Power failure
Power failure during operation will stop the unit completely.
The OPERATION lamp on the indoor unit will start
flashing when power is restored.
To restart operation, push the ON/OFF button on the

Lighting or a car wireless telephone operating nearby

4. HINTS FOR ECONOMICAL OPERATION
The following should be noticed to ensure an economical
operation. (Refer to corresponding chapter for details)
Adjust the air flow direction properly to avoid air blowing
toward your body.
Adjust the room temperature properly to get a comfortable
environment and to avoid supercooling and superheat.
In cooling, close the curtains to avoid direct sunlight.
To keep cool or warm air in the room, never open doors or
windows more often than necessary.
Set the timer for the desired operating time.
Never put obstructions near the air outlet or the air inlet. Or it
will cause lower efficiency, even a sudden stop.
If you don't plan to use the unit for a long time, please
disconnect power and remove the batteries from the remote
controller. When the power switch is connected, some
energy will be consumed, even if the air conditioner isn't in
operation. So please disconnect the power to save energy.
And please switch the power on 12 hours before you
restart the unit to ensure smooth operation.
A clogged air filter will reduce cooling or heating
efficiency, please clean it once every two weeks.
With this new technology, the display area will appear EC (if
applicable) and the LED indication lamps continue flashing
when the outdoor unit detects refrigerant leakage.
Louver Angle Memory Function (optional):
For some models, the machine is specially designed with
louver angle memory function. Power failure during
operation or pressing the ON/OFF button on the remote
controller will stop the unit completely. When the
power restores or pressing the ON/OFF button on the
remote controller again, the unit restarts automatically with
the previous open angle of the horizontal louver by the
memory function. So we strongly recommend that the
open angle of the horizontal louver should not be set
too small,in case the condensed water forms and drops
from the horizontal louver. Press the Manual control button
and the open angle of the horizontal louver will be restored
to the standard angle.
Disconnect the unit from the power and then connect the
unit to the power again. Push the ON/OFF button on the
remote controller to restart operation.
Refrigerant Leakage Detection(optional):
