1.    PRECAUTIONS

To prevent injury to the user or other people and property 
damage, the following  instructions must be followed. Incorrect 
operation due to ignoring of instructions may cause harm or 
damage. 

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 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.

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.

If the supply cord is damaged, it must be replaced by the 
manufacturer, its service agent or similarly qualified persons 
in order to avoid a hazard.

CAUTION

This appliance is intended to be used by expert or 
trained users in shops, in light industry and on farms, or 
for commercial use by lay persons.

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.

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

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.

Keep far away from high-frequency equipment.

Keep away from the following places: 

a place where it is full of oil gas; places where salty air 
surrounding(near the coast); a place where is caustic gas(the 
sulfide in hotspring). Location in the folling places may cause 
malfunction or shorten the life span of the manchine.

I

n the cace of extremely strong wind, please prevent the 

air from flowing backwards into the outdoor unit.

Snow canopy is necessary in sonwfall places on the 
outdoor unit. Please consult the local dealer for details.

I

n the frequent thunderstruck place, lightning proof 

actions should be taken.

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.

This appliance can be used by children aged from 8 years 
and above and persons with reduced physical, sensory or 
mental capabilities or lack of experience and knowledge if 
they have been given supervision or instruction concerning 
use of the appliance in a safe way and understand the 
hazards involved. Children shall not play with the appliance. 
Cleaning and user maintenance shall not be made by children 
without supervision.
