9.4 Water Quality Requirements
The ground water should not contain any substances that could
form deposits. The limit values for iron (< 0.2 mg/l) and manga-
nese (< 0.1 mg/l) must be adhered to prevent iron ochre sedi-
mentation in the heat pump system.
The use of surface water or water containing salt is not permissi-
ble. Your local water utility can provide you with general informa-
tion regarding the possible use of ground water. Water analyses
are carried out by specially-equipped laboratories.
It is not necessary to carry out a water analysis with regard to
evaporator corrosion if the annual mean temperature of the
ground water does not exceed
13 °C). In this case, the limit values for iron and manganese must
be adhered to (iron ochre sedimentation).

mentally-relevant requirements regarding the recovery, recycling
