Switching lever
This lever is used to switch the unit from "pumping" mode to "filtering".
Optical differential pressure indicator
This switch monitors the pressure of the medium before and after the filter.
When the preset differential pressure is reached, the optical indicator changes from green to red. If the pressure differential
returns to a value below the preset limit, the indicator changes back to green, i.e. no manual reset of the indicator is required.
