Distillate is withdrawn through the black plastic tap (IV) at the front of the unit.
After withdrawal of distillate the unit will be switched on again automatically so that the storage
tank is refilled.
Carbon dioxide is degassed through a vent on top of the unit.
9. Maintenance, Service and Trouble Shooting
9.1 Descaling
Depending on the degree of hardness of the tap water, the Water Still must be cleaned regularly
of scale formations. First remove the outer and the left-hand inner lids (L), then unscrew the
deflector and remove it, too.
A suitable descaling agent is a mixture of 10% formic acid, 10% acetic acid and 80% distilled
water. Fill the solvent into the boiler until it covers the topmost scale deposits and heat up to
maximum approx. 70°C. Make absolutely certain not to bring the mixture to a boil. In order to
do so, close the hand-stop valve of the water mains supply ⑤ and switch on the Water Still until
the temperature is reached. After approx. 30 minutes drain the solvent and scale mixture
through the drain cock "drain boiler" ② and rinse the boiler thoroughly with water several
times.
Commercial descaling agents, suitable for use with stainless steel, can also be used according
to the manufacturer's instructions (e.g. rea-calc® of M/s CHEMOTEC GmbH, 63486
Bruchköbel, Germany).
Never use any products containing hydrochloric acid!
These will lead to damages to heating element, boiler,
temperature sensor and the ducts of the screw connections.
Restart the unit as described in chapter 7 Initiation.
After descalings, the first few litres of distillate should not be used as it might contain
traces of evaporated descaling agent. Discard the first two to three complete fillings of
distilled water in the storage tank.

Caution! Prior to maintenance and service
on the unit let the Water Still cool down!
Caution, before opening the Water Still as well as prior to
cleaning separate the unit from the mains supply!
(Pull the plug or switch off main switch)
Danger of electrical shock!
Depending on the degree of impurities in the feed
water as well as on the growing contamination of the
water in the boiler, caused by the distillation process,
the boiling water will foam up. Once the foam gets in
contact with the electrode in the boiler (L) , an
electronic impurity detector will switch off the unit,
and the red pilot lamp Clean (II) will light up.
The boiler must now be emptied through the drain
cock "drain boiler" ② and be rinsed several times
with clean water.
