5. MANAGEMENT

5.1 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 discharge ports must be accurately closed.

5.2 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).

5.3 Weights

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

6. WARNINGS

6.1 Skilled technical personnel

It is advisable that installation be carried out by skilled personnel in possession of the technical qualifications required by the specific legislation in force.

The term skilled personnel means persons whose training, experience and instruction, as well as their knowledge of the respective standards and requirements for accident prevention and working conditions, have been approved by the person in charge of plant safety, authorizing them to perform all the necessary activities, during which they are able to recognize and avoid all dangers.

6.2 Safety

Use is allowed only if the electric system is in possession of safety precautions in accordance with the regulations in force in the country where the product is installed.

6.3 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

6.4 Responsibility

The Manufacturer does not vouch for correct operation of the pumps if they are tampered with or modified, run outside the recommended work range or in contrast with the other instructions given in this manual. The Manufacturer declines all responsibility for possible errors in this instructions manual, if due to misprints or errors in copying. The company reserves the right to make any modifications to products that it may consider necessary or useful, without affecting the essential characteristics.

7. INSTALLATION

7.1 The pump must be fitted in a well ventilated place, protected from unfavorable weather conditions and with an environment temperature not exceeding 104^ (40^) . Fig.B

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

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

7.4 It is always good practice to place the pump as close as possible to the liquid to be pumped. The pump must be installed only in horizontal position. The internal diameters of the pipes must never be smaller than that of the mouth of the pump. It is advisable to fit a foot valve on suction. Fig. D For suction depths of over 13ft (4 m), or with long horizontal stretches it is advisable to use an intake hose with a diameter larger than that of the intake aperture of the pump. To prevent the formation of air pockets, the intake hose must slope slightly upwards towards the pump. Fig. D

7.5 If the intake pipe is made of rubber or flexible material, always check that it is of the reinforced type to avoid throttling due to suction.

8. ELECTRICAL CONNECTION

Caution! always follow the safety regulations.

Please follow the wiring diagrams inside the pressure box.

8.1 All electrical work should be performed by a qualified electrician in accordance with the latest edition of the National Electrical Code, local codes and regulations.

Ensure that the mains voltage is the same as the value shown on the motor plate. A faulty motor or winding can cause electrical shock that could be fatal, whether touched directly or conducted through standing water. For this reason, proper grounding of the pump to the power supply's grounding terminal is required for safe installations, the above-ground metal plumbing should be connected to the power supply as a ground as described in Article 250-80 of the National Electrical Code or Section 26-954 of the Canadian.

8.2 In fixed installations, International Safety Standards require the use of isolating switches with a fuse-carrier base.
8.3 Single-phase motors are provided with built-in thermal overload protection with automatic reset, and may be connected directly to the mains.

FITTING THE VOLTAGE CONVERTER

• Check the voltage indicated on the side of the voltage converter.
• Turn the indicator so that the desired voltage points towards the side with the "M" lock catch.
• The arrow on the converter next to the required voltage must be aligned with the "F" arrow on the housing.
  Push the converter into position until the reference catch "M" clips in place.

9. STARTING UP

9.1

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. This ensures that the mechanical seal is well lubricated and that the pump immediately starts to work regularly. (Fig. F). Dry operation causes irreparable damage to the mechanical seal. The filling cap must then be screwed back on carefully.

10. PRECAUTIONS

10.1 The pump should not be started more than 20 times in one hour so as not to subject the motor to excessive thermal shock.
10.2 DANGER OF FROST: When the pump remains inactive for a long time at temperatures of less than 32^ (0^) , the pump body must be completely emptied through the drain cap Fig. H, to prevent possible cracking of the hydraulic components. This operation is advisable even in the event of prolonged inactivity at normal temperature.
10.3 When starting after long periods of inactivity, the starting-up operations listed above must be repeated.

11. MAINTENANCE AND CLEANING

In normal operation, the pump does not require any specific maintenance. However, it may be necessary to clean the hydraulic parts when a decrease in performance is observed. The pump 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.

12. MODIFICATIONS AND SPARE PARTS

Any modification not authorized beforehand relieves the manufacturer of all responsibility. All the spare parts used in repairs must be original ones and the accessories must be approved by the manufacturer so as to be able to guarantee maximum safety of the machines and systems in which they may be fitted.

12.1 Removal and replacement of the supply cable

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

Unscrew the screw from the cover of the pressure switch using a screwdriver and remove the cover. Remove the yellow-green lead, slackening the earth screw, the blue lead and the brown lead from the respective terminals at the side, slackening the screws on the terminals. Remove the cable blocking terminal, slackening the respective screws, and slip off the cable which is now disconnected.

When replacing the power cable, a cable of the same type must be used and with the same terminals, proceeding as for disassembly in inverse order.

ATTENTION:

For power cables with a plug, fit a device for disconnecting the power network (e.g. a magnetothermal switch) with separation contacts of at least 0.12^ . for each pole.

13. INSTRUCTIONS FOR ADJUSTING THE PRESSURE SWITCH
