What should be done?
7. Dripping water may
appear
on the surface of the indoor unit when cooling in a
relatively
high
humidity (relative humidity higher than 80%). Adjust the horizontal louver to
the maximum air outlet position and select HIGH fan speed.
8. Heating mode (For cooling and heating models only)
The
unit
draws in heat from the outdoor unit and releases it via the indoor unit
during
the
heating operation. When the outdoor temperature falls, heat drawn in by the
unit
decreases accordingly. At the same time, heat loading of the
unit
increases due to
larger difference
s
between
the
indoor and outdoor temperature
s
. If a comfortable
temperature can't be achieved by the air conditioner, we suggest you use a
supplementary heating device.
9. Auto-restart function
Power failure during operation will
completely
stop the uni
t
.
For unit
s
without
the
Auto-restart feature, when the power restores, the OPERATION indicator
on the indoor unit starts flashing. To restart the operation, push the ON/OFF button on the
remote control. For unit
s
with
the
Auto-restart feature, when the power restores, the unit
restarts automatically with all the previous settings preserved by the memory function.
For some models, the machine is designed with
an
Auto-restart function for the open
angle
of the horizontal louver.
Power failure during operation or pressing the ON/OFF button
on
the remote control will stop the unit completely.When the power restores or
when
pressing
the
ON/OFF button on the remote control again,
the unit restarts automatically with all the
previous settings
,
including the open angle of the horizontal louver
,
by the memory function.
This is why w
e strongly suggest that the open angle of the horizontal louver not be set too
small,
in case condensed water forms and drops from the horizontal louver.
If condensed
water does form,
Press the AUTO/COOL button under the front panel and the open angle of
the horizontal louver will be restored to the standard
angle
.
10. Lightning or
wireless phones
operating nearby
using the same frequency as the remote control
(around 38kHz)
may cause the
unit to malfunction
. If this happens, d
isconnect the power
from
the unit
and then reconn
ect it
. Push the ON/OFF button on the remote controller to restart
it.
OPERATION TIPS
