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 dolomitic gran-
ules 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 indicator boards 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 neutralisation device during maintenance, it is recommended to replace the granulate.
The inlet fitting (A) of the N2 neutralisation unit (the lower
fitting) must be connected to the boiler condensate drain
using the flexible hose (C) supplied with the unit. This con-
densate drain hose is specially made to prevent combustion
fumes escaping into the atmosphere.
The outlet fitting (B) of the neutralisation unit (the top fitting)
must be connected to the boiler room’s waste water drain pit
using another section of flexible hose (not supplied).
IMPORTANT
The condensate drain of the central boiler should not be
more than 1.5 m higher than the neutralisation unit .
b
The connection pipes used must be as short and
straight as possible. Any curves or sharp bends can
lead to the hoses becoming clogged and can therefore
prevent proper condensate discharge.
Hoses should also be fixed to the floor and suitably
protected whenever possible.
