BEFORE CALLING FOR SERVICE

The following conditions do not denote equipment malfunctions
UNIT DOES NOT OPERATE
The unit will not operate if it is turned on
immediately after it is turned off. The unit will not
operate immediately after the mode is changed.
This is to protect the internal mechanisms. Wait 3
minutes before operating the unit.
UNIT DOES NOT SEND OUT WARM AIR
The unit is preheating or de-icing.
ODORS
Carpet and furniture odors that entered into the
unit and the air conditioner's inner component
odors at the early stage of installation may be
sent out from the unit.
CRACKING NOISE
The unit may produce a cracking noise. This sound
is generated by the friction of the front panel and
other components expanding or connecting due to
a temperature change.
A LOW BUZZING NOISE EMITTED
This is a sound emitted when the unit is generating
Plasmacluster ions.
INDOOR UNIT BECOMES WARM
EVEN WHEN IDLE
This is because the refrigerant also fl oes through
the idle indoor unit's pipes when the other unit is
operated in HEAT mode.
INDOOR UNIT BECOMES WARM
EVEN WHEN NOT DURING HEATING
OPERATION
When the PLASMACLUSTER button is pressed
while the unit is not operating, the PLASMA-
CLUSTER operation will be performed without ac-
companying air conditioning mode (eg. HEATING
or COOLING). At this time, you may feel warm air
coming out from the unit air outlet if HEATING is
performed with units in other rooms. Indoor fan
will decrease its rotating speed and will turn ON
and OFF depending on the room temperature.
SWISHING NOISE
The soft, swishing noise is the sound of the re-
frigerant fl owing inside the unit.
WATER VAPOUR
• In the COOL and DRY operation, water va-
pour can sometimes be seen at the air outlet
due to the difference between the room air
temperature and the air discharged by the
unit.
• In the HEAT operation, water vapour may fl ow
out of the outdoor unit during de-icing.
THE OUTDOOR UNIT DOES NOT
STOP
After stopping the operation, the outdoor unit will
rotate its' fan for about a minute to cool down the
unit.
ODOR EMITTED FROM THE PLAS-
MACLUSTER AIR OUTLET
This is the smell of ozone generated from the
Plasmacluster Ion generator. The ozone concen-
tration is very small, posing no adverse effect on
your health. The ozone discharged into the air
rapidly decomposes, and its density in the room
will not increase.
UNIT DOES NOT OPERATE IN YOUR
REQUESTED MODE
• When one indoor unit is operating in COOL or
DRY mode, you can not operate the other unit
in HEAT mode. (After a few seconds, a long
BEEP will be emitted, and the temperature in-
dicator on the indicator panel will indicate"
" and the OPERATION lamp and TIMER lamp
will blink alternately.)
• When one indoor unit is operating in HEAT
mode, you can not operate the other unit in
COOL nor DRY mode. (After a few seconds, a
long BEEP will be emitted, and the temperature
indicator on the indicator panel will indicate"
" and the OPERATION lamp and TIMER lamp
will blink alternately.)
UNIT DOES NOT SEND OUT AIR
(PLASMACLUSTER operation with-
out accompanying air conditioning
mode, SELF CLEAN operation)
The other unit(s) is/are de-icing.
