Cooling water outlet
⑥
Depending on the model, cooling water drains through one or two hose connections from the unit. The hoses for cooling
water outlet must lead into a drain on a lower level. The hoses must have a slope on their complete length, cooling water
must flow off without causing backwater. The cooling water hose must be ½", should not exceed a maximum length of approx.
1 m and must be temperature-resistant.
Caution:
The cooling water leaves the Distillation Apparatus with temperatures up to 70 °C.
Danger of scaldings!
Drain Bi-stage boiler
⑦
Only fitted in Glass Distillitation Apparatus models PD 2DG and PD 4 DG.
By opening the drain cock, mono distillate can be withdrawn from the bi distillate boiler. During normal operation, the drain
cock must be closed. Only then the bi distillate boiler will be filled and switched on. A ½" hose to drain the boiler for cleaning
or maintenance can be connected.
Caution:
Distilled water leaves the boiler of the Distillation Apparatus with temperatures up to 100 °C.
Danger of scaldings!
Waste water drain
⑧
When the function Clean (water exchange) is activated, impure water drains from the boiler through the connection
waste water drain. Connect a ½" hose with a maximum length of approx. 1 m. The hose for waste water outlet must by all
means lead into a drain on a lower level, it must have a slope on its complete length and must not be obstructed. Make certain
that the hose can draw air at the end of the cleaning cycle in order to cut off the water contact between two electrodes
inside the Distillation Apparatus.

After assembly of all power and water connections, the cut-off valves of the main water supply (pos.

) must be opened and the main switch has to be switched on. The distillate
produced during the first 5 to 8 operating hours (mono and bi distillate) should not be used.
During down-times of the Distillation Apparatus, all cut-off valves of the water supply must always be closed.
