Does anybody have any experience with the Jandy DEV60? I just finished cleaning the filter grids and am trying to reinstall the tank clamp. The manual says to tighten the clamp to within 1/16th of an inch...which it was before I disassembled. I got it to about an 1" and it started screeching with every turn of the wrench. I'm afraid I will damage the tank or clamp if I continue. I cleaned the clamp and the tank before I began installing and made sure it was seated correctly. This is my first cleaning with the new Jandy, but disassembled and reassembled my old Pentair +/- 30 times without any issue. even thinking about lubing the clamp. Any suggestions would be appreciated.
