● OPERATING INSTRUCTIONS ●

Even if these items are checked, when the unit does not recover from the 

trouble, stop using the air conditioner and consult your dealer.

Symptom

Explanation & Check points

Indoor Unit

The unit cannot be operated.

•  Is the breaker turned on?

•  Is the power supply plug connected?

•  Is the ON timer set? 

 Page 6 

All LED lamps on the indoor 

unit are blinking.

•  Are the horizontal vanes installed correctly? 

 Page 8 

The horizontal vane does not 

move.

•  Are the horizontal vane and the vertical vane 

installed correctly? 

 Page 8 

•  Is the fan guard deformed?

The unit cannot be operated for 

about 3 minutes when restarted.

•  This  protects  the  unit  according  to  instruc-

tions from the microprocessor. Please wait.

Mist is discharged from the air 

outlet of the indoor unit.

•  The cool air from the unit rapidly cools mois-

ture in the air inside the room, and it turns 

into mist.

The swing operation of the 

HORIZONTAL VANE is 

suspended for a while, then 

restarted.

•  This is for the swing operation of the HORI-

ZONTAL VANE to be performed normally.

The airfl ow direction changes 

during operation.

The direction of the horizontal 

vane cannot be adjusted with 

the remote controller.

•  When the unit is operated in COOL or DRY 

mode,  if  the  operation  continues  with  air 

blowing down for 0.5 to 1 hour, the direction 

of the airfl ow is automatically set to horizon-

tal position to prevent water from condensing 

and dripping.

•  In the heating operation, if the airfl ow tem-

perature is too low or when defrosting is be-

ing done, the horizontal vane is automatically 

set to horizontal position.

The operation stops for about 

10 minutes in the heating 

operation.

•  Outdoor unit is in defrost.

  Since  this  is  completed  in  max.  10  minutes, 

please wait. (When the outside temperature is too 

low and humidity is too high, frost is formed.)

The unit starts operation by 

itself when the main power is 

turned on, but isn’t received 

sign from the remote control-

ler.

•  These models are equipped with an auto re-

start function. When the main power is turned 

off without stopping the unit with the remote 

controller  and  is  turned  on  again,  the  unit 

starts  operation  automatically  in  the  same 

mode as the one set with the remote control-

ler just before the shutoff of the main power. 

Refer to “Auto restart function”

.

In COOL/DRY mode, 

when the room tempera-

ture reaches near the set 

temperature, the outdoor 

unit stops, then the indoor 

fan also stops running. The 

indoor fan alternates ON and 

OFF afterward.

•  The  indoor  fan  stops  running  at  the  set 

temperature to reduce power consumption. 

A  couple  minutes  afterward,  however,  the 

indoor fan operates at low speed for some 

seconds  at  regular  intervals  to  sense  ac-

curate  room  temperature.  When  the  room 

temperature rises and the outdoor unit turns 

on, the indoor fan starts running according 

to the settings on the remote controller.

The indoor unit discolors over 

time.

•  Although plastic turns yellow due to the infl u-

ence of some factors such as ultraviolet light 

and  temperature,  this  has  no  effect  on  the 

product functions.

Multi system

The indoor unit which is not 

operating becomes warm and 

a sound, similar to water fl ow-

ing, is heard from the unit.

•  A  small  amount  of  refrigerant  continues  to 

fl ow into the indoor unit even though it is not 

operating.

When heating operation is 

selected, operation does not 

start right away.

•  When operation is started during defrosting 

of outdoor unit is done, it takes a few minutes 

(max. 10 minutes) to blow out warm air.

Outdoor Unit

The fan of the outdoor unit 

does not rotate even though 

the compressor is running. 

Even if the fan starts to rotate, 

it stops soon.

•  When  the  outside  temperature  is  low  dur-

ing  cooling  operation,  the  fan  operates 

intermittently  to  maintain  suffi cient  cooling 

capacity.

Water leaks from the outdoor 

unit.

•  During COOL and DRY operations, pipe or 

pipe connecting sections are cooled and this 

causes water to condense.

•  In  the  heating  operation,  water  condensed 

on the heat exchanger drips down.

