5. LOCATION
Warning: Do not install the pump in enclosed or poorly ventilated environments where conditions may be unfavourable for
the presence of staff. Ensure that there is enough light on the pump for the installer.
- Fit the pump underneath the water level in the pool to improve pump performance.
- Where a self-priming pump is to be fitted above the water level, the pressure differential to the pump suction should
not be higher than 0.02 MPa (2 mH2O), ensuring that the suction pipe is as short as possible as a longer pipe would
increase suction time and the installation’s load losses.
- Self-priming Kivu pumps are 3cv ,4cv and 5.5cv models with prefilter.
- Make sure that the pump is safe from possible flooding and receives dry ventilation.
6. INSTALLATION AND ASSEMBLY
- Our pumps may only be assembled and installed in pools or ponds that are compliant with HD 384.7.702. Should
you have any doubts, please consult your specialist.
- Fit the pump horizontally due to the pre-filter. The pumps are fitted with a pre-filter with a basket inside to collect any
large particles, as they may damage the hydraulic part inside the pump.
- All pumps are fitted with a foot with holes in it to anchor it to the ground.
INSTALLATION
- The pumps should be installed horizontally.
- The pumps need a free space of 0.5 m behind the motor and at
least 1 m above the motor so that lifting equipment can be used.

INSTALLING PIPES (RECOMMENDATIONS)
When installing the pipes, ensure that the pump body is not under pressure from the pipes.
The suction and discharge pipes should be of the correct size, taking into account the inlet pressure of the pump.
Install the pipes so that air pockets are avoided, especially on the suction end of the pump.
Assemble the shut-off valves on both sides of the pump to prevent the system from emptying if we have to clean or repair
the pump.
Check that the pipes are held in place as close as possible to the pump, both on the suction and the discharge sides. The
counter flanges should be aligned with respect to the pump flanges, without stresses that could cause damage to it.
The pump cannot operate when a valve is closed, as this will cause an increase in the temperature/formation of steam in
the pump, which may cause it damage.

ELIMINATING NOISE AND VIBRATIONS
For optimum operation and to reduce noise and vibrations to a minimum, we advise the use of vibration absorbers.
Noise and vibrations are generated by the revolutions of the pump motor and by the flow in pipes and connectors. Their
effect on the environment is subjective and depends on the correct installation and condition of the other parts of the system.
The best way of eliminating noise and vibrations is to use a concrete foundation, vibration absorbers and expansion joints.
7. ELECTRICAL INSTALLATION
- It is essential that you use a multiple disconnection device with a space of at least 3 mm between surfaces to disconnect
the equipment from the electrical current.
- Use a rigid cable to connect to the mains. If you use a flexible cable to connect to the mains, it must have cable lugs to
connect to the terminals of the pump motor.
- The equipment should be connected to an alternating current supply (see data on the pump’s plate) with earth connec-
tion, protected by a residual current device (RCD) having a rated residual operating current not exceeding 30 mA.
- Adjust the value of the thermal relay appropriately depending on the pump current.
- Before connecting the motor, check the type of fuse required.
- Check the correct layout and connection of the earthing cable in the equipment.
- Respect the electrical installation and connection conditions. Failure to do so may lead to the pump manufacturer
declining all responsibility and rendering the guarantee null and void.
- Special regulations may exist for the installation.
- Unsuitable mains connections involve the risk of electrocution.
For pumps with a three-phase motor:
• Use a motor guard with magneto-thermal protection.
• Protect the pump against overloads with a cut-off switch for the motor.

