The fluid waste from drain connection of this instrument contains reagents
diluted with large quantities of sample water. HF scientific recommends that
operators check with local authorities concerning proper disposal of waste
fluids. This waste fluid must NEVER be reintroduced into the incoming water
stream.
A ½ “ ID tubing can be placed over the cabinet vent to redirect accidental
spills of reagent to a suitable container.
