These symbols denote actions

Indoor unit and outdoor unit

This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision. The appliance shall be installed, and/or operated in a room with floor area larger than Amin (m²) and keep away from ignition sources, such as heat/sparks/ open flame or hazardous areas such as gas appliances, gas cooking, reticulated gas supply systems or electric cooking appliances, etc. (Refer to Table A of Installation instructions table for Amin (m²)) Be aware that refrigerant may not contain an odour, highly recommended to ensure suitable flammable refrigerant gas detectors are present, operating and able to warn of a leak. Please consult authorised dealer or specialist to clean the internal parts, repair, install, remove and reinstall the unit. Improper installation and handling will cause leakage, electric shock or fire. Confirm with authorised dealer or specialist on usage of any specified refrigerant type. Using refrigerant type other than the specified may cause product damage, burst and injury etc.

Do not install the unit in a potentially explosive or flammable atmosphere.

Failure to do so could result in fire. Do not insert your fingers or other objects into the air conditioner indoor or outdoor unit, rotating parts may cause injury. Do not touch the outdoor unit during lightning, it may cause electric shock. Do not expose yourself directly to cold air for a long period to avoid excess cooling. Do not sit or step on the unit, you may fall down accidentally.

Do not allow infants and small children to play with the remote control to prevent them from accidentally swallowing the batteries.

Do not use a modified cord, joint cord, extension cord or unspecified cord to prevent overheating and fire.

If the supply cord is damaged, it must be replaced by the manufacturer, service agent or similarly qualified persons in order to avoid a hazard.

It is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD) to prevent electric shock or fire. To prevent overheating, fire or electric shock: • Insert the power plug properly. • Dust on the power plug should be periodically wiped with a dry cloth.

Do not pierce or burn as the appliance is pressurized. Do not expose the appliance to heat, flame, sparks, or other sources of ignition. Else it may explode and cause injury or death.

To prevent overheating, fire or electric shock:

• Do not share the same power outlet with other equipment. • Do not operate with wet hands. • Do not over bend the power supply cord. • Do not operate or stop the unit by inserting or pulling out the power plug.

Do not use means to accelerate the defrosting process or to clean, other than those recommended by manufacturer.

Any unfit method or using incompatible material may cause product damage, burst and serious injury.

Stop using the product if any abnormality/ failure occurs and disconnect the power plug or turn off the power switch and breaker.

(Risk of smoke/fire/electric shock) Examples of abnormality/failure • The ELCB trips frequently. • Burning smell is observed. • Abnormal noise or vibration of the unit is observed. • 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. • The fan does not stop even if the operation is stopped. Contact your local dealer immediately for maintenance/repair. This equipment must be earthed to prevent electrical shock or fire.

Prevent electric shock by switching off the power supply and unplug: - Before cleaning or servicing, - When extended non-use, or - During abnormally strong lightning activity.

Precaution for using R32 refrigerant

Pay careful attention to the following points when operating the appliances and dealing with different refrigerants. Since the working pressure is higher than that of refrigerant R22 models, some of the piping and installation and service tools are special. Especially, when replacing a refrigerant R22 model with a new refrigerant R32 model, always replace the conventional piping and flare nuts with the R32 and R410A piping and flare nuts on the outdoor unit side. For R32 and R410A, the same flare nut on the outdoor unit side and pipe can be used. Models that use refrigerant R32 and R410A have a different charging port thread diameter to prevent erroneous charging with refrigerant R22 and for safety. Therefore, check beforehand. [The charging port thread diameter for R32 and R410A is 12.7 mm (1/2 inch).] Be more careful than R22 so that foreign matter (oil, water, etc.) does not enter the piping. Also, when storing the piping, securely seal the opening by pinching, taping, etc. (Handling of R32 is similar to R410A.) This appliance shall be stored in a well ventilated area. This appliance shall be stored in a room without continuously operating open flames and ignition sources. This appliance shall be stored so as to prevent mechanical damage from occurring.

CAUTION Indoor unit and outdoor unit

Do not wash the indoor unit with water, benzine, thinner or scouring powder to avoid damage or corrosion at the unit. Do not use for preservation of precise equipment, food, animals, plants, artwork or other objects. This may cause quality deterioration, etc. Do not use any combustible equipment in front of the airflow outlet to avoid fire propagation. Do not expose plants or pet directly to airflow to avoid injury, etc. Do not touch the sharp aluminium fin, sharp parts may cause injury. Do not switch ON the indoor unit when waxing the floor. After waxing, aerate the room properly before operating the unit. Do not install the unit in oily and smoky areas to prevent damage to the unit. Do not dismantle the unit for cleaning purpose to avoid injury. Do not step onto an unstable bench when cleaning the unit to avoid injury. Do not place a vase or water container on the unit. Water may enter the unit and degrade the insulation. This may cause an electric shock. Do not open window or door for long time during operation, it may lead to inefficient power usage and uncomfortable temperature changes.

After a long period of use, make sure the installation rack does not deteriorate to prevent the unit from falling down.

Do not use rechargeable (Ni-Cd) batteries. It may damage the remote control. To prevent malfunction or damage of the remote control: • Remove the batteries if the unit is not going to be used for a long period of time. • New batteries of the same type must be inserted following the polarity stated.

After a long period of use or use with any combustible equipment, aerate the room regularly.

Prevent water leakage by ensuring drainage pipe is:

- Connected properly, - Kept clear of gutters and containers, or - Not immersed in water

Do not disconnect the plug by pulling the cord to prevent electric shock.
