MECHANICAL MEASURES:
Check the filter, the skimmer, the valves and the pipes are well connected to the pool. Do consider high water temperature will
involved more time for the filtering. Theoretic filtering time = Water volume / Filter system discharge (generally 8h/day with water
temperature of 21°C), (Ideal: 2h in the morning – 4h around midday – 2h in the afternoon). PLEASE RESPECT THE CONTINUOUS
WORKING PERIOD INDICATED IN THE FILTER MANUALS.
VACUUM CLEANER (MANUAL OR AUTOMATIC):
Only for pools with skimmer. Connect an hose extremity to the brush head and immerse it into the water to make it fill in. Connect the
other pipe extremity to the exhaustion adapter (TA) and place it above the skimmer basket. Switch on the filter in the FILTER position
and begin to clean the bottom. Pay special attention to areas with folds where dirt accumulates.
BOTTOM CLEANER VENTURY STYLE:
Connect a garden hose to the bottom cleaner join and introduce it into the pool. Open the tap until a normal pressure to make the
water flow out against the bottom of the pool, producing in that way an ascendant stream which leave the dirt into the filter (bag)
which is adjust on the bottom cleaner.
