Frequently Asked Questions - EuroInox 30/50 M DAB

What to do if the motor does not start and makes no noise?

Check the electrical connections, supply voltage and fuses. If a fuse is blown, replace it. If the problem persists, the motor may be short-circuited and require repair by a professional.

Why does the motor hum without starting?

This may be due to incorrect voltage, wrong connection, missing phase (three-phase), mechanical blockage or defective capacitor. Check each point: correct the voltage, read the diagram, restore the phase, unblock the pump or replace the capacitor.

How to prime the pump before first use?

Remove the filling cap on the pump body, pour clean water until the pump is completely filled, then carefully screw the cap back on. Never run the pump dry, as this would irreparably damage the mechanical seal.

What to do if the pump does not discharge water?

Ensure the pump is properly primed. For three-phase motors, check the rotation direction (must be clockwise when viewed from the fan). Also check the suction pipe diameter and clean the foot valve if blocked.

How to check the rotation direction on a three-phase motor?

After priming and powering the pump, look at the fan on the motor side: it must rotate clockwise. If not, cut the power and swap two phase conductors in the terminal box.

The pump vibrates abnormally, what to do?

Check that the pump and piping are firmly fixed. If vibrations persist, there may be cavitation (excessive water demand) or operation outside limits. Reduce the suction height or limit the discharge flow.

What electrical protection is required for outdoor installation?

For outdoor use (fountain, pond), the pump must be powered via a circuit with a residual current device not exceeding 30 mA. Comply with local safety standards.

Flow is insufficient, what are the possible causes?

Common causes: blocked foot valve, clogged or worn impeller, suction pipe too narrow, or wrong rotation direction (three-phase). Clean or replace defective parts and check rotation.

How to replace the power cable?

Cut the power. Unscrew the terminal box cover, loosen terminals L, N, earth and the cable gland, then remove the old cable. Install a cable of the same type (H05 RN-F or H07 RN-F), reversing the disassembly order. Have this operation performed by a professional if necessary.

How many starts per hour can the pump withstand?

Do not exceed 20 starts per hour to avoid excessive thermal stress on the motor. After a long period of inactivity, re-prime before restarting.

3. MANAGEMENT

3.1 Storage

All the pumps must be stored indoors, in a dry, vibration-free and dust-free environment, possibly with constant air humidity.

They are supplied in their original packaging and must remain there until the time of installation. If this is not possible, the intake and delivery aperture must be accurately closed.

3.2 Transport

Avoid subjecting the products to needless jolts or collisions.

To lift and transport the unit, use lifting equipment and the pallet supplied standard (if applicable).

3.3 Weights

The adhesive label on the package indicates the total weight of the electropump.

3.4 Checking motor shaft rotation

Before installing the pump you must check that the rotating parts turn freely. For this purpose remove the fan cover from its seat in the motor end cover. Insert a screwdriver in the notch on the motor shaft from the ventilation side. If there is a blockage, turn the screwdriver, tapping it gently with a hammer. FIG. A

4. INSTALLATION

The pumps may contain small quantities of residual water from testing. We advise flushing them briefly with clean water before their final installation.

4.1 The electropump must be fitted in a well ventilated place, protected from unfavourable weather conditions and with an environment temperature not exceeding 40^ C. Fig.B

4.2 A firm anchoring of the pump to the bearing surface favours the absorption of any vibrations caused by pump operation. Fig. C

4.3 Ensure that the metal pipes do not exert undue strain on the apertures, thus preventing deformations or breakages. Fig. C

4.4 The lifting and carrying handle must always be present and well fixed to the support on all pumps produced in the portable version.

4.5 Pumps that are to be used in fountains for outdoor use, in garden ponds and similar places, must be fed by means of a circuit equipped with a differential current device, the rated operating differential current of which is not higher than 30 mA.

5. ELECTRICAL CONNECTION

Caution! always follow the safety regulations.

