• Ask your dealer to install in a machine room 

that has no water drops by raining. This unit is 
for indoor use.

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.

• Improper installation or attachment of equip-

ment or accessories could result in electric 
shock, short-circuit, leaks, fire or other dam-
age to the equipment. Be sure only to use 
accessories made by Daikin which are specif-
ically designed for use with the equipment 
and have them installed by a professional.

• Ask your dealer to move and reinstall the air 

conditioner.

Incomplete installation may result in a water leak-
age, electric shock, and fire.

• Never let the indoor unit or the remote control-

ler get wet.

It may cause an electric shock or a fire.

• Never use flammable spray such as hair spray, 

lacquer or paint near the unit.

It may cause a fire.

• Never replace a fuse with that of wrong ampere 

ratings 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.

• Never remove the fan guard of the unit.

A fan rotating at high speed without the fan guard 
is very dangerous.

• Never inspect or service the unit by yourself.

Ask a qualified service person to perform this work.

• Cut off all electric waves before maintenance.

• To avoid the risk of serious electric shock, never 

sprinkle or spill water or liquids on the unit.

• Do not touch the switch with wet fingers.

Touching a switch with wet fingers can cause 
electric shock.

• Do not allow children to play on or around the 

unit as they could be injured.

• The heat exchanger fins are sharp enough to cut.

To avoid injury wear gloves or cover the fins while 
working around them.

• Do not put a finger or other objects into the air 

inlet or air outlet. The fan is rotating at high 
speed and will cause injury.

• Operating the air conditioner with wet hands 

could result in a shock hazard.

• Check the unit stand for damage on a contin-

uous basis, especially if it has been in use for 
a long time.

If left in a damaged condition the unit may fall and 
cause injury.

• Placing a flower vase or other containers with 

water or other liquids on the unit could result 
in a shock hazard or fire if a spill occurs.

• Do not touch the air outlet or horizontal blades 

while the swing flap is in operation because 
fingers could get caught and injured.

• Be sure to establish an earth.

Do not earth the unit to a utility pipe, arrester, or 
telephone earth.
Incomplete earth may cause electrical shock, or fire.
A high surge current from lightning or other 
sources may cause damage to the air conditioner.

• Never touch the internal parts of the controller.

Do not remove the front panel because some parts 
inside are dangerous to touch. In addition, some 
parts may be damaged to touching. For checking 
and adjusting internal parts, contact your dealer.

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.

• Do not place items under the indoor unit 

which may be damaged by water.

Condensation may form if the humidity is above 
80% or if the drain outlet gets blocked.

• 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.

• Never expose little children, plants or animals 

directly to the air flow.

Adverse influence to little children, animals and 
plants may result.

• Do not wash the air conditioner with exces-

sive water.

An electric shock or fire may result.

• Avoid placing the controller in a spot splashed 

with water.

Water coming inside the controller may cause an 
electric leak or may damage the internal elec-
tronic parts.

• Do not operate the air conditioner when using 

a room fumigation - type insecticide.

Failure to observe could cause the chemicals to 
become deposited in the unit, which could endanger the 
health of those who are hypersensitive to chemicals.
