Adjust Solvent Dosing Chamber Sensors
Each CAV 4.2 bath has its own solvent dosing chamber, mounted on the side panel. Optical sensors on
the inlet and the outlet of the dosing chasing must be adjusted to "see" the solvents that are drawn past
them.
When the chamber is full of solvent, adjust the sensors by turning the set screws counter-clockwise until
the associated green light turns on. When running multiple solvents, verify each solvent, always
adjusting by turning the screws counter-clockwise. See Figure 27.
