As long as the filter press has not set idle more than 3 hrs, there is no issue. If it has set longer, but never over 6 hrs, just put the discharge hose in the mix tank, add a little more DE and let it run until it looks crystal clear, then shut the pump off, move the discharge hose to the canner or a barrel and pump. Before leaving for the night, open the press, clean the plates and install new papers.
Did you read the Filter Press info at Proctor UVM? they have a good paper on there, print it out and save in the sugarhouse as a guide. You will only need it the first few uses and after that it will all be second nature.
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.
