Looking for some help with valve settings before I remove my salt cell for first time cleaning. I only have three valves and one pump in my set-up. Two of then are actuated and one is manual (photo with arrow). The first photo shows the actuated valve settings for the spa only to circulate and the jets to work. Third photo shows the "default" position of the valves with water pumped into the spa for the spillway to empty into the pool and suction into the skimmer. Looks like top valve controls flow out to the pool/spa from the pump and the lower valve controls flow from pool/spa via the drains. The third (manual) valve stays in that full open position. To avoid a geyser when I remove the lid on the pump, I turn it 90 degrees counterclockwise so the off tab is pointing to the pipe to the right of the valve. It's also connected to a pipe that goes straight down into the ground which I have no idea what that might be connected to. Last photo shows the location of my salt generator. I'm thinking that the top valve needs to have the off tab pointing in the direction of the salt cell to block any water flow to it while I remove it for cleaning. Just not sure how to turn the handle to that position or if I would be doing the right thing. It has a toggle switch on the back which has an off position. Does that disengage it so I can move it manually? The Pentair instructions aren't helpful.

Just turn the pump off and remove the cell - unless your pool is to the right of the wall next to the last pic putting the water higher than the filter is. If not then no worries with breaking the connection.
 
Thanks for the reply. Should have included a key point - pool/spa are at a higher level than the pool equipment (see attached photo). It's hard to get the right perspective but the concrete base on which the pump sits is about 3-1/2 feet below water level in the attached spa.

Only clean the cell if it needs it. If you have TFP water with a slightly negative CSI, you'll probably never have to clean the cell during its lifetime. If you truly need a cleaning follow this guide:


Use acid only as a last resort.
 
You can also do a visual inspection of the blades. Takes less than five minutes.

My IntelliChlor cell has been working almost non-stop for the last four years. I have zero buildup on my plates. I expect to never clean my cell.
