• Turn off your power pack then the filtration by cutting
off the main electricity supply in order to isolate the
installation.
• Close the isolating valves in the pipework.
• Remove the silver cover by pressing the sides and raising
it (
1
), then unscrew the four screws attaching the
original (empty) lower module to the power pack (
2
).
• Remove the empty module and present the pH Link or
Dual Link module to be installed (
3
).
•
Connect the ribbon cable from the pH Link or Dual Link
to the connector on the power pack (
4
).
• Put the pH Link or Dual Link module in position, replace
the four screws and replace the silver cover.
• Do not reconnect the electricity supply until the pH Link or Dual Link module, the sensor-holding POD Kit 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 power
packfrom the mains electricity supply and connecting the pH Link or Dual Link module.
2.3 Installing the POD Kit
The sensor-holding POD Kit is a single assembly including the flow rate detector (used by your appliance, see § 2.3.2), the
pH and ACL sensors and pH minus injection.
•
The cell bypass valves must always be open.
• The sensor-holding POD Kit must always be positioned on a horizontal pipe so that the sensors are vertical (
1
or
2
).
• The POD Kit 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 Kit must
be installed before it (
3
) (to take readings on unheated water).
• We recommend positioning the POD Kit more than 20 cm from an elbow in the pipe.
• The sensor cables must not be positioned near high voltage mains electricity cables.
