📐 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:

Pool Volume (litres) = Flow Rate (m³/hr) × Turnover Time (hours) × 1000

This Package Specifications

📍 Filter Flow Rate: 19 m³/hr
📍 6-Hour Turnover Capacity: Up to 114,000 litres
📍 8-Hour Turnover Capacity: Up to 152,000 litres

Pool Size Compatibility

Pool Type	Volume Range	Suitability
🏊 Large above-ground	50,000-80,000 L	✅ Excellent – Fast turnover
🏠 Medium in-ground	60,000-90,000 L	✅ Excellent – Optimal performance
🏠 Large in-ground	90,000-114,000 L	✅ Excellent – 6-hour turnover
🏠 Very large in-ground	114,000-152,000 L	✅ Good – 8-hour turnover

🧹 Maintenance Guide

Routine Maintenance Schedule

Task	Frequency	Details
Check pressure gauge	Weekly	Record baseline and monitor increase
Inspect pump strainer basket	Weekly	Clean debris, check for damage
Backwash filter	When required	When pressure rises 0.5-1.0 bar above baseline
Rinse after backwash	After each backwash	Run for 30-60 seconds
Inspect pump lid O-ring	Monthly	Lubricate with silicone grease
Check filter lid seal	Monthly	Replace if worn or cracked
Inspect media level	Annually	Top up if required
Full media replacement	Every 5-7 years	Replace with fresh filter sand

Pressure Gauge Guide

📊 Clean Filter Baseline: 0.5-1.0 bar (typical)
📊 Backwash Required: 0.5-1.0 bar above baseline
📊 Maximum Safe Operating Pressure: 2.5 bar

Visual Monitoring Advantage

💡 Top Mount Benefit: The clear valve mounting ring allows you to visually confirm:

• Water clarity during filtration
• Debris removal during backwashing
• When backwash cycle is complete (water runs clear)
• Proper rinse cycle operation

Backwash Procedure

1. Turn off pump – Always switch off before adjusting valve
2. Set valve to BACKWASH – Rotate multiport valve handle
3. Turn on pump – Watch through clear ring until water runs clear (2-4 minutes typical)
4. Turn off pump – Switch off before changing valve position
5. Set valve to RINSE – Settle the filter media
6. Turn on pump – Run for 30-60 seconds
7. Turn off pump – Switch off before returning to filter mode
8. Set valve to FILTER – Return to normal operation
9. Turn on pump – Resume normal filtration

💡 Tip: The powerful 1.5HP pump provides excellent backwash flow. With 200kg of media, allow slightly longer backwash times to ensure thorough cleaning.

Winterisation (UK Climate)

❄️ Essential Steps for Frost Protection:

1. Switch off pump and isolate electrical supply
2. Set multiport valve to WINTERISE or CLOSED position
3. Remove drain plug from filter tank base
4. Drain all water from filter tank completely
5. Remove pump lid and drain pump housing
6. Remove drain plugs from pump (if fitted)
7. Store all drain plugs safely for spring
8. Cover filter and pump or relocate to frost-free storage
9. Disconnect and drain all pipework where possible

⚠️ Never leave water in filter or pump during freezing conditions – ice expansion can crack tanks and housings.

❓ Frequently Asked Questions

Q: What size pool will this package handle?

A: This high-performance system is suitable for pools up to 152,000 litres with an 8-hour turnover, or up to 114,000 litres for a 6-hour turnover. This covers large residential pools and some smaller commercial applications.

Q: What’s the advantage of top mount over side mount?

A: The top mount configuration features a unique clear valve mounting ring that allows you to visually monitor water clarity during filtration and see when backwashing is complete. The design also offers a more compact footprint compared to side mount configurations.

Q: Is this package suitable for saltwater pools?

A: Yes, both the Vision filter and Aquaspeed pump are fully compatible with salt chlorination systems. The pump features a 316 stainless steel mechanical seal specifically designed for salt pool applications.

Q: How often do I need to backwash the filter?

A: Backwash when the pressure gauge reads 0.5-1.0 bar above your clean filter baseline reading, or when you notice reduced water clarity through the clear valve ring. With the large 200kg media capacity, backwash cycles may be less frequent than smaller filters.

Q: What filter media is included?

A: This package includes 200 kg of filter grade silica sand. The filter is also compatible with glass media and ZeoSand alternatives if you prefer finer filtration.

Q: How long does the filter sand last?

A: Filter sand typically lasts 5-7 years before requiring replacement. Glass media can last 10+ years and provides finer filtration.

Q: Can I replace the sand with glass media?

A: Yes, the Vision filter is fully compatible with glass filter media. Glass requires approximately 30% less by weight (around 140 kg for this filter), offers finer 5-15 micron filtration, and lasts significantly longer than sand.

Q: What warranty is included?

A: The Vision filter tank carries an impressive 10-year warranty for residential installations. The Aquaspeed pump has a 2-year limited warranty (1 year on mechanical seal and capacitor).

Q: Is this compatible with my existing pipework?

A: The filter uses standard 1.5″/50mm connections with quick connect unions included. The 1.5HP pump has 2″ connections for both suction and delivery, which may require adaptation for some existing installations.

Q: Can I use this filter with Baquacil?

A: No, Vision filters are NOT suitable for use with Baquacil products. Use only with chlorine, salt chlorination, or bromine sanitisation systems.

Q: What electrical supply do I need?

A: The 1.5HP Aquaspeed pump requires a 220-240V single phase supply. It comes with approximately 1.5 metres of pre-wired cable. All electrical installation must be carried out by a qualified electrician.

Q: How does this compare to the 24″ Vision filter?

A: The 28″ FVS30T offers significantly more capacity: 0.38 m² filter area (vs 0.28 m²), 19 m³/hr flow rate (vs 14 m³/hr), and 200kg sand capacity (vs 160kg). This makes it better suited for larger pools or installations with higher filtration demands.
