INSTALLER
32
The inlet fitting (A) of the HN2 neutralisation unit (the
lower fitting) must be connected to the boiler conden-
sate drain fitting using the flexible hose (C) supplied.
This condensate 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 boiler room’s condensate drain pit must be located
no more than 1.5 metres above the neutraliser.

All connecting hoses must be kept as straight and
as short 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.
MAINTENANCE
The neutralisation unit should be serviced at regular
intervals (at least once a year) or as needs require. The
frequency of servicing depends on the characteristics
of the system. When servicing the unit, always check
the level of the granulate. The minimum granulate level
is 15 cm below the top of the granulate box. The initial
charge of neutralisation product should be enough to last
at least one season of heating operation with maximum
condensate formation.
The easiest way to check the correct functioning of the
neutralisation unit is to use litmus papers for pH testing.
These are readily available from chemists' shops and
chemical suppliers. Treated condensate leaving the unit
must have a pH between 6.5 and 9. If limescale forms on
the surface of the neutralisation unit, replace the entire
granulate charge.
