Condensate neutralisation unit
NEUTRALISATION UNIT TYPE N2
N2 neutralisation units are designed for systems with
boiler condensate drain pits located at a lower level
than the boiler condensate drain fitting. These neutra-
lisation units do not require any electrical connections.

The inlet fitting (A) of the N2 neutralisation unit (the lo-
wer 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).

The boiler room’s condensate drain pit must be
located at a lower level than the fitting (B) on the
neutralisation unit.
If it ever proves necessary to neutralise the condensate
that forms in the flue gas stack, connect the condensate
drain fittings of the boiler and flue gas stack together
using a ‘T’ union and connect the leg of the ‘T’ to the
inlet of the N2 or neutralisation unit.

Make sure that you tighten the hose clamps suffi-
ciently.

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 there-
fore prevent proper condensate discharge.
NEUTRALISATION UNIT TYPE HN2 (with pump)
HN2 neutralisation units are designed for systems with
boiler condensate drain pits located at a higher level
than the boiler condensate drain fitting.
The pump is controlled by an electrical level switch in
the HN2 neutralisation unit. Refer to the instructions
provided to connect these neutralisation units up elec-
trically. These units have an electrical protection rating
of IP44.