•  In  the  heating  operation,  the  defrosting 

operation makes ice forming on the outdoor 

unit melt and drip down.

White smoke is discharged 

from the outdoor unit.

•  In the heating operation, vapor generated by the 

defrosting operation looks like white smoke.

Symptom

Explanation & Check points

Remote controller

The display on the remote 

controller does not appear 

or it is dim. The indoor unit 

does not respond to the 

remote control signal.

•  Are the batteries exhausted? 

 Page 3 

•  Is the polarity (+, -) of the batteries correct?

 Page 3 

•  Are  any  buttons  on  the  remote  controller  of 

other electric appliances being pressed?

Does not cool or heat

The room cannot be cooled 

or heated suffi ciently.

•  Is  the  temperature  setting  appropriate? 

 Page 4 

•  Is the fan setting appropriate? Please change 

fan speed to higher setting. 

 Page 5 

•  Are the fi lters clean? 

 Page 8 

•  Is the fan or heat exchanger of the indoor unit 

clean? 

 Page 8 

•  Are there any obstacles blocking the air inlet 

or outlet of the indoor or outdoor unit?

•  Is a window or door open?

The room cannot be cooled 

suffi ciently.

•  When  a  ventilation  fan  or  a  gas  cooker  is 

used in a room, the cooling load increases, 

resulting in an insuffi cient cooling effect.

•  When  the  outside  temperature  is  high,  the 

cooling effect may not be suffi cient.

The room cannot be heated 

suffi ciently.

•  When  the  outside  temperature  is  low,  the 

heating effect may not be suffi cient.

Air does not blow out soon in 

the heating operation.

•  Please wait as the unit is preparing to blow 

out warm air.

Airfl ow

The air from the indoor unit 

smells strange.

•  Are the fi lters clean? 

 Page 8 

•  Is the fan or heat exchanger of the indoor unit 

clean? 

 Page 8 

•  The unit may suck in an odor adhering to the 

wall, carpet, furniture, cloth, etc. and blow it 

out with the air.

Sound

Cracking sound is heard.

•  This  sound  is  generated  by  the  expansion/

contraction  of  the  front  panel,  etc.  due  to 

change in temperature.

“Burbling” sound is heard.

•  This sound is heard when the outside air is 

absorbed from the drain hose by turning on 

the range hood or the ventilation fan, making 

water fl owing in the drain hose to spout out.

  This sound is also heard when the outside air 

blows into the drain hose in case the outside 

wind is strong.

Mechanical sound is heard 

from the indoor unit.

•  This is the switching sound in turning on/off 

the fan or the compressor.

The sound of water fl owing 

is heard.

•  This is the sound of refrigerant or condensed 

water fl owing in the unit.

Hissing sound is sometimes 

heard.

•  This is the sound when the fl ow of refrigerant 

inside the unit is changed.

Timer

Weekly timer does not oper-

ate according to settings.

•  Is the ON/OFF timer set?  

 Page 6 

•  Transmit the setting information of the weekly 

timer to the indoor unit again. When the infor-

mation is successfully received, a long beep 

will sound from the indoor unit. If information 

fails  to  be  received,  3  short  beeps  will  be 

heard.  Ensure  information  is  successfully 

received. 

 Page 7 

•  When  a  power  failure  occurs  and  the  main 

power turns off, the indoor unit built-in clock 

will be incorrect. As a result, the weekly timer 

may not work normally.

  Be sure to place the remote controller where 

the signal can be received by the indoor unit.

 Page 3 

The unit starts/stops the 

operation by itself.

•  Is the weekly timer set? 

 Page 7

In the following cases, stop using the air conditioner and consult your dealer.

•  When water leaks or drips from the indoor unit.

•  When the upper operation indicator lamp blinks.

•  When the breaker trips frequently.

•  The remote control signal is not received in a room where an electronic ON/OFF 

type fl uorescent lamp (inverter-type fl uorescent lamp, etc.) is used.

•  Operation of the air conditioner interferes with radio or TV reception. An ampli-

fi er may be required for the affected device.

•  When an abnormal sound is heard.
