❼ Care; I Cleaning The Sensors - Zodiac Hydroxinator iQ Series Instructions For Installation And Use Manual

7.1 I Cleaning the sensors

The sensors must be cleaned every 2 months.
• Stop the filter pump.
• Close all valves.
• Remove the sensor and the sensor holder from the POD.
• Rinse the sensor in tap water for 1 minute.
• Shake it to remove any residual water.
To prevent damage to the active part, do not rub and do not dry with a cloth.
• Brush the junctions and the metal part (Gold) for the ORP sensor using a toothbrush for 1 minute.
• Prepare a solution of diluted hydrochloric acid by pouring 1 mL (10 drops) of commercially-available
hydrochloric acid (HCl 37 %) into 50 mL of tap water (1/2 glass of water).
• Hydrochloric acid is a hazardous chemical that may cause burns, lesions and irritations.
Handle with care and use protective equipment (gloves, safety glasses, overalls). Refer to the
product's MSDS for more information.
• Always pour the acid into the water.
• Once cleaning is complete, dispose of the solution according to the standard in force in the
country of use.
• Wash the sensor in the diluted hydrochloric acid solution for 2 minutes.
• Rinse the sensor in clean water under the tap for 1 minute.
• Shake it to remove any residual water.
• Then calibrate the sensor, see "5.3 I Calibrating the sensors (if an optional "pH Link" or "Dual Link"
module has been installed)".
• Reposition the sensor holder and the sensor on the POD kit.
