17. Set the collection pan or bucket on a raised plat-
form/stool just below the drain line at each tank
inlet. Loosen the flange clamp on the drain cap,
and drain the lines at that area. Operate adjacent
valves to drain any fluid in nearby lines.
18. Set the collection pan or bucket on a raised plat-
form/stool just below manifold valve #4 (the recir-
culation line). Remove the flange clamp
connecting the recirculation line to the manifold,
and drain the line. Operate valves at the 1600 gal-
lon tank discharge line to introduce air and further
drain that line.
19. Close all valves and re-tighten the flange clamps
at the drains. Fill the tanks with several gallons of
clean water. Using waste water containers, repeat
step 9 through step 18.
20. Hitch the cart to a tractor, and lock-up the cart’s
electric clutch. See “Electric Clutch Lock-Up” on
page 32. Adjust the cart pump to setting 10.
21. Close all valves. Refill the tanks with about twice
as much water as for the previous flushing.
22. Fully open the hose valve on the gauge line. This
line is open through the manifold back to the
pump.
23. On the PFC2000, set the pump selector valve for
the 1600 gallon tank.
24. At the 1600 gallon tank, set the discharge selector
valve to the pump line.
25. Pull the cart with the tug until most (but not all) of
the water has been pumped from the tank.
26. On PFC2000, set the pump selector valve for the
400 gallon tank. At the 400 gallon tank, set the
outlet selector valve to the pump line.
27. Pull the cart with the tug until most (but not all) of
the water has been pumped from the tank.
28. Remove the bolts from the clutch.
