Troubleshooting Guide

1. The Foremost Inspecting Items

⑴The input voltage must be within +10% tolerance of the rated Voltage. If it

is not the case, the air-conditioner will probably not work normally.

⑵Check 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.

⑶If the following phenomena are found, the problem is not from the

air-conditioner itself.
