my panasonic air-conditioner was brought in Hong Kong 2010 and I cannot find the relevent manual on-line. Could you help me in the searching? The model no . is CS-V18KWA. And I also find the air-conditioner operationg at a very low humidity of 20-30% relatively humidity. I find it very dry. Is there anyway to optimize the humidity level when air-conditioner is on? Many Thanks. / Leo
