General Maintenance
The F-420 Flow Meter requires very little maintenance. However, the flow meter may become clogged due to excess debris in the water. If this happens, shut off the water and remove any pressure from the piping. Depending on the piping arrangement, either remove the piping section at the nearest union connection or adjust the piping supports to allow for the removal of the flowmeter. It may be necessary to cut piping to service the meter.
Remove the flow meter by unscrewing the adapters at the top and bottom. Pay attention to O-rings, float, and guide to avoid damage. Use a soft bristle brush and mild soap to clean the inside of the body and parts.
Reinstall the flow meter and test. If the float was removed during the cleaning process, ensure the float is correctly reinstalled. The float is wider at the top.
