Frequently Asked Questions - ARAL C 1500 ASTRALPOOL

How to prime the ARAL C 1500 pump?

To prime the pump, remove the prefilter cover by unscrewing the nut, then fill the pump with water through the prefilter until water comes out of the suction pipe. Make sure the basket is in place, then close the cover by tightening firmly.

What to do if the pump does not start?

First check the power supply and that the circuit breaker has not tripped. Check that the thermal protector is not activated. If the motor hums without turning, the motor may be blocked: disassemble the motor and contact technical support.

How to clean the prefilter basket?

Stop the pump and cut off power. Unscrew the prefilter cover, remove the basket and clean it under running water without knocking it to avoid breaking it. Replace the basket and close the cover, checking the condition of the seal.

What is the maximum water temperature tolerated by the pump?

The pump is designed to operate with water whose temperature does not exceed 35 °C. Above that, the mechanical seal and components may be damaged.

How to drain the pump for winter?

Cut off the power supply. Open the drain plug located under the pump to completely empty the water. If the pump is left unused in a cold area, this operation is essential to prevent freezing and damage.

What components need regular replacement?

The seals, mechanical seal, and bearings are wear parts. The manual indicates an estimated lifespan of 1 year under normal conditions. Replace them to maintain good performance.

What type of electrical cable to use for connection?

For a single-phase motor (230 V), use a H07 RN-F 3-wire cable with a cross-section suitable for the power and length. The cable must be connected by qualified personnel and the ground conductor properly connected.

The pump is noisy, what to check?

Abnormal noise can come from cavitation (air entry at suction), a clogged prefilter, incorrect mounting, or a blocked motor. Check the tightness of pipes, clean the basket, and ensure the pump is firmly fixed to the ground.

Can I use the pump if people are in the pool?

No, absolutely not. The manual states that the pump must not be used if people are in contact with water, due to the risk of electrocution. Wait until the pool is free of swimmers.

What to do in case of water leakage at the pump?

A leak may come from a worn seal or a poorly closed prefilter cover. Check the cover seal and clean impurities on its support. If the leak persists, replace the seal or contact technical support.

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 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 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.
• Make sure that the pump is safe from possible flooding and receives dry ventilation.

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 connection, 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 single-phase motor:

• Thermal protection is incorporated.
- 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 230 V, 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 230/400 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.

4. 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 (Fig. 5).
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. Check that the mains voltage and frequency correspond with those indicated on the pump characteristics plate.

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

6. 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).

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

- 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 (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.
