Nanopure Life Science (UV/UF)
Note To prevent leaking, push the tubing into the atmospheric drain
connection until it bottoms out.
When the Nanopure flushes its membrane, the water used is sent to drain
through this connection. To install:
1. Locate the drain water tubing. This is the 1/4" (0.64 cm) O.D. tubing
that is approximately 6 ft. (1.9 m.) long. The atmospheric drain fitting
is located on the lower left side of the Nanopure.
2. Route the other end of the drain water tubing to an atmospherically
vented drain and make a connection. Ensure there are no kinks in the
tubing and that it proceeds in a downward plane. Proceed to "Initial
Operation."
To make tubing connections:
1. Make sure the tubing is cut
off reasonably square and
that no plastic burrs or
ridges are present.
2. *Mark from end of tube the
length of insertion.

3. Wet the tube end with water
and insert tube straight into
fitting until it bottoms out
on interior shoulder and
insertion mark is no longer
visible.
4. To remove tubing, push
collet toward fitting body
and pull on tubing. To reuse
fitting, begin assembly at
Step 1.
