have the installer explain about the circuit breaker positions. In the
event that trouble has occurred in the air conditioner, set the circuit breaker to the OFF position, and contact a
service person.
• If you install the unit in a small room, take appropriate measures to prevent the refrigerant from exceeding the limit
concentration even if it leaks. Consult the dealer from whom you purchased the air conditioner when you implement
the measures. Accumulation of highly concentrated refrigerant may cause an oxygen deficiency accident.
• Do not install the air conditioner in a location that may be subject to a risk of exposure to a combustible gas. If a
combustible gas leaks and becomes concentrated around the unit, a fire may occur.
Operation
• Before opening the front panel of the indoor unit or service panel of the outdoor unit, set the circuit breaker to the
OFF position. Failure to set the circuit breaker to the OFF position may result in electric shocks through contact with
the interior parts. Only a qualified installer(*1) or qualified service person(*1) is allowed to remove the front panel of
the indoor unit or service panel of the outdoor unit and do the work required.
• Inside the air conditioner are high-voltage areas and rotating parts. Due to the danger of electric shocks or of your
fingers or physical objects becoming trapped in the rotating parts, do not remove the front panel of the indoor unit
or service panel of the outdoor unit. When work involving the removal of these parts is required, contact a qualified
installer or a qualified service person.
• Do not move or repair any unit by yourself. Since there is high voltage inside the unit, you may get electric shock
when removing the cover and main unit.
• Never insert a stick into the air intake or outlet. Doing so may result injury as the fan is rotating at high speed inside
the unit.
• Do not expose your body to cool air directly for a long time and do not cool yourself excessively. Doing so may result
in deteriorated physical condition and ill health.
• Do not touch the aluminum fin of the unit. You may injure yourself if you do so. If the fin must be touched, do not
touch it yourself but contact a qualified installer or a qualified service person.
• Do not spill water or other liquid on the indoor unit. If the unit is wet, it may cause an electric shock.
• Do not place any combustion appliance in a place where it is directly exposed to the wind of air conditioner, otherwise
it may cause imperfect combustion.
• When the air conditioner is operated with a combustion appliance in the same place, be careful of ventilation to let
fresh air enter the room. Poor ventilation causes oxygen shortage.
• When the air conditioner is used in a closed room, be careful of sufficient ventilation of the room. Poor ventilation
causes oxygen shortage.
Repairs
• When you have noticed that some kind of trouble (such as when an error display has appeared, there is a smell of
burning, abnormal sounds are heard, the air conditioner fails to cool or heat or water is leaking) has occurred in the
air conditioner, do not touch the air conditioner yourself but set the circuit breaker to the OFF position, and contact a
qualified service person. Take steps to ensure that the power will not be turned on (by marking “out of service” near
the circuit breaker, for instance) until qualified service person arrives. Continuing to use the air conditioner in the
trouble status may cause mechanical problems to escalate or result in electric shocks, etc.
• If you have discovered that there is a danger of the indoor unit’s falling, do not approach the indoor unit but set the
circuit breaker to the OFF position, and contact a qualified installer or a qualified service person to refit the unit. Do
not set the circuit breaker to the ON position until the unit has been refitted.
• Do not modify the products. Do not also disassemble or modify the parts. It may cause a fire, electric shock or injury.
Relocation
• When the air conditioner is to be relocated, do not relocate it yourself but contact a qualified installer or a qualified
service person. Failure to relocate the air conditioner properly may result in electric shocks and/or a fire.
(*1) Refer to the “Definition of Qualified Installer or Qualified Service Person.”

CAUTION
CAUTIONS ABOUT INSTALLATION
• Certainly lay the drain hose for perfect draining.
Wrong drainage may cause flooding in the house and getting furniture wet.
• Make sure to connect the air conditioner to an exclusive power supply of the rated voltage; otherwise, the unit
may break down or cause a fire.
CAUTIONS ABOUT OPERATION
• Carefully read this manual and the manual supplied with the outdoor unit before starting the air conditioner. The
manual includes many important things for daily operation.
• Do not use this air conditioner for other purposes such as preserving food, precision instruments, art objects,
breeding animals, growing potted plants, etc.
• Do not install this air conditioner in a special-purpose room such as a ship or any kind of vehicle, otherwise it
deteriorates the machine performance.
• Avoid exposing potted plants and animals to wind of the air conditioner, because it badly affects the health and
growing of them.
• When the air conditioner is operated together with a combustion appliance in the same place, be careful of
ventilation to let fresh air into the room.
Poor ventilation causes oxygen shortage.
• Do not touch operation button with wet finger; otherwise, you may get an electric shock.
• When the air conditioner won’t be used for a considerably long time, turn off the main switch or the circuit breaker,
for safety. Disconnection from the power supply prevents the unit from lightning and power source surge.
• Do not put a vessel with water such as a vase on the unit, because water may possibly sink into the unit and will
bring about electric shock because of deterioration in electric insulation.
• Do not wash the unit with water. It may cause an electric shock.
• Do not use alcohol, benzene, thinner, glass cleaner, polishing powder, etc. for cleaning the unit, because they
deteriorate or damage the air conditioner.
• When cleaning the unit, make sure to turn off the main switch or circuit breaker beforehand for preventing you
from getting injured by the electric fan running inside.
For details of cleaning method, refer to “Maintenance”.
• To make the air conditioner demonstrate its original performance, operate it within the range of the operating
temperature specified in the instructions.
Otherwise it may malfunction, break down or water may leak from the unit.

CAUTION
When using indoor unit in group control,
1. Hi-POWER operation will not function.
When Hi-POWER is transmitted from wireless remote controller the receiving sound will be heard from the indoor
unit and display on the wireless remote controller will also change. However, the indoor unit does not operate
Hi-POWER operation. Restore the display on the wireless remote controller pushing Hi-POWER button.
2. COMFORT SLEEP
When COMFORT SLEEP is transmitted from wireless remote controller, the receiving sound will be heard from
the indoor unit and the display on the wireless remote controller will also be changed as same as Hi-POWER
operation. However, the set temperature and the fan speed will not be automatically adjusted. Only off timer
function is activated.
3. Units other than the Header unit cannot be operated with remote controller and the TEMPORARY operation.

Header and follower indoor units are decided through address setting upon installation. Follower unit will not
receive any signals from wireless remote controller.
Air conditioner will not work even if the button on the follower unit is pressed.
(Some Follower units may receive SWING and FIX, but these operations are performed only on the unit that
received the signal.)
(When wireless remote controller is used, only the Header unit receives SWING signal. If the SWING signal is
transmitted to follower unit, the sound to refuse receiving signal (3 beeps) is heard and the follower unit does not
receive the signal.
For FIX operation, both Header and follower unit perform the operation by itself.
When wired remote controller is used, airflow direction can be changed on each unit by selecting the indoor unit.)
4. TIMER lamp lights up only on the Header unit.
When the timer is set with wired remote controller, even the TIMER lamp on the Header unit will not light up.
