RO Membrane Installation

24 LPH Units (2 Membranes)

1. Remove the RO membranes from their packaging. Note the location of the FEED, PRODUCT,
and REJECT connections on the membrane.
See Figure 3-13. 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
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 3-13. 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 3-13.
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 3-13.
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.
9. The door can remain open until the unit has been operating and you have checked for possible
water leaks at the membrane connections.
