Saci pumps Optima 25 Manuel D'installation Et D'entretien page 21

Under no circumstances should chlorine tablets be placed in the pre-filter basket.
The special key that is supplied to OPEN the pre-filter cover, should never be employed to close it.
When there is a frost risk, or when the pump is to remain off for any significant length of time, then it should
be emptied. This is accomplished by removing the two emptying plugs on the lower part of the pump body.
Apart from what has been stated above, our pumps do not require any other maintenance operations since the
bearings have been dimensioned and lubricated for life.
