• If there is a large amount of air in the suction line – it may happen that the pump switcher again dis-
plays this fault message – fill the pump housing again over the filling nozzle and repeat the procedure
described above;
-
Depending on the system configuration, it takes a long time for the air to be completely pumped
out of the suction line and the Conel Flow Rain-Champion to operate in normal operating mode.
•
Allow possible air inclusions to escape from the suction line until a continuous jet of water flows out
of the sampling point (may take a few minutes);
• Close the picking point again;
•
The pump continues to run until the pump switching machine finally shuts down the pump with an
integrated follow-up time.
• To vent the entire piping system, slowly open each extraction point in the system and allow the air
pockets to escape until a continuous jet of water flows out of the sampling point;
• Now the Conel Flow Rain-Champion is in automatic operation and automatically controls the supply,
with rain/needs-oriented with drinking water, the collection points.
• At each water collection point involved, add the „No drinking water“

Remedy
A polluted
Suction line
1. Pump blocked.
2. Pump switching
machine is not working
correctly.
3. Picking points do not
close completely
¾
Check the suction line for contamination
- clean and rinse if necessary. Remove the
pump, remove the blocker ground, clean it.
¾
Remove and clean the pump switcher.
¾
Drain the contaminated water completely and
rinse with clean water until any residues are
removed.

Contact the manufacturer
(see Chapter 1.4

Eliminate leaks.
If you notice malfunctions, disconnect the Conel Flow Rain-Champion from the electrical power supply
and secure it again against unauthorized and unintentional ones and observe the notes in the trouble-
shooting chapter (see chapter 10 Troubleshooting for details).

VENT PUMP HOUSING:
Note:
• The operation of the pump with leaks in the suction line or its piping can cause
damage to the pump;
• Avoid dry running of the pump - can cause damage to the pump;
• To ensure that the water column in the suction line does not tear off, we
recommend the use of a return preventer;
• The pump independently sucks the air out of the suction tube – after that the
liquid is conveyed;
Drain pump housing
