Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacturer. Any unfi t method or using incompatible material may cause product
damage, burst and serious injury.
Do not install outdoor unit near handrail of veranda. When installing air-conditioner unit on veranda of a high rise building, child may climb up to outdoor unit and cross over the handrail
causing an accident.
Do not use unspecifi ed cord, modifi ed cord, joint cord or extension cord for power supply cord. Do not share the single outlet with other electrical appliances. Poor contact, poor insulation or
over current will cause electrical shock or fi re.
Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.
Do not insert your fi ngers or other objects into the unit, high speed rotating fan may cause injury.
Do not sit or step on the unit, you may fall down accidentally.
Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.
When installing or relocating air conditioner, do not let any substance other than the specifi ed refrigerant, eg. air etc mix into refrigeration cycle (piping). Mixing of air etc. will cause abnormal
high pressure in refrigeration cycle and result in explosion, injury etc.
Do not pierce or burn as the appliance is pressurized. Do not expose the appliance to heat, fl ame, sparks, or other sources of ignition.
Else, it may explode and cause injury or death.
Do not add or replace refrigerant other than specifi ed type. It may cause product damage, burst and injury etc.
•
For R32/R410A model, use piping, fl are nut and tools which is specifi ed for R32/R410A refrigerant. Using of existing (R22) piping, fl are nut and tools may cause abnormally high
pressure in the refrigerant cycle (piping), and possibly result in explosion and injury.
For R32 and R410A, the same fl are nut on the outdoor unit side and pipe can be used.
•
Since the working pressure for R32/R410A is higher than that of refrigerant R22 model, replacing conventional piping and fl are nuts on the outdoor unit side are recommended.
•
If reuse piping is unavoidable, refer to instruction "IN CASE OF REUSING EXISTING REFRIGERANT PIPING"
•
Thickness of copper pipes used with R32/R410A must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.
•
It is desirable that the amount of residual oil less than 40 mg/10 m.
Engage authorized dealer or specialist for installation. If installation done by the user is incorrect, it will cause water leakage, electrical shock or fi re.
For refrigeration system work, install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fi re.
Use the attached accessories parts and specifi ed parts for installation. Otherwise, it will cause the set to fall, water leakage, fi re or electrical shock.
Install at a strong and fi rm location which is able to withstand weight of the set. If the strength is not enough or installation is not properly done, the set will drop and cause injury.
For electrical work, follow the national regulation, legislation and this installation instructions. An independent circuit and single outlet must be used. If electrical circuit capacity is not enough
or defect found in the electrical work, it will cause electrical shock or fi re.
Do not use joint cable for indoor / outdoor connection cable. Use the specifi ed indoor/outdoor connection cable, refer to instruction CONNECT THE CABLE TO THE INDOOR UNIT and connect
tightly for indoor/outdoor connection. Clamp the cable so that no external force will have impact on the terminal. If connection or fi xing is not perfect, it will cause heat up or fi re at the connection.
Wire routing must be properly arranged so that control board cover is fi xed properly. If control board cover is not fi xed perfectly, it will cause fi re or electrical shock.
This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD), with sensitivity of 30 mA at 0.1 sec or less.
Otherwise, it may cause electrical shock and fi re in case of equipment breakdown or insulation breakdown.
During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fi xing refrigeration piping and valves at opened position will cause
suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
During pump down operation, stop the compressor before removing the refrigeration piping. Removal of refrigeration piping while compressor is operating and valves are opened will cause
suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
Tighten the fl are nut with torque wrench according to specifi ed method. If the fl are nut is over-tightened, after a long period, the fl are may break and cause refrigerant gas leakage.
After completion of installation, confi rm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant contacts with fi re.
Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with fi re.
Be aware that refrigerants may not contain an odour.
This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and telephone.
Otherwise, it may cause electrical shock in case of equipment breakdown or insulation breakdown.
Do not install the unit in a place where leakage of fl ammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may cause fi re.

Additional Precautions For R32 Models when connecting by fl aring at indoor side
Ensure to do the re-fl aring of pipes before connecting to units to avoid leaking.
Seal suffi ciently the fl are nut (both gas and liquid sides) with neutral cure (Alkoxy type) & ammonia-free
silicone sealant and insulation material to avoid the gas leak caused by freezing.
Neutral cure (Alkoxy type) & ammonia-free silicone sealant is only to be applied after pressure testing
and cleaning up by following instructions of sealant, only to the outside of the connection. The aim is to
