b) Electrical connection:
1.
Remove the lid from the junction box by loosening the three crosshead screws on the top.
2.
Loosen the two screws from the drawing shutdown system until the upper section slides freely and allows a power cable to
be fed through.
3.
Ensure that the power cable used is not connected to the mains.
4.
Thread the cable into-the rubber sheath of the cable gland, then through the drawing shutdown system.
5.
Connect it up according to the diagram below:
- The green and yellow wire should be connected to the terminal Marked:
- The blue wire should be connected to the terminal marked N.
- The red wire should be connected to the terminal marked L.
6.
Ensure that all the wires are securely attached to the terminals.
7.
Retighten the cord anchorage device, ensuring that the connector is resting on the power cable sheath and not on the wires.
8.
Replace the lid on the junction box by tightening up the crosshead screws.
9.
Connect the power cable to the mains
4) CONNECTING THE SUCTION HOSE
When assembling, all connections should be sealed with Teflon to ensure that complete sealing is achieved.
For connections fitted with flat or O-ring type seals, it is not necessary to add Teflon.
Check periodically that the seals are sound. The suction hose should be a minimum of 25mm diameter and be rigid to prevent it
from being squashed. Do not forget to check the connections for the screen (sealed with Teflon). Add clamps if necessary.
In any event, the suction hose should not be pointing upwards. When using in wells containing sand or gravel, place the screen
50cm from the bottom or in a bucket at the bottom of the well.
5) CONNECTING THE DISCHARGE HOSE
In order to avoid leakage and to obtain optimum output, it is essential to seal the connections with Teflon.
6) START-UP
Unscrew the filler cap from the body of the pump.
Using a suitable container, fill the body of the pump until it overflows. (Do not splash water onto electrical parts).
Replace the cap and tighten so that no air can enter.
If the water level drops in the body or it is not filling up properly, it is because there is an air intake. In this event, check
the suction hose connections, and then continue to refill the body.
Ensure that there is no water on the electrical parts of the pump.
Start up the pump and check again that there is no leakage from the body.
