Can't hold vacuum

igor_k on Wed May 21, 2008 9:21 PM User is offline

Folks, I bought a brand new VIOT VPD5 vacuum pump (5 CFM, micron rating of 15) and a digital vacuum gauge TP-605 (micron reading range of 15 - 12,000). I also had a gauge set made my CPS Pro-set. Between the three of them a steady vacuum can't be held. When connected directly to the pump via the yellow charging line, the digital gauge reads around 280 microns at best. As soon as I shut close the valve at the end of the charging line and shut off the vacuum pump the micron reading starts climbing. If the digital gauge is connected via the entire manifold it never goes lower than 900 microns. So I know there a leak somewhere. Could anyone please help me to troubleshoot this issue? Thanks.

I would add refrigerant, without starting use an electronic leak detector to help find it. Seems like you have most of the tools, leak detection equipment should be part of your tool box..Hope this helps..

Check out Electronic leak detector and I would add UV dye for future leak detection...
