Storing in winter
At the end of the summer season, disconnect the tubes; remove water from the filter by operating the tap. For the filter and the
pump, you have to undo the purge screw. Open the filter and check the sand. Check the state of the sand in the monobloc (it must
not be sticky or stuck together) and clean it. The monobloc placed in the open air must be protected against freezing during the
winter.
Damage caused by freezing is not covered by the guarantee.
Maintenance suggestions
The visible impurities are eliminated by the monobloc. What the monobloc does not eliminate are the algae, bacteria and other
microorganisms that cloud the water, affect the water purity and hygiene. To prevent their appearance and eliminate them, specific
products exist for the water maintenance, with a correct dose do not cause any problems to the bathers guaranteeing a pool
perfectly disinfected.
The filtration cycles (2 x 4/5 hours a day) and the regular counter washing of the filter (2 to 3 minutes) at least once a day
as well as the use of the pool floor cleaner, are the necessary conditions for the good maintenance of your pool.
Ask your usual salesperson for advice.
