5.2 Tests prior to assembly
1. Use the label on the container to
check whether the desired chemical is
in the container.
»
In addition, an electronic chemical
comparison should be carried out via
barcode or RFID.
2. Make sure that the container is placed
in a dust-free environment.
NOTE
Contamination and debris can limit the
functionality of the fill head and lead
to premature wear of seals and thus to
leaks.
3. Carry out a visual inspection for the
following points:
•
Contamination and adhesion of
chemical residues. The fill head
must be clean.
•
Make sure there is no damage
such as cracks, etc.
Assembly/commissioning
WARNING
Hazard from chemicals!
A closed or incorrectly connected venti-
lation line will cause the pressure equal-
ization in the container to fail. Excess
or negative pressure can occur in the
container. Chemicals may leak out.
• Make sure that the ventilation line is
not blocked and is correctly connect-
ed.
• Wear the necessary personal pro-
tective equipment (PPE) (suitable
protective clothing, protective gloves,
respirators and safety goggles / face
shield).
4. Check that the ventilation line is con-
nected to the vent port and that the
ventilation line is free, i.e. not blocked
or kinked.
5. Check the connecting couplings. They
must not be too tight or too loose.
»
Use the correct tightening torque that
matches the screw connection.
Please use recommended torque
specifications of the respective man-
ufacturer when tightening nuts and
screws.
»
The screw connections must be se-
cured against unwinding.
When using flare connections,
see also AS flare and assembly in-
structions.
