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.

• The items to be followed are classified by the symbols:

• Carry out test running 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.

This indication shows the possibility of causing death or serious injury.

This indication shows the possibility of causing injury or damage to properties.

This symbol denotes item that is PROHIBITED from doing.

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

10. 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.

11. After completion of the installation servicing confirm there is no leakage of refrigerant gas. It may generate toxic gas when the

refrigerant contacts with fire.

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

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.
