We learned the hard way, and after repeated over temperature and under pressure warnings we are in the process of dealing with these two issues.
Incoming water now passes through 50ft. of 3/8 cobber tube submerged in a tank where water is kept at about 60 degrees. The tank water is chilled by a water chiller and a small pump circulating the tank water.
This will keep the incoming water below 90 degrees.
Our 1hps cistern water pump serving our business isn't enough to keep pressure over minimum at the lowest point(about 38psi). - therefore we are in the process of adding a pressure booster - to the tune of $700.00 - to the line serving the Protomax. This pump adds another 30 - 35 psi and will eliminate the second problem.
We are looking forward to get our production re-started without any hiccups.

Thanks for sharing with the Community! How hot is the incoming water? This will help us understand the limits we should continue to test against. The measures you have taken will go a long way towards extending the life of the "wet end" portion of your pump, where all the water circulates and incoming water is pressurized to 30,000 psi. Thanks again for advancing solutions to the ProtoMAX community.

Follow up of the water temp/pressure problems we have on a tropical island:
We are now in full production - 5-8 hours a day - and taking advantage of the ease of operating the Protomax.
Our Australian booster pump works in conjunction with out regular "house" pump. It senses incoming water-flow an pressure and adds 30-40psi to the system keeping pressure at a steady 55-60psi.
As mentioned before our cooling system also works well. Our incoming water temp. often reached up to 96F and is now at a nice 83-84F. We have had it as low as 62F, but why spend more energy than necessary.

I should mention that our house and workshop is 100% fueled by wind and solar incl. 5 AC units and several freezers and refrigerators (and two electric cars)

Thanks for the feedback and great to see alternative energy in operation! We have a customer in Vista, CA that is having high water temp issues; I'll hook him up with this post. Thanks!
