APPENDIX 1 - TROUBLESHOOTING

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