The manually operated water softener HEH 9 softens heating fill water and top-up water. A water meter monitors the softener capacity. The system consists of flexible connection hoses, softener cartridge with exchange resin, sampling valve, a dosing point for the addition of GENO®-safe A and a water test kit for total hardness. Optional accessories are the GENO®-therm Basic filling device, a water meter with connection accessories and a blending housing. The water softener's exchange resin must be replaced when it has been depleted. The plastic design of the water softener HEH can be subjected to pressure of up to 10 bar. The nominal flow is 0.3 m3/h, the nominal capacity 18 °dH x m3 and the soft water capacity for raw water hardness 20 °dH x 900 litres.
Please note local installation directives, general guidelines and technical specifications. The installation site must ensure the water softener HEH 9's protection against chemicals, dyes, solvents, vapours and direct sunlight. For shut-off, a shut-off valve must exist upstream and downstream of water softener HEH. A water meter with roller counter must be installed downstream of the water softener HEH 9 to check soft water capacity. To control the pressure, we recommend a pressure gauge in the direct vicinity so that the pressure permitted for the heating system is not exceeded during filling/refilling.
