Method of transmission:
• Point the remote controller at the air
conditioner and press the button on the
controller. The instruction signal will
be transmitted to the air conditioner.
• Upon receiving the signal from the
remote controller, the air conditioner
unit will utter a "dee-" sound for
acknowledgment.
Points of attention in using the remote
controller:
• Do not place the remote control near
high temperatures, such as heaters,
radiators or electric blankets or pillows.
• Do not place the remote control in direct
sunlight or strong light.
• Avoid accidental dropping of the remote
control, as this could cause damage to
the remote control.
• Do not place any blocking objects
between the air conditioner and the
control unit.
• Do not splash the remote control with
water or other liquids.
• Do not place heavy objects on the
controller.
• If the remote control does not work,
replace the batteries and try again.

REPLACEMENT OF BATTERIES

When the signal is transmitted but the air
conditioner does not give a confirmation
signal, it means that the batteries are dead
and need to be replaced.
• Remove the battery cover and take out
the used batteries by sliding the cover
in the direction of the arrow.
• Replace the batteries with new ones,
paying attention to the "+" and "-" poles.
• Close the rear cover.
Note: the timer is set based on the current
time. Therefore, you must set the current
time correctly.

MAINTENANCE

(See picture 09 (N) on page 8).
WATER DRAINAGE
The air conditioner evaporates condensed
water and discharges the moisture through
the hot air outlet.
But in some cases it is possible that the unit
is not to condensate water evaporation,
then the internal water tank is full, the
FULL lamp will illuminate and unit will
stop running.
Follow the steps to drain water (see picture
09 (O) on page 8):
• Unplug the air conditioner, disconnect
the exhaust hose from the back, and
move the conditioner to suitable drain
location or outdoors.
• Remove the base stopper from the base
water outlet to drain water.
• Once the internal water tank is drain,
reinstall the base stopper, make sure it
is on securely.
• Place the air conditioner in the desired
location, reconnect the exhaust hose,
and plug in the air conditioner. The unit
will operate normally.
To avoid accidents caused by
electric shock, make sure that
no power is supplied to the unit
before starting maintenance or
repair.

accumulation of a large amount of dust,
the volume of the air flow will be reduced.
Clean the filter once every two weeks.
