3.1 Calibration procedure
The sensor must be calibrated when your pH Perfect is fi rst installed and ideally every two months
there after to obtain the best operating conditions.
- Calibration must be done each time your pool is restarted at the beginning of the season.
- The calibration procedure is carried out when fi ltration is stopped thanks to its double supply (the
appliance remains powered on). Before calibrating, stop fi ltration and close the valves so as to isolate
the pH sensor holder from fl owing water.
Procedure:
1. Fill fl ask n°2 with
clean water
(tap water).
2. Undo the sensor
holder and remove
the sensor from the
pipe.
3. Rinse the sensor in
fl ask n°2 (water).
Then shake gently
to remove excess
water.
4. Immerse the sensor
in fl ask n°1 (pH 7).

5. Keep the “CAL/Enter”
button pressed for more
than 5 seconds until
“Calibration” appears on the
LCD screen (5a).
Press the “CAL/Enter” button
again as indicated on the
screen for calibration on pH7
(5b).
an automatic progression bar
then appears (5c). Keep the
sensor immersed in the buffer
solution for 30 seconds.
6. After 30 seconds, the
appliance indicates the
measurement reliability of
the sensor expressed as a
percentage.
7. After 30 seconds, the
appliance indicates the
measurement reliability of
the sensor expressed as a
percentage.
8. Immerse the sensor in fl ask
n°3 (pH 4).

9. Press the “CAL/Enter”
button to go to calibration
on pH4. Press the “CAL/
Enter” button again as
indicated on the screen (9a).
an automatic progression bar
then appears (9b).
Keep the sensor immersed
in the buffer solution for 30
seconds.
10. After 30 seconds, the
appliance indicates the
measurement reliability of
the sensor expressed as a
percentage.
E.g.: 100% with a new sensor;
if < 25%, see chapter 8.
11. Rinse the sensor in clean
water, then shake gently
to remove excess water
and replace it in its sensor
holder (it must not touch the
pipe).
12. To fi nish calibration, press
the “CAL” button.
The instrument will return
to measuring mode.
• Once the calibration is complete, your pH Perfect is ready to regulate your pool automatically.
• If the pool pH is very far from the appliance set point (7.4 pH by default), pause the overdose safety
for 24 or 48 hours (see paragraph 4.6).
> The pH Perfect peristaltic pump is self-starting. However, it is possible to operate it manually by
keeping the ”
p
“ Navigation button pressed.
The peristaltic pump will then inject corrective solution as long as the button is pressed.
