OPTION B: SPA FLOOR RETURN
This option allows you to direct part of the already filtered and heated water both via the return
nozzles and via the Spa floor drain.
The filtered water is only suctioned from the balance tank by the filter pump and is directed
toward the sand filter, the heating and the ozoniser or disinfection system, to then be directed
towards the Spa via the return nozzles and the Spa floor drain.
