1 Use oft he Distillation Apparatus
Intended Use
1.1
In LAUDA Puridest Distillation Apparatus models PD 2 R, PD 4 R, PD 8 R and PD 12 R electric heating elements serve
to boil water and evaporate it. The steam is led through steam tubes into the storage tank where it condenses on a water-
cooled cooling coil. The produced distillate drips into the storage tank. The storage tank level is electronically monitored,
the Distillation Apparatus heating element(s) and cooling water supply will be switched off when the tank is full. Depending
on the model, the distillate quantity per hour ranges between 2 litres (PD 2 R), 4 litres (PD 4 R), 8 litres (PD 8 R) and
12 litres (PD 12 R).
Depending on the tap water quality, the produced distillate has a conductivity of approx. 2.3 µS / cm at 25 °C. To feed
the Distillation Apparatus, preferably use tap water of drinking quality. Please also observe the information in chapters
16.2 to 16.4 of these instructions on the possible use of filters and cartridges to pretreat the tap water.
The Distillation Apparatus must be operated within the user's field of vision.
The information contained in these operating instructions must by all means be read and observed. Only
then a perfect operation of the Distillation Apparatus can be guaranteed. The units may only be installed
and operated by persons who have made themselves familiar with these operating instructions.
Caution:
The accessible inner parts of the housing, that can be reached after lifting the outer lid get strongly heated
up during operation. These parts may only be touched after they have cooled down, or when wearing suita-
ble safety gloves.
