6. AIR CONDITIONER OPERATIONS AND
PERFORMANCE
Use the system in the following temperature for safe and
effective operation.The Max operation temperature for
the air conditioner.(CoolinglHeating)

if air conditioner is used outside the above conditions, the
unit may function abnormally.
Room relative humidity should be less than 80%. If the
relative humidity exceeds 80%, the surface of the air
conditioner may condense water. Please set the vertical air
flow louver to its maximum angle (vertical to the floor), and
set the speed to "HIGH".
Optimum performance is achieved within this operating
temperature range.
Three-minute protection feature
A protection feature prevents the air conditioner from activating
for approximately 3 minutes when it restarts immediately after
operation.
[] Power failure
[]
[]
A power failure during an operation will stop the unit completely.
® The OPERATION lamp on the indoor unit will flashing
when power is restored.
® To restart an operation, push the ON/OFF button on the
remote controller.
® Lightning or a mobile telephone operating nearby may
cause the unit to malfunction.
Disconnect the unit from its power source and then connect the
unit to the power source again. Push the ON/OFF button on the
remote controller to restart the operation.
Refrigerant Leakage Detection(optional):
With this new technology, the display area display 'EC' (if
applicable) and the LED indication lamps continue to flash
when the outdoor unit detects refrigerant leakage.
Louver Angle Memory Function(optional):
For some models, the machine is special designed with the
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 retained by the memory function.So we strongly recom-
mend that you do not set the open angle of the horizontal
louver too low 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 return to the
standard angle.
7. HINTS FOR ECONOMICAL OPERATION
The following should be reviewed to ensure an economical operation. (Refer
to corresponding chapter put a space between chapter and for for details)
[] Adjust the air flow direction properly to avoid wind flowing
toward your body.

Adjust the room temperature properly to avoid over cooling
and over heating.
When cooling, close the curtains to avoid direct sunlight.
To keep cool or warm air in the room, refrain from opening
doors or windows unnecessarily.
Set the timer for the desired operating time.
Never put obstructions near the air outlet or the air inlet. Doing
so will cause lower efficiency, even a sudden stop.
if you don't plan to use the unit for a long time, please discon-
nect power and remove the batteries from the remote control-
ler. When the power switch is connected, some energy will be
consumed, even if the air conditioner isn't in operation. Also,
switch the power on 12 hours before you restart the unit to
ensure a smooth operation.
A clogged air filter will reduce cooling or heating efficiency, so
clean it once every two weeks.
8. ADJUSTING AIR FLOW DIRECTION
Auto-swing
Press the SWING button, the louver will swing up and down
automatically.
Manual Swing
Press the Air Direction button,the louver can be fixed at a desir-
ed angle.The louver swings (upward or downward ) to a certain
angle for each press.
Fig. 5-1
When cooling
Adjust the louver downwards. (horizontally)(Refer to Fig.5-2).
When heating
Adjust the louver vertically(Refer to Fig.5-3).
