The pressure line establishes the connection to the on-site installation and regulates with the pump
switcher the pressure - and flow-dependent supply with regen- or drinking water.
• For the connection of the pressure line, we recommend a dimension-appropriate 1“ inner diameter
tank hose with the required connections and an additional ball tap, thus:
- can be compensated for on-site assembly tolerances;
- reduce possible vibration and noise transmissions;
- the pressure line can be shut off at any time;
- required work am Conel Flow Rain-Champion can be carried out with less effort.
•
Connect the tank hose connector (1“ IG) to the 1“ AG of the pump switcher and ensure a fixed and
leak-free connection (see Figure 8.5.1);
• If you are not using an armored hose to connect the Conel Flow Rain-Champion, make sure that the
piping and connection are exactly in the flight to the Conel Flow Rain-Champion connector and that
there are no tensions – leakage possible;
•
To fix the piping, use pipe clamps.

CONNECTION OF THE EMERGENCY OVERFLOW
In the unlikely event that too much drinking water is discharged into the Conel Flow Rain-Champion and
overflow, this amount of water can be discharged in an orderly manner via the emergency overflow of
the Conel Flow Rain-Champion into the public sewer network or into a lifting system.
•
In order to ensure a proper operation of the emergency overflow if necessary, the following measu
-
res are mandatory:
-
Connect the emergency overflow of the Conel Flow Rain-Champion (DN70) at least with a DN
70 pipe (drain) and initiate it into the public channel or a system.
-
Make sure that the flow is a vertical drop distance of min. 50cm before a elbow is placed - better
flow in the drop;
- We recommend the installation of a dimension-appropriate siphon as an odour closure to the
sewer network.
NOTE:
• The operation of a Conel Flow Rain-Champion requires a room with integra-
ted ground runoff on the construction side.
•
If the device is installed below the backlog level (x), the overflow must be
discharged into a lifting system that discharges the water above the backlog
plane into the channel via a pipe loop. Make sure that the lifting system is
sufficiently dimensioned with a conveying capacity of at least 3m3/h.
(x) Backlog level:
The level to which an overloaded sewer network can accu-
mulate – usually corresponds to the respective road level, in order to be sure,
please contact the responsible building authority.

INSTALLATION OF THE IMMERSION PRESSURE PROBE IN THE STORAGE TANK
The immersion pressure probe monitors the water level in the storage tank and shows it using the level
indicator. If necessary, the TopRain‘s water supply is switched from rainwater to drinking water, thereby
ensuring a continuous water supply for consumers.
• Carefully lower the level sensor (do not drop it) to the bottom of the rainwater storage tank. The
stainless steel sensor should lie horizontally on the bottom of the container.
• Pull the excess sensor cable through the conduit into the house.
• Make sure that no water can enter the end of the sensor cable!
• Only remove the adhesive tape at the end of the sensor cable after it has been laid!
•
Measure the maximum water depth of the rainwater storage tank from the ground to the overflow,
e.g. with a folding rule, this is necessary for the later calibration of the control.
