1 General information
1.1 Introduction
These operating instructions are only valid
for the products mentioned in the title.
The gures shown are only exemplary
illustrations. Depending on the equipment
and conguration, the actual appearance
of the ll head may vary.
These operating instructions convey im-
portant notes for the safe and efcient han-
dling of the products. They are part of the
products. The prerequisite for safe working
with the products is the compliance with all
specied safety instructions and directives.
The operating instructions refer to standard
versions. For special versions that are not
described in these operating instructions,
the basic information in these operating
instructions applies in conjunction with
additional special documentation.
The operating instructions are the basis for
all training courses that take place with the
products.
• Please read the operating instructions
carefully before using the products.
• Please read the safety instructions.
• Store the operating instructions in a
safe and accessible place during the
service life of the products.

1.3 Symbols and labels
The following symbols are used in these
operating instructions to depict hazards
and notes:
DANGER
Indicates a hazard which, if not avoided,
will result in death or serious injury.
WARNING
Indicates a hazard which, if not avoided,
could result in death or serious injury.
CAUTION
Indicates a hazard which, if not avoided,
could result in minor or moderate injury.
NOTE
Designates a situation that can result in
material damage.
1.4 Copyright protection
Despite all care taken, data and character-
istics can change – even at short notice.
We therefore do not assume any liability
or guarantee for the topicality, correctness
and completeness of the information.
Figures, graphics and texts as well as the
design of these operating instructions are
subject to copyright protection and other
protective laws. Duplication – also in ex-
cerpts – requires the prior written consent
of AS Strömungstechnik GmbH, if duplica-
tion is not legally permitted.
General information
1.5 Guarantee and warranty
AS Strömungstechnik GmbH assumes no
liability for errors or damage that occurred
due to improper handling of the products.
Improper handling is in particular in the
event of non-compliance with the operating
instructions, incorrect handling, negli-
gence, unauthorized replacement of parts
and other interventions.
The customer is responsible for testing the
chemical resistance of the ll heads and
their service life.
Fill heads and other products which have
come into contact with media/chemicals
(except ultra pure water) cannot be taken
back.
AS Strömungstechnik GmbH reserves the
right to make design changes due to fur-
ther development of AS products.
Our customer service is always available
even after the guarantee period has ex-
pired.

2 Safety
Please observe the following notes to pre-
vent malfunctioning, damage and injuries.
2.1 Intended use
The QC2 and G-Series ll heads are de-
signed for the clean and safe lling/recircu-
lation of neutral or inorganic liquid chemi-
cals into transport containers which do not
adversely affect the physical and chemical
properties of the materials and substances
of which the ll head used is composed.
The QC2 and G-Series conductive ll
heads are designed for the clean and safe
lling/recirculation of neutral or organic
liquid chemicals into transport containers
which do not adversely affect the physical
and chemical properties of the materials
and substances of which the ll head used
is composed. They are electrostatically
safe in the sense of the Cenelec Technical
Report TR 50404: 2003 and therefore ap-
plicable in zones 1 and 2 for liquids of the
entire explosion group IIA.
Fill heads may be used only in conjunction
with AS dip tubes of the series correspond-
ing to the ll head. Observe the operating
instructions of the dip tube.
The ll heads are designed for use with
pump systems.
For dispensing and withdrawal applica-
tions, refer to the operating instructions
for dispense heads of the corresponding
series.
2.2 Improper use
Any use other than the one described in
the Section “intended use” is deemed to
be inappropriate use. The operator of the
products shall be solely responsible for any
resulting damage.
2.3 Responsibility of the user
Operator means any natural or legal per-
son who operates or controls the device or
makes it accessible to third parties for use
and who is responsible for the safety of the
user or third parties.
• In particular, observe the general
safety and occupational safety regula-
tions of the BG Chemie in Germany or
the responsible regional professional
association for chemistry and health
(e.g. OSHA in the United States), the
applicable technical rules for haz-
ardous substances, the Hazardous
Substances Ordinance, the CLP Or-
dinance, the company own standard
operating procedures (SOPs), as
well as the regulations of the ATEX
Directive, the technical guidelines
“Flammable liquids” and the explosion
protection guidelines of the BG Che-
mie in Germany or the responsible
regional association / authority for
applications in hazardous areas.
• If ammable liquids are “splash lled”
into the container, the applicable
national and international regula-
tions and guidelines must also be
observed (e.g. BetrSichV incl. TRBS
2153, 4/2009 (Germany), Cenelec
Technical Report TR 50404: 2003
(EU), IEC 60079-32 (international),

JNIOSH-TR-No.42 2007 (Japan),
NFPA Recommended Practice on
Static Electricity (USA). It must also be
checked whether a correspondingly
long dip tube can be used for the re-
turn / lling into the container, which
enables lling below the liquid level.
• These operating instructions do not
replace the company’s own standard
operating procedures (SOPs).
• Wear appropriate protective clothing
when handling chemical substances.
• Ensure that the ll heads are not used
after the maximum period of use has
expired. The duration of use depends
on the chemicals used.
• Before using the products, check the
materials for their chemical resistance.
2.4 General safety instructions
• Always observe the safety data sheets
(SDS) of the chemicals used.
• Only use cleaned products. The prod-
ucts described in these operating
instructions have been cleaned in an
ultrasonic bath at the factory.
• Only use products for which the chem-
ical resistance of the components is
guaranteed.

have a check valve, a limit switch and
a overlling sensor (DH-RBU-...).
The electrically conductive version
with limit switch, manual shut-off valve
or second vent port is also available.
Depending on the design, the ll head may
look slightly different.

The ll head is generally equipped with:
• Liquid line connection to inlet of uid
pump line connection
• Vent line connection
• Code disk
• Tightening nut with red anti-rotation
clip
• Standard connection to mating dip
tube
Depending on the option, the uid ow rate
in the liquid channel can be controlled by
a check valve, a plug valve (turncock) or a
ball valve.
The check valve ensures that there is no
ow back after transfer is complete and
there is no spill at disconnection. As soon
as the pump is activated, the check valve
opens. When the pump is switched off, the
pressure in the lling line is reduced and
the check valve closes.
The optional limit switch ensures that the
ll head is correctly mounted. The lling
process can only be started after the re-
lease signal from the limit switch.
» The incorporation of the limit switch
requires professional installation to
integrate the signals into the system
control (PLC) to properly operate.
To ll ammable or highly ammable
chemicals into a container, there is an
electrically conductive version of the ll
head and the dip tube.
» The MOC of electrically conductive
plastic ll heads and dip tubes is al-
ways black in color due to the carbon
additive.
WARNING
Danger due to static charge.
Statically charged chemicals or ll
heads, dip tubes, etc. can cause sparks
to arc creating an ignition source.
• Ground the dip tube and ll head
properly.
