Replacing the Moen Flo Shutoff

1. To remove the old Moen Flo Shutoff from your plumbing system, verify that your main water supply is turned off.

2. Open a few faucets to relieve the water pressure or until water stops flowing from them. Leave the fixtures open until you install the new Moen Flo Shutoff device.

3. Using a wrench, loosen the 2 union nuts that secure your Moen Flo Shutoff device to your home's plumbing. Loosen by turning the hardware counter-clockwise.

4. Simply remove the Moen Flo Shutoff device once the union nuts are released.

5. Install the new Moen Flo Shutoff device and make sure that the o-rings are properly in place before securing the connection to the plumbing line.

6. Verify that the orientation of the Moen Flo Shutoff device is in the correct position - there are arrows marked on the Moen Flo Shutoff device indicating the direction of the water flow to your home fixtures.

7. DO NOT over-tighten the black polymer nuts when re-installing. Hand-tighten and use a 1/4 turn with your wrench to secure the Moen Flo Shutoff device.

8. Plug in the Moen Flo Shutoff device making sure to firmly push the power cord into the device. Note: turn until the second ring is completely in the Moen Flo Shutoff device.

Firmly push the power cord into the Moen Flo Shutoff Device.

Note: twist and turn until the second ring is completely in the Moen Flo Shutoff device.

9. Once the status LED is green, open your main shut off valve slowly, allowing water to gradually run through your Moen Flo Shutoff device and plumbing system.

10. While a fixture is open and running water, verify that the flow rate reading is being registered on your app through the control panel.

11. You can now close the opened faucets from step 2.
