Installation notes
Ambient conditions
The following must be taken into account when installing the
membrane sensors:
• Select the sample water extraction point that guarantees a
proper mixture of disinfectant and a bubble-free sample water
flow.
• Keep the sample water extraction line as short as possible.
Please note
No water carrying lines made of copper piping may be installed.
These would distort the measurements.
• The membrane sensors can only be used in the DEPOLOX
®
5, DEPOLOX
®
Pool or VariaSens flow block assembly, which
maintains the constant sample water flow.
Because not all membrane sensors are designed for
pressurized operation, the operating conditions and the sensor
technical data must be reviewed and coordinated before the
sensors are installed in pressurized flow block assemblies!
• If the membrane sensor is not installed right next to the SFC,
the measuring cell cable can be lengthened up to no more
than 50m with a three-core, shielded cable. Ready- made
extension cables up to 15 m are available for this (see 8.
“Complete Units, Retrofit Kits and Spare Parts”).
The terminal strips with a right-hand direction of connection must
be used. Information on connecting the sensor to the sensor
module can be found in the wiring diagrams (see 9. “Wiring
Diagrams”).
