The RO/DI is cranking out 0TDS water at the rate of about 150GPH, but I'm hearing new noises emanating from the boost pump. It's an older pump and likely due to be rebuilt/replaced. I'm also concerned that it might be out-drawing the 1/4" feed coming from the saddle valve.
I decided to order a new Aquatronic 8800 boost pump, pressure switch and solenoid that will cut the flow of water to the system when the pump is de-energized. I'm also adding a second saddle valve which will be T'd into the supply side of the RO/DI.
A float at the top of the RO storage tank will turn off the pump and cut the water supply to the RO/DI. Once I determine the evaporation rates and fill times required, I'll use the Apex to manage the pump on/off days and run times of the pump as a fail-safe.
