5.3.2 Filling the heating installation
Caution.
Risk of material damage due to heating
water that is extremely calciferous or cor-
rosive or contaminated by chemicals.
Unsuitable tap water damages the seals
and diaphragms, blocks components in the
product and heating installation through
which the water flows and causes noise.
▶
Only fill the heating installation with suit-
able heating water.
▶
In case of doubt, ask a competent person
for details.
1. Ask a competent person where the filling cock is loc-
ated.
2. Connect the filling cock to a hot water supply in the way
you were told by the competent person.
