10.1. Safety Precautions
•
Read this following “SAFETY PRECAUTIONS” carefully before installation.
•
Electrical work must be installed by all licensed electrician. Be sure to use the correct rating of the power plug and main circuit
for the model to be 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 due to ignoring of the instruction will cause harm or damage, and the seriousness is classified by the
following indication.
This indication shows the possibility of causing death or serious injury.
This indication shows the possibility of causing injury or damage to properties only.
The items to be followed are classified by the symbols:
Symbol with background white denotes item that is PROHBITED from piping.
•
Carry out test running to confirm that no abnormality occurs after the installation. Then, explain to user the operation, care and
maintenance as stated in instruction. 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 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. 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 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.
6. Use the specified cable (1.5 mm2) 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 at connection point of terminal, fire or electrical shock.
8. When carrying out piping connection, take care not to let air or other substances other than the specified refrigerant go into refrigeration
cycle. Otherwise, it will cause lower capacity, abnormal high pressure in the refrigerant cycle, explosion and injury.
9. Do not damage or use unspecified power supply cord. Otherwise, it will cause fire or electrical shock.
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.

1. Grounding is necessary. 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.
1. Selection of the installation location.
Select a 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 room air conditioner.
Connect the power supply cord of the room air conditioner to the mains using one of the following method.
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.
1. Power supply connection to the receptacle using a power plug. Use an approved 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 mm contact gap.
3. 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.
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.
