(Optional)
Install a 3/8" PEX tubing hose to the provided fitting and shut-off that connects to the inlet side of the
filtration system. Run the hose to a floor drain or bucket, and use to drain sediment or to aid in filter removal during change-out.

3 times to confirm that it is reset.

button pushed down until all the air or water pressure is completely released.
5. Push down the top cap with both hands to unseat the retaining ring.

completely out of the groove.
7. Remove the top cap of the system by lifting up on the top handles and remove the old filter.
(NOTE that filter adapter
(yellow/white in color) may come loose from bottom connection when removing filter, and should be reinstalled into the
bottom connection for proper installation of filter.)
8. Open the fitting and shut-off, and then flush out the bottom of the system.
9. Look down into the tank assembly and locate the small opening centered in the bottom of the tank.
10. Remove packaging from the new filter and place the new cartridge into the tank with the double O-ring facing down.
11. Position the cartridge so that it is aligned with the bottom center opening.
12. Press down on the cartridge so that the double O-ring seal moves into place within the bottom center opening.
13. Reposition the top cap into its original location.

16. Turn the water supply on and open the inlet and outlet valves on the bypass.
17. Relieve the system of air in the tank as the system fills with water by pushing down on the red depressurization button on
the top cap of the system. Keep the button pushed down until all the air pressure is completely released, and water comes
out of the red depressurization button.
