1. The Foremost Inspecting Items
⑴
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.
⑵
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.

air-conditioner itself.

the ON/OFF button of the remote control and
the signal is well received.

the indoor fan motor keeps working
when it is at cooling mode with the
indoor temperature higher than set

automatically adjust the indoor fan speed to
what you set.
