1 General information
The neutralisation device provides neutralisation of the
condensed water from boilers and/or flue pipe systems
made of stainless steel, plastic and ceramic.
The condensed water from the condensing unit is fed
into a vessel. In the vessel there is neutralising medium
which lifts the pH value of the condensed water to a
neutral level. The neutralisation medium can be replaced
via a removable cover.
The neutralised condensed water can be fed into the
drainage system.
Only for units with Part No.: 301374:
A feed pump pumps the neutralised condensed water
through a drain hose, controlled by the level of water,
over a height difference of up to 2 metres. It can then be
directed into the sewage system from this location.
The operating conditions of the unit are displayed. In the
event of a fault the boiler is temporarily switched off via
an error signalling line which is connected directly into
the System ProE Switching Field of the condensing boil-
er until the fault is resolved. This prevents condensed
water from coming out of the unit into the room.