• Adjust the thermal value according to the thermal protection table. For the connection ∆(3 x 230 V network), use the protection
with the highest indicated value. For the connection Υ(3 x 400 V network), use the protection with the lowest indicated value.
• Connect the lowest voltage at ∆and the highest at Υfor voltage intervals other than 230/400 V; 400/690 V.
• For AC, use a H07 RN-F3 type connection sleeve with a cable section that adapts to the power of the motor and the
length of the cable.
• The mains cable may only be connected by skilled, authorised personnel.
VARIABLE FREQUENCY DRIVE
• These pumps are suitable for use with a variable frequency drive.
• It is recommended that you work within the limits of 20Hz to 50Hz.
• For more information, contact the supplier of the variable frequency drive.
8. START-UP INSTRUCTIONS
PRIOR TO START-UP
- Carry out the following operations before starting the pump:
1. Remove the pre-filter cap by unscrewing the nut holding it in place.
2. Fill the pump with water through the pre-filter until it rises up through the suction pipe.
3. Should the basket be removed during these operations, do not forget to replace it to prevent large particles from
entering the pump that could block it.
4. Fit the pre-filter cap and screw on tight, not forgetting to fit the seal in its housing.
5. Check that the mains voltage and frequency correspond with those indicated on the pump characteristics plate.
- The pumps must not be run without the pre-filter having first been filled with water. Where this is not the case, the
mechanical gasket may be damaged, leading to a loss of water.
- Check that the motor rotates in the correct direction by means of the fan located at the back of the motor that can be seen
through the view hole on the fan cover.
START-UP
- Open all the valves and connect the motor.
- Activate the self-priming and wait a reasonable time for this to be completed.
- The PUMP MUST NEVER FUNCTION WHEN IT IS DRY. The pump must not be started when it is dry as this would cause
damage to its mechanical seal, causing water leaks.
- The pump cannot function against a closed valve as this will cause an increase in the temperature and formation of
steam in the pump, which could cause it damage.
MINIMUM PRESSURE -NPSHr /CAVITATION
- The minimum suction pressure depends on the flow rate and power of the Kivu pump. See NPSHr graphs.
- If the pump does not have the minimum pressure required, it can cavitate. Steam would cause vibrations that would
damage the moving parts of the pump (impeller, mechanical seal, bearings) and fixed parts (flange, diffuser, volute).
- To avoid the effect of cavitation in the pump, ensure that the minimum pressure at the inlet of the pump is that required
in the NPSHr graph.

ENGLISH
10 KIVU PUMP - ASTRALPOOL
MAXIMUM FLOW RATE
- The maximum flow rate is determined by the minimum differential pressure of the pump. The minimum pressure should
never be less than that indicated on the pump label. (Fig.4)
MINIMUM FLOW RATE
- The pump should not work against a closed discharge valve, as this would cause an increase in temperature which could
damage parts of the pump and shorten its useful life.
- The continuous minimum flow rate must be at least 10% of the nominal flow rate indicated on the pump label. (Fig.4).
9. MAINTENANCE
- For regular control:
• Check that the mechanical parts are tightly secured and check the condition of the screws supporting the machine.
• Clean the pre-filter basket regularly to avoid drops in pressure. To prevent the basket from breaking, do not hit it
during the cleaning process.
• The pump should be checked every 100 hours of operation or less, depending on the level of cleanliness of the water.
• Check the temperature of the machine and the electric motor. In the event of a fault, stop the machine immediately and
contact the nearest Technical Assistance Service.
• Check for machine vibrations. In the event of a fault, stop the machine immediately and contact the nearest Technical
Assistance Service.
- Should the pump stop, check that consumption of the running motor in amperes is equal to or below that indicated on
the manufacturer’s characteristics plate. If this information is available, contact the nearest Technical Assistance Service.
- Empty the pump if it is to remain at a standstill for a certain length of time, especially in cold countries where there is a
risk of freezing.
- Remove the purge cap to empty the pump.
- Every time the pre-filter is opened, clean the seal and its seating of any impurities to ensure airtightness when the cap
is closed.
- Pump components that, due to their normal use, suffer wear and/or tear must be regularly replaced to ensure good pump
performance. The following table shows the perishables and/or consumables used in the pump and their estimated
working life.
COMPONENT DESCRIPTION ESTIMATED WORKING LIFE
O rings and general seals 1 year
Mechanical seal 1 year
Bearings 1 year
The estimated working life of the parts above has been established according to normal product use and installation conditions.
Follow the instructions in the installation manual to maintain the working life of the pump.
10. REMOVAL
- The motor unit can be removed from the pump body without having to disconnect the pump’s suction and return pipes.
