8.3 Troubleshooting Guide for -36K
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.

If the following phenomena are found, the problem is not from the
air-conditioner itself.

come to working condition as long as you press
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

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.

mode.
The air-conditioner will automatically control
the working of the compressor according to
the inside temperature
