6b. Installing and starting up the ORP option
•
Always begin the calibration procedure with a calibration reset.
1
Open the cover and connect the rX CHIP card to
the RX slot (see section 3C). The ORP reading and
the Measures menu will be displayed automatically,
to configure the setpoint and calibrate the probe.
2
Install the probe with its mount in the pipe, connect
the probe to the unit (see section 3D), and close the
cover.
•
The probe has a lifetime of 1 year. We
recommend calibrating it every month during the
season the pool is in use.

ORP probe calibration: Recommended every two
months during the pool season.

Calibration with buffer solutions. With reference
solution 465 mV. Follow the instructions that appear
on screen 3.
Setting the ORP level
The ORP level tells you the oxidation potential, i.e. the disinfectant capacity of the
water.
Setting the ORP set point is the last step in setting the AquaRite
To find the optimum ORP level for your pool, follow the steps below:
1
Start up the pool filtration system (the salt in the pool must be evenly dissolved).
2
Add chlorine to the swimming pool until it reaches 1 to 1.5 ppm. This level is
achieved with approximately 1 to 1.5 g/m
The pH level must vary between 7.2 and 7.5.
3
After 30 min. check that the level of free chlorine in the pool (manual DPD1 test
kit) is between 0.8 and 1.0 ppm.
Operation of the ORP module:
By default, when the ORP option is connected, the
electrolysis cell starts up as soon as the measured
ORP value falls below the setpoint.
Installing and preserving the ORP probe:
1
The ORP probe is «wet» packed and protected
by a plastic cap. The probes must always remain
wet. If the probes are allowed to dry, they will
be permanently unusable (not covered by the
warranty) and the ORP test kit will be ineffective.
2
Remove the ORP probe from its plastic protective
cap and set the cap aside for later use (wintering or
maintenance).

Manual calibration: Allows you to calibrate
the probes using 1 point (without solution) –
recommended only for adjusting small deviations in
readings.

3
Put the probe into the probe holder or double probe
holder (depending on the options ordered) and
tighten the probe mounts to ensure watertightness.
4 Check that the probes are watertight at startup.
Seal with Teflon, if required.
5
After installation, check that the probes are
constantly in contact with the water in the pool.
When the filtration pump is not running (even for
long periods), the water remaining in the circuit may
be sufficient to protect the probes.
i
The product (liquid chlorine, etc.) injection device
must be installed last on the water return line, after
any equipment (heater, cell, etc.). Seal with Teflon.
The default value is 700 mV.

5
Without taking the probe out of the water, use
the Up/Down arrows to adjust the measurement
displayed so that it coincides with the reference
value (photometer or other measuring instrument).
4
Look at the ORP value on the screen and enter it as the ORP set point.
5
The next day, check the free chlorine level (manual DPD1 test kit) and the ORP
level. Increase / reduce the setting, if required.
Remember to check all your water parameters at regular intervals (2-3 months) (see
table Chemical water balance) and adjust the ORP set point according to the steps
listed above.
