LAUDA Puridest Distillation Apparatus models PD 2 R, PD 4 R, PD 8 R and PD 12 R with storage tank produce highly-
pure, bacteria and pyrogen free distillate with a very low conductivity (approx 2.3 µS / cm at 25 °C). The distillate is in con-
formity with DABregulations and the regulations of many international pharmacopeia..

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.
Improper Use 1.2
LAUDA Puridest Distillation Apparatus, operated in a laboratory, are no Medical Devices. They fall neither under national
nor international Medical Device Directives andhave to be used and applied accordingly. The Distillation Apparatus must
not be used in potentiallyexplosive surroundings. The Distillation Apparatus must neither be set upnor operated in labora-
tory areas with aggressiveor corrosive ambient conditions
2 Warranty
For all laboratory apparatus and their accessories from LAUDA-GFL Gesellschaft für Labortechnik mbH, there is a war-
ranty claim, as well for spare parts, repairs and modifications, carriedout by LAUDA-GFL. In order to identify defective
units, we require both model and serial number on the nameplate, left-handside of the Distillation Apparatus and, if appli-
cable, a copyof the invoice.

3 Before Initiation
Important information are marked in boldletters in these instructions, safety indications are additionally markedby the fol-
lowing warning symbols and mandatory signs.
Read and observe the
operating instructions
Warning of hot liquids
and vapour Warning of hot surfaces
Warning of dangerous
electrical voltage General warning Before maintenance and repair
disconnect the unit all-pole from
the electrical mains (pull the plug
from the socket).
4 Set-up and Location of the Distillation Apparatus
Protect yourself and the unit during transport and setupby workingcarefully and avoid danger of e. g.
shifting or tilting the unit as well as risk of injury by liftingheavyloads.
Caution, Distillation Apparatus models PD 4 R(net weight 21.8 kg), PD 8 R(net weight 35.8 kg) and
PD 12 R (net weight 40.9 kg) must be lifted, carried and transported to the location by at leasttwo
persons. The Distillation Apparatus can be held between the four stands ofthe unit and lifted for setup.
The unit is suitable for both bench and wall mounting. It is only suitable for indoor use. Table-top setting-up on solid, even
and levelsurfaces only. Make sure to placethe unit only on a watertight, temperature-resistant,non-flammablesurface.
The locationmust providesufficient space as well as the necessary carrying capacity for the total weight ofthe unit (unit
weight as per technical data, chapter 11 of this manual, plus weight of the filling).
For setting-upon the wall, check the carrying capacity of the wall in connection with the total weightof the unit (appli-
ance plus water filling, see Technical Data).Make sure to check the on-site fixing elements in order to guarantee safe hold
of the Distillation Apparatus. The fixing material must be suitable for the substrate. Use only tested and proven fixing ma-
terial.
There are two keyholes for wall mounting at the back ofthe Distillation Apparatus. Place two fixing screws (not included in
the scopeof supply) in the wall in the distance of the two keyholes and nest the Distillation Apparatus onthe keyholes. The
unit is delivered without fixing material.
Model / Distance ofscrews
PD 2 R / 40cm
PD 4 R / 48cm
PD 8 R / 64cm
PD12R / 64cm
The unit is notsuitable for use in potentially explosive surroundings, e. g.during anaesthesia with inflammable gas orsteam
types!

5 Operation Voltage
The Distillation Apparatus must be connected tothe mains supply either by a correctly installedshock-
proof socket, or, with a fixed connection,to an on-site main switch. TheDistillation Apparatus is a pro-
tection class I electrical appliance, a connectionto the earth conductor (PE) must be ensured. For
informationon the required mains fuse please view Technical Data, chapter 11 of this manual.
The electrical connection must ensure an all-pole separation from themainsat any time. Shock-
proof sockets or main switches to separate the Distillation Apparatus fromthe mains must be installed
in such a wayas to ensure they can be clearly identified and are easily accessibleat any time.
The mains connection cable must not touch any hot surfaces of the unit. It may not lead underneath
the unit. The main switch (I) of the Distillation Apparatus must be off (position O). The voltage on the
nameplate (at the left-handside of the unit) must be identical to the mains voltage. If they are identical,
connect the unit to the mains. Please also refer to chapter 13of these operating instructions "Connec-
tion to the Mains".
6 Water Connections
All water connections of the Distillation Apparatus, except thedistillate withdrawal tap onthe front, are situated on the
right-hand sideof the unit.
Hoses for water inlet and outlet are not included in the standard scope ofsupply.

Distillate withdrawal j 6.1
Distillate is withdrawn from the unit through the black plastic tap on the frontof the unit. It can be opened in continuous
or interval positions. A laboratory hose with an inner diameter ofapprox. 15 mm can be connected to the tap, the hose
has to besecured from slipping off with a hose clip.
Caution:
The distillate leaves the Distillation Apparatus with a temperature ofmore than 50 °C.
Danger ofscaldings!
Drainboiler k 6.2
Connect a ½" hose to drain the boiler when cleaningthe unit and/or carrying out maintenance works.
Caution:
the water leaves the boiler of the Distillation Apparatus with atemperature of up to 100 °C.
Danger ofscaldings!
Cooling water outlet l 6.3
Connect a¾" temperature-resistant hose to the cooling water outlet. It may have a maximum length of approx. 1.5m. It
must be led into an open drainon a lower level and must have a slope on its complete length.
Make sure the cooling water can drain without back draughts.
Caution:
cooling water leaves the Distillation Apparatus with a temperature of up to 70 °C.
Danger ofscaldings!
Tap water inlet m 6.4
The tap water inlet supplies water to the Distillation Apparatus through a solenoid valve. The hose connection of the valve
must be connected with the water mains through a ½" pressure hose and a blockable water connection (⑤, handstop
valve).
It is absolutely essential to use hose clips to secure both hose connections!
