WHEN YOU THINK THAT TROUBLE HAS OCCURRED
Question
The sound as
burbling is heard.
The room cannot
be cooled
sufficiently.
The air flow
direction changes
during operation.
Water leaks from
the outdoor unit.
Air does not blow
out soon in the
heating operation.
Answer (not a malfunction)
■ This sound is heard when the outside air is absorbed
from the drain hose in turning on the range hood or
the ventilation fan and that makes water flowing in the
drain hose spout out.
This sound is also heard when the outside air blows
into the drain hose in case the outside wind is strong.
■ When a ventilation fan or a gas cooker is used in a
room, the cooling load increases, resulting in an in-
sufficient cooling effect.
■ When the outside air temperature is high, the cooling
effect may not be sufficient.
■ When the air conditioner is operated in COOL or DRY
mode, if the operation continues with air blowing down
for 1 hour, the direction of the air flow is automatically set
to horizontal to prevent condensed water from dropping.
■ In the heating operation, if the air flow temperature is
too low or when defrosting is being done, the HORI-
ZONTAL VANE position is automatically set to hori-
zontal.
■ During COOL and DRY operations, pipe or pipe con-
necting sections are cooled and this causes water to
condense.
■ In the heating operation, the defrosting operation makes
water frozen on the outdoor unit melt and drip down.
■ In the heating operation, water condensed on the heat
exchanger drips down.
■ Please wait as the air conditioner is preparing to blow
out warm air.
Question
The operation is
stopped for about
10 minutes in the
heating operation.
Hissing sound is
sometimes heard.
The room cannot
be heated
sufficiently.
The swing
operation of the
VERTICAL VANE is
suspended for
about 15 seconds,
then restarted.
The air conditioner
starts the operation
only with the main
power turned on,
though you do not
operate the unit
with the remote
controller.
Answer (not a malfunction)
■ Defrosting of the outdoor unit is being done (Defrost-
ing operation).
Since this is completed in 10 minutes, please wait.
(When the external temperature is too low and humid-
ity is too high, frost is formed.)
■ This is the sound when the flow of refrigerant inside
the air conditioner is switched.
■ When the outside air temperature is low, the heating
effect may not be sufficient.
■ This is for the swing operation of the VERTICAL VANE
to be performed normally.
■ This model is equipped with an auto restart function.
When the main power is turned off without stopping
the air conditioner with the remote controller and is
turned on again, the air conditioner will start opera-
tion automatically in the same mode as the one set
with the remote controller just before the shutoff of
the main power.
