This acidic cleaning solution can be bought from your reseller or you can make it up yourself by mixing 1 volume
of acid with 9 volumes of clean water in a suitable container. ALWAYS ADD ACID TO WATER, NEVER THE OTHER
WAY AROUND!
•
Always clean the sensor before carrying out the calibration procedure.
•
During cleaning, NEVER WIPE THE SENSOR WITH A CLOTH but shake it gently to remove excess rinse water.
4.2 Wintering
• Rinse the peristaltic pipe by pumping clean water instead of pH minus solution, using the “TEST DOSAGE” function (see
§ 3.6.1).
• Unscrew the POD sensors (disconnect their BNC cable beforehand). Place them in their original protective caps or in
a container filled with tap water.
•
If necessary close the POD holes using the threaded stops.
NEVER leave a sensor to dry and/or exposed to the risk of frost, which would permanently damage it.
5. Troubleshooting
Message
Causes
Solutions
PH LOW
The measured 0.8 PH units or more below the set
point
Check the pH in the pool
Check the set point
Calibrate or replace the pH sensor
The pH sensor is dirty, out of calibration or not
working
Clean and calibrate the sensor
Replace the pH7.5 buffer solution if necessary
The pool size setting is too large
Check the selected pool size
PH ERROR
pH adjustment has performed 5 cycles without
reaching its set point (> 10 hours)
Check the pH in the pool
Calibrate or replace the pH sensor
The pH minus container is empty
Replace the container
The peristaltic pump is not primed
Test the peristaltic pump
The pH sensor is dirty, out of calibration or not
working
Clean and calibrate the sensor
Replace the pH7.5 buffer solution if necessary
The pool size setting is too small
Check the selected pool size
The peristaltic pump has not been operated for a
total of more than 72 hours
The pH in the pool does not need to be corrected
ACL HIGH
The measured Redox potential is more than 150
mV above the set point (the chlorine level may be
excessive)
Clean and calibrate the sensors
Wait until the error message disappears (no
chlorine production)
The pH is too low
Make sure that the stabiliser is lower than 30
ppm
Reduce the ACL set point
Make sure that the water's alkalinity level is OK
(well and rain water prohibited)
ACL ERROR
The ACL regulation authorised chlorine production
for a total of over 30 hours without waiting for the
ACL set point
Check the pH in the pool
Clean and calibrate the sensors
Replace the buffer solutions if necessary
Replace the sensors
Use "Boost" mode if necessary
The appliance has not produced any chlorine for a
total of over 30 hours
Check the pH in the pool
Clean and calibrate the sensors
Replace the buffer solutions if necessary
Replace the sensors
