Step 6: Installing the Reverse Osmosis Membrane
6.1 Open the membrane
housing screw cap.
First, you will need
to disconnect the
white 1 / 4” tubing
from the Inlet quick-
fitting on the
membrane housing cap (refer to How to Use Quick-Fitting section), and then unscrew (counter-
clockwise) the cap. A thick rubber band can be slipped on the housing body for a better grip.
6.2 The RO membrane is preserved in a sealed bag. Follow the flow direction sign on the
membrane, and firmly insert the membrane
into the housing. The smaller end with two
black O-rings should be inserted first until the
back end is even with the housing opening.
6.3 Before twisting the housing cap back on,
check to make sure the O-ring is placed
securely on the membrane housing (cap
does NOT have O-ring). Hand tighten and
then using a small plastic housing wrench
tighten 1 /4 – 1 /2 of a turn, be careful not over
tighten. DO NOT reconnect the tubing to inlet
on cap at this point (This connection is made in the system start up step).
Step 7: Tubing Hook up
7.1 See the Sample Installation and RTW5 TOP VIEW, note connection points A-B, C-D, E-F,
and G-H.
7.2 Facing the font of the unit, with the brand logo, the 1st stage pre-filter is located on the right
hand side. Connect the RED tubing Feed Water Adapter (AFW) (point A) to the elbow fitting
(point B).
