7 Start-up
Once the ecoLEVEL condensate pump has been
mechanically and electrically installed, it is ready for
operation. The green LED lights up.
Note!
Once the pump has been installed and put into
service, operation is self-regulating and does
not require further attendance.

Display of operating status

On the front edge of the housing there are two integrat-
ed diodes which indicate the operating status of the
ecoLEVEL condensate pump.
The green LED signals the following statuses:
Green LED Red LED Meaning
Lights up Off Pump has 230 V mains voltage supply
Pump is operating and pumping out
Flashes Off
condensate
If the red LED lights up or flashes, a malfunc-
tion has occurred. See section 9.
8 Maintenance
Danger!
Risk of fatal electric shock from touching live
connections. Always switch off the power sup-
ply to the pump and boiler first. You may only
proceed with the maintenance once this has
been done.
• Make sure that the inflow and outflow are unobstruct-
ed.
• Remove the cover from the pump and inspect the con-
densate reservoir for contamination. If necessary,
clean the condensate reservoir with warm water and a
mild cleaning agent.
• Disassemble the non-return valve and clean it under
running water.
• Inspect the feed and discharge hoses and clean them
if necessary.
• In order to ensure an unobstructed flow, make sure
that the hoses are not kinked.
Note!
Maintenance on the pump can be scheduled to
coincide with the maintenance intervals for the
boiler. The pump should be serviced at least
once a year.

Problems

The ecoLEVEL condensate pump can rectify temporary
faults during normal operation by itself. The red LED sig-
nals the following operating conditions:
Green LED Red LED Meaning
The maximum water level in the pump
Flashes Lights up has been exceeded.
The container is pumped out.
The pump remains in an idle state for
Flashes Flashes a defined period, then starts up again
automatically.
If the LED lights up or flashes, the water level has
exceeded the maximum level and the overflow switch
has been triggered. Either a zero-potential contact or
the circuit is opened in order to switch off the boiler.
If the required connection to the boiler has been
installed, it will be switched off in order to prevent the
further accumulation of condensate.

Fault diagnosis

If the red LED lights up or flashes for a lengthy period,
there is a fault in the installation or a defect in the
pump. Check the following points when troubleshooting:
Cause
Pump is not discharging
condensate:
Runout hose is kinked
Motor blocked
Motor is defective
Pump not being filled
Water guage float is
blocked
Installation and maintenance manual ecoLEVEL 0020010507_02
Troubleshooting
Remove the kink
Visually inspect the feed area: look
for foreign objects and remove if
found
Replace the condensate pump
Check the position of the hose,
inspect for blockage, make sure it
is properly attached to the pump,
correct the problem if found
Ensure the float can move freely
