Contact the sales dealer or service dealer for a repair and disposal. Provide a power outlet to be used exclusively for each unit, and a power supply disconnect, Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD) for overcurrent protection should be provided in the exclusive line. Provide a power outlet exclusively for each unit, and full disconnection means having a contact separation in all poles must be incorporated in the xed wiring in accordance with the wiring rules. To prevent possible hazards from insulation failure, the unit must be grounded. WARNING Do not use modied cord, joint cord, extension cord or unspecied cord to prevent overheating and re. The appliance shall be stored in a room without continuously operating ignition sources (for example: open ames, an operating gas appliance or an operating electric heater). Be aware that refrigerants may not contain an odour. An unventilated area where the appliance is installed shall be so constructed that should any refrigerant leak, it will not stagnate so as to create a re or explosion hazard. The appliance shall be stored in an area where the room size corresponds to the room area as specied for operation. After the unit is installed, never fail to ask the installer for the oor space of the room where the unit is installed and the refrigerant charge amount. In case the unit or the room divider is changed, never fail to consult the sales dealer or service dealer. Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacturer. Do not pierce or burn. The appliance shall be stored in a room without continuously operating open ames (for example: an operating gas appliance) and ignition sources (for example: an operating electric heater). 00_360661_all.indb 300_360661_all.indb 3 2024/10/07 17:19:262024/10/07 17:19:264 WARNING Stop using the product when any abnormality/failure occurs and disconnect the power plug or turn o󰀨 the power switch and breaker. (Risk of smoke/re/electric shock) Examples of abnormality/failure:

• The ELCB trips frequently.

• The product sometimes does not start when turned on.

• The power is sometimes disconnected when the cord is moved.

• Burnt odor or abnormal noise is detected during operation.

• The body is deformed or abnormally hot.

• Water leaks from the indoor unit.

• Power cord or plug becomes abnormally hot.

• Fan speed cannot be controlled.

• The unit stops running immediately even if it is switched on for operation. Contact immediately your local dealer for maintenance/repair. If refrigerant R32 is used and the optional ‘‘R32 refrigerant leak detector’’ is connected to the indoor unit, do not turn o󰀨 the ELCB of the indoor unit except when there is a symptom of abnormality or failure, or when performing short-term maintenance. (When the ELCB is turned o󰀨, R32 refrigerant leak detector cannot detect the refrigerant leakage when the refrigerant leaks, and it may lead to cause the generation of toxic gases and res.) Do not use the following items near the indoor unit and R32 refrigerant leak detector as they may cause re or false detection of refrigerant leakage.

• Gas equipment that uses ammable gas (propane, methane, etc.)

• Combustible gas such as pesticides and hair spray (LPG, etc.)

• Sprays, drugs, chemicals, paints, etc. that use siloxane. This unit is equipped with a leak detection system for safety. For leak detection to be e󰀨ective, the unit must be electrically powered at all times after installation, other than when servicing. This unit is equipped with electrically powered safety measures. For the safety measures to be e󰀨ective, both the indoor and outdoor units must be electrically powered at all times after installation, other than when servicing. When R32 refrigerant leak detector detects refrigerant leakage, P08 alarm and inspection mark will be displayed on the remote controller, R32 shut o󰀨 valve kit will close if it is connected to the indoor unit, the indoor unit fan will be running to prevent refrigerant stagnation, and it will not stop even if you press the ON/OFF operation button on remote controller. In such a case, do not turn o󰀨 the ELCB, ventilate the room, and contact the service dealer immediately. Also, do not use combustion equipment such as stoves. 00_360661_all.indb 400_360661_all.indb 4 2024/10/07 17:19:272024/10/07 17:19:275 ENGLISH If the alarm display J01 appears, there is something wrong with R32 refrigerant leak detector or its wiring connection to the indoor unit. Contact the service dealer immediately. (It may not be detected when the refrigerant leaks.) When the alarm display J02 appears, it is the end of the life of the sensor board of R32 refrigerant leak detector. Contact the service dealer as soon as possible to replace the sensor board. (If the sensor board is used as it is without being replaced, the sensor may be deteriorated and the refrigerant leakage may not be detected properly.) If the alarm display J07 or J08 appears, there is something wrong with R32 shut o󰀨 valve kit or its wiring connection to the indoor unit. Contact the service dealer immediately. (If R32 shut o󰀨 valve kit cannot work when the refrigerant leaks, all refrigerant in the system may leak and cause re or toxic gases.) 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.

This air conditioner utilizes outside air for heating; its heating performance reduces as outside temperature decreases. → In the event that heating is not su󰀩cient, please use an additional heating appliance.

This appliance may start defrosting operation to melt frost formed in the outdoor unit.

Defrosting starts : The indoor unit fan stops (or the speed becomes extremely slow). ” (STANDBY) appears.

Heating operation resumes after several minutes : The indoor unit fan remains stopped (or it will run at a very slow speed) until the indoor heat exchanger coil warms up su󰀩ciently. ” (STANDBY) appears.

Defrosting is complete : The indoor unit fan starts operation. ” (STANDBY) disappears.

Once the room temperature reaches the level that was set, the outdoor unit repeats the cycle of turning on and o󰀨 automatically. When the room temperature is more likely to reach the level that was set, the fan speed is set to ‘‘breeze’’ (light wind) automatically.

Should power failure occur while the unit is running The unit will resume operation automatically. Operation settings prior to power failure will be used. WARNING

For safety, be sure to turn the air conditioner o󰀨 and disconnect the power before cleaning. (Otherwise, electric shock or injury may result because the fan is rotating at high speed.) Do not pour water on the indoor unit. (This may damage the internal components and cause an electric shock hazard.) CAUTION

Never use solvents or harsh chemicals. Also, do not wipe plastic parts using very hot water. (This may cause deformation or change in colour.) Some metal edges and ns are sharp. Be careful when you clean those parts. (Injury may result.) Use a rm stool or ladder when cleaning an indoor unit installed in high locations. Maintenance
