📏 Pool Sizing Guide

The Hayward ProSeries HB S210TXE filter is designed to handle medium to large residential pools. Proper filter sizing ensures optimal water quality and energy efficiency.

Sizing Principle:

The filter flow rate should turn over the entire pool volume within 6-8 hours for optimal filtration. A 6-hour turnover provides excellent water quality, whilst 8 hours represents the maximum recommended period.

Formula:

Required Flow Rate (m³/h) = Pool Volume (m³) ÷ Turnover Time (hours)

Pool Size Compatibility Table:

Pool Type	Volume Range	Turnover Time	Suitability
🏠 Medium Above-Ground	30,000 – 50,000 L	5-6 hours	✅ Excellent – Optimal performance
🏠 Large Above-Ground	50,000 – 60,000 L	6 hours	✅ Excellent – Perfect match
🏊 Small In-Ground	40,000 – 60,000 L	4-6 hours	✅ Excellent – Strong performance
🏊 Medium In-Ground	60,000 – 80,000 L	6-8 hours	✅ Good – Maximum capacity
🏊 Large In-Ground	Over 80,000 L	8+ hours	⚠️ Consider larger S244TXE model

This Filter Performance:

📍 Flow Rate: 10 m³/h (10,000 litres per hour)

📍 Optimal Pool Size: Up to 60,000 litres (6-hour turnover)

📍 Maximum Pool Size: Up to 80,000 litres (8-hour turnover)

💡 Sizing Tip: For heavily used pools or those with high debris exposure (near trees, frequent swimmers), select a filter that achieves 6-hour turnover for best results.

🛠️ Installation Requirements

Plumbing Connections

Requirement	Specification
Inlet Connection	1½” (38mm) BSP
Outlet Connection	1½” (38mm) BSP
Valve Position	Top Mount
Waste Connection	1½” (38mm) to drain

Physical Installation

Requirement	Details
Base Surface	Solid, level concrete pad or stable base
Clearance Above	Minimum 650 mm for valve operation and media access
Clearance Around	Minimum 450 mm all sides for maintenance
Maximum Height Above Water	1.5 metres from filter top to pool water level

Pump Compatibility

⚠️ Important: The filter must be matched with an appropriately sized pump for optimal performance.

🔄 Maintenance Guide

Routine Maintenance Schedule

Task	Frequency	Procedure
Check Pressure Gauge	Weekly	Note reading; compare to clean baseline
Inspect Pump Strainer	Weekly	Clear debris; ensure good water flow
Backwash Filter	When pressure rises 0.7 bar above baseline	Run until sight glass shows clear water (2-3 minutes)
Rinse After Backwash	After each backwash	30-60 seconds to settle media
Inspect Seals & O-Rings	Seasonally	Replace if worn, cracked or leaking
Check Media Level	Annually	Top up if settled below 2/3 mark
Full Media Change	Every 5-7 years (sand) / 10+ years (glass)	Replace completely

Pressure Gauge Reference Guide

Reading	Status	Action Required
📊 0.5 – 0.8 bar	Clean filter baseline	Normal operation
📊 0.8 – 1.1 bar	Normal operating range	Continue monitoring
📊 1.2 – 1.3 bar (0.7 bar above baseline)	Backwash required	Perform backwash cycle
📊 Above 1.3 bar	Overdue for backwash	Immediate backwash required
📊 3.5 bar	Maximum safe pressure	Stop pump immediately; investigate

Winterisation Procedure (UK Climate)

Proper winterisation is essential to protect your filter from frost damage during the colder months:

1. Drain Filter Tank Completely – Remove the drain plug at the base of the tank and allow all water to evacuate
2. Leave Drain Plug Removed – Do not reinstall the drain plug during winter months
3. Position Valve Handle – Set the multiport valve handle between positions or to “WINTER” position if available
4. Cover or Store – If possible, cover the filter or store in a frost-free location
5. Protect Plumbing – Drain all connecting pipework to prevent ice damage

⚠️ Critical: Never leave water in the filter tank during freezing conditions. Ice expansion can crack the tank and void your warranty.

🪨 Filter Media Information

The Hayward ProSeries HB S210TXE is designed for use with high-quality filter sand or alternative media for enhanced filtration performance.

