chart to save time and unnecessary expenses.
Problem
The air
conditioner does
not work at all.
I cannot change
the temperature.
Cool air does not
come out of the
air conditioner.
• Check the power status, then operate the air
conditioner again.
• Switch on the circuit breaker, plug in the
power cord, then operate the air conditioner
again.
• Make sure that the isolator is turned on.
• Check whether the Timed off function is
running. Operate the air conditioner again by
pressing the Power button.
• Check whether the Fan or Fast mode is
running. In these modes, the air conditioner
controls the set temperature automatically,
and you cannot change the set temperature.
• Check whether the set temperature is higher
in the Cool mode mode than the current
temperature. Press the Temperature button
on the remote control to change the set
temperature.
• Check whether the air filter is blocked with
dirt. If the air filter is blocked, the cooling
performance may decrease. Remove dirt
regularly.

or installed near obstacles. Remove the
coverings and obstacles.
