Q: What is the replacement seal for the filter cover of the SENA pump?

The SENA manual does not provide a specific part reference for the filter cover seal. However, it confirms that this seal is an important maintenance item: you should regularly clean the impurities from the seal support to ensure the tightness of the pre-filter cover. According to the manual, the seal is part of the wear parts with a lifespan of 10,000 hours of use. It particularly recommends replacing the O-rings when changing the mechanical seal or bearings . To find the right seal: Contact AstralPool directly (manufacturer) with your SENA model number - they can provide you with the exact reference and dimensions of the seal. Check the nameplate of your pump or the original casing: a list of spare parts is often attached there. Consult an authorized AstralPool dealer or a local pool store - they usually have parts catalogs in stock and know the common references for this model. Describe the seal (diameter, thickness, rubber material) to your supplier: standard seals for pool pumps come in various sizes. Important: The manual states that "opening and closing the pump for the replacement of one of the spare parts does not guarantee subsequent tightness." Have the seal replaced by a professional if you are not sure, or replace it with any new mechanical seal to ensure permanent tightness.

Q: Can the SENA pump operate continuously without risk?

Yes, the SENA pump is designed for continuous operation , provided that the recommended operating conditions are respected. This high-efficiency motor filtration pump is intended for prolonged use. According to the manual, the consumable components (capacitor, bearings, mechanical seal, gaskets, and sealing elements) have a lifespan of 10,000 hours . This is the recommended interval for their preventive replacement to keep the pump in good condition. Essential conditions for continuous operation without damage: Water temperature : do not exceed 35°C Water quality : it must be clean and properly filtered Installation : horizontal position required (important for the pre-filter) Maintenance : replace wear parts after 10,000 hours of operation As long as these parameters are respected, your SENA pump can run 24/7 without issue. Stable water temperature and regular maintenance of the pre-filter are key to extending its lifespan.

Question 1

Why does my Praga filter indicate high pressure and leak water from the lid?

Accepted Answer

A high pressure combined with a leak at the lid generally indicates that the filter needs urgent cleaning.

Causes and solutions

1. Clogging of the sand bed (main cause)

According to the specifications of the Praga filter, cleaning should begin as soon as the pressure difference between the inlet and outlet reaches 0.6 bar. If you have not done this and the pressure continues to rise to 0.8 bar or more, the sand is heavily clogged.

Stop the pump immediately
Switch the filter to Washing mode for 3-5 minutes until the drainage water becomes clear
Then, if your system has a rinsing function (5 valve model), start the rinsing for 2 minutes
Restart in Filtration mode

2. Leak at the lid

The leak may be caused by:

Worn sealing gasket: Inspect the rubber gasket around the lid. If it is hardened, cracked, or flattened, it needs to be replaced.
Loose lid: Check that all the bolts are tightened properly, but without forcing (risk of breaking the polyester).
Excessive internal pressure: A pressure that does not drop after complete washing can create internal buildup that forces water to escape. This confirms that the cleaning was insufficient.

Note: To avoid these problems, maintain a regular cleaning schedule by monitoring the pressure gauges. The Praga filter is designed for filtration rates of 40 m³/h/m² (residential) or 20 m³/h/m² (public). A rapidly increasing pressure indicates either too high a flow rate or clogged sand.

Maintenance of the Pump Body

Check the fastening of the mechanical parts and the condition of the assembly screws
Monitor the temperature of the motor and pump during operation
Watch for abnormal vibrations that could indicate wear
Drain the pump before winter by removing the drain plug #10
Each time you open the body, clean the impurities around the seal support to ensure tightness

Parts to Replace

For optimal maintenance, plan to replace the following parts approximately once a year:

Seals and sealing elements
Mechanical closure
Bearings

These regular replacements ensure the tightness and reliability of your pump over time.

Question 4

How to unlock the control panel of the Equilibre E spa?

Question 5

What amount of silica sand is needed for the ASTRALPOOL Millennium 26-inch filter?

Accepted Answer

For the ASTRALPOOL Millennium 26-inch filter, you need approximately 50 kg of silica sand with a grain size of 0.5 to 0.7 mm.

Filling Procedure

Position the filter and make the plumbing connections
Remove the cover and the gasket
Fill the filter halfway with water
Pour the required amount of sand (50 kg) inside
Clean the gasket housing
Replace and tighten the cover

After Filling

You must perform an initial wash: set the multiport valve to WASH, open the suction valves, and run the pump for 4 minutes before switching to FILTERING mode.

Maintenance

The manual recommends replacing the sand approximately every 3 years and cleaning it annually with Filnet Astral (solid or liquid) for optimal performance.

Question 6

How to remove or change the cover of the ASTRALPOOL Millennium filter with its zuncho?

Accepted Answer

To remove the cover of the ASTRALPOOL Millennium filter, you first need to loosen the zuncho (plastic tightening collar) that holds the lid securely in place. Make sure the pump is off and the filter is not under pressure before undertaking this operation.

Proceed in several steps. Start by locating the zuncho located all around the edge of the lid, then turn it counterclockwise to gradually loosen it. Once completely unlocked, gently lift the lid upwards by pulling straight. You will then need to remove the sealing gasket located under the lid.

Before replacing the lid, carefully clean the groove of the gasket to avoid leaks when closing. For the exterior cleaning of the lid, never use chemical solvents, as they would damage the transparency and shine properties of the plastic. A simple damp cloth is sufficient.

Once your maintenance or sand filling operations are complete, replace the sealing gasket in its groove, ensuring it is well positioned over the entire surface. Then, place the lid back on the filter and tighten the zuncho firmly by turning it clockwise until a good seal is achieved, without forcing it to avoid breaking the plastic parts.

This procedure is particularly necessary when initially filling the filter with 50 kg of silica sand (grain size 0.5-0.7 mm), during the annual sand cleaning, or during winterization. During winterization, you must leave the lid removed to ensure proper ventilation of the filter during its inactive period.

Question 7

How to unlock or defrost the control panel of the Emotion E spa?

Accepted Answer

To unlock the control panel of your ASTRALPOOL Emotion E spa:

Question 10

How to program a time slot with a temperature of 35°C on the Swimspa CRETA?

Accepted Answer

The Swimspa CRETA allows you to manage heating schedules through two complementary modes:

Option 1 - REST Mode (recommended)

The REST mode heats the water only during the programmed filtration cycles. To program 12pm-3pm at 35°C:

Select Cycle 1 or activate Cycle 2
Set the start time to 12pm
Set the duration to 3 hours (180 minutes, in increments of 15 minutes)
Set the target temperature to 35°C (press the temperature up/down button)

The manual specifies that you can adjust the start time and duration in 15-minute increments.

Option 2 - READY Mode

The READY mode maintains a constant temperature with polling every 30 minutes. You can program the temperature to 35°C and activate it manually during your time slot (12pm-3pm).

Location of settings: Refer to your TP600 panel (physical buttons) or touch panel (LED screen) depending on your equipment. The programming settings can be found in the cycle configuration menus.
