Note: For a pre- or post-filter you only need to connect its inlet and outlet. For the membrane
you have to connect the third outlet – to the waste water line. This outlet is located off the
center of the membrane housing. Elbow check valve fitting (with the arrow) has to be con-
nected to the central (permeate) outlet of the membrane housing.
close the cover, reconnect the external tubes and place the unit back in its place
■
After you finished changing filters or the membrane follow the "initial washing" procedure as
described above. With initial operation, check for leaks. If a leak is observed, verify that the
tube or branch pipe of the filter/membrane housing is pushed into the quick fitting far enough
to seal the tube against the O-ring and that the tubing was cut at 90
