readings.
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
HC LS.
®
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
of water.
3
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.

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.

6c. Installing and starting up the temperature probe
•
Always begin the calibration procedure with a calibration reset.
•
Please contact your reseller to configure the temperature probe.
1
Open the cover, connect the temperature probe to
the °C terminal using a cable gland (see section 3C
and 3D) and close the cover.
2
Configure the temperature probe in the service
menu. Follow the procedure shown here and contact
your installer.
3
The temperature value appears in the top-right
corner of the screen.

3
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.
Activation of the temperature probe gives access to
the Smart filtration mode.
6d. Installing and starting up a heat pump
•
Please contact your reseller for installation and configuration of a heat pump.
1
Open the cover, and plug the heat pump cable into terminal AUX4 using a cable gland (see paragraph 3C and 3D) and close the cover again.

6e. Installing and starting up the free chlorine option (amperometric sensor)
•
Always begin the calibration procedure with a calibration reset.
•
We recommend calibrating the free chlorine sensor with a high chlorine level: between 1ppm and 1.2ppm.
1
Open the cover and connect the
CL CHIP card to the CL slot (see
section 3C). The chlorine reading
and the Measures menu will be
displayed automatically to configure
the setpoint and carry out the
calibration.
2
Place the sensor in a bypass,
following the sensor instructions.
3
Connect the 3 cables of the floater
to the extension circuit board (see
section 3C).
4
Connect the 2 cables of the sensor
to the extension circuit board (see
section 3C).
