Maintenance
Neutralisation device maintenance must be performed at
regular intervals and as required (minimum once per year).
The requirement for maintenance depends on the system
characteristics. For this purpose, the filling level of the dol-
omitic granules must be checked. The minimum filling level
is equal to 15 cm, starting from the upper edge of the box.
The first filling of neutralisation product is sufficient at least
for one heating season in the case of maximum formulation
of condensate.
The operation can be checked easily using the pH indica-
tor cards available commercially. They can be purchased
from any pharmacy or store selling chemical products. The
condensate that exits must have a pH value between 6.5
and 9. If any deposits are found on the surface of the neu-
tralisation device during maintenance, it is recommended
to replace the granulate.
