It is essenti al that the pool water balance is controlled and adjusted before installing the appliance. Making
sure that the pool water balance is correct from the very start will reduce the likelihood of encountering

Even though it is an automati c regulati on system, it is essenti al to carry out regular water analyses
to check the water balance parameters.
