•  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 and servicing. If installation of servicing 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, electric shock or fire. 

3.   Use the attached accessories parts and specified parts for installation and servicing. Otherwise, it will cause the set to fall, water properly 
      done, the set will drop and cause injury. 

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.   For electrical work, follow the local national wiring standard, regulation and the 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. 

6.   Use the specified cable and connect tightly for indoor/outdoor connection. Connect tightly and 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. 

7.   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 
      heat-up or fire at the connection point of terminal, fire or electrical shock. 
8.   When connecting the piping, do not allow air or any substances other than the specified refrigerant to enter the refrigeration cycle.  
      Otherwise, this may lower the capacity, cause abnormally high pressure in the refrigeration cycle, and possibly result in explosion  
      and injury. 
9.   Thickness of copper pipes used must be more than 0.8 mm. Never use copper thinner than 0.8 mm. 

10. It is desirable that the amount of residual oil is less than 40 mg/10m. 

11. Do not modify the length of the power supply cord or use of the extension cord, and do not share the single outlet with other  
      electrical appliances. Otherwise, it will cause fire or electrical shock. 

 

This indication shows the possibility of causing death or serious injury

1.   The equipment must be earthed. It may cause electrical shock if grounding is not perfect. 

2.   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. 

3.   Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the 
      furniture. 

4.   Pb free solder has a higher melting point than standard solder; typically the melting point is 50°F – 70°F (30°C – 40°C) higher. Please use 
      a high temperature solder iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C). 
      Pb free solder will tend to splash when heated too high (about 1100°F / 600°C). 

 
 

ATTENTION 

1.   Selection of the installation location. Select an installation location which is rigid and strong enough to support or hold the unit, and select a 
      location for easy maintenance. 
2.   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 shall be the place where there is ease for access for the power disconnection in case of emergency. In some countries, 
      permanent connection of this room air conditioner to the power supply is prohibited. 
      i.  Power supply connection to the receptacle using a power plug. Use an approved power plug with earth pin for the connection to the socket.
      ii. Power supply connection to a circuit breaker for the permanent component. Use an approved circuit breaker for the permanent connection.
          It must be a double pole switch with a minimum 3.5 mm contact gap. 
3.   Do not release refrigerant during piping work for installation, servicing, reinstallation and during repairing a refrigerant parts. Take care of 
      the liquid refrigerant, it may cause frostbite. 

4.   Installation work: It may need two people to carry out the installation work. 

5.   Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.
