Can someone please help me answer some questions.
I ordered a set Sungrabber (FAFCO) Solar collector 2 x 2' by 12', these are being mounted on the roof facing south. I also ordered a Aqua Solar GL-235 controller. In the meantime i added a separate filter pump 1/2 HP 2500 GPH pump that will be controlled by the GL-235 I have included some pictures. I also started the hard plumb, I also added a sprinkler to cool down the water on hot hot summer days.
I have attached a picture of the setup recommended; according to the sungrabber manual altered the diagram to fit what i think would work for myself.
Still wasn't convinced I reached out to Fafco directly and they supplied me a different diagram setup
Can someone please assist
1. Which diagram/setup should i use?
2. I like to install a pressure gauge being the pump does not have one, and i don't want to blow this solar panels off my roof, where in the setup would i install it to measure pressure.
Please help me
