Installing Ph & Acl Sensors - Zodiac TRiPRO Notice De Montage

3.4/ Installing pH & ACL sensors
For an optimal function, you should follow all the steps below before installing sensors into the POD.
Note : - pH sensor (blue, part #2) is made for reading the pH of pool's water.
- ACL sensor (red, part #3) is made for reading Redox potential (ORP) of pool's water to
automatically adjust chlorine generation (« Active Chlorine Level ») of TRi salt water chlorinator.
 Follow instructions hereafter for both pH & ACL sensors.
1. Carefully remove the small protection bottle that contains a preservative liquid by unscrewing its cap.
2. Rinse the end of sensor with clear tap water, then shake off any excess of water.
WARNING : Never wipe sensors with a cloth or a piece of paper as this could damage it !
3. Set the 2 bottles containing the preservative liquid aside for long term and wintering storage. Empty
the preservative liquid solution, filling it with tap water will be sufficient when storing pH & ACL sensors.
4. Introduce pH & ACL sensors (parts #2 & #3) into their respective sensor holders and tighten locking
rings by hand. Ensure that sensors are not inserted too far into their housing (see following picture with
red dotted line which indicates the driving in limit).
5. Now sensors could be connected to TRi control box unit. pH & ACL sensors must then be calibrated
before using TRi PRO module (see chapter 4 / 'Calibrating pH & ACL sensors').
WARNING : Follow the color code of sensor's cables before plugging it onto TRi control box unit :
- BNC socket marked « pH » = pH sensor's cable (blue plug)
- BNC socket marked « ACL » = ACL sensor's cable (red plug)
