2.1 Intended use
The Vaillant condensed water pump is constructed using
state-of-the-art technology in accordance with the recog-
nised safety rules and regulations. Nevertheless, there is
still a risk of injury or death to the user or others or of
damage to the unit and other property in the event of
improper use or use for which it is not intended.
The ecoLEVEL condensed water pump is intended for use
only in conjunction with Vaillant system components in
which the condensed water is produced as a by-product of
operation. This includes all Vaillant condensing boilers.
The ecoLEVEL condensed water pump is only approved for
individual units up to 45 kW. The pump and all of its compo-
nents are designed for delivering condensed water from
heating installations. The introduction of rainwater into the
system as a result of the flue gas system is taken into
account in terms of the permitted volume, the composition,
and also the content of solids in the condensate.
This unit is not designed to be used by persons (including
children) with limited physical, mental or sensory capabili-
ties or by persons who do not have enough experience and/
or knowledge, unless they are supervised by a person who
is responsible for their safety or have been instructed by
him/her about how to use the unit.
Children must be supervised to ensure that they do not
play with the unit.

The condensed water pump is not suitable for the pumping
of other fluids or solid media. In particular, waste water of
all types, chemicals and emulsions that contain oil must not
be fed into the condensed water pump. Using the con-
densed water pump in vehicles is regarded as improper use.
Units that are not classed as vehicles are those that are
installed in a fixed and permanent location (known as "fixed
installation").
Any other use, or use beyond that specified, shall be con-
sidered improper use. Any direct commercial or industrial
use is also deemed to be improper. The manufacturer/sup-
plier is not liable for any claims or damage resulting from
improper use. The user alone bears the risk.
Intended use includes observance of the operating and
installation and maintenance instructions and all other
applicable documents, as well as adherence to the mainte-
nance and inspection conditions.

Once the installation and the hydraulic and electrical con-
nections are completed, the ecoLEVEL condensed water
pump is ready for operation. The green LED lights up. The
operation is self-regulating and does not require any fur-
ther manual control.
6.1 LED display of operating status or faults
On the front of the ecoLEVEL condensed water pump cas-
ing, there are two LEDs (¬fig. 6.1), items 1 and 2) which
indicate the operating status or faults of the ecoLEVEL
condensed water pump.

6.2 Faults
The ecoLEVEL condensed water pump can automatically
resolve short-term faults in the normal function sequence.
When the maximum permitted water level is reached, both
LEDs flash. If the water level cannot be reduced by pump-
ing, the red LED flashes. As a consequence, the safety cut-
out switch is triggered after approx. 10 seconds. A poten-
tial-free contact or the current circuit opens to switch off
the boiler.
If a corresponding connection to the boiler has been
installed, the boiler is switched off to prevent any further
condensed water from being formed.
6.3 Fault diagnostics and elimination
If the red LED flashes or remains lit for longer than
1 minute, there is a fault in the installation or a defect in
the pump.
