Turning old pump on for the first time

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?

Personally I would move the Jandy valve on the suction side from its 8 o'clock position to an 11 o'clock position to start.

I assume one side is main drain and the other skimmer. You want about 90% of your flow coming from the skimmers.
 
Have you started up the pool and run the pump yet?

You have 3 OFF toggles and 2 ON toggles. I suspect that timer is worn out and not reliable as to the toggles tripping it off.

When do you want to run your pump and for how long?
 
The initial advise was to run it the pump for 30 minutes after I put FC in. So I guess I want to run it from 10 pm for 30 minutes.

Just use the manual ON/OFF switch on the lower right to run the pump for 30 minutes.

Or adjust an ON toggle at 10 and an OFF toggle at 10:30 if you do this on a fixed schedule.

Have you read Determine Pump Run Time - Trouble Free Pool
 
Is this what you mean by an 11 o'clock position? It doesn't seem to allow me to turn to any other position.

Show us what range of motion you have on the valve to turn it.

That is odd. You definitely never want it at 6 as that closes off the pump suction entirely.

Remember, we are speaking about the OFF end. Not the handle.
 
As I have mentioned, it allows me to put the 'OFF' part of the valve only in 4, 6 or 8 o'clock. It can't go up to 11. Am I doing something wrong?

You are not doing anything wrong. The valve has physical stops the handle is hitting. If you remove the screw in the middle of the handle and pull the handle off you can see the stops. I would snap the stop off the handle so it can rotate 360 degrees.

He may want the suction valve fully closed when winterizing the pool or removing the pump. We don't know the level of the pool versus the equipment pad.

True -- but we know winterizing is out -- in Simi Valley CA the pool will remain open year around.

We don’t know what the intentions of the installer were with the valve. I suspect it was shutoff of the water instead of balancing the two suction lines. Being able to rotate the valve 369 degrees will let both be accomplished.
 
Fire it up. Be sure it primes and the pump basket is full of water and no air in a minute or two.

Then, check the skimmer for what its water flow looks like.
 
That there is some. Hopefully not a vortex. Does a leaf get pulled into the skimmer throat?
