Operation Manual

E-22
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.
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.
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.
A LOW BUZZ NOISE EMITTED
This is a sound emitted when the unit is
generating cluster ions.
SWISHING NOISE
The soft, swishing noise is the sound of the
refrigerant flowing inside the unit.
WATER VAPOUR
• In the COOL and DRY operation, water
vapour can sometimes be seen at the air
outlet due to the difference between the
room air temperature and the air dis-
charged by the unit.
• In the HEAT operation, water vapour may
flow 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
PLASMACLUSTER AIR OUTLET
This is the smell of ozone generated from the
ionizer. Density of the ozone is very little, having
no adverse effect over your health. The ozone
released into the air will decompose soon, and its
density in the room will not increase.
During PLASMACLUSTER AUTO
OPERATION, the air conditioner
operates in the REFRESHING OPERA-
TION even when there is odor in the
room.
• In case for example, when the room is
full of tobacco smokes before the air
conditioner is turned on, the ODOR
SENSOR may become unreactive.
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. (4 seconds later,
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.)
• When one indoor unit is operating in HEAT
mode, you can not operate the other unit
in COOL nor DRY mode. (4 seconds later,
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.)
INDOOR UNIT BECOMES WARM EVEN
WHEN NOT DURING HEATING
OPERATION
When the PLASMACLUSTER button is pressed
while the unit is not operating, the
PLASMACLUSTER operation will be performed
without accompanying 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.
(only for models AY-XPM7CR/AY-XPM9CR/AY-XPM12CR)
INDOOR UNIT BECOMES WARM EVEN
WHEN IDLE
This is because the refrigerant also flows
through the idle indoor unit's pipes when the
other unit is operated in HEAT mode.
UNIT DOES NOT SEND OUT AIR
(PLASMACLUTER operation without
accompanying air conditioning mode,
SELF CLEAN operation)
• The other unit(s) is/are de-icing.
