Installation
5.2.3 Installing sensor in CCA151 assembly
The disinfection sensor (membrane-covered, ⌀25 mm) is designed for installation in the
Flowfit CCA151 flow assembly.
Please note the following during installation:
‣
The flow rate must be at least 5 l/h (1.3 gal/h).
‣
If the medium is returned to an overflow basin, pipe or similar, the resulting
counterpressure on the sensor must not exceed 1 bar (14.5 psi) and must remain constant.
‣
Avoid negative pressure at the sensor, e.g. due to medium being returned to the suction
side of a pump.
‣
To avoid buildup, heavily contaminated water should also be filtered.
