UV Pentair 18W

Scottydo · Feb 7, 2022

Anyone installed a Pentair 18W UV? I have read the instructions and installed just about everything, however the instructions say (in multiple spots with underline and red and !!!) there should be a 4" spacer between the bulb connection and the next nut on the top, which we do not have. The instructions say this MUST BE INSTALLED in multiple spots yet when I called their (pentair) customer service they seem to indicate that it was optional. I also just spoke with BRS and they sent me a letter talking about a change to the setup but it is for a totally different piece. Anyone smarter than me know if this is accurate or if they just did not want to deal with it? Thanks!!!

I've not seen a spacer, but you do have to leave a 4" space between the bulb and the nut so that the bulb is positioned correctly.

i just measured the gap with a tape measure and it's been running fine for 10 months.
