ADDITIONAL NOTES ON
OPERATING TEMPERATURE RANGE
• The built-in protective device may prevent the unit
from operating when used out of this range.
• Condensation may form on the air outlet if the unit
operates continuously in the COOL or DRY mode
when humidity is over 80 percent.
WHEN POWER FAILURE OCCURS
This air conditioner has a memory function to store
settings when a power failure occurs.
After power recovery, the unit will automatically re-
start in the same settings which were active before
the power failure, except for timer settings.
If the timers were set before a power failure, they
will need to be re-set after power recovery.
TIPS ON SAVING ENERGY
Below are some simple ways to save energy
when you use your air conditioner.
SET THE CORRECT TEMPERATURE
• Setting the thermostat 1°C higher than the
desired temperature in the COOL mode will save
approximately 10 percent in power consumption.
• Setting the temperature lower than necessary
during cooling operation will result in increased
BLOCK DIRECT SUNLIGHT AND PREVENT
• Blocking direct sunlight during cooling operation
will reduce power consumption.
• Close the windows and doors during cooling
SET PROPER AIR FLOW DIRECTION TO OBTAIN
THE BEST AIR CIRCULATION
KEEP FILTER CLEAN TO ENSURE THE MOST
MAKE MOST OF THE TIMER OFF FUNCTION
DISCONNECT THE POWER CORD WHEN THE
UNIT IS NOT USED FOR AN EXTENDED PERIOD
• The indoor unit still consumes a small amount of
power when it is not operating.
BEFORE CALLING FOR
The following conditions do not denote equip-
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.
Carpet and furniture odors that entered into the unit
may be sent out from the unit.
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
A LOW BUZZING NOISE EMITTED
This is a sound emitted when the unit is generating
The soft, swishing noise is the sound of the
refrigerant ﬂ owing inside the unit.
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.
ODOR EMITTED FROM THE PLASMACLUSTER
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.
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 THE ROOM
• 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
• 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
• Check whether the remote control batteries are
installed with the polarities properly aligned.
Please call for service when OPERATION lamp,
TIMER lamp and/or PLASMACLUSTER lamp on
the unit blink.
