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 put any objects into the air inlet or outlet.

Objects touching the fan at high speed can be dangerous.

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  heat  pump  is  safe  and  normally 

does not leak. 

Ask your dealer for installation of the heat pump. 

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.

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. 

Do not use the heat pump 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 heat pump 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 

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 heat pump until a service person confirms that 

the portion where the refrigerant leaks is repaired. 

water pipe, lightning conductor or telephone earth wire.

In order to avoid injury, do not remove the fan guard of 

the outdoor unit.

Do not operate the heat pump with a wet hand. 

An electric shock may happen. 

Do not touch the heat exchanger fins. 

These fins are sharp and could result in cutting injuries.

Do not place items which might be damaged by moisture 

under the indoor unit. 

Condensation may form if the humidity is above 80%, the 

drain outlet is blocked or the filter is polluted. 

After a long use, check the unit stand and fitting for 

damage.

If damaged, the unit may fall and result in injury.

To avoid oxygen deficiency, ventilate the room 

sufficiently if equipment with burner is used together 

with the heat pump.

Arrange the drain hose to ensure smooth drainage.

Incomplete drainage may cause wetting of the building, 

furniture etc.

Never touch the internal parts of the controller.

Do not remove the front panel. Some parts inside are 

dangerous to touch, and a machine trouble may happen.

Never do the maintenances work by yourself.

Please contact your local dealer to do the maintenances 

work.
