is designed for dispensing liquids directly from the reservoir
bottle. The instruments are, according to the requirements of the DIN EN ISO 8655-5, DE-M marking and
optionally equipped with recirculation valve.
When the instrument is properly handled, dispensed liquid will only come into contact with the following
chemically resistant materials: various fluoroplastics (ETFE, FEP, PFA, PCTFE, PTFE), Al

sapphire and plati-
num-iridium or tantalum, depending on the design (see label on the dispensing tube and recirculation valve).
Please read the following carefully!
2. Functions and Limitations of Use
!
1.
Every user must read and understand this
operating manual before operation.
2.
Follow general instructions for hazard preven-
tion and safety instructions; e.g., wear protec-
tive clothing, eye protection and gloves.
3.
Observe all specifications provided by reagent
manufacturers.
4.
When dispensing inflammable media, make
sure to avoid the buildup of static charge, e.g.,
do not dispense into plastic vessels; do not
wipe instruments with a dry cloth.
5.
Use the instrument only for dispensing liquids,
with strict regard to the defined limitations of
use and operating limitations. Observe opera-
ting exclusions (see page 29)! If in doubt,
contact the manufacturer or supplier.
6.
Always use the instrument in such a way that
neither the user nor any other person is
endangered. When dispensing, the discharge
tube must always point away from you or any
other person. Avoid splashes. Only use suitable
vessels.
7.
Never press down the piston when the dis-
charge tube closure is attached.
8.
Never remove the discharge tube while the
dispensing cylinder is filled.
9.
Reagents can accumulate in the screw cap of
the discharge tube. Thus, it should be cleaned
regularly.
10.
For small bottles, and when using the flexible
discharge tube, use a bottle stand to prevent
tipping over.
11.
Never carry the mounted instrument by the
cylinder sleeve or the valve block. Breakage or
loosening of the cylinder may lead to personal
injury from chemicals (see page 33, Fig. 4).
12.
Never use force on the instrument. Use
smooth gentle movements to operate the
piston upwards and downwards.
13.
Use only original manufacturer's accessories
and spare parts. Do not attempt to make any
technical alterations. Do not dismantle the
instrument any further than described in the
operating manual!
14.
Always check the instrument for visible dam-
age before use. If there is a sign of a potential
malfunction (e.g., piston difficult to move,
sticking valves or leakage), immediately stop
dispensing. Consult the 'Troubleshooting' sec-
tion of this manual (see page 48), and contact
the manufacturer if needed.
15.
The screw coupling between the valve block
and the dispensing cylinder must always be
firmly tightened.
16.
The instrument should not be autoclaved.
