Welcome to Just Answer! You can follow the drain line to the unit in the ceiling and notice a removeable panel just above the drain line... turn the power off and remove the panel. You should not have to remove more than 4 screws.
The access panel will have nothing else mounted on it... just a plain flat panel.Look that over and tell me what you find, We can go from there as long as you keep rating my assistance positigely... there is no time limit in that case.Phil
I think you might have the wrong equipment. This unit is an LG ductless system. The air handler hangs on the inside of the wall. The pressure lines and the condensate line go thru a 4" diameter hole. The condensate line can't be more than 5' long. Can you tell me if the condensate drain pan is accessible from the inside?
Thanks. I know the exactly what you are talking about. I was just reluctlant to start taking everything apart. I noticed that your a mechanical engineer..I'm a structural engineer, recently semi-retired. Thanks again.
