2.2 Installing the TRi pH or TRi PRO module
•
Turn off your Zodiac TRi salt chlorina

tor and then filtration by cutting off the
main electricity supply in order to iso

•
Close the isolating valves in the pipe

work.
•
Remove the silver cover by pressing the
sides and raising it, then unscrew the
four screws attaching the original (emp
-
ty) lower module to the main unit.
•
Remove the empty module and offer up
the TRi pH or TRi PRO module.
•
Connect the ribbon cable from the TRi
pH or TRi PRO to the connector on the
TRi power pack.
•
Put the TRi pH or TRi PRO module in po
-
sition, replace the four screws and re
-
place the silver cover.
•
Do not reconnect the electricity supply until the TRi pH or TRi PRO module, the sensor-holding POD and the pH
minus injection pipe have been installed (see § 2.3.3).
•
Always wait 2 minutes, particularly when performing any technical work, between disconnecting the TRi from
the mains electricity supply and connecting the TRi pH or TRi PRO module.
2.3 Installing the POD
The sensor-holding POD is a single assembly including the flow rate detector (used by your TRi chlorinator, see § 2.3.2),
the pH and ACL sensors and pH minus injection.
•
The TRi unit bypass valves must always be open.
•
The sensor-holding POD must always be positioned on a horizontal pipe so that the sensors are vertical.
•
The POD must be the first unit fitted after the pool filter.
•
If the pool is fitted with a heating system (heat pump, heat exchanger, electric heater, etc.), the POD must be
installed before it (to take readings on unheated water).
•
We recommend positioning the POD more than 20 cm from an elbow in the pipe.
•
The sensor cables must not be positioned near high voltage mains electricity cables.

A badly-installed sensor may give false readings and cause inappropriate operation of the TRi unit. Neither the
manufacturer nor the unit shall be liable in this event.
