Ensures the non-corrosive and safe pH Value of over 6.5 as prescribed by
Mounting
MGK 130 - 300
The booster pump must be attached
certainly higher than the neutralization
to prevent condensate from flowing back
into the booster pump!
Danger of electric shock!
The booster pump favors an intensive
pH-regeneration.

The filter should be wall-mounted or floor-mounted, horizontal, at least 100 mm below
the condensate outlet of the condensing boiler.
MGK-2-390 - 630
The connection to the boiler must be backflow-safe. (See mounting-sketch and
observe the notes in the assembly instructions for the condensing boiler). In order to avoid
air bubbles, all connecting piping must be with a suitable slope over their entire length.
The condensate flows through the granules, neutralizing the acid (over pH 6,50; ac-
cording to Water Authority DWA-Worksheet A 251). The neutralised condensate can
damage neither the domestic nor the public sewer piping.
To ensure proper operation, the granules must be serviced once per year:
1. Unscrew the pipe connections and remove the filter from the brackets. Take
out the screens. In the case of type 03/04/08/BGN, loosen the hose clip and remove
the maintenance cover.
2. Flush out the Filter-sludge with a strong water-jet. Clotty granules should be loosened
with a wooden stick (e.g. Hammer-handle). Take care not to break the plexiglas
housing. Clotty granules do not affect the filter softening capacity.
Take care that the granules do not obstruct the inlet- and outlet – connections!
3. Check Granule Level! When the level of the granules been consumed by the acid
to below the minimum indicator (red label), the filter must be refilled. The original
filling lasts for at least one year.
4. Check the pH value using pH-indicator-paper or a suitable measuring device!
Values below pH 6.5 indicate an acid = highly corrosive condensate and the filter
must be refilled with fresh granules. For exact pH- measurement an electronic pH-
Meter must be used.
