Section 7 Taking out of operation
7.1 Taking out of operation for a short period
No special measures are necessary for taking out of operation for a
short period (up to a week in frost-free ambient conditions).
Important note: If the supply of power to the controller is
interrupted, frost damage may occur.
Ensure the instrument and tubing cannot freeze.
1. Interrupt the measurement and switch the analysis instrument
to the service state.
7.2 Taking out of operation for an extended period
If the filter modules may dry out (e.g. on cleaning the tank), in case
of risk of frost or if the filtration probe sc is to be taken out of
operation for an extended period, please work through the following
list:
1. Take the analysis instrument out of operation in accordance
with the operating instructions for the analysis instrument.
2. Isolate the filtration probe sc from the mains.
3. Take the filtration probe sc out of the tank.
Important note: Do not let the filter modules dry out, as dry filter
modules will become unusable immediately and cannot be
repaired.
4. Dismantle the filter modules.
5. Store the filter modules in clean water.
6. Wrap the filtration probe sc in protective film or a dry cloth.
7. Store the filtration probe sc dry.
7.3 Finally taking out of operation
When you want to finally take the filtration probe sc out of
operation, proceed as described for intermediate storage.
