Hydro 300 GPD RO Replacement Filter Bundle

RO Bundle: Step-By-Step Filter Replacement

1. Shut off the water supply to the RO system.

2. Close the RO tank valve.

3. Turn off or unplug any booster pump connected to the system.

4. Relieve the pressure. Open the RO faucet and let it run until the flow stops.

5. Place a towel and a small container under the system to catch water.

6. Remove each filter housing with the filter wrench. Turn counterclockwise and support the housing as it comes free.

7. Remove the old filters and rinse the housings with clean water. Check that each O-ring is clean, seated correctly, and undamaged.

8. Install the new filters in the correct stages. Follow the labels on the system or the bundle instructions. If you disconnect any tubing, note where it goes first and reconnect it to the same fitting.

9. Reinstall the housings. Start each one by hand to avoid cross-threading, then hand-tighten until snug. Don’t overtighten with the wrench.

10. Keep the tank valve closed. Slowly reopen the water supply, then turn on or plug in the booster pump if the system has one. Check for leaks.

11. Flush the filters for about 5 minutes through the RO faucet to clear carbon fines. Keep the tank valve closed during this flush.

12. Check for leaks again, then open the tank valve. Allow the tank to refill, then discard the first few minutes of water from the RO faucet.

If you see a leak, shut off the water and pump, relieve the pressure, and check that the housing is straight and the O-ring is seated properly. Follow the instructions supplied with your specific system if they differ.
