3
Connect the water supply tube with filter to the water inlet connection on
the analyzer.

liquid level detector, so the filter, at the end of the water supply tube will be
long enough to reach the bottom of the tank.

through the opening of the tank, so the filter touches the bottom of the
tank, while the level detector with rubber stopper align vertically into the
tank.
