So my Pentair IC40 lasted 5 yrs. Now dead (power at transformer, no lights, no power at unit). My pool is 18k, inground, pebble finish. My Pentair Mastertemp 400 just died due to leaking water exchange manifold (rusted and corroded tub). When pool company came out to replace it with a Jandy JXI 400 (I’m growing tired of my Pentair equipment dying), I had them test the IC40. Confirmed dead. They suggested replacing it with an Ichlor 30, as that’s “all I need” for my pool size and it’s a direct screw on replacement. About $850 with the service call. With the advantage of this forum, found an Ichlor 30 online for $540 with free shipping. My question, is it as easy as it sounds to just “plug and play“ the Ichlor30 for the IC40? Thank you!
