Reverse Osmosis (RO) Membranes installed

So I was a little concerned with the placement of the RO membranes. It says in big letters, operating temps from 32f to 120f.  My engine room get hot.  So looked all over the boat to mount these tubes. I found a few places but it would mean running high pressure lines 20 feet or more and drilling holes in the bulkhead.  Something I wasn't too thrilled about.  A friend suggested I take a laser temperature tool and actually measure the heat before I place them in the back of the boat.

This morning I ran the engines at 1000rpms for 1.5 hours. Engine room was heated up nicely. I took a laser temp tool with me. The front of the ER was cooler (70f) that the rear (92).

When I shut everything down and let it sit for about 45 minutes, I took some more readings. The front had warmed up to 82f and the rear around 100f. I am still a little concerned about the temps during the summer, but I will keep an eye on it. I just have to learn to duck when entering the ER. Time to read ( they sent me a thumb drive with all the instructions. I took it down and had it printed) and then off to the plumbing
