3.6. Operation of the filtration pump and verification of its character-
istics
Operation
:
The filtration of an individual swimming pool operates between 10 to 15 hours per 24 hours during daytime de-
pending on the water temperature during the period from May to September.
Usage indicates that the filtration time must be diurnal and equal in hours to the temperature divided by 2.
For example, for a swimming pool water temperature of 24 ° C, the filtration time must be equal to 12 hours
daytime.
The solar heating system will bypass the filtration flow, but it is not intended to activate the filtration.
Normally during the period of use of the swimming pool, the ambient temperature is higher than the tempera-
ture of the swimming pool, therefore the filtration flow is systematically bypassed in the panels to recover the
available energy. The system will automatically divert the filtration flow to the solar panels when the latter are
hotter than the temperature of the swimming pool, and within the maximum limit of the defined basin tempera-
ture.
Checking the characteristics of the filtration pump:
CAUTION
It is imperative to ensure that the filtration pump has a sufficient head to ensure the nominal
flow rate necessary for the filtration of the swimming pool and for the correct irrigation of the
solar panels.

Make sure to regularly maintain your sand filter so that it does not clog abnormally and that its pressure drop
remains compatible with the correct operation of the solar installation.