Compatible Media Types

Media Type	Filtration Rating	Typical Lifespan	Key Benefits
Silica Sand	20-40 microns	5-7 years	Economical, widely available, proven performance
Glass Media	5-15 microns	10+ years	Finer filtration, reduced backwash frequency, eco-friendly
ZeoSand/Zeolite	3-5 microns	5 years	Superior clarity, ammonia reduction, water polishing

Media Requirements

Specification	Requirement
Total Capacity	100 kg
Recommended Grain Size	0.4 – 0.8 mm (Grade 16 silica sand)
Fill Level	Sand should reach approximately ⅔ of tank height when levelled

Signs Your Filter Media Needs Replacing

• 💧 Poor water clarity despite correct chemical balance
• ⏱️ Shortened filter cycles between backwashes
• 🌊 Cloudy water returning to pool after filtration
• 📈 Persistently high pressure readings even after backwashing
• 🔬 Visible channelling or clumping in the media bed

💡 Upgrade Tip: Consider switching from sand to glass media for improved filtration (5-15 microns vs 20-40 microns), reduced backwash water consumption, and extended media lifespan.

🔬 Filtration Performance

The Hayward ProSeries HB S210TXE delivers reliable filtration performance through proven high-rate sand filter technology.

Performance Metric	Specification
Filtration Rating (Sand)	40-50 microns
Filtration Rating (Glass Media)	5-15 microns
Filter Area	0.20 m²
Design Flow Rate	10 m³/h
Pressure Loss at Design Flow	0.14 bar

Micron Rating Explained

Rating	Particle Size	What It Captures
50+ microns	Visible to naked eye	Leaves, large debris, insects
40-50 microns	Fine visible particles	Sand, dirt, hair, visible particles
20-40 microns	Barely visible	Fine dirt, some algae, small debris
10-20 microns	Not visible	Very fine particles, most algae
5-10 microns	Microscopic	Ultra-fine particles, nearly all algae

💡 Performance Note: The S210TXE’s 40-50 micron filtration with standard sand is excellent for typical residential use. For enhanced water clarity, glass media reduces this to 5-15 microns.

⚙️ Valve Positions & Functions

The Vari-Flo™ 6-position multiport valve provides complete control over your filtration system:

Position	Symbol	Function	When to Use
FILTER	F	Normal filtration mode	Daily operation (10-14 hours per day)
BACKWASH	B	Reverses water flow to clean media	When pressure rises 0.7 bar above baseline
RINSE	R	Settles media after backwashing	30-60 seconds after each backwash
WASTE	W	Bypasses filter to drain	Lowering water level; vacuuming heavy debris
RECIRCULATE	C	Bypasses filter, returns to pool	Chemical distribution; shock treatment
CLOSED	X	Stops all water flow	When servicing pump or filter

⚠️ Critical Safety Warning: ALWAYS stop the pump before changing valve positions. Operating the valve with the pump running can cause serious damage to equipment and personal injury.

❓ Frequently Asked Questions

Q: What size pool will this filter handle?

A: The S210TXE is suitable for pools up to 80,000 litres with an 8-hour turnover, or up to 60,000 litres for optimal 6-hour turnover. With a flow rate of 10 m³/h, it processes 10,000 litres per hour.

Q: How often do I need to backwash?

A: Backwash when the pressure gauge reads approximately 0.7 bar (10 PSI) above your clean filter baseline. This typically occurs every 1-2 weeks during the swimming season, depending on pool usage and debris levels.

Q: What filter media should I use?

A: The filter is designed for 0.4-0.8mm grade sand (100 kg capacity). You can also use glass media or ZeoSand for improved filtration performance. Glass media offers 5-15 micron filtration versus 40-50 microns with sand.

Q: How long does filter media last?

A: Standard silica sand typically lasts 5-7 years before requiring replacement. Glass media can last 10+ years. ZeoSand typically requires replacement every 5 years.

Q: What pump do I need?

A: Match with a pump delivering 6-10 m³/h for optimal performance. Never exceed the filter’s maximum flow rate of 10 m³/h. Variable-speed pumps offer excellent flexibility and energy efficiency.

Q: Is this filter saltwater compatible?

A: Yes, the blown polyethylene tank is specifically designed to resist corrosion from saltwater chlorination systems.

Q: What warranty is included?

A: Hayward provides a 5-year warranty on the tank and a 3-year warranty on equipment (valve, laterals, etc.). Contact Parts4Tubs for full warranty terms and conditions.

Q: Can this filter be installed outdoors?

A: Yes, the weather-resistant construction is designed for permanent outdoor installation. However, proper winterisation is essential in the UK climate to prevent frost damage.

Q: How much clearance do I need above the filter?

A: A minimum of 650mm clearance above the filter is required to allow proper valve operation and access for media inspection or replacement.

Q: What’s included with the filter?

A: The S210TXE includes the filter tank, top-mounted Vari-Flo™ 6-position multiport valve, pressure gauge, mounting base, and all necessary internal components. Filter media (sand/glass) is not included.
