6.2.1 Replacing or cleaning cuvette
To remove the glass cuvette from the ultrasonic cuvette with flow-through holder execute the
following steps:
• Shut-off the intake flow with the help of the shutoff clamp.
• Move the lock ring counterclockwise and remove the ultrasonic cuvette with flow-through
holder (details on page 21).
• Turn the cuvette counterclockwise to remove it from the ultrasonic cuvette with flow-through
holder.
• Take a new cuvette or clean the old one (clean the interior and exterior of the cuvette by
washing up with a detergent solution usual in trade at first, afterwards rinse the interior and
exterior with distilled or de-ionised water usual in trade).
• Reassemble everything in reverse order.
CAUTION!
Installation, assembly, start-up and maintenance may only be performed by appropriately
trained personnel. The regional occupational health and safety directives must always be
observed.
INFORMATION!
Each time a housing cover is opened, the thread should be cleaned and greased. Use only resin-
free and acid-free grease.
Ensure that the housing gasket is properly fitted, clean and undamaged.
INFORMATION!
Assembly materials and tools are not part of the delivery. Use the assembly materials and tools
in compliance with the applicable occupational health and safety directives.
CAUTION!
Never insert a cuvette with visible moisture or water on the glass or the transducer into the
upper part of the device! Otherwise this cuvette could destroy or damage the electronics or the
transducer! Always clean and dry the cuvette with a soft cloth just before inserting it. The
dehumidification system cannot remove large droplets of water, only residual moisture!
INFORMATION!
Measurement cuvettes used for both grabbing a sample and continuous flow measurement have
to be clean and free of marks or scratches. Otherwise the device cannot detect a proper
measuring result.
