What should be done?
7. Dripping water may generate on the surface of the indoor unit when cooling in a high
relatively 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 air conditioner draws in heat from the outdoor unit and releases it via the indoor unit
during heating operation. When the outdoor temperature falls, heat drawn in by the air
conditioner decreases accordingly. At the same time, heat loading of the air conditioner
increases due to larger difference between indoor and outdoor temperature. 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 stop the unit completely.
For the unit without 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 controller. For the unit with 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 special designed with Auto-restart function for the open
angle of the horizontal louver.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 all the
previous settings including the open angle of the horizontal louver by the memory function.
So we strongly suggest 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
AUTO/COOL button under the front panel and the open angle of the horizontal louver will be
restored to the standard angle when the condensed water forms on the horizontal louver.
10. Lightning or a car wireless telephone operating nearby may cause the unit to malfunction.
Disconnect the unit with power and then re-connect the unit with power again. Push the
ON/OFF button on the remote controller to restart operation.
11.
The protection of outdoor low temperature(on some models)
The protection of outdoor low temperature can be activated only in the HEATING mode.
The unit will stop operating and display "P3" on the LCD window of the indoor unit when the
outdoor temperature is or lower than 5 F(-15 C) for one hour, but the indoor unit in this situation
can still receive the signal from the remote controller.The unit will restart automatically with all the
previous settings preserved by the memory function when the outdoor temperature is or higher
than 11 F(-12 C) for 10 minutes and the compressor stop operating for more than one hour, or
when the outdoor temperature is or higher than 41 F(5 C) for 10 minutes.
