1. Product Overview
The Steinbach Classic 250N Filtration System is a high-performance sand filter designed to maintain clean and clear water in above-ground pools. This powerful unit is suitable for pools with a capacity of up to 19,000 liters, ensuring efficient removal of impurities. It features a robust pump and a versatile 7-way valve for various operational modes.
2. Safety Information
Please read all safety instructions carefully before installation and operation to prevent injury or damage. Keep this manual for future reference.
- Always disconnect the power supply before performing any maintenance or cleaning on the filter system.
- Ensure the electrical outlet is protected by a Ground Fault Circuit Interrupter (GFCI) for safety.
- Do not operate the pump if the water temperature exceeds 35°C (95°F).
- Keep children away from the filter system during operation.
- Ensure all connections are secure and leak-free to prevent water damage or electrical hazards.
- The pump is not self-priming; ensure it is filled with water before starting.
3. Setup and Installation
Proper installation is crucial for the optimal performance of your filtration system. Follow these steps carefully:
3.1 Unpacking and Component Check
Verify that all components are present and undamaged:
- Filter Tank (250 mm diameter)
- Pump Unit (230V / 200W)
- 7-Way Multi-Port Valve with Pressure Gauge
- Connecting Hoses (32/38 mm diameter)
- Base Plate
- Clamps and Fittings
3.2 Filter Media Preparation
The system requires approximately 10 kg of filter sand with a granule size of 0.7 - 1.2 mm, or compatible filter balls. Refer to the specific instructions for filling the filter tank with your chosen media.
3.3 Assembly and Connection
- Place the base plate on a firm, level surface near your pool.
- Mount the filter tank and pump securely onto the base plate.
- Connect the pump to the filter tank and the multi-port valve using the provided hoses and fittings. Ensure all connections are tight to prevent leaks.
- Connect the system to your pool's skimmer and return lines using 32/38 mm hoses.
3.4 Optimal Placement
For gravity-fed operation, the water level in the pool should be above the sand filter. Avoid situations where the water level is below the filter, as this can hinder proper flow and operation.
4. Operating Instructions
The 7-way multi-port valve allows for different operational modes. Always turn off the pump before changing the valve position.
- FILTER: This is the standard operating mode for daily filtration. Water is pumped through the filter media, and clean water is returned to the pool.
- BACKWASH: Used to clean the filter media. Water flows in reverse through the filter, dislodging trapped debris, which is then discharged to waste. Perform when pressure gauge indicates high pressure.
- RINSE: Used after backwashing to flush out any remaining debris from the filter media and lines before returning to FILTER mode. Water is discharged to waste.
- WASTE (EMPTY): Bypasses the filter and pumps water directly out of the pool to waste. Useful for lowering pool water level or vacuuming heavy debris directly to waste.
- RECIRCULATE (CIRCULATE): Bypasses the filter and circulates water directly back to the pool. Useful for distributing chemicals without filtering.
- CLOSED: Closes all flow to the filter. Use only when the pump is off and for maintenance tasks that require isolating the filter.
To start operation, ensure the valve is set to FILTER, then turn on the pump. Monitor the pressure gauge for normal operating pressure.
5. Maintenance
Regular maintenance ensures the longevity and efficiency of your Steinbach filtration system.
5.1 Backwashing and Rinsing
Perform backwashing when the pressure gauge reading is 0.2-0.3 bar (3-5 psi) above the clean filter pressure, or when water flow to the pool decreases significantly. Follow with a rinse cycle.
- Turn off the pump.
- Set the valve to BACKWASH.
- Turn on the pump and backwash until the water in the sight glass (if present) runs clear (typically 2-3 minutes).
- Turn off the pump.
- Set the valve to RINSE.
- Turn on the pump and rinse for 30-60 seconds.
- Turn off the pump.
- Set the valve back to FILTER.
- Turn on the pump to resume normal filtration.
5.2 Filter Media Replacement
Filter sand typically needs replacement every 3-5 years, depending on usage and water quality. Filter balls may require periodic cleaning or replacement as per their specific instructions.
5.3 Winterization
Before freezing temperatures, drain all water from the pump, filter tank, and hoses. Store the pump and valve in a dry, frost-free location. Cover the filter tank if it remains outdoors.
6. Troubleshooting
Refer to this section for common issues and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water flow / Poor filtration | Clogged filter media; Clogged skimmer/pump basket; Air in system; Incorrect valve setting. | Perform backwash/rinse; Clean skimmer/pump basket; Bleed air from system; Set valve to FILTER. |
| High pressure gauge reading | Dirty filter media. | Perform backwash and rinse cycle. |
| Water leaking from valve/connections | Loose connections; Damaged O-rings/gaskets. | Tighten connections; Inspect and replace O-rings/gaskets if necessary. |
| Pump not priming | Pump not filled with water; Air leak on suction side; Clogged impeller. | Fill pump with water; Check all suction side connections for leaks; Inspect and clear impeller. |
