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:

This symbol denotes item that is PROHIBITTED from doing.

• 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 or 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, electrical 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 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. 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. This equipment is strongly recommended to install 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.

7. 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.

8. 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 connection point of terminal, fire or electrical shock.

9. 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, explosive and injury.

10. 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.

11. 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 electric shock in case equipment breakdown or insulation breakdown.

12. 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.

13. Do not damage or use unspecified power supply cord. Otherwise it will cause fire or electric shock.

14. Do not modify the length of the power supply cord or use extension cord, and do not share the single outlet with other electrical

appliances. Otherwise, it will cause fire or electric shock.

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

Thickness of copper pipes used must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.

16. During installation, before run the compressor, confirm the refrigerant pipes are fixed. Operation of compressor without fixing the piping,

setting the valves at open condition, a burst may occur and cause injury.

17. After completion of installation or service, confirm there is no leakage or refrigerant gas. It may generate toxic gas when the refrigerant contacts with fire.

18. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when refrigerant contacts with fire.

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. 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.

4. Do not touch outdoor unit air inlet and aluminium fin. It may cause injury.

5. Select an installation location which is easy for maintenance.

6. 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).

7. 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 connection. Use an approved circuit breaker for the permanent

connection. It must be a double pole switch with a minimum 3.5 mm contact gap.

8. 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.

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

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