1.    IMPORTANT SAFETY INFORMATION

To  prevent  injury  to  the  user  or  other  persons,  as  well  as                               
property damage, the following  instructions must be followed. 
Incorrect  operation  due  to  ingnorance  of  instructions  may 
cause product damage or personal harm.

Consult your dealer for installation of the air conditioner. 

Incomplete installation performed by yourself may result in a 
water leakage, electric shock, or fire. 

Ask your dealer for methods of improvement, repair, and 
maintenance.

 

Improper 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  fire  odors,  turn  off  the 
power supply and call your dealer for more 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  an  incorrectly  rated 
current, or other wires, when a fuse blows out. 

Use  of  wire  or  copper  fuses  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 prolonged period of time.

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

 

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

Never  use  a  flammable  spray,  such  as  hair  spray, 
lacqueror, or 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 within, or the unit may break. 

Never put any objects into the air inlet or outlet.

 

Objects  coming  into  contact  with  the  high  speed  fan  can 
become dangerous.

Never inspect or service the unit by yourself.

 

Ask a qualified service person to perform this work. 

Do  not  dispose  of  this  product  as  unsorted  municipal 
waste.  Separate  collection  of  such  waste  for  special 
treatment is necessary.

Do  not  dispose  of  electrical  appliances  as  unsorted 
municipal waste. Use separate collection facilities.

Contact  your  local  government  for  information  regarding  the 
collection systems available.

If  electrical  appliances  are  disposed  of  in  landfills  or 
dumps,  hazardous  substances  can  eventually  leak  into 
the  groundwater  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  it  leaks,  below  the  limit.  Otherwise,  oxygen  in  the 
room may be affected, resulting in a serious hazard. 

The refrigerant in the air conditioner is safe and normally 
does not leak. 

If the refrigerant leaks inside the room, contact with fire from a 
burner,  heater,  or  cooker  may  result  in  harmful  gas. Turn  off 
any  combustible  heating  devices,  ventilate  the  room,  and 
contact the dealer from where you purchased the unit. Do not 
use the air conditioner until a service person confirms that the 
segment from where the refrigerant leaks is repaired. 

Do not use the air conditioner for abnormal purposes. 

In order to avoid any quality degredation, do not use the unit 
for cooling of precision instruments, food, plants, animals, or 
works of art. 

Before cleaning, be sure to cease operation and turn the 
breaker off or pull out the supply cord. 

Otherwise, an electrical shock and possible injury may result. 

In  order  to  avoid  electric  shock  or  fire,  ensure  that  an 
earth leak detector is installed.

Be sure that 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 a gas or 
water pipe, lightning conductor, or telephone earth wire.

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

The safety precautions listed below are divided into two categories. 
In either case, important safety information is given and must be 
read carefully and complied with.  

 

 

 

 

 

 

 

 

   

 

 

 

 

CAUTION

Failure to observe a caution may result in injury or damage 
to the equipment.

The appliance shall be installed in accordance with nation-
al  wiring  regulations.  Failure  to  observe  a  warning  may 
result in severe injury and/or death.
