Adjust immersion depth of evaporator flask

The lift is used to immerse the evaporator flask in the bath fluid. To use the same
immersion depth for all distilling jobs, we recommend to firmly set immersion depth.
To this end loosen black rotary knob (22, fig. 15) on lift column by turning CCW ("unlock").
Vertical stop (15, fig. 17) drops (sustain by pulling down). Descend lift until reaching proper
immersion depth in heating bath (2). It may be required to sustain this action by hand. Pull
rotary knob tight (22, fig. 15) by turning clockwise ("lock"). At this point, immersion depth of
the evaporator flask is set permanently.
