Overproduction
This alert is generally caused by an excessive
amount of salt in the pool or an increase of the
water temperature.
To avoid having an excess current damage the
cell and the control relays, the device cuts off
production as soon as such a situation is
detected.
Overproduction occurs mostly at the moment salt
is added to the pool when the device is started
before the salt is completely diluted.
Check the salt ratio ; if the ratio exceeds 5g/l, the
water should be drained and then the pool should
be filled until a salt ratio less than or equal to 5g/l
is obtained.
Underproduction
To avoid damaging the cell plates during an
operation with not enough salt, the device is
equipped with a detection device which stops the
treatment as soon as there is a lack of salt.
Check the salt ratio ; if the ratio is less than
2.5g/l (2500ppm),
salt has to be added and
production may be restarted only when the salt is
completely diluted.
If the salt ratio is correct, then either the cell is
scaled or it is worn out. Consequently, the cell
should be dismounted and the state of the plates
checked. If necessary, descale it (cf
Cleaning the
cell
).
In
Automatic mode
(thermoregulated) and if

could not produce throughout the
required time despite forced operation, the device signals underproduction by flashing the
indicator light. In this case, the daily filtration time should be increased.
Since water conductivity decreases with temperature, the chlorine production decreases when the
water cools. This phenomenon is taken advantage of to limit production in winter when the amount of
chlorine needed to disinfect becomes very low.
PH REGULATION
PH INDICATOR
Indicator light
⊳
When the left indicator light is lit, it
means that the water’s pH is less
than the setpoint value : The
dosing pump is stopped.
Indicator light
When the central indicator light is
lit, the water’s pH is equal to the
setpoint value : The dosing pump
is stopped.
Indicator light
When the right indicator light is lit,
the water’s pH is greater than the
setpoint value : The dosing pump
is running.
PH SETPOINT
The rotary switch allows selecting one of the four setpoint values :
7.0 / 7.2 / 7.4 / 7.6
This value defines the threshold above which the pump starts running to add acid to the
pool.
OVERDOSE INDICATOR LIGHT
To reduce the risk of overdose caused by a possible pH measurement error,
Limpido EZ

inhibits the pump from running if the pH is not corrected within 3h. Thus, the maximum
volume injected in 24h is limited to 2.7 litres.
To cancel an overproduction fault, it is necessary to stop and then
restart the device.
