How to Replace Stage-4 Membrane:

There are several membranes (2 to 4 depending on model) provided with your system. Please

insert the membrane into each housing one-by-one to prevent mis-connecting the tubing.

1. Locate the Membrane housings on the system. See Fig 8

2. The number of housing matches with the number of membranes provided. Each housing is

labeled as: “MEM-1”, “MEM-2”, “MEM-3”, “MEM-4” depending on your Ro model.

3. Start with “MEM-1” housing: Insert the membrane into one housing at a time. Finish up the

connection before going onto the next housing. This will prevent confusing the tubing order.

Insert membrane: See Fig.8A Remove the tubing from the membrane housing cap. Open the

cap. Insert membrane all the way into the housing tightly with the correct side going in first as

shown below. The end with 2 black-rings goes in first.

4. Close the housing cap. Re-connect the tubing to cap as before. Make sure to connect each

color coded tubing to its corresponding (matching) housing. This is important for proper filtra-

tion.

5. Proceed to insert the other membranes in the same manner.

Note: Make sure the membrane’s end with 2 black-rings goes into housing first!
