Leave the clamp on. The only thing to watch closely is the gasket in subsequent years. They will usually last 8-10 years, but buy some spares just in case. If you can feel the slightest nick on the seal, toss it and use a new one. I bought my spares thru Brewer's Hardware. In 2" they have both the silicone flat face and the standard with a raised portion in the center of the sealing surface. The only ones I've ever used have the raised portion. Never had a seal failure. I fill mine at 185-190F.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
