## Questions & Answers

**Q: Looking at "b 4.5".  current one is 4", to 3" pipes.  other reviews/questions + product title indicate this is 4".  is it 4" or 4.5"?**
A: Always think pipe dimensions (the ID of the pipe) when dealing with pipe.  The Rn2's top and bottom connections are 4.5" OD nominal which translates to 4" pipe. You use a 4x3 Flex Coupling with the Rn2 and 3" PVC pipe.  The PVC vent pipe is usually 3" which translates to 3.5" OD x 3" ID Schedule 40 PVC.

**Q: how many square feet of basement with a sump pump will this service**
A: Basing fan selection on square footage of a basement is not exact since air flows will vary based on many factors. But in most cases the RN2 should be fine up to about 2500 sq/ft. This is a 4" fan so using 4" pipe will give the best results.

**Q: Can this fan be on a switch and turned off when we are away?**
A: As a radon professional, most of the fan failures I've seen in 20 years are when fans have been off for a period.  Soil moisture coming out of the pipe and condensing on the metal parts (bearings) can ruin them.  They seem to be good for at least 15 years running continuously when properly installed.  If you have to shut it off, remove and store the fan and replace the space left by the fan with solid pipe so you don't have any other moisture issues.  Shut off switches located near these fans is an NEC safety code requirement.  Radon levels go right back up a few hours after turning a fan off and the converse is true.

**Q: The rn-1 is advertised on amazon as 90cfm. why does the sticker on my rn-1 say 130 cfm ?**
A: I don’t know. I have a rn-2 fan which is 130 cfm.

### ⭐⭐⭐⭐⭐ Perfect replacement for old Fantech HP190 radon fan
*by D***R on December 10, 2018*

I had an old Fantech HP190 radon fan in my attic that was getting very loud. I replaced it with the new Rn2 model and am quite happy. The Rn2 seems well built. The Rn2 is slightly shorter and has different size connectors than the HP 190, but I had no problem finding some flexible PVC couplings that worked perfectly at the local hardware store (I used a 4" x 4" on bottom and 4" x 3" on top). The bigger problem was that whoever originally installed the fan used 3" PVC pipe with 4" adapters cemented in the ends. That gave the fan a little more stability, but made it impossible to slide the coupler up the pipe to remove/replace the fan. I ended up having to cut off the top 4" PVC adapter along with some 3" pipe back far enough that would allow me to add a standard 3" PVC coupler and 3" PVC pipe to get it to the right height so that the fan could easily slip in, but still allow the coupler to slide up the pipe for installation/removal. Wiring up the new fan was no problem, I just used the plug from the old fan. The new fan is working great and quiet. Fantech included a tootsie pop and an "Our fans suck" stick in the box for fun.
