WARNING
Precaution for appliance filled with R32
Pay careful attention to the following points when operating the appliances and dealing with different refrigerants.

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.
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.
The R32 flare nut and pipe on the outdoor unit side can also be used for a R410A model.

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 extra careful 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.

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.
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.

The following symptoms do not indicate malfunction.
| Symptom | Cause |
| Mist emerges from indoor unit. | Condensation effect due to cooling process. |
| Water flowing sound during operation. | Refrigerant flow inside the unit. |
| The room has a peculiar odour. | This may be due to damp smell emitted by the wall, carpet, furniture or clothing. |
| Indoor fan stops occasionally during automatic fan speed setting. | This helps to remove the surrounding odour. |
| Airflow continues even after operation has stopped. | Extraction of remaining heat from the indoor unit (maximum 30 seconds). |
| Operation is delayed a few minutes after restarting. | The delay is a protection to the unit's compressor. |
| Outdoor unit emits water/steam. | Condensation or evaporation occurs on pipes. |
| TIMER indicator is always on. | The timer setting repeats daily once set. |
| POWER indicator blinks during HEAT mode with no warm air supply (and flap is closed). | The unit is in defrost mode (and AIR SWING is set to AUTO). |
| Indoor fan stops occasionally during heating operation. | To avoid unintended cooling effect. |
| POWER indicator blinks before the unit is switched on. | This is a preliminary step in preparation for the operation when the ON timer has been set. When ON Timer is set, the unit may start earlier (up to 35 minutes) before the actual set time in order to achieve the desired temperature on time. |
| Cracking sound during operation. | Changes of temperature caused the expansion/contraction of the unit. |
| Dusts accumulated on the wall. | Due to air circulation or static electricity generated by the air conditioner. Some types of wall paper may collect dusts easily (recommended to clean the area around the air conditioner frequently). |
| During COOL/DRY mode, the indoor unit stops and POWER indicator blinks. | The system has locked to operate in HEAT model only. |
| Discoloration of some plastic parts. | Discoloration is subject to material types used in plastic parts, accelerated when exposed to heat, sun light, UV light or environmental factor. |
| Cooling/heating capacity reduced during the lowest fan speed setting. | The low fan speed is low noise priority operation, so cooling/heating capacity may be reduced (depending on the condition). Increase the Fan Speed to increase the capacity. |
Check the following before calling for servicing.
| Symptom | Check |
| Operation in HEAT/COOL mode is not working efficiently. | Set the temperature correctly.Close all doors and windows.Clean or replace the filters.Clear any obstruction at the air inlet and air outlet vents. |
| Noisy during operation. | Check if the unit has been installed at an incline.Close the front panel properly. |
| Remote control does not work. (Display is dim or transmission signal is weak.) | Insert the batteries correctly.Replace weak batteries. |
| The unit does not work. | Check if the circuit breaker is tripped.Check if timers have been set. |
| The unit does not receive the signal from the remote control. | Make sure the receiver is not obstructed.Certain fluorescent lights may interfere with signal transmitter. Please consult authorised dealer. |
