General Maintenance
The F-452 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.
The F-452 flow meter can be removed via the union adapters. Unscrew union nuts on both sides of the flow meter to remove the meter body. Pay attention to O-rings, float, and guide to avoid damage.
If the F-452 Flow Meter is panel mounted, the meter body can be removed from the adapters by unscrewing the unions on the top and bottom. The complete flow meter can also be removed by disconnecting piping from adapters. Remove the flow meter by unscrewing the panel nuts at the top and bottom. Remove the top cap and remove the guide rod and float. Remove top and bottom flow meter adapters for cleaning. 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.
