What should be done?
8. 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.
9.
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.
10.
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.
11. 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.
