NOTE
1 If air conditioner is used outside the above
conditions, it may cause the unit to function
abnormally.
2 The phenomenon is normal that the surface of air
conditioning may condense water when the
relative larger humidity in room, please close the
door and window.
3 Optimum performance will be achieved within
these operating temperature range.
■Three-minute protection feature
A protection feature prevents the air conditioner from being
activated for approximately 3 minutes when it restarts
immediately after operation.
■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
remote controller.
• Lightning or a car wireless telephone operating nearby
may cause the unit to malfunction.
Disconnect the unit with the power and then connect the
unit with the power again. Push the ON/OFF button on the
remote controller to restart operation.
■Refrigerant Leakage Detection(optional):
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 special 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.
4. HINTS FOR ECONOMICAL OPERATION
The following should be noticed to ensure an
economical operation.
Adjust the air flow louver properly and avoid direct air
flow to room inhabitants.
Adjust the room temperature properly for a
comfortable environment. Avoid excessive heating or
cooling.
Prevent direct sunlight during cooling operation by
using curtains or blinds.
Ventilate often. Extended use requires special
attention to ventilation.
Keep doors and windows closed. If the doors and
windows remain open, air will flow out of your room
causing a decrease in the cooling or heating effect.
Never place objects near the air inlet or the air outlet
of the unit. It may cause deterioration in the effect or
stop the operation.
Set the timer .
If you don't plan to use the unit for a long time, please
take the batteries from the remote controller. When
the power is on, some energy will be consumed, even
if the air conditioner isn't in operation. So please
disconnect the power to save energy.
Keep the indoor unit and remote controller at least 1
m away from televisions, radios, stereos, and other
similar equipment. Failing to do so may cause static
or distorted pictures.
A dirty air filter will reduce cooling or heating
efficiency, please clean it once two weeks.
5. ADJUSTING AIR FLOW DIRECTION
While the unit is in operation, you can adjust the air
flow louver to change the flow direction and naturalize
the room temperature evenly. Thus you can enjoy it
more comfortably.
Adjust it up and down Fig 5-1
Adjust it up and down Fig 5-2
■Set the air flow direction.
Press the SWING button to adjust the louver to the desired
position and press this button again to maintain the louver
at this position.
■Adjust the air flow direction automatically.
Press the SWING button, the louver will swing
automatically. While this function is set, the swing fan of
indoor unit runs; otherwise, the swing fan doesn't run. The
swing scale of every side is 30°. When the air conditioner
isn't in operation (including when TIMER ON is set), the
SWING button will be invalid.
6. MAINTENANCE
CAUTION
Before you clean the air conditioner, be sure the power
supply is off.
Check if the wiring is not broken off or disconnected.
Use a dry cloth to wipe the indoor unit and remote
controller.
A wet cloth may be used to clean the indoor unit if it is very
dirty.
Never use a damp cloth on the remote controller.
Do not use a chemically-treted duster for wiping or leave
such material on the unit for long.
it may damage or fade the surface of the unit.
Do not use benzine, thinner, polishing powder, or similar
solvents for cleaning.
These may cause the plastic surface to crack or deform.
■Maintenance after a long stop period
(eg. at the beginning of the season)
Check and remove everything that might be blocking inlet
and outlet vents of indoor units and outdoor units.
Clean air filters and casings of indoor units.
Refer to "Cleaning the air filter" for details on how to
proceed and make sure to install cleaned air filters back in
the same position.
Turn on the power at least 12 hours before operating the
unit in order to ensure smoother operation. As soon as he
