SEL BLUE

15. TROUBLESHOOTING

PROBLEM FOUND
Filtering medium clogged or
contaminated
Water balance problem. Check the
water's chemical parameters.
1- Low chlorine
Insufficient filtering time
level that cannot
be raised.
Lack of stabilising agent in the pool with
major exposure to UV and/or high use
Electrode-level problem
Saturated sensor
2- pH/ORP values
Presence of air bubbles at the vessel's
are extreme or
head
unstable
Defective sensor
Contaminated or outdated calibration
solution
3- Impossible to
calibrate the
Sensor clogged or covered in limescale
pH/ORP sensor
Defective sensor (damaged membrane...)
Certain sensors respond more slowly
than others do. In such cases, wait a few
hours until stabilisation occurs.
4- Slow sensor
response
Insufficient flow rate in the electrode
measurement chambers

POSSIBLE SOLUTION
Use a filter cleaner or replace the filtering medium.
pH [7.2 - 7.6] / combined chlorine (DPD3) < 0.6 ppm
/ stabilising agent [20 - 30 ppm] / TAC [80 - 120 ppm]
/ TH [180 - 250 ppm
Increase the filtering time (filtering time in h = water
temperature / 2)
3
Add 20 to 30 g/m of stabilising agent (cyanuric acid)
Check the electrode's connection, as well as the
production of chlorine gas bubbles in the vessel.
Immerse the sensor in a hydrochloric acid solution
diluted to 10% for 1 hour.
Flush out the measuring chambers while softly
unscrewing the sensor-holder and holding the
sensor in place.
Replace sensor
Replace the calibration solution
Clean the sensor in accordance with the procedure
indicated in the chapter on ORP & pH sensor
maintenance.
Replace sensor
Clean the sensor with clean water and drain the
excess by shaking slightly without rubbing.
If the problem continues, follow the instructions in
Point 2-
Make sure the water is flowing properly in the
electrode measurement chambers and that there
are no air bubbles (flush if necessary).
