Dosing systems for swimming pools
13.0 APPENDIX 3 – FREE CHLORINE MEASURE CELL (CL)

Operating temperature: 0 to 45° C.

Water conductivity: > 10 μ S/cm.

Maximum working pressure: 0.5 bar.

Output signal: 4÷20 mA current proportional to the ppm reading.

Power supply: 12 Vdc ± 1 V.

Electrolyte life: approx. 3 months (or less if the chlorine concentration is high).

Membrane life: approx. one year (depends greatly on the quality of the water).

A device must be used for the calibration, in order to determine the content of free chlorine according to the
DPD method (it is recommended to use a photometric instrument).

The reading of the free chlorine measure cell supplied is slightly affected by the variations in pH (range
4÷12 pH).

Installation procedure

Probe polarization is required on the first installation. After having connected the probe to the
Technopool3, immerse it in a container of water at 0 ppm and leave it for an hour.

The membrane is extremely sensitive! When removing or tightening the membrane cap, make sure
the membrane is not damaged with the high or low pressure.

 Connect the wires to the terminal (4). (+ brown / - blue).
 Tighten by hand (2) until the O-Ring (3) isolates the system.
 Close the PG7 cable gland securely (1).
