6.1 Open the membrane housing cap. A thick rubber band can be slipped on the housing body
for better grip.
6.2 Find the inner end with 4 O-rings, cut open the end of sealed bag and use it to hold RO
membrane to avoid contamination, and firmly insert the membrane into the housing until
the outer end with only 2 O-rings is completely inside the housing. See Figure above.
6.3 Before twisting the housing cap back on, check that the O-ring is evenly snagged on the
membrane housing (cap does NOT have O-ring). Hang tight and tighten up for about 1/4
– 1/2 turns using a small plastic housing wrench, but do not over tighten. DO NOT
reconnect the tubing to inlet on cap at this point (will do it in system start up).
Step 7: Tubing Hook Up (optional sub-steps are marked with * )
7.1 Facing the iSpring logo up front, locate the pre-filter 1
st
stage on the right hand side.
Connect the 3/8” tubing between Feed Water Adapter (AFW) and point A.
7.2 Connect the Flow Restrictor (point C) , which is a 3” long cylinder with a FLOW sign
laying beside the membrane housing, to the black Drain Saddle with 1/4” tubing.
7.3 Connect the Post Carbon Filter FT15 5
th
stage (point B) to the RO faucet with 1/4” tubing.
* If you have a RO storage tank, replace the elbow fitting at point D with a Tee fitting, reconnect
the tubing from the check valve to one T, and connect the other T with tank shut-off valve.
