Can't find any info on this and tried to do it with putting a DSW next to it and it's didn't auto eject, tried using RP2 filter on it's side and bottom and it just pull out the sand not the glass. I config the filter to pull out glass and it's just sits there when it's get it pulse so how in the world do I automate it?? There are two button too and can't seem to figure out what they do, one is a blue lighting bolt while the other is a arrow with a orange background to it. So pleas can someone explain to me how to use these machines properly?
