5. Connect an outlet tube leading to the sewage system (19 mm inner diameter). Since the OSCi functions
at atmospheric pressure, the outlet piping must always be positioned below the outlet connection on the
OSCi vessel 3, unless a pump (able to run dry) is installed (not provided).
6. Check that the filter in the first tower is of circular shape and that it can move freely up and down. Pour
clean water along the inner edge of the first tower until water flows out of the outlet connection or until
the water reaches the bottom of the sensor chamber (visible through the sight-glass). The oleophilic filter
(vessel 1) will start to float. Verify that the sensor arm (8) is in the upward position and rests on the edge
of the filter bag.
7. Check that there are no leaks at the connections between vessel 1, 2 and 3. If there is a leak, proceed to
Problem solving, fault 3.
8. Put the cover back on the first tower, tighten the clamping ring and close the compressor bodywork.
