REQUIREMENTS FOR SOURCE AND SINK MEDIA 

 

In order to ensure the Connect WP operates faultlessly for many years, we strongly recommend filling 
the two system circuits (AWN brine circuit and heating water charge circuit) with softened and 
desalinated water. This serves to protect against corrosion and contamination of the heat exchanger. 
The following limit values must be adhered to: 

 

pH value 

7.5-9 

Electrical conductivity 

100-500 µS/cm 

Total hardness 

4.5-8.5 dH 

Temperature

< 50% 

Phosphate (PO4) 

< 2 ppm 

Manganese (Mn)  < 0.05 ppm 

Iron (Fe) 

  < 0.3 ppm 

Alkalinity (HCO3) 

  70-300 ppm 

Chlorine ions (CI-) 

< 50 ppm 

Sulphate ions (S) 

< 50 ppm 

Sulphide ions (S) 

None 

Ammonia ions (NH4) 

None 

Silicon dioxide (SiO2) 

< 30 ppm
