LG Ductless Split Cassette Drain

[Matthew Haberland]

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.

LMCN078HV-NG. I did some more searching and I do believe I found the proper way to route all the drains into one larger PVC.

Cassettes have a drain pump so the riser isn't a problem just be sure to have a little fall in the main drain line they don't want anymore pressure the pump has to fight.
