These pumps cannot be used in swimming pools, ponds or tanks in which people or present, or for pumping hydrocarbons (petrol, diesel fuel, fuel oils, solvents, etc.) in accordance with the accident-prevention regulations in force.

N.B.: The liquid inside the pump, to lubricate the seal device, is not toxic but it may alter the characteristics of the water (if it is pure water) if there is a leak in the seal device.

3. WARNINGS

— The pump is provided with a carrying handle which may also be used to lower it into wells or deep holes with a rope or cable.

- 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.

- T he pump must never be allowed to run dry.

4. INSTALLAZIONE

4.1 If the bottom of the well or borehole in which the pump is to operate is particularly dirty, it is advisable to provide a support for the pump to sit on so as to avoid clogging of the intake grid (Fig.1).
4.2 Before putting the pump in position, ensure that the strainer is not totally or partially blocked by mud, sediment or similar substances.
4.3 It is advisable to use pipes with an internal diameter at least equal to that of the delivery mouth, to avoid falls in pump performance and the possibility of clogging. In cases where the delivery pipe has long horizontal stretches, it is advisable for this pipe to have a larger diameter than that of the delivery mouth.

Totally immerse the pump in the water.

4.4

23.6" x 23.6" 600mmx600mm ON OFF Fig.

1. Connect the delivery pipe or hose directly to the pump mouth. If the pump is used in fixed installations it is advisable to connect it to the pipe with a coupling so as to facilitate disassembly and reinstallation. If a hose is used, fit a threaded hosetail on the pump mouth. Wrap the thread with suitable material to ensure an effective seal (teflon tape or similar).
2. On the version provided with a float switch, ensure that the float can move freely (SEE THE PARAGRAPH ON ADJUSTING THE FLOAT SWITCH). Ensure that the minimum dimensions of the borehole are as in Fig.1. 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.
3. 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.

5. ELECTRIC CONNECTION

Caution: always follow the safety regulations!

5.1 Single-phase motors are provided with built-in thermal overload protection and may be connected directly to the mains. N.B. If the motor is overloaded it stops automatically. Once it has cooled down it starts again automatically without any need for manual intervention.

5.2 Three-phase pumps must be protected with motor protectors suitably calibrated according to the values on the data plate of the pump to be installed.

5.3 Do not damage or cut the power cable. If this should occur accidentally, have it repaired or replaced by skilled and qualified personnel.

6. CHECKING THE DIRECTION OF ROTATION (for three-phase motors)

The direction of rotation must be checked each time a new installation is made.

Proceed as follows (Fig.2):

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 (anti-clockwise).

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.
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!

7. STARTING UP

Models with a float switch start up automatically when the water level rises; models without a float are started by means of a switch located upstream from the socket (not supplied).

Adjusting the float switch

Fig.3

Lengthening or shortening the cable between the float and the fixed point (slot provided in the handle - Fig.3) adjusts the START or STOP level of the pump. Be sure that the float can move freely.

Ensure that the stop level does not uncover the strainer.

8. PRECAUTIONS

8.1 The intake strainer must always be in place during pump operation.
8.2 The pump should not be started more than 20 times in one hour so as not to subject the motor to excessive thermal shock.
8.3 DANGER OF FROST: When the pump remains inactive for a long time at temperatures of less than 0^ C, it is necessary to ensure that there is no water residue which could freeze and cause cracking of the pump components.
8.4 If the pump has been used with substances which tend to form a deposit, rinse it after use with a powerful jet of water so as to avoid the formation of deposits or scale which would tend to reduce the yield of the pump.

8.5

Connect pumps that are delivered without cable and/or plugs to an external mains switch with a minimum contact gap of 0.12" / 3 mm in all poles.

9. MAINTENANCE AND CLEANING

In normal operation, the pump does not require any specific maintenance, thanks to its mechanical seal lubricated in an oil chamber and to its sealed-for-life bearings. 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.

During disassembly, pay attention to any sharp parts which could cause injury.

Checking and changing the sealing oil

To perform this operation you must unscrew the six screws of the flange (45) so as to be able to remove the flange (105) and the outer jacket (77). Unscrew the three screws of the filter cover (136) and remove the cover (92) and the filter (42). Unscrew the four screws of the pump body (52) and remove the pump body (1). Using a suitable wrench, unscrew the nut (18) that blocks the impeller, holding the impeller (4) still with your hand. Remove the impeller (4), if necessary with the aid of levers. Recover the tab (17) and the sand protection ring (15), unscrew and remove the cap (64). Tilt the pump so as to drain the oil out of the hole of the cap (64) and pour it into a container. Analyse the oil: if you find any particles of water or abrasive materials (for example, sand) it is advisable to check the condition of the mechanical seal (16) and to have it changed if necessary (at a specialized centre). In this case change the oil too, with about 6 oz / 170 gr of oil type MARCOL 152 ESSO.

Top up the oil level inside the sealing oil chamber using a special funnel inserted in the hole in the cap (64). Screw the drainage cap (64) back on and perform the disassembly operations in inverse order to reassemble the pump after having spread a suitable amount of teflon grease in the seat of the sand guard (15).

Attention! During assembly, fit all the O-rings correctly, without damaging them.

OLD OIL MUST BE DISPOSED OF AS REQUIRED BY THE REGULATIONS IN FORCE.
