Finally got a chance, though only about 30 minutes before dark, to vacuum the pool. Since we had a storm recently and I had the yard mowed, the bottom was pretty dirty. I set it up to vacuum to waste, or I thought I did, but it didn't seem to work, and I was just stirring the dirt up. I put it back on filter and it worked fine.
Two questions came from this. I can't seem to find a top down picture of the multi-port valve on the S244T that I have, even the manual doesn't show it. The writing on the top ring is worn down so I'm not sure what all the positons are. Does anyone have one?
Also, later last night while looking for a picture, I read something about if you have an in-line chorinator, you need to shut it off prior to vacuuming. I didn't even know there was a valve on it (there is) so I didn't turn it off. Did I do any harm by not turning it off before I vacuumed the pool?
