The LM2 functions only operate during the filtering process.
For an outdoor pool,
run the pump + chlorination system for 6 to 8 hours
per day. To reduce the effect of UV reduction of chlorine it is preferable to
run it at the end of the day or early in the morning when it is cooler.
During very hot periods,
it can be necessary to increase operation time
to approximately 10 hours per day.
If the filtering system has to be in operation for more than 10 hours per
day (in particular during the period when the temperature rises, when
there is a heating system), it can be necessary to reduce the production
level (button E) so as to avoid over-chlorinating the pool.
In winter,
operation time should be reduced to 2-3 hours or the system
is stopped completely and the pool is closed down for the winter,
so as to prolong the life-span of the electrodes.
For indoor or covered pools,
these standard times should be heavily
reduced or the production of chlorine lowered to avoid excessive chlorine
levels.
To be sure that your chlorinator is operating at its optimum,
the water balance must be regularly checked and maintained :
Salinity
4 kg of salt per m
3
pH
7.2 to 7.6
Chlorine stabiliser
40 to 75 g per m
3
TAC, total alkalinity
8 to 12° (French)
Free chlorine
1.5 to 3 ppm
TH
10 to 30° (French)
You can modify this by changing the operation time or varying the hourly
production (button E).
From time to time extra salt is necessary. The best times are just before
the summer or when you start up the system after a prolonged stoppage.
> First of all you should analyse the salt level.
> Turn off the chlorinator before adding the salt.
> Add boiled salt at 99.9% to attain a concentration level of 4 g/litre.
> A bag of 25 kg of salt increases the concentration level by 0.5 g/litre
for a pool of 50 m
3
.
> Add a maximum of 2 bags of 25 kg at a time.
> For the salt directly into the swimming pool and not into the skimmers.
> Run the filtering system for 4 or 6 hours to disperse the salt,
but 24 hours are necessary for it to be completely dissolved.
> Repeat the operation if you have not obtained the ideal level
of concentration.
Only now can one restart the chlorinator.
