Assembly/commissioning
3. Mount the dispense head on a con-
tainer filled with ultra pure water. For
assembly, see the section “Mounting
the dispense head”.
4. Perform a test run with ultra pure wa-
ter and check the following points:
•
Tightness of the connections and
interfaces,
• Closing behavior of the valves;
the valves (check valve, plug
valve (turncock) or ball valve)
must seal completely,
• Ventilation of the container at
maximum flow rate.
If no pressure range is available/
measurable, visually check that
the flow rate is constant and that
the container does not inflate or
collapse.
CAUTION
Danger due to leaks!
Exceeding the maximum flow rate can
lead to leakage.
• Take suitable protective measures
against exceeding the maximum flow
rate.
5. Check/test the chemical resistance
of the dispense head for the chemical
used.
» On our website you will find a data-
base with some data on chemical
resistance, which can be used as a
guide.
