BEFORE CALLING FOR SERVICE
The following conditions do not denote equip-
ment 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
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.
SWISHING NOISE
The soft, swishing noise is the sound of the refrigerant
fl owing 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 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 PLASMACLUSTER
AIR OUTLET
This is the smell of ozone generated from the
Plasmacluster Ion generator. The ozone concentration
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.
When using your air conditioner with multi-
system
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 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.
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 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. (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 without accompanying air conditioning
mode, SELF CLEAN operation)
The other unit(s) is/are de-icing.
If the unit appears to be malfunctioning, check the
following points before calling for service.
IF THE UNIT FAILS TO OPERATE
Check to see if the circuit breaker has tripped or the
fuse has blown.
IF THE UNIT FAILS TO COOL (OR HEAT) THE
ROOM EFFECTIVELY
• Check the fi lters. If dirty, clean them.
• Check the outdoor unit to make sure nothing is
blocking the air inlet or outlet.
• Check the thermostat is proper setting.
• Make sure windows and doors are closed tightly.
• A large number of people in the room can prevent
the unit from achieving the desired temperature.
• Check whether any heat-generating appliances are
operating in the room.
IF THE UNIT FAILS TO RECEIVE THE REMOTE
CONTROL SIGNAL
• Check whether the remote control batteries have
become old and weak.
• Try to send the signal again with the remote control
pointed properly towards the unit’s signal receiver
window.
• Check whether the remote control batteries are
installed with the polarities properly aligned.
Please call for service when TEMPERATURE
INDICATOR on the indicator panel blink.
