I have installed plenty of ductless split systems, but I have not installed a cassette head before. The insturctions say you cannot pitch the drain up, but the diagrams that they have show differently. I need to run the drain roughly 12-15 inches up before I can start pitching the line due to where the drain is positioned. Anybody have any input on their installs in the past? The instruction manual is awfully vague.
