📏 Pool Sizing Guide

Sizing Principle: The filter flow rate should turn over the entire pool volume within 6-8 hours for optimal water clarity and hygiene.

Formula:

Maximum Pool Volume = Flow Rate × Turnover Time
9 m³/hr × 6 hours = 54,000 litres (optimal)
9 m³/hr × 8 hours = 72,000 litres (maximum)

Pool Size Compatibility

Pool Type	Volume Range	Suitability
🏊 Small above-ground	Up to 20,000 L	✅ Excellent – rapid turnover
🏊 Medium above-ground	20,000-40,000 L	✅ Excellent – efficient filtration
🏊 Large above-ground	40,000-54,000 L	✅ Good – 6-hour turnover
🏡 Small in-ground	Up to 40,000 L	✅ Excellent – ideal match
🏡 Medium in-ground	40,000-54,000 L	✅ Good – recommended maximum
🏡 Large in-ground	54,000+ L	⚠️ Consider larger filter/pump

This Package:

📍 Filter Flow Rate: 9 m³/hr
📍 Pump Flow Rate: 10.1 m³/hr @ 10m head
📍 Recommended for pools up to: 54,000 litres
📍 Maximum pool capacity: 72,000 litres (with 8-hour turnover)

🔄 Maintenance Guide

Routine Maintenance

Task	Frequency	Procedure
Check pressure gauge	Weekly	Normal operating range: 0.5-1.5 bar
Empty pump strainer basket	Weekly	Remove debris, inspect seal condition
Backwash filter	When pressure rises 0.5-1 bar above baseline	Until sight glass runs clear (2-3 minutes)
Rinse after backwash	After each backwash	30-60 seconds to settle media
Inspect filter seals	Start/end of season	Replace if worn or damaged
Check sand level	Annually	Top up if below recommended level
Full sand replacement	Every 5-7 years	Replace all 90kg of filter media

Pressure Gauge Guide

📊 Clean filter baseline: 0.5-1.0 bar (varies by installation)
📊 Backwash required: When 0.5-1 bar above baseline
📊 Maximum safe operating pressure: 2.5 bar
⚠️ Never exceed 2.5 bar working pressure

Using the Transparent Valve Ring

The FVS20T’s clear valve mounting ring allows you to:

• Monitor water clarity during filtration
• Observe backwash effectiveness in real-time
• Confirm when backwash cycle is complete (water runs clear)
• Spot any issues early before they become problems

Winterisation (UK Climate)

For protection during freezing UK winters:

1. Filter Tank – Drain completely via drain plug; store plug safely
2. Multiport Valve – Position handle between settings to prevent seal compression
3. Pump – Drain pump body completely; remove all drain plugs
4. Strainer Basket – Remove, clean thoroughly, and store dry
5. Pipework – Drain all connecting pipes; use antifreeze in exposed sections if needed
6. Protection – Cover equipment or store in frost-free location where possible

⚠️ Critical: Never leave water in filter tank or pump during freezing conditions – ice expansion causes irreparable damage

💧 Filter Media Information

Compatible Media Types

Media Type	Filtration Rating	Lifespan	Key Benefits
Silica Sand (Grade 16)	20-40 microns	5-7 years	Cost-effective, proven reliability
Glass Media	5-15 microns	10+ years	Superior clarity, eco-friendly, longer lasting
ZeoSand/Zeolite	3-5 microns	5 years	Finest filtration, ammonia removal

Media Capacity: 90 kg

Recommended Sand Grade: 16/30 grade silica sand (0.4-0.8mm grain size)

Signs Filter Media Needs Replacing

• Persistent cloudy water despite correct chemical balance
• Shortened filter cycles between backwashes
• Murky water returning to pool after filtration
• Increased chemical consumption for same results
• Sand particles appearing in pool (may indicate lateral damage)

💎 Filtration Performance

Metric	Value
Filter Area	0.20 m²
Filtration Rating (Sand)	20-40 microns
Filtration Rating (Glass)	5-15 microns
Flow Rate	9 m³/hr

Micron Rating Guide

Rating	What It Removes
40+ microns	Visible debris, leaves, large particles
20-40 microns	Sand, dirt, visible particles, hair
10-20 microns	Fine particles, some algae, pollen
5-10 microns	Very fine particles, most algae, bacteria clumps

💡 Pro Tip: Switching to glass media delivers 5-15 micron filtration without replacing your filter tank – a cost-effective upgrade for noticeably clearer water.

🔧 Multiport Valve Positions & Functions

Position	Function
Filter	Normal filtration – water passes through sand and returns clean to pool
Backwash	Reverses water flow to flush trapped debris to waste
Rinse	Settles sand after backwash and clears residual debris
Waste	Bypasses filter, drains water directly to waste (ideal for vacuuming heavy debris)
Recirculate	Bypasses filter, returns water directly to pool (for chemical distribution)
Closed	Stops all water flow through valve

⚠️ Important: Always switch off pump before changing valve position to prevent damage to internal seals and components.

🤔 Frequently Asked Questions

Q: What size pool will this filter and pump handle? A: This package suits pools up to 54,000 litres with a 6-hour turnover, or up to 72,000 litres with an 8-hour turnover. The filter flow rate is 9 m³/hr, well matched with the pump output at typical operating conditions.

Q: What’s the difference between top mount and side mount filters? A: The top mount (FVS20T) has the multiport valve positioned on top with a transparent mounting ring for viewing filtration. The side mount has the valve on the side with a clear lid on top. Top mount offers easier valve access; side mount may suit tighter overhead spaces.

Q: How often do I need to backwash the filter? A: Backwash when the pressure gauge reads 0.5-1 bar above your clean baseline. This typically occurs every 1-2 weeks during swimming season, depending on usage and debris levels.

Q: What filter media should I use? A: The filter accepts 90kg of Grade 16 silica sand (20-40 micron filtration). For enhanced clarity, consider glass media (5-15 microns) or ZeoSand (3-5 microns) at equivalent volumes.

Q: How long does the sand last? A: Silica sand typically provides 5-7 years of service before replacement is needed. Glass media can last 10+ years. Replace when water clarity deteriorates despite proper maintenance.

Q: Is this package suitable for salt chlorinated pools? A: Yes, both the Vision filter and Euroswim pump are approved for use with salt water chlorination systems.

Q: How quiet is the pump? A: The Euroswim operates at just 53-64 LpA – among the quietest pool pumps available. It can be installed near outdoor living spaces without causing noise disturbance.

Q: What warranty is included? A: The Vision filter tank carries a 10-year warranty for residential installations, with 1 year on components. The Euroswim pump has manufacturer warranty coverage – contact Parts4Tubs for complete terms.

Q: Can I use Baquacil sanitiser with this filter? A: No. Vision filters are NOT compatible with Baquacil (PHMB) sanitiser systems. Use chlorine, bromine, or salt chlorination only.

Q: What electrical supply does the pump require? A: The EUP051 requires a 220V single-phase electrical supply. Always use a qualified electrician for installation.
