indoors. Afterwards, depending on the extent of clogging of the filter, the user will adapt the interval based

A drop in the flow rate from massage jets located in pump 1 zones is indicative that dirt has built up on the
filter cartridges and that they require cleaning.
Removal/ replacement of the filter cartridges:
• Stop pump 1 (filtration/ massage) if it is running.
• Pull the outer skimmer frame that houses the weir
upwards to release and remove the weir.
• Remove the basket by sliding it horizontally towards
the interior of the spa. The cartridge(s) will now be
visible.
• Unscrew and remove the cartridge(s).
• Perform these steps in the reverse order to replace
the clean cartridges.

Cleaning the filter cartridges:

Steep the cartridges in a 25% solution of AQUAFILTRE for 12 hours.
Remove the cartridge and rinse them abundantly with a jet of water to remove all trace of residue (do not
use a high pressure water jet). After allowing the cartridges to dry, brush them gently with a hard bristle
brush, then store in a dry place for future use.

The ozonator should be replaced every 3 to 4 years, depending on the frequency of use and bather load.
Although bubbles will continue to be expelled at the Ozone outlet nozzle, they will not have any disinfectant
effect if the ozonator is not replaced when necessary.
