RO MEMBRANE REPLACEMENT
1. Turn off the water supply to the RO system, close the ball valve on the tank, and open the faucet to relieve
pressure in the system.
2. Remove the black tubing from the membrane feed push fitting by depressing the collar
on the fitting with your thumb and pulling the tubing from the push fitting (See “Working
With Push Fittings on Page 10.).
3. Lift the membrane housing from the retention clips.
4. Unscrew the membrane housing lid. This may require two people.
5. Use a pair of pliers to grasp the membrane stem and pull the membrane from the housing.
6. Remove the black housing O-ring. Wash the empty housing with soapy water. Rinse thoroughly with hot, clean
water.
7. Insert new membrane into the housing, with the double O-ring end first. The tube must fit into the recess at the
bottom of the membrane housing. When the membrane is aligned with the hole, firmly push the membrane
into the hole until it bottoms out.
8. Place the black housing O -ring on the housing rim and carefully screw the lid back on to the base.
9. Reconnect the black tubing to the membrane feed push fitting and insert the membrane housing back into the
retention clips.
10. Close the faucet, open the ball valve on the tank, and turn the water supply back on.
11. Allow the tank to fill, then open the faucet and allow it to drain completely. Repeat this two more times. This will
help to ensure that you have flushed all of the preservatives from the new membrane.
12. Check the system for leaks before allowing it to run unattended.
NOTE:
If you are replacing the membrane with one of a different flow rate (i.e. Replacing a 90 GPD membrane
with a 200 GPD membrane) you must replace the flow restrictor with the appropriate one for the flow rate
of the new membrane.
