11.5.3 Water Separator/Extraction Tank

Dispose of the process water according to the regulations in your country.
You must clean the water separator and extraction tank routinely (and always after the distillation system
has boiled over). The unit does this automatically with a fixed maintenance program P54 or as an
integrated part of the so-called multi-maintenance program P49.
Start one of the maintenance programs listed above weekly.
You can run another program at the same time as the maintenance program.
Sequence of the maintenance program:
Step 1: Draining the water phase from the water separator into the tank (7).
Step 2: Emptying the water separator into the distillation system (6) with the solvent pump.
Step 3: Rinsing the water separator with solvent from the clean tank (5).
Step 4: Emptying the water separator into the distillation system (6) with the solvent pump.
Step 5: Draining the water phase from the extraction tank into the tank (7).
Step 6: Emptying the extraction tank into the distillation system (13) with the solvent pump.
Step 7: Rinsing the extraction tank with solvent from the clean tank (11).
Step 8: See step 6
Step 9: Produce the recipient tank in the extraction tank.
Step 10: Bring recipient tank to defined level.
After the maintenance has completed, the horn sounds and the program ends. The cycle counter is reset
to 0.
General function at the end of a cleaning cycle:
The water phases from the safety separator and extraction tank are drained into the process water tank
when the loading door is opened.
