APPENDIX 1 - TROUBLESHOOTING
Problem
Possible cause
Solution
Concentration of free Chlorine in
the pool is too low
The device is not working correctly
Check to see if an error message
is displayed on the control
panel screen, and refer to the
corresponding list.
The device remains off even though
it should be running
See above
The Redox sensor is badly
calibrated (EES Pro only)
Calibrate the Redox sensor
The Redox set point is not high
enough (EES Pro only)
Check that the Redox set point
is correct, modify the set point
if necessary. If the set point is
correct, check that this value
corresponds to the desired Chlorine
concentration (create a water
sample of the desired Chlorine
concentration and test using a
photometer)
Filtration run time is not long
enough
Check the filtration run time,
increase it if it is less than 10 h/day
The salt concentration is barely
within range
Measure the salt concentration and,
if necessary, adjust it so that it is
between 4.5 and 5.0 g/l
Scale is starting to build up on th e
electrodes
Inspect the electrodes and descale
if necessary
Free Chlorine stabiliser
(Isocyanuric acid) concentration is
too low
Measure the concentration of
Isocyanuric acid, this should be
between 30 and 50 ppm
The concentration of Phosphate in
the water is high
Check that the water's phosphate
concentration is less than 100 ppm.
Water is turning green, or brown
stains are appearing on the pool
walls and floor.
The concentration of free Chlorine
is too low
Check the concentration of free
Chlorine, correct if necessary.
The water contains too much
stabiliser
Measure the concentration of
Isocyanuric acid. Renew a fraction
of the pool water volume to bring
the stabiliser concentration back
below 50 ppm.
The water contains too much
dissolved metal (copper, iron,
manganese) (tbrown stains on
PVC waterproofing membranes)
Measure the concentration of
metals. Add a metal flocculent.
