2. Product Overview and Components
The ASTRALPOOL Aster 99 Sand Filter is designed for efficient swimming pool water filtration. It consists of a durable filter tank and a multi-port valve that controls the water flow through the system.
Figure 1: ASTRALPOOL Aster 99 Sand Filter and Multi-port Valve. The image displays the main filter tank, which is a large, white, spherical unit, alongside a separate black multi-port valve with a handle, used for directing water flow.
2.1. Main Components:
- Filter Tank: The main body where the filter media (sand) is contained.
- Multi-port Valve: Controls the operational modes of the filter (e.g., filter, backwash, rinse).
- Pressure Gauge: Indicates the internal pressure of the filter, crucial for determining when backwashing is needed.
- Drain Plug: Located at the bottom of the tank for draining water.

4. Setup and Installation
Proper installation is crucial for the filter's performance and longevity. Follow these steps carefully.
4.1. Site Selection
- Place the filter on a firm, level surface, preferably concrete, to prevent settling.
- Ensure adequate ventilation and protection from direct sunlight and freezing temperatures.
- Allow sufficient space around the filter for maintenance and service.
4.2. Filling with Filter Media (Sand)
- Ensure the internal standpipe and laterals are properly assembled and secured.
- Place a plastic bag or cover over the standpipe opening to prevent sand from entering.
- Carefully pour the recommended amount and grade of filter sand into the tank.
- Remove the plastic bag/cover and ensure no sand has entered the standpipe.
4.3. Multi-port Valve Installation
- Carefully place the multi-port valve onto the filter tank, aligning the standpipe with the valve's opening.
- Secure the valve to the tank using the provided clamp or bolts, ensuring a tight seal.
- Connect the plumbing from the pump to the "PUMP" port on the valve.
- Connect the plumbing to the pool return lines to the "RETURN" port on the valve.
- Connect a waste line to the "WASTE" port on the valve, directing water to an appropriate drainage area.
- Install the pressure gauge into the designated port on the valve.
5. Operating Instructions
The multi-port valve controls the filter's functions. Always turn off the pump before changing the valve position to prevent damage.
5.1. Multi-port Valve Positions
- FILTER: Normal filtering mode. Water flows through the sand, is cleaned, and returned to the pool.
- BACKWASH: Cleans the filter sand. Water flows in reverse, flushing trapped debris out the waste line.
- RINSE: Used after backwashing to settle the sand and flush any remaining dirty water to waste before returning to FILTER mode.
- WASTE/DRAIN: Bypasses the filter, sending water directly from the pool to the waste line. Useful for vacuuming heavy debris or lowering pool water level.
- RECIRCULATE: Bypasses the filter, circulating water directly back to the pool. Useful for chemical distribution without filtering.
- CLOSED: Shuts off all flow to the filter. Use for servicing the pump or filter.
5.2. Initial Startup (First Backwash)
- Ensure the pool is filled to the proper level and all plumbing connections are secure.
- Set the multi-port valve to BACKWASH.
- Turn on the pump. Backwash for 2-3 minutes, or until the water in the sight glass (if present) runs clear.
- Turn off the pump.
- Set the multi-port valve to RINSE.
- Turn on the pump. Rinse for 30-60 seconds.
- Turn off the pump.
- Set the multi-port valve to FILTER.
- Turn on the pump. Note the initial pressure gauge reading; this is your clean filter pressure.
6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your filter.
6.1. Backwashing
Backwash the filter when the pressure gauge reading is 8-10 PSI (0.5-0.7 bar) above the clean filter pressure, or when pool water clarity decreases. Follow the steps outlined in "5.2. Initial Startup (First Backwash)" for each backwash cycle.
6.2. Winterization (if applicable)
- Turn off the pump and disconnect power.
- Set the multi-port valve to WINTERIZE (if available) or an intermediate position between two settings to relieve pressure on the gasket.
- Remove the drain plug at the bottom of the filter tank to completely drain all water.
- Disconnect all plumbing lines and store them in a dry, frost-free area.
- Remove the pressure gauge and store it indoors.
- Cover the filter to protect it from elements.
7. Troubleshooting
This section addresses common issues you might encounter with your sand filter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water flow / High pressure | Clogged filter sand; pump strainer basket full; closed valve. | Backwash the filter; clean pump strainer basket; check valve position. |
| Cloudy pool water | Insufficient filtration time; dirty filter sand; improper chemical balance; damaged laterals. | Increase filtration time; backwash/rinse filter; test and adjust pool chemistry; inspect laterals for damage. |
| Water leaking from valve | Worn spider gasket; loose connections. | Replace spider gasket; tighten connections. |
| Sand returning to pool | Damaged laterals; too much sand; improper sand grade. | Inspect and replace damaged laterals; ensure correct sand level and grade. |
