MANAGEMENT

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.

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).

Weights

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

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
Management

INSTALLATION

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

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
A firm anchoring of the pump to the bearing surface favours the absorption of any vibrations caused by pump operation. Fig. C
Ensure that the metal pipes do not exert undue strain on the apertures, thus preventing deformations or breakages. Fig. C
The lifting and carrying handle must always be present and well fixed to the support on all pumps produced in the portable version.
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.

ELECTRICAL CONNECTION

Caution! always follow the safety regulations.
Scrupulously follow the wiring diagrams inside the terminal board box.

In fixed installations, International Safety Standards require the use of isolating switches with a fuse-carrier base.
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.
In the power mains there must be a device that ensures complete disconnection in overvoltage category III conditions.

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.
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.

PRECAUTIONS

The electropump should not be started more than 20 times in one hour so as not to subject the motor to excessive thermal shock.
When starting after long periods of inactivity, the starting-up operations listed above must be repeated.
It is always good practice to place the pump as close as possible to the liquid to be pumped (Fig.I – Pag.74)

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.

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.

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 – and disconnect the brown lead, the blue lead and the yellow-green lead, coming from the supply cable, after having slackened the grommet.

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.

TROUBLESHOOTING

D. Blocked foot valve.

|

B. If necessary, invert the connection of two supply wires
C. Replace the pipe with one with a larger diameter.
D. Clean the foot valve.

The pump does not prime.|

A. The intake pipe or the foot valve is taking in air.
