MEANINGS OF SYMBOLS DISPLAYED ON THE UNIT
WARNING
(Risk of fire)
Read the OPERATION MANUAL carefully before operation.
Service personnel are required to carefully read the OPERATION MANUAL and INSTALLATION MANUAL before operation.
Further information is available in the OPERATION MANUAL, INSTALLATION MANUAL, and the like.
Warning:
• Do not install it by yourself (customer).
Incomplete installation could cause injury due to fire, electric shock, the unit fall-
ing or leakage of water. Consult the dealer from whom you purchased the unit or
special installer.
• Servicing shall be performed only as recommended by the manufacturer.
• For installation and relocation work, follow the instructions in the Installation
Manual and use tools and pipe components specifically made for use with R32
refrigerant. If pipe components not designed for R32 refrigerant are used and the
unit is not installed correctly, the pipes may burst and cause damage or injuries.
In addition, water leakage, electric shock, or fire may result.
• Do not alter the unit. Consult a dealer for repairs. If alterations or repairs are not
performed correctly, water leakage, electric shock, or fire may result.
• This appliance is intended to be used by expert or trained users in shops, in light
industry and on farms, or for commercial use by lay persons.
• Install the unit securely in a place which can bear the weight of the unit.
When installed in an insufficient strong place, the unit could fall causing injured.
• Use the specified wires to connect the indoor and outdoor units securely and
attach the wires firmly to the terminal board connecting sections so the stress of
the wires is not applied to the sections.
Incomplete connecting and fixing could cause fire.
• Do not use intermediate connection of the power cord or the extension cord and
do not connect many devices to one AC outlet.
It could cause a fire or an electric shock due to defective contact, defective insula-
tion, exceeding the permissible current, etc.
• Check that the refrigerant gas does not leak after installation has completed.
• Perform the installation securely referring to the installation manual.
Incomplete installation could cause a personal injury due to fire, electric shock,
the unit falling or leakage of water.
• Use only specified cables for wiring. The wiring connections must be made se-
curely with no tension applied on the terminal connections. Also, never splice the
cables for wiring (unless otherwise indicated in this document).
Failure to observe these instructions may result in overheating or a fire.
• If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid hazard.
• The appliance shall be installed in accordance with national wiring regulations.
• Perform electrical work according to the installation manual and be sure to use an
exclusive circuit.
If the capacity of the power circuit is insufficient or there is incomplete electrical
work, it could result in a fire or an electric shock.
• Attach the electrical part cover to the indoor unit and the service panel to the
outdoor unit securely.
If the electrical part cover in the indoor unit and/or the service panel in the out-
door unit are not attached securely, it could result in a fire or an electric shock
due to dust, water, etc.

This mark is for R32 refrigerant only. Refrigerant type is written on nameplate of outdoor unit.
In case that refrigerant type is R32, this unit uses a flammable refrigerant.
If refrigerant leaks and comes in contact with fire or heating part, it will create harmful gas and there is risk of fire.

• After reading this manual, be sure to keep it together with the instruction
manual in a handy place on the customer's site.
: Indicates a part which must be grounded.
Warning:
Carefully read the labels affixed to the main unit.
/ : Indicates warnings and cautions when using R32 refrigerant.
• Be sure to use the part provided or specified parts for the installation work.
The use of defective parts could cause an injury or leakage of water due to a fire,
an electric shock, the unit falling, etc.
• Ventilate the room if refrigerant leaks during operation.
If the refrigerant comes in contact with a flame, poisonous gases will be released.
• When pumping down the refrigerant, stop the compressor before disconnecting
the refrigerant pipes. The compressor may burst if air etc. get into it.
• When installing or relocating, or servicing the air conditioner, use only the speci-
fied refrigerant (R32) to charge the refrigerant lines. Do not mix it with any other
refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal high pres-
sure in the refrigerant line, and may result in an explosion and other hazards.
The use of any refrigerant other than that specified for the system will cause me-
chanical failure or system malfunction or unit breakdown. In the worst case, this
could lead to a serious impediment to securing product safety.
• Do not use means to accelerate the defrosting process or to clean, other than
those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously operating ignition
sources (for example: open flames, an operating gas appliance or an operating
electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
/ Pipe-work shall be protected from physical damage.
• The installation of pipe-work shall be kept to a minimum.
• Compliance with national gas regulations shall be observed.
• Keep any required ventilation openings clear of obstruction.
/ Do not use low temperature solder alloy in case of brazing the refrigerant pipes.
/ When performing brazing work, be sure to ventilate the room sufficiently.
Make sure that there are no hazardous or flammable materials nearby.
When performing the work in a closed room, small room, or similar location, make
sure that there are no refrigerant leaks before performing the work.
If refrigerant leaks and accumulates, it may ignite or poisonous gases may be
released.
/ The appliance shall be stored in a well-ventilated area where the room size cor-
responds to the room area as specified for operation.
/ Keep gas-burning appliances, electric heaters, and other fire sources (ignition
sources) away from the location where installation, repair, and other air condi-
tioner work will be performed.
If refrigerant comes into contact with a flame, poisonous gases will be released.
/ Do not smoke during work and transportation.
