Note!
If a second hose is to be connected, remove the
plug from the second feed opening (4) and con-
nect the additional hose as shown above.
• Put the cover back onto the ecoLEVEL condensate
pump from above.
5.2 Connecting and laying the discharge hose
• Push the discharge hose onto the removed non-return
valve as far as it will go.
• Insert the non-return valve back into the cover, and
lock it into place by rotating it a quarter turn to the
right (clockwise).
Laying the discharge hose:
The pump‘s discharge hose should be connected to the
building‘s waste water system.
• Guide the discharge hose directly from the pump far
enough upwards so that the height difference between
the pump‘s outflow and the drainage point can be
compensated for, and so that a slope in the hose can
be created between the deflection point and the drain-
age point when the hose is laid.
Caution!
Observe the pump‘s maximum delivery height
of 4 m!
• Then lay the discharge hose with a constant slope
down to the drainage point.
• Position the discharge hose with a U-shape at the
highest point to prevent backflow.

5.3 Connecting to the boiler
Using the feed hose supplied, the ecoLEVEL condensate
pump can be connected to the siphon of any Vaillant
condensing gas heating appliance.
• If the condensate drainage hose on the boiler is long
enough, it can be connected directly to the pump (see
Sec. 5.1).
If the hose on the boiler is too short, you can replace it
with the feed hose supplied.
• Connect the feed hose to the boiler‘s condensate out-
let.
• Connect the feed hose to the ecoLEVEL condensate
pump as shown in Fig. 5.1.
