During the first use, you should wash the filter (check the filer system maintenance). Filtering is a mechanical treatment that allows cleaning the pool water by
means of eliminating the impurities and contaminating particles. The hydraulic circuit and water purifying group is an essential element for the optimal operation
of the filtering system. The filtering system should be coherent: The filter dimensions should be proportionate to the volume of water in the pool and to the pump
performance. The filtering is not anti-bacteria Therefore, you should add a product (or a system) for disinfection of the water.
FILTERING TIME:
During the period of use of the pool kit, the filtering system should be used every day, for sufficient time to guarantee a complete renovation of the entire volume
of water. Theoretically, this the calculation:
(Water Temp / 2) = equals the filtering hours
Often, it is more practical to filter 4 hours before and 4 hours after use.
We do not recommend intermittent operation (stopping and starting every hour)
because not all the water volume will be renovated.
WATER TEMPERATURE FILTERING TIME FOR ONE DAY
15 to 18°C
19 to 21°C
22 to 25°C
26 to 28°C
28 to 30°C
+ than 30°C
Whichever is your filtering system, you will need to chemically treat the pool water to destroy the bacteria and the micro-bodies and to avoid
development of algae.
Several sterilization products can be used, like chloride, bromine, oxygen, etc. Request the assessment of a pool treatment product sales person to take a decision.
First, you have to verify the pH level using an analysis kit. Pay attention that the test bottles are only valid for one year.
The ideal level is between 7.2 and 7.4 of pH and 1.5 regarding CHLORIDE. Rectify this level using pH correctors (increasers or reducers). The quantity of product is
proportional to the cubic meters of your pools. To treat your pool, check the indications appearing on the product you have chosen for your pool.
pH (potential hydrogen) You should always maintain the water pH between 7.2 and 7.4 because below these values the water becomes corrosive (due to acidity)
and rapidly deteriorates the metal parts of your pool. Above these values the water is basic and greatly reduces the action of treatment.
Never introduce chlorine tablets directly into the pool. The liner would be «burnt».
