CAUTION 
WARNING 
WARNING 
1. Safety Precautions 
•  Read the following “SAFETY PRECAUTIONS” carefully before perform any servicing. 
•  Electrical work must be installed or serviced by a licensed electrician. Be sure to use the correct rating of the 
power plug and main circuit for the model installed. 
•  The caution items stated here must be followed because these important contents are related to safety. The 
meaning of each indication used is as below. Incorrect installation or servicing due to ignoring of the instruction 
will cause harm or damage, and the seriousness is classified by the following indications. 
 
 
This indication shows the possibility of causing death or serious injury 
 
This indication shows the possibility of causing injury or damage to properties. 
 
•  The items to be followed are classified by the symbols: 
 
•  Carry out test run to confirm that no abnormality occurs after the servicing. Then, explain to user the operation, 
care and maintenance as stated in instructions. Please remind the customer to keep the operating instructions for 
future reference. 
 
 
 
1. Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, 
electrical shock or fire. 
 
2.    Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical 
shock or fire. 
 
3.   Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water 
leakage, fire or electrical shock. 
 
4.    Install at a strong and firm location which is able to withstand the set’s weight. If the strength is not enough or 
installation is not properly done, the set will drop and cause injury. 
 
5.    Do not install outdoor unit near handrail of veranda. When installing air-conditioner unit at veranda of high rise 
building, child may climb up to outdoor unit and cross over the handrail and causing accident. 
 
6.    For electrical work, follow the local national wiring standard, regulation and this installation instruction. An independent 
circuit and single outlet must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will 
cause electrical shock or fire. 
 
7.    This equipment is strongly recommended to be installed with Earth Leakage Circuit Breaker (ELCB) or Residual 
Current Device (RCD). Otherwise, it may cause electrical shock and fire in case equipment breakdown or insulation 
breakdown. 
 
8.    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 equipment breakdown or insulation breakdown. 
 
9.    Do not use joint cable for indoor/outdoor connection cable. Use the specified Indoor/Outdoor connection cable, refer 
to installation instructions CONNECT THE CABLE TO THE INDOOR UNIT and connect tightly for indoor / outdoor 
connection. Clamp the cable so that no external force will be acted on the terminal. If connection or fixing is not 
perfect, it will cause heat up or fire at the connection. 
 
10. Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed 
perfectly, it will cause fire or electrical shock. 
 
11.  When carrying out piping connection, take care not to let air substances other than the specified refrigerant go into 
refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion 
and injury. 
 
12. Do not use unspecified cord, modified cord, joint cord or extension cord for power supply cord. Do not share the single 
outlet with other appliances. Poor contact, poor insulation or over current will cause electrical shock or fire. 
 
13. During installation, install the refrigerant piping properly before run the compressor. Operation of compressor without 
fixing refrigeration piping and valves at opened condition will cause suck-in of air,  abnormal high pressure in 
refrigeration cycle and result in explosion, injury etc. 
 
14. During pump down operation, stop the compressor before remove 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. 
 
15. After completion of installation or service, confirm there is no leakage of refrigerant gas. It may generate toxic gas 
when the refrigerant contacts with fire. 
 
16. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant contacts with 
fire. 
 
Symbol with white background denotes item that is PROHIBITED from doing. 
  
   
 
Symbol with dark background denotes item that must be carried out. 
CAUTION 
 
17. Recommended installation height for indoor unit shall be at least 2.5 m. 
 
18. The appliance shall be installed in accordance with national wiring regulations. 
 
19. Keep away from small children, the thin film may cling to nose and mouth and prevent breathing.  
 
20. Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long 
period, the flare may break and cause refrigerant gas leakage. 
 
22. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury. 
 
23. Do not modify the machine, part, material during repairing service. 
 
24.  Must not use other parts except original parts describe in catalog and manual. 
 
 
 
 
1. Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at 
surrounding of the unit, it may cause fire. 
 
2. Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room 
and damage the furniture. 
 
3. Do not touch outdoor unit air inlet and aluminums fin. It may cause injury. 
 
4.  Select an installation location which is easy for maintenance. 
 
5. Power supply connection to the air conditioner. 
Connect the power supply cord of the air conditioner to the mains using one of the following methods. 
Power supply point should be in easily accessible place for power disconnection in case of emergency. 
In some countries, permanent connection of this air conditioner to the power supply is prohibited. 
1) Power supply connection to the receptacle using a power plug. 
Use an approved 15/16A power plug with earth pin for the connection to the receptacle. 
2) Power supply connection to a circuit breaker for the permanent connection. Use an approved 16A circuit breaker for 
the permanent connection. It must be a double pole switch with a minimum 3.5 mm contact gap. 
 
6. Do not release refrigerant. 
Do not release refrigerant during piping work for installation, re-installation and during repairing a refrigeration parts. 
Take care of the liquid refrigerant, it may cause frostbite. 
 
7. Installation or servicing work. 
It may need two people to carry out the installation and service work. 
 
8.   Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.
 
 
9. Do not sit ot step on the unit, you may fall down accidentally. 
 
10. Do not touch the sharp aluminium fin, sharp parts may cause injury.
