Troubleshooting measures are classi
fi
ed into the following two types on a remedial basis.
•
Take an appropriate measure according to the symptom.
Not trouble
These cases are not troubles.
•
Check
Please check again before calling a repair person.
•
The air conditioner does not operate.
(OPERATION lamp is off.)
Hasn’t a breaker turned off or a fuse blown?
•
Isn’t it a power failure?
•
Are batteries set in the remote controller?
•
Is the timer setting correct?
•
Hot air does not
fl
ow out soon after
the start of heating operation.
The air conditioner is warming up. You should wait for
•
1 to 4 minutes. (The system is designed to start
discharging air only after it has reached a certain
temperature.)
Operation stopped suddenly.
(OPERATION lamp is on.)
For system protection, the air conditioner may stop
•
operating on a sudden large voltage
fl
uctuation. It
automatically resumes operation in about 3 minutes.
Operation stopped suddenly.
(OPERATION lamp
fl
ashes.)
Are the air
fi
lters clean?
•
Is there anything to block the air inlet or the outlet of
•
the indoor and the outdoor units?
Clean the air
fi
lters or take all obstacles away and turn
•
the breaker off. Then turn it on again and try operating
the air conditioner with the remote controller. If the
lamp still
fl
ashes, call the service shop where you
bought the air conditioner.
Are operation modes all the same for indoor units
•
connected to outdoor units in the
multi system
?
If not, set all indoor units to the same operation mode
and con
fi
rm that the lamps
fl
ash.
Moreover, when the operation mode is in “AUTO”, set
all indoor unit operation modes to “COOL” or “HEAT”
for a moment and check again that the lamps are
normal. If the lamps stop
fl
ashing after the above
steps, there is no malfunction.

Mist comes out of the indoor unit.
This happens when the air in the room is cooled into
•
mist by the cold air
fl
ow during COOL operation.
This is because the air in the room is cooled by the
•
heat exchanger and becomes mist during defrost
operation.
