The direction of rotation must be checked each time a new installation is made.
Proceed as follows:
1) Place the pump on a flat surface.
2) Start the pump and stop it immediately.
3) Carefully observe the kick-back on starting, looking at the pump from the motor side. The direction of rotation is correct, that is clockwise, if the protection cap moves as in the drawing (anticlockwise).
4) If the motor is turning in the wrong direction, switch off the power and invert two phases on the supply line (upstream from the control unit).
If it is not possible to check as described above because the pump is already installed, check as follows:
1) Start the pump and observe the water flow rate.
2) Stop the pump, switch off the power and invert two phases on the supply line (upstream from the control unit).
3) Restart the pump and check the water flow rate again.
4) Stop the pump.
The correct direction of rotation is the one that gives the higher flow rate.
It is not necessary to check the direction of rotation of single-phase motors. We recommend you read the instruction manual of the Drenag 1400, Drenag 1800 (also available in our DNA software) for useful information for use, maintenance and installation.

Yes, it can only be done but only by experienced staff. In addition, all electrical connections must be protected from moisture and any joints must be completely watertight when immersed. The length and thickness of the electrical wires should follow the following table:

Before starting the electric pump check again electric and hydraulic connections and relevant rating. Check that all safety procedures and their good functioning have been activated. Check that the electric pump is correctly immerged and that the liquid level is allowing correct starting. Start the electric pump and check that the current does not exceed the plate value and that the supply voltage is within the foreseen limits. Adjust, when present, the correct rating of the protection relay according to the working current value, the relay must be rated 10% more than the electric pump plate value. If the unit does not start, do not insist. Identify the malfunction and repair the causes. We recommend you read the instruction manual of the Drenag 1600, Drenag 2000, Drenag 2500, Drenag 3000 (also available in our DNA software) for useful information for use, maintenance and installation.

The single phase electric pump rotates always in the correct direction.
In case of wrong rotation direction stop immediately the electric pump and inform the distributor or the Technical office.
Check’ the exact rotation direction of three-phase electric pumps proceeding as follows:
-    Slightly tilt the pump to one side or hang it from a lifting means;
-    Start the electric pump for a few seconds, making sure that the kick-back does not become a danger hazard;
-    The correct direction is indicated by harrows on the electric pump cover and pump body. If the kick-back has been anti-clock wise viewing the electric pump from above, then the rotation direction is correct
If the rotation direction is wrong, disconnect the power supply and reconnect the electric pump to the main by switching two of the three phases with each other. The rotation direction must be checked again every time the electric pump is electrically disconnected or an intervention is necessary in case of phase failure. attention! The running on wrong rotation direction causes an overload to the motor and heavy damages to the electric pump.We recommend you read the instruction manual of the Drenag 1600, Drenag 2000, Drenag 2500, Drenag 3000 (also available in our DNA software) for useful information for use, maintenance and installation.

In case it should be necessary to extend the length of the electric cable verify the good quality and the correct section in relation with the length and the motor power.
The connection must be executed by care of skilled personnel and with materials that guarantee a perfect insulation of conductors, tightness and impermeableness lasting in time.
The eventual replacement of electric cable must be carried out by skilled personnel using electric cable H07RN-F. The cable is suitable for connection type M according to normatives EN-i-60335-1 (CEI 61-50). We recommend you read the instruction manual of the Drenag 1600, Drenag 2000, Drenag 2500, Drenag 3000 (also available in our DNA software) for useful information for use, maintenance and installation.

Before starting the pump, make sure that it is completely immersed in water. On the version provided with a float switch, ensure that the float can move freely. Ensure that the minimum dimensions of the borehole are as in the figure below. The dimensions of the borehole must also be calculated with relation to the quantity of water arriving and to the pump flow rate so as not to subject the motor to excessive starting operations. When the pump is to be in a fixed installation, with a float, a check valve must always be fitted in the delivery pipe. This is also advisable on pumps with manual operation.

3.    Restart the pump and check the water flow rate again.
4.    Stop the pump.
The correct direction of rotation will be the one in which the flow rate and electric absorption are LOWER!

Yes you can. If the power cable is damaged in any way it must be replaced and not repaired (use cable type H07RN-F) diam. 9 – 9.5 mm. with minimum length 10 metres for the portable version, with a UNEL 47166-68 plug for the SINGLE-PHASE version and with an EEC plug for the THREE-PHASE version).
This must be done by skilled personnel, in possession of the qualifications required by the regulations in force. We recommend you read the instruction manual of the Drenag 1000, Drenag 1200 (also available in our DNA software) for useful information for use, maintenance and installation.
