1. Remove the RO membranes from their packaging. Note the location of
the FEED, PRODUCT, and REJECT connections on the membrane.
See Figure 3-9b. The correct orientation for the installed membrane
will be vertical with the Feed connection on the bottom.
2. Open the left side door on the Thermo Scientific TII.
3. Locate the four unconnected tubes (three with elbows, one without)
labeled FEED 1, PRODUCT, PRODUCT and REJECT 2. Refer to
“Push-to-Connect Fitting Tubing Install” in this section, and mark
FEED 1 tubing 3/4” (1.9 cm) from end.
4. Find the tube with the elbow labeled FEED 2 and REJECT 1
packaged with the unit and mark FEED 2 end of the tube 3/4” (1.9
cm) from end.
5. Make FEED 2 (A) connection by first wetting the tube with water and
pushing it firmly into the membrane connector. See Figure 3-9b. Using
the Velcro® strap, secure the membrane into the leftmost position
against the chassis walls.
6. Make the FEED 1 (B) connection by first wetting the tube end and
push firmly into the membrane connector. Using the Velcro® strap
secure the membrane into the right most position against the bracket.
See Figure 3-9b.
7. Make the PRODUCT (C) and REJECT 1 (D) connections on right
most membrane by first wetting the tube stem of the elbow with water
and pushing it firmly into the connector. See Figure 3-9b.
8. Make the PRODUCT (E) and REJECT 2 (F) connections on left
most membrane by first wetting the tube stem of the elbow with water
and pushing it firmly into the connector.
