2.1 Preparing the pool

2.1.1 Water balance
It is essential that the pool water balance is controlled and adjusted before installing the appliance. Making sure pool
water balance is correct from the start will reduce the likelihood of problems occurring during the first days of operation
or during the pool usage season.
Even though it is an automatic regulation system, it is essential to carry out regular water analyses to check the
water balance parameters.
