I know nothing about these things, just bought this used pool and filtering system. On the lid assembly where you push the handle down to move it around to the different positions, the labels are faded out, all except the backwash one. Have searched unsuccessfully for a manual. Can anyone tell me what the positions are, say clockwise from the backwash setting, and what each one does? Or give me a link to a manual?
I will be forever grateful for any help!
