Water treatment

Poolex heat pumps for swimming pools can be used with all types of water treatment systems.
Nevertheless, it is essential that the treatment system (chlorine, pH, bromine and/or salt chlorina-
tor metering pumps) is installed after the heat pump in the hydraulic circuit.
To avoid any deterioration to the heat pump, the water's pH must be maintained between
6.9 and 8.0.
