Frequently Asked Questions - SENA ASTRALPOOL

How to install the AstralPool SENA pump?

Install the pump horizontally, preferably below the water level. Secure it to the ground with anchors. Connect the piping using the supplied fittings, ensuring the pipes are well-centered to avoid stress. The suction must have a slight slope of 2% towards the pump.

What type of electrical protection is required?

Use a residual current circuit breaker (RCD) with a residual current not exceeding 30 mA. The power cable must be type H07 RN-F3 with a section suitable for the motor power. Check that the voltage and frequency match the nameplate.

How to prime the pump for the first time?

Remove the prefilter cover, completely fill the pump with water until it comes out of the suction pipe. Replace the basket and close the cover, checking the seal's tightness. Never operate the pump without water to avoid damaging the mechanical seal.

How to check the motor rotation direction?

Observe the rear fan through the fan cover. The rotation direction must be as indicated by the arrow on the pump. If the direction is reversed, swap two power phases (for three-phase) or contact an electrician.

What regular maintenance is required?

Every 100 hours of operation, clean the prefilter basket without knocking it. Check that the power consumption does not exceed the value indicated on the nameplate. In winter or if stopped for a long period, drain the pump via the drain plug to prevent freezing.

What are the wear parts and when to replace them?

Parts that must be replaced periodically are: capacitor, bearings, mechanical seal, and O-rings. Their typical lifespan is 10,000 hours under normal conditions. Replace seals when changing the mechanical seal or bearings.

What to do if the pump does not prime?

Check the tightness of the filter cover and suction piping. Make sure the prefilter is not clogged. Also check the motor rotation direction: if reversed, swap two phases. If the problem persists, consult a technician.

The pump is noisy, what to check?

Check that the pump is properly secured (vibrations). Ensure the prefilter is not clogged and the piping does not have excessive pressure drops. If the noise persists, the motor may be blocked or the mechanical seal defective: contact technical service.

Can the pump be used without supervision?

No, the device is not intended for use by persons (children or adults) without supervision. Children aged 8 and over can use it under supervision if they understand the risks. Always disconnect the pump before any intervention.

How to winterize the pump?

Completely drain the pump by removing the drain plug. Clean the prefilter and basket. Store the pump in a frost-free place. If it remains in place, ensure it is protected against freezing and all fittings are tight.

3. INSTALLATION AND ASSEMBLY

GENERAL

Fit the pump horizontally in order to accommodate 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 parts inside the pump.
- All pumps are fitted with a stand 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 centered in relation to the port to be connected to prevent the pump and the pipe from being subjected to external stress, which 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 below the water level in the pool to improve pump performance.
• 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 unit from the electrical current.

• Use a rigid cable to connect the pump to the mains. If you use a flexible cable to connect it to the mains, it must have cable lugs to connect it to the terminals of the pump's motor.

• Adjust the value of the ground fault circuit interrupter in line with pump intensity.

• Before connecting the motor, check the type of fuse required.
• Check the layout and connection of the ground cable in the unit.
• Respect the electrical installation and connection instructions. Failure to do so may lead to the pump's manufacturer declining all liability and rendering the warranty null and void.
• The installation may be subject to special regulations.
• 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 o 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

- Measurements prior to first start-up:

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's rating plate.

5. Fit the pre-filter cap and screw on tightly, without 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 mode and wait a reasonable time for this to be completed.

5. MAINTENANCE

Depending on the level of water cleanliness, the following should be done every 100 operating hours:

- 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 the consumption in amperes of the motor that is running is equal to or below that indicated on the manufacturer's rating plate. If this information is not 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 housing 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 lists the fungible and / or consumable components of the pump and the period of time in which they must have been replaced.

DESCRIPTION OF THE COMPONENT TIME BETWEEN REPLACEMENTS
Capacitor 10,000 h
Bearings 10,000 h
Mechanical seal 10,000 h
O-rings and other sealing components (1)	10,000 h

(1) The opening and closing of the pump for the replacement of any of the inner spare parts does not guarantee the subsequent sealing. For this reason, it is recommended that the O-rings and sealing components are replaced whenever the mechanical seal and / or bearings are changed.

The estimated working life of the above parts 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.

6. REMOVAL

• The motor unit can be removed from the pump body without having to disconnect the pump's suction and return pipes.
• To remove the motor unit from the pump body, remove the screws that join them together.
