5.1 Maintenance
5.1.1 General instructions
•
Always perform the maintenance work wearing suitable protective clothing.
•
Before disconnecting the device from the process, the pipelines or tanks must be
depressurised, empty and clean.
•
Check the process connection for leakages at regular intervals. If required, tighten the
pressure screw to a maximum torque of 10 Nm.
•
Structural modifications must only be implemented upon consultation with the
manufacturer.
5.1.2 Cleaning the measuring windows
The absorption (as well expressed as total suspended solids or in some applications as turbidity)
is measured using two measuring windows (sapphire) in the process. Contaminations or
coatings on the windows will cause the measured value to drift or be wrong.
To avoid any damage, do not focus high pressure cleaning "jets of water" directly at the optic.
In particular never clean the optic with tools or other mechanical objects. Do not insert hard
objects into the optical path.
Cleaning procedure
•
Remove the device from the process connection.
•
Clean the measuring windows from coatings using appropriate cleaning and rinsing solutions
in combination with a soft tissue.
CAUTION!
Make sure that only authorised and trained personnel perform maintenance work.
