Frequently Asked Questions - POOL PUMPS ASTRALPOOL

The pump does not prime, what to do?

Check the tightness of the suction hose and the pre-filter cover. Fill the pre-filter with water until it comes out of the suction pipe. Make sure the motor rotation direction is correct.

How to clean the pre-filter basket?

Remove the pre-filter cover, take out the basket and clean it without knocking to avoid breaking it. Put it back and close the cover with its seal.

The pump makes noise, possible causes?

Possible causes: air intake through the suction hose, poor seal of the filter cover, reversed motor rotation, clogged pre-filter, or incorrect pump mounting.

Can I program the pump to adjust the flow according to the hours?

Standard ASTRALPOOL pumps do not have built-in time programming. You can manually adjust the flow via valves or, on variable speed models, adjust the speed. For automation, use an external timer or contact customer service.

How to drain the pump before winter?

Remove the drain plug located on the pump body to empty the water. If the pump remains unused for a long time, especially in cold areas, this operation prevents frost damage.

What type of electrical cable to use?

Use a rigid or flexible cable of type H07 RN-F with 3 conductors, with a section adapted to the motor power and cable length. For three-phase, follow the connection diagram (Δ or Y) according to voltage.

What is the recommended periodic maintenance?

Clean the pre-filter basket regularly. Check the condition of seals and mechanical seal annually. Monitor electrical consumption and motor temperature. In case of anomaly, stop the pump and contact technical service.

The pump does not start, what to check?

Check the power supply, mains voltage, thermal protector, connections in the junction box, and that the motor turns freely. If the problem persists, consult technical service.

Can I install the pump above water level?

Yes, but the height must not exceed 2 meters above water level. The suction hose should be as short as possible and inclined at 2% towards the pump to avoid air pockets.

How to reverse the motor rotation direction?

To reverse the direction, swap two power phases in the case of a three-phase motor. For single-phase, the direction is usually fixed; refer to the motor manual.

3. INSTALLATION AND ASSEMBLY

GENERAL

• 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 two holes in it to anchor it to the ground (Fig. 1).

PIPING

• To connect the piping, glue the pipes and the connectors, supplied together with the pump; the fitting connections to the suction and return ports on the pump are threaded and include seals to prevent water loss (Fig. 2).
• Fit the return pipes completely perpendicular and centred in relation to the port to be connected to prevent the pump and the pipe from being subjected to external stress that, apart from making fitting difficult, could break them (Fig. 2).
• Fit the suction piping on a slight 2% slope towards the pump to avoid the formation of air pockets (Fig. 2).
• To ensure the pump works correctly, prime the pump pre-filter until water rises up through the suction pipe (Fig. 3).

LOCATION

• 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 difference in height must be no more than 2 metres (Fig. 4), ensuring that the suction pipe is as short as possible as a long pipe would increase drainage times and load losses in the installation.
• Make sure that the pump is safe from possible flooding and receives dry ventilation.

ELECTRICAL INSTALLATION

• The electrical installation must include a multiple separation system with contact openings of at least 3mm
• 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.
• With any type of pump, 0.03 A differential protection must be fitted for electricity leakage protection (indicated on the diagrams).
• Adjust the value of the thermal relay appropriately depending on the pump current.

For pumps with a single-phase motor:

• Thermal protection is incorporated. Installation with a switch is sufficient, in line with the "Mains connections" diagram.
• Use a motor guard with magneto-thermal protection.
• The adjustment data for the thermal relay is to be used as a guideline, as the motor is already fitted with protection.
• For 230V , use a H07 RN-F3 type connection sleeve with a cable section that adapts to the power of the motor and to the length of the cable.

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 Y (3 x 400 V network), use the protection with the lowest indicated value.

Connect the lowest voltage at and the highest at Y for voltage intervals other than 230 / 400V;400 / 690V.
- 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.

• 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.
• The motors are subject to the EEC standards with IP-55 protection.
• Special regulations may exist for the installation.
• Unsuitable mains connections involve the risk of death.

4. START-UP INSTRUCTIONS

PRIOR TO START-UP

• Carry out the following operations before starting the pump:

• Remove the pre-filter cap by unscrewing the nut holding it in place (Fig. 5).

• Fill the pump with water through the pre-filter until it rises up through the suction pipe.
• 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.

• Check that the mains voltage and power correspond with those indicated on the pump characteristics plate.

• Fit the pre-filter cap and screw on tight, not forgetting to fit the seal in its housing (Fig. 5).

• 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 (Fig. 6).
• Check that the pump shaft turns freely.

START-UP

• Open all the valves and connect the motor.
• Activate the self-priming and wait a reasonable time for this to be completed.

5. MAINTENANCE

• 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.
• 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.

• Where the amperage is higher, consult the manufacturer.

• 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 (10) 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 (Fig. 5).
• 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.
