Checking and treating the heating
water/filling and supplementary water
Caution.
Risk of material damage due to poor-qual-
ity heating water
▶
Ensure that the heating water is of suffi-
cient quality.
▶
Before filling or topping up the installation, check the
quality of the heating water.
Checking the quality of the heating water
▶
Remove a little water from the heating circuit.
▶
Check the appearance of the heating water.
▶
If you ascertain that it contains sedimentary materials,
you must desludge the installation.
▶
Use a magnetic rod to check whether it contains mag-
netite (iron oxide).
▶
If you ascertain that it contains magnetite, clean the in-
stallation and apply suitable corrosion-inhibition meas-
ures, or fit a magnetic filter.
▶
Check the pH value of the removed water at 25 °C.
▶
If the value is below 8.2 or above 10.0, clean the installa-
tion and treat the heating water.
▶
Ensure that oxygen cannot get into the heating water.
Checking the filling and supplementary water
▶
Before filling the installation, measure the hardness of the
filling and supplementary water.
