How to Change RO Housing and Membrane?
1. Turn off the feed water supply line valve to the RO system and the valve on the water tank.
2. Open the RO faucet to release the system pressure for safe maintenance.
3. Remove the blue safety clip, press down the collect, and carefully disconnect the tubing from the membrane housing.
4. Use the provided wrench to effortlessly remove the membrane housing cap.
5. Employ pliers to extract the used membrane, discard it, and gingerly insert the new one. Make sure the end with two small washers is inserted first; push until snugly seated in the housing.
6. Replace and securely tighten the membrane housing cap. Reattach the tubing and firmly set the blue safety clip back into place.
Note: If the housing cap doesn't align easily, gently twist the RO membrane for proper seating at the pure water outlet.
