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.
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

.

off for a sufficiant periods of time.
