This symbol is only for R32 refrigerant. The type of the refrigerant used is written on the nameplate on the outdoor unit.
(Risk of fire)
R32 refrigerant is flammable. If the refrigerant leaks, or comes in contact with fire or parts that generate heat, it may create
harmful gas and pose a 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.

Symbols used in the illustrations
: Indicates a part which must be grounded.
• Do not install the unit in a place where smoke or gas can migrate
to, or where chemical solution can drip on.
- Do not use any of the following near the indoor unit: Propane,
butane, or methane appliances; spray cans, such as insect
repellant; or paint.
- These items can trigger the refrigerant sensor, which will be
displayed as an error, and the unit may become inoperable.
• When non-cooling or non-heating problem occurs, refrigerant
leakage is suspected. Leave the breaker on, ventilate the room,
and consult your dealer. For detailed information about a repair
involving replenishing the unit with refrigerant, consult your
service technician.
- The refrigerant used for the air conditioner is nontoxic and normally
stays contained within the system. However, if it leaks out and
comes in contact with the components of such appliances as
fan heaters, kerosene heaters, and grills that heat up, toxic and
flammable gas will be generated, which poses a risk of fire.
• If a refrigerant leakage occurs, turn off the appliances in the
space, and open the windows to ventilate the room. Then, contact
your dealer.
• The indoor unit is designed to disperse leaked refrigerant when
operated in the FAN mode, reducing the occurrence of fire. Leave
the breaker on when this function is being activated.
