1 Use oft he Distillation Apparatus
Intended Use 1.1
In LAUDA Puridest Distillation Apparatus models PD 2 R, PD4 R, PD 8 Rand PD 12 Relectric heatingelements serve
to boil water andevaporate 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 2litres (PD 2 R), 4litres (PD 4 R), 8litres (PD 8 R) and
12litres (PD 12R).
Dependingon the tap water quality, the produced distillate hasa conductivity ofapprox. 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
16.2to 16.4 of these instructions on the possible use of filters and cartridges to pretreat the tapwater.
The Distillation Apparatus must be operated within the user's field of vision.
The information contained in these operating instructions must by all means beread and observed. Only
then a perfectoperation of the Distillation Apparatus can be guaranteed. The units mayonly 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 betouched after they have cooled down, or when wearing suita-
ble safety gloves.

7 Initiation
Before initial starting 7.1
Before initialstarting,the Distillation Apparatus has to be hand-filled with water. To do so, remove the outer and left-hand
inner lids (marked L) as well asthe deflector beneath the inner lid. Caution, when working on the deflector, make sure to
observe the correct position of the wireelectrode in the container. It may neither be bent nor come into contact with the
housing. The boiler must now be filled with water until the heating element(s) at the bottomof the container are below
water level. The deflector as well as the two individually marked inner lids must be re-assembled and safely nested on the
containers before initiation ofthe unit.

Initiation 7.2
To initiate the Distillation Apparatus after assembly of all power and water connec-
tions, open the hand-stop valveof the water mains supply ⑤and switch on the
main switch (I).The first few litres of produced distillate should not be used. Dis-
card the first two to three complete fillingsof distilled water inthe storage tank.
I II III
To switch off the unit for longer down-times, first switchthe main switch (I) to position O, and discon-
nect the unit from the mains. Close theon-site hand-stop valvesof the water supply, thenempty and dry
storage tank andboiler in order to avoid germ contamination.
8 Functional Description
LAUDA-GFLDistillation Apparatuses Puridest work automatically. After switching onthe Distillation Apparatus main
switch, the green pilot lamp in the main switch (I) as well as the right-hand, yellow operation pilot lamp (III)will light up.
The built-insolenoid valve opens. Water flows through the cooling coil in the storage tank and a mechanical water level
regulator that controls the water level in the boiler. Excess water that is not usedto evaporate,runs off through the cooling
water outlet. The heating elements are powered on and bring the water in the alembic to the boil. A thermostatic low water
cut-off protects the heatingelements from dry running. The produced steam is led through a steam tubeto the cooling
coil where it condenses and drips as distillate into the storage tank.
The water level inthe storage tank (right-hand container) is controlled through a wire electrode. Once the container is full,
the Distillation Apparatus will be switched off by an electronic controller. The solenoid valve interruptsthe cooling water
supply, the heating elements are switchedoff and the yellow pilot lamp (III) goes out. Distillate is withdrawn through the
black plastic tap at the front of the unit.
After withdrawal of distillate, the unit will be switchedon again automatically, so that thestorage tank is refilled.
Carbon dioxide is degassed through a vent on the top of the unit.

9 Maintenance, Service and Trouble Shooting
Caution:
Prior to maintenance and service on the unit let the Distillation Apparatus cool down!
Danger of burns!
Caution:
Before opening the Distillation Apparatus as well as prior to cleaning, separate the unit
from the mains supply! (Pull the plug or switchoff main switch).
Danger of electrical shock!
Descaling 9.1
Dependingon the degree of hardness of thetap water,the Distillation Apparatus must be cleaned regularly of scale for-
mations. First remove the outer and the left-handinner lids (L), then unscrew the deflector and remove it, too. Asuitable
descaling agent is amixtureof 10 % formic acid, 10% acetic acid and 80 % distilled water. Fill the solvent into the boiler
until it covers the topmost scale deposits andheat up to maximum approx. 70 °C.Make absolutely certain not to bring the
mixture toa boil. In order to do so, close the hand-stop valve ofthe water mains supply ⑤and switch on the Distillation
Apparatus until the temperature is reached. After approx. 30 minutes drain the solventand scale mixture through the
drain cock "drain boiler" ②andrinse 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 in-
structions (e.g. rea-calc®of M/s CHEMOTEC GmbH, 63486 Bruchköbel, Germany). Never use any products con-
taining hydrochloric acid! These will lead to damages to heatingelement, 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 firsttwo to three complete fillings of distilled waterin the storage tank.
Pilot Lamp Clean 9.2
9.2.1 Foam formation caused by polluted water in the boiler
Depending on the degree of impurities inthe feed water as well as onthe grow-
ing contamination of the water in the boiler, causedby 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 offthe unit, and the
red pilot lamp Clean (II) will light up.
The boiler must now be emptied through the drain cock "drain boiler" ②and be
rinsed several times with clean water..
I II
The operational interruption "Clean" is reset byswitching the unit's main switchoff and then on again. The subsequent re-
initiation is to be carried out as described in chapter 7.
The "Cleaning" function's purpose is to exchange polluted water in the boiler against clean water.

9.2.2 Back waterin the boiler
If the water level inthe boiler rises up to the wireelectrode in the left-handcontainer (L), the electronic impurity detector
(A1 in the circuit diagram) switches the unit off and the red pilot lamp "Clean" (II) lights up. This means thatmore water
entered the unit than could flowoff. Possible causes are tubesoutside the unit that are not installed as described (see
chapter 6), orscale formations that cause a blockage in the water outlet tube insidethe unit. A defective quantity regula-
tor in the outlet of the solenoid valve (see cooling water requirement, chapter 11) might also cause more water to flow
into the unitthan can flow off.For troubleshooting purposes, an additional function drawing ofthe internalwater flow is
available onrequest.
Re-initiation after low water 9.3
To re-initiate, let the unit cool down and fill in water to coverthe heating elements
as described in chapter 7 Initiation.
The triggered lowwater cut-off must be reset. To do so, loosen the black capnut at
the bottom left-hand side of the Distillation Apparatus. Insidethe thread a small
white plastic pin can be seen that has to be gently pressed inside (e.g.with a pen)
until a clicking sound can beheard.
Only then switchthe unit back onagain.
The LAUDA-GFL Distillation Apparatus Puridest is made of first-class material. Nevertheless, the unitshould only be
subjected to mechanicalstrain withinsensible limits.
Make sure that no fluids come into contact with cable connections or the
electrical parts inside the unit!The powder-coated surfaces of the unit can be cleaned with mild detergents, if necessary.
Servicings, repairs or modifications must be carried out according to the General Engineering Standards by a competent
electrician.
Only original spare parts must be used. Always demand a detailed confirmation by the person in charge (company, date,
signature) onthe kind and volume of the tasks carried out.

The electrical connection must ensure an all-pole separation from the mainssupply. Installed assembly parts,such as
shock-proof sockets or mainswitches, must be installedso as to ensure clear identification and they must be within easy
reach in anemergency case. Distillation Apparatusmodels PD8 R and PD 12 Rmust have a permanent connection with
the mains. This may only be implemented through an on-site main switch or through a CEE plug in conformity with IEC
standard 60309-2 (seeexamples for connection to themains in chapter 13.1).
