8/ pH & ACL sensors cleaning
To ensure that the TRi PRO module will operate under optimal conditions, it is recommended to clean
sensors (ph and/or ACL) before each calibration.
To clean a sensor :
- If the extremity of the sensor is covered with a greasy film (cosmetics deposit, sun lotion….), place it for
a few minutes in tepid soapy water. Do NOT use detergent products but rather a liquid dishwashing
product. Then rinse profusely using clear water.
- If the extremity of the sensor is covered with calcium buildup or if the above procedure was not
sufficient, place the sensor in a 10% hydrochloric acid solution for a few minutes (wear all necessary
protective clothing).Then rinse profusely using clear water.
Remark
: It is possible to buy this acid cleaning solution from your local swimming pool retailer. Then
rinse profusely the pH tester with clear water and proceed with the calibration before using it.
IMPORTANT :
- Always clean pH & ACL sensors before performing a calibration.
- NEVER WIPE THE SENSORS WITH A CLOTH but shake it slightly in order to remove any excess
rinse water.
9/ TRi PRO module maintenance and winterizing
Using the TRi PRO module allows for more freedom when monitoring the pool parameters. However, it
is necessary to check a number of settings on a regular basis so as to ensure a correct and safe
operation of the system.
NOTE
: Your TRi PRO module uses a peristaltic pump that is designed to release only pH minus. Do
NOT use hydrochloric acid, pH plus or any other chemicals.
TRi PRO module winterizing :
- When you want to winterize your TRi PRO module at the end of the season, it is recommended to let it
pump clear water instead of the pH minus so as to rinse out the peristaltic pipe.
