Astralpool SEL BLUE EVO - 3-Sensor Calibration (for ORP); 4-BOOST Menu; 5-Production with Automatic Cover; 6-Auto-test

SEL BLUE EVO ENGLISH

If, after several hours, you notice that the ORP measurement remains low, you can activate the BOOST feature
(see BOOST) to restore it more quickly.
Warning: A heavy stabilising agent concentration may distort ORP measurements and lead to excess chlorine
production.
3-Sensor calibration
The sensors are calibrated upon leaving the factory. However, it is recommended to perform calibration upon
installation of the sensor.
The calibration must be verified at least once per year.
Calibration process:
Warning: Before calibrating the sensor, verify that no chlorination is occurring. If electrolysis is taking place, adjust
chlorine production to 0%.
1) Unscrew the cell as far as possible (it is not necessary to stop the filtering pump),
2) take the sensor out of its space, rinse it and wet it in the pH solution by shaking. When the value displayed
on the main screen is stable (1 to 2 minutes), go into "Sensor Calibration" in the "ORP Menu."
3) Adjust the value as close as possible to the calibration solution and validate.
4) Put the sensor back into its space on the cell, and then screw the cell into the vessel (Fig. 8.2).
5) Flush the cell (Fig 8.3).
6) Restore the chlorinator to normal production conditions (% prod.).
7) Return to main screen
4 -BOOST Menu
The BOOST feature helps maintain a maximum production level to achieve the required
chlorine concentrations of 0.5<ppmCL<3, mainly under the following conditions:
 First start-up of the chlorinator, if the chlorine concentration is <0.5ppm.
 Restarting the chlorinator after putting the pool into winter mode, if the chlorine concentration is <0.5ppm.
 Exceptional frequency
When you activate this feature, chlorine production is kept at its maximum level of 100% for 24 hours. The
wordiBOOSTiappears on the main screen. You can activate the boost at any time using the BOOST Menu -> Stop
boost
Warning: Make sure the filtering pump stays running throughout the duration of the BOOST.
Warning: The boost's duration is limited to prevent excessive chlorination of the swimming pool. If the pool is
covered, there is risk of excessive chlorination in the event of a lack of contact with the cover. In this case, please
monitor the chlorine concentration regularly.
5 –Production with automatic cover
This parameter is used to automatically reduce chlorine production when the
swimming pool is equipped with a chlorinating contact (Fig. 15). Factory setting: 50%.
The adjustment is made in % of normal production (production set in the chlorination
[electrolysis] menu). For example: if you have adjusted chlorine production to 60%
(chlorination menu), activating the flap contact will decrease production from 60% to 30% (50% of 60%).
6 –Auto-test
This feature is used to test the pH pump, electrolysis and cover panel. You can activate it
at any time.
Warning: Make sure that the filtering pump is running before activating the auto-test.
