I installed the replacement last night and it was a straight drop in fit, except that the flow thru my plumbing is upside down. So I have to invert the SWG to have the controls right side up.
This means I also have to flip the flow sensor over. This was simple with the Intelliclor, just take it out, roll it 180 deg and put it back in. But this replacement has a groove and ridge that prevents you from doing that. I had to cut out a groove to flip it. Took all of 5 minutes.
As soon as I turned it on, it started working. My pool FC tested at 1 PPM and the water coming out of the return was 4 PPM. Incidentally, it also reported my salinity high at 4930. This because as the IC40 was failing, it was reporting low salt. So I added 80 lbs (I know, should have tested first!) But with it being springtime in OK, I'm sure rain washout will bring it down soon. If not, I'll get out the hose.
I'm happy so far. Now we'll see how long it lasts. Got 5 years out of the Intelliclor.
