Use the system with the following temperatures for safe
and effective operation. The max operation temperatures
for the air conditioner is listed. (Cooling/Heating)
3. AIR CONDITIONER OPERATIONS AND
PERFORMANCE
1
If the air conditioner is used outside the above conditions, it
may cause the unit to function abnormally.
Relative room humidity should be less than 80%. If the air
conditioner is over 80, the surface of the air conditioner may
become moist . Please set the vertical air flow louver to its
maximum angle (vertically to the floor), and to HIGH speed.
Optimum performance will be only be achieved when within
these operating temperature ranges.

4. HINTS FOR ECONOMICAL OPERATION
The following should be adhered to in order to ensure fully optimal
performance. (Refer to corresponding chapters for details)
5. ADJUSTING AIR FLOW DIRECTION
Auto-Swing
Press the SWING button, and the louver will swing up and down
automatically.
When Cooling:
Adjust the louver downwards (horizontally)
(Refer to Fig.5-2).
When Heating:
Adjust the louver vertically
(Refer to Fig.5-3).
Three-Minute Protection Fea-
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 the power is restored
To restart operation, push the ON/OFF button on the
remote controller.
Lightning or wireless telephones operating nearby may
cause the unit to malfunction.
Disconnect the unit from the power, and then reconnect the unit
to the power again. Push the ON/OFF button on the remote
controller to restart operation.
Adjust the air flow direction properly to avoid direct draft toward
your body.
Adjust the room temperature properly to get a comfortable
environment and to also avoid supercooling and superheating.
During 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 when necessary.
Set the timer for the desired operating time.
Never put obstructions near the air outlet or the air inlet. Else it
will cause lowered efficiency, or even a sudden stop.
If you don't plan to use the unit for a long time, disconnect the
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.
Disconnect the power to save energy. 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,
therefore it’s important to clean it once every two weeks.
Manual Swing
Press the Air Direction button and the louver can be fixed at
a desired angle.The louver swings upward or downward to a
certain angle for each press.

With this new technology, the display area will show EC (if
applicable), and the LED indication lamps will continue flashing
when the outdoor unit detects refrigerant leakage.
Louver Angle Memory Function (optional):
For some models, the machine is specially designed with a
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 by
pressing the ON/OFF button on the remote controller again, the
unit restarts automatically with the previous open angle of the
horizontal louver set by the memory function. Hence, we
strongly recommend that the open angle of the horizontal
louver should not be set to be too small, in case condensed
water forms and drops from the horizontal louver. By pressing
the manual control button, the open angle of the horizontal
louver will be restored to the standard angle.
Refrigerant Leakage Detection (optional):
