Troubleshooting
The technology upon which the Autotrol Performa control
valve is based is well established and proven in service
over many years. However, should a problem or question
arise regarding the operation of the system, the control
can very easily be serviced. For parts mentioned, refer to
exploded views in the Replacement Parts section of this
manual.
