📐 Pool Sizing Guide

Sizing Principle: The filter flow rate should turn over the entire pool volume within 6-8 hours for optimal water quality. A 6-hour turnover provides excellent filtration for most residential pools, whilst 8 hours represents the maximum recommended cycle time.

Formula:

Pool Volume (litres) = Flow Rate (m³/h) × Turnover Time (hours) × 1,000

Pool Size Compatibility:

Pool Type	Volume Range	Suitability
🏠 Medium Above-Ground	20,000-40,000 L	Excellent – optimal turnover in 2-4 hours
🏠 Large Above-Ground	40,000-60,000 L	Very Good – ideal 4-6 hour turnover
🏊 Small In-Ground	Up to 50,000 L	Excellent – comfortable 5-hour turnover
🏊 Medium In-Ground	50,000-60,000 L	Very Good – optimal 6-hour turnover
🏊 Large In-Ground	60,000-80,000 L	Good – 6-8 hour turnover achieved

This Filter:

📍 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)

💡 Tip: For pools at the upper capacity limit, consider running the filter for longer daily periods during peak summer months to maintain optimal water clarity.

🔄 Maintenance Guide

Routine Maintenance Schedule:

Task	Frequency	Procedure
Check pressure gauge	Weekly	Record baseline pressure; note changes
Backwash filter	When pressure rises 0.3-0.5 bar above baseline	Until sight glass runs clear (typically 2-3 minutes)
Rinse after backwash	After each backwash	Run for 30-60 seconds to settle media
Inspect valve seals	Every 3-6 months	Check for leaks; replace if worn
Check media level	Annually	Top up if media has compacted
Full media inspection	Every 3-5 years	Check for channelling or clumping
Media replacement	Every 10+ years (glass)	Replace if water clarity declines

Pressure Gauge Guide:

📊 Clean Filter Baseline: 0.5-0.8 bar (record your specific baseline after installation)

📊 Backwash Required: When pressure rises 0.3-0.5 bar above baseline

📊 Maximum Safe Operating Pressure: 1.3 bar

📊 Absolute Maximum Pressure: 3.5 bar (tank rating – never operate at this level)

⚠️ Warning: If pressure exceeds 1.3 bar regularly, check for blockages in the return pipework or consider whether the pump is oversized for the filter.

Winterisation (UK Climate):

Proper winterisation is essential to prevent freeze damage during UK winters:

1. Turn off the pump and close all valves
2. Set multiport valve to “Winterise” position or between settings
3. Remove the drain plug at the base of the tank
4. Allow all water to drain completely from the filter
5. Remove the pressure gauge if possible, or protect from frost
6. Store the drain plug safely – do not lose it
7. Cover the filter with a weatherproof cover or tarpaulin
8. Never leave water in the filter during freezing conditions

💡 Tip: Glass media does not absorb water like sand, making it naturally more resistant to freeze-thaw damage, but complete drainage is still essential.
