9.0 MAINTENANCE
The Eductor must be completely cleaned after each use. Lack of regular cleaning allows the foam concentrate to dry inside and around
the percentage ball resulting in plugged metering orifices. Look down inside the metering head after flushing and check valve to ensure
clean passageways.
