How to Change RO Housing and Membrane?
1. Start by turning off both the feed water supply line valve to the RO system and the valve on the water tank to ensure safety.
2. Open the RO faucet and let the pressure release, ensuring a smooth transition for the next steps.
3. Carefully remove the blue safety clip, depress the collect, and disconnect the tubing from the membrane housing with precision.
4. Employ the wrench to expertly remove the membrane housing cap, preparing for the membrane change.
5. Use pliers to gently extract the used membrane, then discard it. Insert the new membrane, ensuring the end with two small washers goes in first. Push securely until it seats perfectly into the housing.
6. Securely replace and tighten the membrane housing cap, reconnect the tubing, and reattach the blue safety clip for a complete, leak-free setup.
Note: Should you encounter difficulty in replacing the housing cap, gently twist the RO membrane to seat it correctly to the pure water outlet, ensuring proper alignment.
