3. Transport and packaging
Pure water systems are carefully checked and packed prior to shipment but damage could nev-
ertheless occur during transport.
3.1 Examination on receipt
-Check the completeness of the goods received against the delivery note.
Is the packaging damaged ?
-Examine the system for damage.
3.2 Complaints
Should the system have been damaged during transport:
-Contact the post, railway or forwarding agent immediately*.
-Save the packaging and the outer cardboard carton (for a possible inspection and/or
return shipment of the system).
3.3 Packaging and return shipment
If possible, use the original packaging and materials.
Should these no longer be available:
-Pack the system in a suitable plastic bag or sheet and a strong cardboard box
-so that it is shock-proof.
*The time limit for claims is 6 days after receipt of the goods.
After this deadline, all rights to claims for damages are invalid.

4. Safety precautions
For your own safety, please observe the above safety precautions!
Your LabTower AFT system is a modularly constructed, pure water system that
serves exclusively for the purification of tap water.
Do not put the system into operation until you have taken notice of all of the appropriate
information that is given in these Operating Instructions.
Lifting and carrying the pure water system, e.g. to the installation location, should be car-
ried out by two people. To lift it, each takes hold of it under the base plate at two corners.
Note that the manufacturer is freed of all liability for damages that result from improper
operation of the system, or from use of it for other than the intended purpose.
The CE-Mark becomes invalidated should constructional changes be made to the system
or products of other manufacturers be installed in it.
Protect the system from frost. The temperature in the area in which the system is installed
must be at least +5° C and must not exceed +40° C.
Observe all regulations and requirements, including current accident regulations, that are
applicable and appropriate at the installation area, including those for the statics of the
flooring (see weight under „Technical specifications).
The raw water pressure must be at least 2 bar and at most 6 bar, should it be higher, then
an additional pressure reducer must be installed.
DIN EN 1717 requires that water purification systems be equipped with a safety device
that protects against contamination of the drinking water piping.
A grounded 100-250V / 50/60Hz socket must be available..
The installation area must have a drain at floor level with at least DN 50 pipe, otherwise
the manufacturer will not accept any liability for water damage. Should no such drain be
available, then a water watcher (240V only) (article no. 16.0129) must be installed.
Gravity fall to the waste drain must be ensured.
After long standstill periods (e.g. holidays), the system must be subjected to rinsing and, if
appropriate, disinfection. Refer to the section on ”Cleaning and disinfection“ for details.
When selecting the installation area and installing the system, make sure that there is
sufficient working area around the system for convenient operation of it.
Never look directly into a switched-on UV-lamp, as UV-light is dangerous to eyesight. The
UV-lamp is only to be replaced by authorized person to do this.
The guarantee is valid for a period of 12 months.

6. Intended use
The LabTower AFT pure water system is a reaction to the continually increasing requirements
that water of pure quality must fulfil, the increasingly strict demands resulting from technological
advances and the need for user-friendly systems and complete solutions.
LabTower AFT systems have been solely and specifically designed to excel in the intended use,
which is to produce sterile filtered pure water free of particles, salts and organic compounds.
To benefit from the long possible service lives of the high-quality purification media, feed the
pure water system with water which has been subjected to an upstream pre-treatment step (re-
verse osmosis, ion exchange or distillation),
- Analytical techniques in laboratories:
- HPLC ( H igh P erformance L iquid C hromatography )
- IC ( I on C hromatography )
- ICP ( I nductive C oupled Argon P lasma )
- AAS ( A tomic A bsorption S pectrophotometry )
- TOC Analysis ( T otal O rganic C arbon )
- DNA Research
- etc.
- Reagent and solution preparation:
- Cell culture media
- Tissue culture media
- Make-up water for reagents for on-line analytical systems
- Water for high-purity rinse processes on a laboratory scale
