RO Membrane Replacement
I.
Turn off Cold Water & Tank Valve:
Turn cold water supply and tank ball valve to OFF
positions. Turn system faucet to the ON position to release any built up pressure in the
RO system. Once pressure has been released, turn system faucet to OFF position.
II. Remove Tubing from Housing:
See

Remove BLUE tubing lock clip and remove
the tubing from the cap of the RO housing on the main system bracket. Using the pro

V. Check for Leaks:
Turn cold water supply and tank ball valve to ON positions. Check
valves, fittings, tubing connections and housings to ensure there are no leaks.
VI. Flush Membrane:
Allow the RO system to run for approximately 3 hours to fill the tank.
When the tank is filled, the RO system will automatically shut-off. The first tank of water
must be drained to flush the new RO membrane. Do NOT use the first tank of water.
Turn the RO system faucet to the ON position to drain the tank. The tank is empty when
there is a noticable drop in water pressure from the RO system faucet. Once the tank is
empty, turn the system faucet OFF.
