7 Initiation and Setting of the Cooling Water Temperature
Lift the condenser from the boiler (ill. E, upwards arrow) and fill in water until the heating element in the boiler is com-
pletely covered by water.
Control Thermometer (ill. C) 7.1
Insert the supplied thermometer into the tube support on the right-hand of the upper part.
Water inlet and Setting the Cooling Water Temperature (ill. D and E) 7.2
Open the tap of the cooling water supply on the unit completely (handle in the direction of water flow), and the on-site
stop valve of the mains water supply a little. Check the power supply and switch on the main switch. The pilot lamp in the
main switch lights up. As soon as the water in the boiler reaches boiling point, regulate the cooling water supply on the tap
of the mains water supply so as to set the temperature of the draining cooling water to approx. 60 °C to 70 °C. The tem-
perature can be checked with the inserted thermometer. The Distillation Apparatus achieves its maximum efficiency with a
cooling water temperature of 60 °C to 70 °C.
Degassing and Distillate Withdrawal (ill. F) 7.3
Carbon dioxide that forms during the distillation process, is released through a vent in the condenser. Produced distillate is
to be led through a hose (not shown) from the drain tube into a storage tank.
