5.Troubleshooting Guide
1.The input voltage must be 10% tolerance of the rated Voltage.
If it is not the case, the air-conditioner will probably not work normally.
2.Check the connecting cord between indoor unit and outdoor unit to see if it is properly
connected. The connecting must be done according to the wiring diagram, please also
notice that even different models may have the connecting cord of the same specification.
Please check if the marks at the connecting terminal and the marks on the cord can match,
otherwise, the air-conditioner will not work normally.
3.If the following phenomena are found, the problem is not from the air-conditioner itself.
Problems Causes
The motor is heard operating but
the air-conditioner dose not work
when the indoor unit is powered on
The compressor stops running but
the indoor fan motor keeps working
when it is at cooling mode with the
indoor temperature higher than set
temperature.
The compressor works discontinuously
at dehumidifying mode.
Since the air-conditioner is powered on, it will
come to working condition as long as you press
the ON/OFF button of the remote control and the
signal is well received.
If you turn off the air-conditioner and restart it
immediately, it will return to normal in 3 minutes,
after that, the air-conditioner will automatically
adjust the indoor fan speed to what you set.
The air-conditioner will automatically control
the working of the compressor according to
the inside temperature
The air-conditioner dose not work
while the LED display is on.
The TIMER is set with the air-conditioner,it will
be in hold on condition. If the TIMER setting is
cancelled, the air-conditioner will return to
normal working condition.
The compressor stops internally or the fan motor
slows down to prevent the indoor heat exchanger
from being frozen.
The compressor works discontinuously
at cooling and dehumidifying mode,
and the indoor fan motor slows down.
