Picture 8 - Discharge of oil and dirt
IMPORTANT NOTE
1) The low-pressure manometer (Picture
4
, Pos. 16) – shows the pressure in the circuit being
flushed. It does not show any overpressure in the distillation chamber.
2) Oil and sludge can also be discharged from the distillation chamber after the flushed circuit is
disconnected. However, you must connect the inlet and outlet with a single hose (see Picture
10) and follow procedure 8.4,.
3) The procedures and pressures in this manual assume a workplace ambient temperature of
about 16°C – 24°C.

If the pressure read on the LP manometer after the flushing procedure is higher than the vapor
pressure reported here above (at the specific work temperature), there is some liquid
SOLSTICE
®
PF-C in the circuit.
NOTE
The
temperature of the flushed circuit can drop below ambient temperature due to the
cooling effect caused by the evaporation of SOLSTICE
®
PF-C, especially during the
flushing of complicated circuits with siphons.
5) For the recovery of the flushing solvent at low ambient temperature (or due to the under-
cooling of flushing solvent described above) it is necessary to repeat several times the
procedure at point 8.2.4 or to warm up the flushed circuit at a temperature of at least 20°C.
6) Ambient temperatures in excess of 40°C decrease the operative lifetime of EkoFlush unit.
