We just moved into a house with a pool, and the pump appears to be off. I don't have any previous experience with pools, and I want to make sure I am turning the pump on the right way. I have read that the pump should never be on if it is not getting any water so I want to make I am not going to damage it. Attached are the pictures of my set up. Could you please advise what position the valve should be in when I am poring FC into the pool and how to set up the dial right?
