Electric Connections - Rover BE-M 10 Instrucciones Para El Uso

Make sure the power supply cable is in good condition before using the pump. Replace the cable before starting up the pump if you notice any abrasion, cuts (you can see the copper wire) or other general damage.
WARNING: the power supply cable can only be replaced using special tools. Said tools are normally only available from the manufacturer, ROVER POMPE retailers and professional repairers.

ELECTRIC CONNECTIONS

Pumps are delivered ready for use.
PUMPS WITH SINGLE-PHASE MOTORS
The motors in single-phase pumps are protected against overloading by means of an amperometric device (overload cutout) which is fitted to the start-up equipment.
When necessary, the overload cutout will trigger automatically by disconnecting the phase voltage from the motor for as long as it takes the motor to cool down. The overload cutout will then reactivate, and reset normal pump
operation.
WARNING: If you realise that the overload cutout triggers repeatedly, switch the pump off and remove the plug from the electric socket as this means the pump was operating in overload. If this overload was caused by the
faulty operation of the pump, call in a professional technician to check said pump.
PUMPS WITH THREE-PHASE MOTORS
Three-phase motors must be protected by the end user by means of a special electrical supply and protection panel.
WARNING: Work on the electrical panel and the installation of the pump must be carried out by a specialised technician in conformity with the general electrical safety standards currently in force. The dimensioning of the
devices for the electrical panel must be proportional to the electrical data specified on the pump plate.
N.B.: Installation of the pump may, at times, prove to be complex work. Before starting this work, users must consider both the local standards in force and use his or her common sense.
START-UP AND SELF-PRIMING
Position the pump horizontally, resting it on a steady non-slip base, away from heat sources and inflammable materials. The pump must be stable and rest entirely on its own feet.
Do not plug the plug into the socket.
If the pump body is empty, fill it with liquid before you start the pump in order to make priming easier.
The pump must be filled using one of the two pump hose adapters.
Connect the tubes up to the hose adapters, and fasten them using good quality hose clamps.
Use suitably sized pliers to tighten the ring nuts of the hose adapters. Do not damage the surface serration.
Set the start-up switch to the "0" rest position. Plug the plug into the socket, and turn the start-up switch in the direction required, clockwise or anticlockwise.
Once started, the pump will automatically draft the liquid. If suction does not occur within thirty seconds, switch the pump off, and remove the plug from the socket. Check both that the clamps and the hose adapter ring nuts are
tight enough, and the general conditions of the tube. Check the suction tube is connected to the suction hose adapter correctly (see start-up equipment and Fig. 6).
WARNING: make sure the quality of the hose clamps is such that they will guarantee long-lasting seal. Poor quality clamps may cause leakage, or the tube may even slip off the hose adapter. This will cause obviously damage
to the pump, the surrounding environment and the safety of any persons in the vicinity.
WARNING: If any liquid is accidentally spill on the pump during the manual filling phase, wipe it off immediately (using a dry cloth) before plugging the plug into the socket.
N.B.: WHEN CHOOSING THE TUBES TAKE INTO ACCOUNT THE KIND OF LIQUID WHICH IS TO BE TRANSFERRED. General tubes can be used for liquids which are not foodstuffs; non-toxic tubes which are specifically
marked as being suitable for foodstuffs must be used for liquid foodstuffs.
The tube chosen for aspiration must be equipped with a metal reinforcement spiral. This is because during operation the pump will create a depression and a badly chosen tube may thus be crushed.
The anti-tapping or foot valve must be connected up to the free end of the suction tube either when the difference of level between the pump axis and the level of the liquid exceeds 3 metres in height (pump above the level of the
liquid), or if the liquid has to be conveyed horizontally for long stretches. The suction tube must not let in air.
N.B.: The pump must be set as near to the level of the pumped liquid as possible during use. Do not use the pump when there is no liquid in the pump body.
The external temperature of the motor may reach 45° during normal operation. Although indeed this temperature is not dangerous, users may feel a burning sensation when they touch the device.
WARNING: The pump must be horizontal at all times. Do not move the pump while in operation.
Switch the pump off once pumping has been completed. This will block the flow of liquid, but the pump body will not empty. If you need to start pumping again, simply switch the pump on again, without refilling the body.
During priming, make sure that the by-pass valve in pumps with a by-pass (hydraulic regulator) is completely closed in order to ensure priming occurs.
WARNING: the suction and delivery tubes may move when the pump starts pumping, due to the dynamic flow of the liquid inside them. Make sure this does not occur.
