NOTICE
It is normal for a few drops of water to escape from the
mechanical seal from time to time. This is especially true during
the break-in period.
Depending on the water quality and number of operating hours,
the mechanical seal can begin to leak.
If water leaks constantly, have the mechanical seal replaced
by a qualified technician.
NOTICE
We recommend first informing the swimming pool contractor if
there are irregularities.
