Steve, the fan moves a lot of air around the corner of the room, which to me is more than enough. I didn't buy this with any instructions about installing a 19" fan 12 inches from the front of the chiller. I shouldn't have to use ANY fan to cool it, as far as I'm concerned.
John (J&L) mentioned they had this once with someone who had too ittle water flow thru the unit, but that doesn't seem to be my problem. I'll meausre the flow tonight.

Brad,
I'm using the original fuse, probably 10A. I'll take a look later and let you know if its anything other. For water circulation I'm running a Mag12. I wonder if the fan is smaller in the newer units since you noted earlier that yours was fairly quiet. I'll see if I can read the numbers on the fan as well.

I'm only running a MAG 7, so I wonder if that's the reason??

to little water flow or to much?.. hmm that could be, kinda makes sence in a round about way.. I'll see what I can dig up in my refrigeration book on that..

what are you using for a pump? after checking my application I am thinking I am only putting 300gph through mine max

Steve

John said a min of 400 was needed.

hmm so mine shouldent be working then :confused:

Steve

OK, what pump is everyone running on their PCI chillers? It looks like mine isn't pumping the minimum required. Only about 135gph right now. I'm going to see what I can do about that.

mag 7

pumpin at only 2' of head

How much plumbing have you got in the loop? I have about 20 ft. which includes some barb fittings. I'm going to replumb with all 3/4" when I get back from camping.

Hmmm.

3/4" ID tubing, going from the mag 7 in the sump to the chiller (about 2' run) then from the chiller to the UV unit (16-18" run) and then from the UV to the sump (2.5' run).

I really didnt think my last post thru very well :)

I should measure the output of that.