Scrupulously follow the wiring diagrams inside the terminal board box.

5.1 In fixed installations, International Safety Standards require the use of isolating switches with a fuse-carrier base.

5.2 Single-phase motors are provided with built-in thermal overload protection and may be connected directly to the mains. Three-phase motors must be protected with an automatic switch (e.g. overload protection) set at the values on the electropump data plate.

5.3 In the power mains there must be a device that ensures complete disconnection in overvoltage category III conditions.

6. STARTING UP

Do not start the pump unless it has been completely filled with fluid.

Before starting up, check that the pump is properly primed; fill it completely with clean water by means of the hole provided after having removed the filler cap on the pump body (Fig. F). Dry operation causes irreparable damage to the mechanical seal. The filling cap must then be screwed back on carefully.

6.2 Switch on the power and check, on the three-phase version, that the motor is turning in the correct direction; this should be in a clockwise direction, looking at the motor from the impeller side. Fig. G If it is turning in the wrong direction, invert the connections of any two wires on the terminal board, after having disconnected the pump from the power mains.

7. PRECAUTIONS

7.1 The electropump should not be started more than 20 times in one hour so as not to subject the motor to excessive thermal shock.

7.2 When starting after long periods of inactivity, the starting-up operations listed above must be repeated.

7.3 It is always good practice to place the pump as close as possible to the liquid to be pumped (Fig.1 - Pag.74)

8. MAINTENANCE AND CLEANING

The electropump must not be dismantled unless by skilled personnel in possession of the qualifications required by the regulations in force. In any case, all repairs and maintenance jobs must be carried out only after having disconnected the pump from the power mains.

9. MODIFICATIONS AND SPARE PARTS

Any modification not authorized beforehand relieves the manufacturer of all responsibility.

In the event of damage to the power cable of this appliance, the repair must be carried out by skilled personnel, in order to prevent all risks.

9.1 Removal and replacement of the supply cable

Before starting, ensure that the electropump is not connected to the power network.

For versions without a pressure switch: Remove the condenser cover, unscrewing the four screws on it. Unscrew the three terminals L - N - ① and disconnect the brown lead, the blue lead and the yellow-green lead, coming from the supply cable, after having slackened the grommet.

Version with a TELEMECANIQUE / SQUARE D - TELEMECANIQUE / ITALTECNICA pressure switch:

- Section of cable with plug from the pressure switch: unscrew the screw from the cover of the pressure switch using a screwdriver and remove the cover, releasing it from the base of the pressure switch. Slip out the yellow-green lead, unscrewing the earth screw on the left side. Still on the same side, slip the blue lead and the brown lead off their terminals, slackening the screws on the terminals. Slacken the cable clamping nut of the pressure switch on the left side and slip off the cable which is now disconnected.

- Section of cable from the pressure switch to the terminal board: unscrew the nut on the cover of the pressure switch using a screwdriver and remove the cover, releasing it from the base of the pressure switch. Slip out the yellow-green lead, unscrewing the earth screw on the right side. Still on the same side, slip the blue lead and the brown lead off their terminals, slackening the screws on the terminals. Slacken the cable clamping nut of the pressure switch on the right side and slip off the cable which is now disconnected. Remove the terminal board

cover, unscrewing the four screws on it. Unscrew the three terminals L - N - ⊕ and disconnect the brown lead, the blue lead and the yellow-green lead, coming from the supply pressure switch, after having slackened the grommet.

When replacing the power cable, a cable of the same type must be used (e.g. H05 RN-F or H07 RN-F depending on the installation) and with the same terminals, proceeding as for disassembly in inverse order.

ATTENTION: depending on the installation and if the pumps have no cable, fit supply cables type H05 RN-F for indoor use and type H07 RN-F for outdoor use, complete with plug (EN 60335-2-41). For power cables without a plug, provide a device for cutting off the mains (e.g. magnetothermal device) with separating contacts of at least 3 mm for each pole.
