6. CONNECTING AND CONFIGURING PERIPHERALS
Installing and starting up the pH option
6a.
•
Always begin the calibration procedure with a calibration reset.
1 Open the cover and connect the pH CHIP card to
the PH slot (see section 3C). The pH reading and
the Measures menu will be displayed automatically,
to configure the setpoint and carry out the
calibration.
2
Connect the dosing pump to the pH terminal using
a cable gland (see section 3C and 3D) and close
the cover.
3
Install the probe with its mount in the pipe and
connect the probe to the unit (see section 3D).
•
Follow the instructions for the pH pump to inject the
liquid.
• The probe has a lifetime of 1 year. We
recommend calibrating it every month during the
season the pool is in use.
Connecting the pH dosing pump
1
Connect the suction strainer: insert the
(transparent) PVC suction tube all the way into the
conical connector of the suction strainer, tighten the
clamping nut and position the suction strainer in the
bottom of the container holding the chemical to be
dosed.
2
Connect the suction and delivery tubes: loosen
the pump clamping nuts, insert the (transparent)
PVC suction tube on the left and the (opaque) PE
The use of dry acid such as sodium bisulfate to adjust the pH of the swimming pool is not recommended, especially in arid regions where pool water is subject to
significant evaporation and is not commonly diluted with mains water. Dry acid can cause a build-up of by-products that can damage your chlorinator.

pH probe calibration: Recommended once a

Calibration using buffer solutions (buffer
solutions pH7 / pH10 / neutral). Follow the
instructions that appear on screen 3.
delivery tube on the right all the way into the conical
connector, and tighten the clamping nut.
3
Connect the injection valve: loosen the nut, insert
the (opaque) PE delivery tube all the way into the
conical connector, and tighten the clamping nut.
Screw the valve on to the mount provided on the
cell using Teflon tape.
Operation of pH corrector dosing pump:
The pump starts up depending on the setpoint
entered in the menu Measures - Setpoints - acid
pH (setpoint < water pH). By default, the maximum
dosing time is 120 minutes to avoid acidification of
the water (AL3). The proportional method is used
for injection: 10 minutes ON (variable depending
on the difference between the measured value and
the setpoint) + 5 minutes OFF (fixed). Both acid
and alkali can be dosed (contact your installer). The
pump is equipped with an on/off switch.
•
The Santoprene tube of the peristaltic pump has
a lifetime of 2 years. We recommend changing it
once a year.
Installing and preserving the pH probe:
1 The pH probe is "wet" packed and protected by
a plastic cap. The probes must always remain

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

Only use spare parts supplied by Hayward brands
wet. If the probes are allowed to dry, they will
be permanently unusable (not covered by the
warranty) and the pH test kit will be ineffective.
2
Remove the pH probe from its protective plastic
cap and set the cap aside for later use (wintering or
maintenance).
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 pool water. When
the filtration pump is not running (even for long
periods), the water remaining in the pipes is
sufficient to protect the probes.
i
The sanitization products (acid, etc.) must be
injected last on the water return line, after any
equipment (heater, cell, etc.). Seal with Teflon.
i
All types of acid (sulphuric, hydrochloric or a blend)
are compatible. We recommend using sulphuric
acid.
The default value is 7.2.

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).
