g) When operating outdoors, the electrical connections must be splash-proof; they must not lie in water.
h) Extension cords must have sufficient wire cross section; cable drums must be complete unwound.

4.3.2- For three-phase model 400V (see Fig.2)
Product is supplied with H07 RN-F cable and with no plug.
Please seek help from a qualified electrician to perform the electrical connection.
Then proceed with same as above, except for point c).
4.4- Connection of the suction pipe (not included)
The suction pipe (not included) must have a minimum diameter of 25mm or 32 mm according to model [refer
to specs table] and be rigid enough to prevent crushing.
The assembly of the pipe must be carried out using Teflon to ensure complete air-tightness.
In the case of fittings with gaskets or O-rings, it is not necessary to use Teflon.
Ensure that the gaskets hold firm over time.
We recommend fitting a strainer (mounting with Teflon). Use clamping rings if necessary.
In all cases, the suction pipe must not be oriented upwards.
In the case of a pumping chamber with sand or gravel, position the strainer 50cm from the bottom or in a
bucket at the bottom of the chamber.
The suction line should be as short as possible, since the suction capacity decreases as the length of the line
increases.
The suction line should ascend steadily towards the pump to prevent air pockets.
Sufficient water supply must be assured; the end of the suction line must always be in water.
The suction line must be installed so that it does not exert any mechanical force or tension on the pump.
If the conveying medium is contaminated, a suction filter must be used to protect the pump from sand and dirt.
IMPORTANT! It is highly recommended to install a non-return valve in the suction line.
4.5- Connection of the discharge pipe (not included)
The discharge pipe (not included) must have a minimum diameter of 25mm and be rigid to prevent crushing.
In order to avoid leaks and obtain optimum performance, it is important to mount the fittings using Teflon.
Remarks:
- All components of the pressure line must be compression-proof.
- All components of the pressure line must be professionally installed
- If the components are not compression-proof or if they are improperly installed, the pressure line could burst
during operation. Risk of injury from liquid spurting out!
4.6- Start-up
Warning! The pump should be filled with water after each new connection or in the event of water loss or air
intake. Extended operation without a water refill (unsupervised dry run) will destroy the pump.
- Unscrew the priming screw on the pump casing.
- Using a receptacle, fill the pump body until overflowing occurs.
Do not splash water on the electrical parts.
- Put the priming screw back and screw it sufficiently tight to prevent air intake.
- If the water level drops in the pump body or the water does not discharge properly, it is likely due to air
intake; therefore, switch off the pump and re-examine the suction pipe fittings and proceed again with priming
by filling water in the pump body.
Ensure that there is no water on the electrical parts of the pump.
- Start the pump and check there is no leakage on the pump body, suction line and fittings.
When water runs out evenly, turn the pump off. The pump is ready for use.
- If the water does not flow and the pump does not suck water, make sure there are no leaks in the pump body,
pipes and fittings
