  If your Magnetrol Measuring Instruments Tuffy fails to shut off or turn on inlet air, first check the float for a full range of travel, listening for a clicking sound from the mechanism. If the mechanism operates correctly when removed, ensure liquid is entering the storage tank or vessel, checking for closed valves or clogged pipelines. If the float is filled with liquid or collapsed, replace the entire level switch. Also, verify the unit is installed correctly with the serial number tag on top. If issues persist, contact the factory.

Why Magnetrol Tuffy 039-6000-100 Tuffy fails to shut off or turn on inlet air?

  The Magnetrol Measuring Instruments Tuffy may fail to shut off or turn on inlet air due to several reasons. The float might not have a full range of travel. Liquid might not be entering the storage tank or vessel because of a closed valve or clogged pipeline. Alternatively, the float could be filled with liquid or collapsed, requiring replacement of the level switch. Incorrect installation, such as the serial number tag not being positioned on the top of the unit, can also cause this issue. If these steps don't resolve the problem, further assistance from the factory may be needed.
