Electrical Connection - Pompes Guinard Loisirs IDRA N Mode D'emploi

Make sure the well flow is higher than required, to prevent the pump from running dry or from starting and
stopping more often than normal.
If the well water level fluctuates significantly, we recommend installing level electroprobe equipment.
To avoid ruining the motor power cable and level electroprobe cables, attach them to the discharge line with
clamps when lowering them into the well.
In the ,'5$0$7,& models, the geometrical height from the position of the pump to the highest point of the
installation should not exceed 0m  P  . See fig. 3.
5. Discharge line assembly
The pumps are supplied ready to be connected a 1" line. However, if the geometric height is considerable and the paths
are long and winding, we recommend using lines with a larger diameter, to avoid head loss due to friction as much as
possible and to obtain the best hydraulic performance possible.
Install a check valve on the outlet of the pump to prevent the line from emptying every time the pump stops.
The check valve is already included in the ,'5$0$7,& models. DO NOT ATTEMPT TO INSTALL ANOTHER VALVE.
Install the included expansion vessel (Kit Pres) at some point of the discharge line. See fig. 3.
If a plastic hose is chosen instead of a metallic line, make sure it can withstand the pressure provided by the pump. Prevent
the hose from becoming twisted because, in addition to preventing the desired flow, proper pump operation will be hindered.

Electrical connection

All electrical connections and splices should be performed by authorized professional installers.
The pump must be installed with a differential switch (1 fn = 30 mA). I∆n
The electrical installation must have a switch with at least a 3-mm opening between contacts. The pumps are
supplied with a cable.
To lengthen the electrical cable, use resin connection splices only. Pay special attention ensuring that the colors
of pump cables match those of the extension.
It is imperative to connect the ground cable (yellow-green color).
In the single-phase motors with external capacitor, connect the capacitor together with the protective panel to the
outside of the well.
Thermal protection must be provided by the user (in accordance with current installation rules).
For correct electrical connection, follow the diagrams in fig. 4 (external capacitor), 5 (internal capacitor) or
6 (three-phase).
7. Verifications prior to initial start-up
Make sure the mains frequency and voltage match the indications of the name plate.
Make sure the value of the capacitor is the same as described on the plate (single-phase version only).
Check that the pump is completely submerged. If the flow is less than expected, invert two phases of the power
supply in the protective panel (three-phase version only).
NEVER LET RUN THE PUMP DRY.
8. Start-up
If there is a line valve, open it completely.
Connect the power supply switch. Water will never flow at the end of the line immediately; if the path is long, wait a few minutes.
Check that the absorbed current is the same as marked on the name plate and adjust the thermal relay accordingly
(three-phase version only).
If the motor does not start or no water flows at the end of the line, try to find the anomaly using the troubleshooting guide
in point 10.
