Introduce Sample Flow
Apply power, slowly open the sample point isolation valve (not supplied) to start flow to
the sensor. Allow approximately 3-5 minutes for the sensor to fill, and observe flow at
the drain tube. Once there is flow, check that there are no leaks inside the sensor enclo-
sure. Allow the sensor to initially flush with sample water (4-24 hours is recommended).
Close front cover and connect the M300TOC patch cable to the connector on the bottom
left side of enclosure.
