Check the following before entrusting any after service.
Presentation Reason
Not Fault
Indoor unit
Sound of flowing water
Sound of flowing water during start, running and short while after stoppage.
Sometimes the sound increases 2-3 minutes after start, it is made by flowing
refrigerant and discharging of condensate water.
"click" sounds
Sometimes the machine makes ìclickî sound during operation because of
changing operation and slight shrinkage of heat exchanger etc.
Blowing with smell
Due to adherence of smell given off by wall, carpet, furniture, clothes, ciga-
rette and cosmetic etc. to air-conditioner.
Running indicator flashes
Indicator flashes when turning on manual power switch after the machine is
reenergized after a power failure.
Displays shows ìstand byî
The machine cannot run cooling model as other indoor unit running heating
mode.
It is displayed when desired operation mode is different with fixed mode that
might be set by air-conditioner controller.
Sounds, white vapor or cool
air during stopping of indoor
unit
To prevent oil or refrigerant detaining in indoor unit being stopped, refriger-
ant flows in short while and makes sounds like ìSha-ì or ìcola-î. In addition,
white vapor sometime comes out when other indoor units are running heating
program while cool air comes if others running cooling program.
Clickî sound while switch-
ing on power of the machine
Sound made by reset eletronic of expansion valve in switching on of the
power.
Please Recheck
The machine runs or stops
automatically
Check whether status of ìtimed power onî or ìtimed power offî has been set.
The machine cannot run
Whether thereís a power failure?
Whether manual power switch is off?
Whether power fuse blows or breaker is off?
Whether protection setting works (running indicator lights)?
Whether timing function works (running indicator lights)?
Whether heating and cooling are selected at the same time (circuit controller
displays ìstand byî)?
Poor heating or cooling effect
Whether inlet and outlet of outdoor unit is blocked?
Whether doors and windows are open?
Whether any dirt or dust obstructs air filter screen?
Whether blowing rate is set to ìslightî, ìlowî? Operation is set to ìblowingî
mode?
Whether temperature is set properly?
Stop running immediately, disconnect manual power switch, and consult after service in the following case:
Poor response to button pressing
Fuse and electric leakage breaker keep on being blown
Machine still cannot run other than reason of protection setting
Sundries or water enters inside of electric box
Other abnormal case

- Note confirm failure code shown on the remote controller shut down power switch and find out reasons after protection setting works check method as seen from check on page 21 continuous operation without solving problems can cause faults of the machine ensure air filter is installed without the filter dust may accumulate on heat exchanger and cause water leakage each indoor unit can run individually or many indoor unit run in meantime however heat and cool operation cannot be run at the same time 7
- Operation features 7
- Operation of fans of units that stop to protect units that stop during running of other indoor unit run their fans for 2 8 minutes at an interval of 30 or 60 minutes 7

- Donít turn on or turn off the machine with manual power switch 8
- Important points of use 8
- In cool operation wind outlet or surface of air guarding plate may have moisture condensation if the air conditioner always drafts air downward for a long period for cassette type 8
- In heat operation heat air may gather below the ceiling and reduce heating effect if the air conditioner always drafts air upward for a long period 8
- Turn on power supply of the outdoor unit 12 hours in priority to running 8
