This appliance is not intended for use by persons (including 

children) with reduced physical, sensory or mental 

capabilities, or lack of experience and knowledge, unless 

they have been given supervision or instruction concerning 

use of the appliance by a person responsible for their  

safety.

Children should be supervised to ensure that they do not play 

with the appliance.

The partial units shall only be connected to an appliance suitable 

for the same refrigerant.

The units 8-16kW are partial unit air conditioners, complying 

with partial unit requirements of this International Standard, and 

must only be connected to other units that have been confirmed 

as complying to corresponding partial unit requirements of this 

International Standard.

Ask your dealer for installation of the air conditioner. 

Incomplete installation performed by yourself may result in a 

water leakage, electric shock, and fire. 

Ask your dealer for improvement, repair, and maintenance. 

Incomplete improvement, repair, and maintenance may result in 

a water leakage, electric shock, and fire. 

In order to avoid electric shock, fire or injury, or if you detect 

any abnormality such as smell of fire, turn off the power 

supply and call your dealer for instructions.

Never let the indoor unit or the remote controller get wet. 

It may cause an electric shock or a fire.

Never press the button of the remote controller with a hard, 

pointed object. 

The remote controller may be damaged. 

Never replace a fuse with that of wrong rated current or 

other wires when a fuse blows out. 

Use of wire or copper wire may cause the unit to break down 

or cause a fire. 

It is not good for your health to expose your body to the 

air flow for a long time.

Do not insert fingers, rods or other objects into the air 

inlet or outlet. 

When the fan is rotating at high speed, it will cause injury. 

Never use a flammable spray such as hair spray, 

lacqueror paint near the unit. 

It may cause a fire. 

Never touch the air outlet or the horizontal blades while 

the swing flap is in operation. 

Fingers may become caught or the unit may break down. 

Never put any objects into the air inlet or outlet. 

Objects touching the fan at high speed can be dangerous.

Never inspect or service the unit by yourself. 

Ask a qualified service person to perform this work. 

Do not dispose this product as unsorted 

municipal waste. Collection of such waste 

separately for special treatment is necessary.

Do not dispose of electrical appliances as unsorted municipal 

waste, use separate collection facilities.

Contact you local government for information regarding the 

connection systems available.

If electrical appliances are disposed of in landfills 

or dumps, hazardous substances can leak into the 

groundeater and get into the food chain, damaging your 

health and well-being.

To prevent refrigerant leak, contact your dealer. 

When the system is installed and runs in a small room, it is 

required to keep the concentration of the refrigerant, if by any 

chance coming out, below the limit. Otherwise, oxygen in the 

room may be affected, resulting in a serious accident. 

The refrigerant in the air conditioner is safe and normally 

does not leak. 

If the refrigerant leaks in the room, contact with a fire of a 

burner, a heater or a cooker may result in a harmful gas.

Turn off any combustible heating devices, ventilate the 

room, and contact the dealer where you purchased the 

unit. 

Do not use the air conditioner until a service person confirms 

that the portion where the refrigerant leaks is repaired. 

CAUTION

Do not use the air conditioner for other purposes. 

In order to avoid any quality deterioration, do not use the unit 

for cooling precision instruments, food, plants, animals or 

works of art. 

Before cleaning, be sure to stop the operation, turn the 

breaker off or pull out the supply cord. 

Otherwise, an electric shock and injury may result. 

In order to avoid electric shock or fire, make sure that an 

earth leak detector is installed.

Be sure the air conditioner is grounded. 

In order to avoid electric shock, make sure that the unit is 

grounded and that the earth wire is not connected to gas or 

water pipe, lightning conductor or telephone earth wire.
