CF Control Commissioning
11.2 Cleaning the measuring cell
Normally the measuring cell requires no inside cleaning. If the red float for the
monitoring of sample water should "get stuck", you can try to get it moving again.
Turn the sample water off for this purpose and unscrew the grey, ribbed water inlet
out of the measuring cell. Place a bucket below the cell before doing that. There are
two O-rings in the inlet of this measuring cell that must be inserted again when
reinstalling the cell. If you insert only one O-ring by accident, the pressure of the
sample water cannot push the float upwards.
11.3 Wintering
If the measuring and control system is installed outdoors (shaft etc.), the complete
system is to be disassembled and stored according to section 2 - Technical Data
(observe permissible room temperature and humidity!). Otherwise, errors can occur
in the devices due to condensation.
Please take care of the two O
rings during installation!
