(OPERATION lamp flashes)
• Are the air filters clean?

outdoor units? Clean the air filters or take all obstacles away and turn
the breaker OFF. Then turn it ON again and try operating the air
conditioner with the remote control. If the lamp still flashes, 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 confirm that
the lamps flash.
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 flashing after the above
steps, there is no malfunction.
An abnormal functioning happens during operation.
• The air conditioner may malfunction with lightning or radio waves. Turn
the breaker OFF, turn it ON again and try operating the air conditioner
with the remote control.
