7.2 Water inlet and Setting the Cooling Water Temperature (ill. D and E)
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 temperature can be checked with the inserted thermometer.
The Water Still achieves its maximum efficiency with a cooling water temperature of 60°C to
70°C.
7.3 Degassing and Distillate Withdrawal (ill. F)
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.
8. Functional Description
The tap water flows through the cooling coil in the condenser to the water level regulator on
the right-hand side of the unit. The mechanical water level regulator determines the water
level in the boiler so as to ensure that the heating element is constantly kept below water
level. Water that is not used for evaporation flows off through the cooling water outlet.
When the heating element is switched on, it brings the water in the alembic to the boil. A
thermostatic low water cut-off protects the heating element from running dry. The produced
steam is led into the condenser, condenses on the cooling coil and drips off as distillate
through the drain tube on the front. By setting the cooling water temperature to 60°C to 70°C,
to be checked with the inserted thermometer, the unit's efficiency and the produced quantity
of distillate is optimised.
9. Maintenance, Service and Removal of Malfunctions
Caution! Before servicing the unit
let the Water Still cool down!
Danger of burns!
Caution, before opening the Water Still as well as before
cleaning procedures, disconnect the unit from the mains!
(Unplug the unit or switch off the main switch).
Danger of electrical shock!
