📐 Pool Sizing Guide

The Waterco Exotuf E500 is designed for small to medium residential pools. For optimal water quality, the filter should turn over the entire pool volume within 6 to 8 hours.

Sizing Formula:

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

Pool Size Compatibility:

Pool Type	Volume Range	Suitability
🏊 Small above-ground	Up to 20,000 L	✅ Excellent – ample headroom
🏊 Medium above-ground	20,000 – 40,000 L	✅ Excellent – ideal match
🏊 Large above-ground	40,000 – 56,500 L	✅ Good – at capacity
🏠 Small in-ground	Up to 40,000 L	✅ Excellent – well matched
🏠 Medium in-ground	40,000 – 56,500 L	✅ Good – at optimal capacity
🏠 Large in-ground	56,500+ L	⚠️ Consider E600 model

This Filter:

• 📍 Maximum Flow Rate: 9.4 m³/hr (157 lpm)
• 📍 Suitable for pools up to: 56,500 litres (based on 6-hour turnover)
• 📍 Optimal for pools: 25,000 – 45,000 litres

⚙️ Installation Requirements

Plumbing Connections

Requirement	Specification
Inlet Connection	40mm
Outlet Connection	40mm
Valve Position	Top Mount
Barrel Unions	Quick-connect included

Physical Installation

Requirement	Details
Base	Solid, level surface required
Clearance Above	Minimum 350mm for valve operation and media access
Clearance Around	Minimum 250mm for maintenance and plumbing access
Location	Outdoor installation suitable – UV resistant

Pump Compatibility

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

• Recommended pump flow rate: 6 – 9.4 m³/hr
• Minimum backwash flow: 131 lpm (7.9 m³/hr)
• Maximum flow rate: Do not exceed 9.4 m³/hr to prevent media bypass

💡 Tip: The pump should provide sufficient flow for effective backwashing whilst not exceeding the filter’s maximum rated flow during normal filtration.

🔄 Maintenance Guide

Routine Maintenance Schedule

Task	Frequency	Procedure
Check pressure gauge	Weekly	Note baseline reading when filter is clean
Backwash	Every 1-2 weeks or when pressure rises 0.5-1 bar above baseline	Run until sight glass clears (typically 2-3 minutes)
Rinse after backwash	After each backwash	Run for 30-60 seconds to settle media
Inspect seals and O-rings	Seasonally	Replace if worn, cracked or compressed
Check media level	Annually	Top up if level has dropped significantly
Full media replacement	Sand: 5-7 years / Glass: 10+ years	Replace completely when filtration quality declines

Pressure Gauge Guide

• 📊 Clean filter baseline: Note this reading after a fresh backwash
• 📊 Backwash required: 0.5-1 bar above baseline
• 📊 Maximum safe operating pressure: 2.5 bar

Winterisation (UK Climate)

For outdoor installations in the UK, proper winterisation is essential:

1. Drain the filter tank completely via the drain plug
2. Remove and safely store the drain plug indoors
3. Set multiport valve to “Winterise” position (between settings) to prevent seal damage
4. Cover the filter or relocate to a frost-free location if possible
5. Never leave water in the filter tank during freezing conditions

🪨 Filter Media Information

This filter is supplied without media – allowing you to choose the filtration solution that best suits your needs and budget.

Compatible Media Types

Media Type	Filtration Rating	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, longer lasting, eco-friendly
Zeolite	3-5 microns	5 years	Superior clarity, removes ammonia
Glass Pearl	5-10 microns	10+ years	Premium filtration performance

Media Capacity for E500

Media Type	Quantity Required
Glass Pearl	100 kg
Crushed Glass (0.5-1mm)	83 kg
Silica Sand (16/30)	90 kg
Zeolite (1-2.2mm)	75 kg

💡 Tip: Glass media offers superior filtration (5-15 microns vs 20-40 microns for sand) and lasts significantly longer, making it an excellent long-term investment despite the higher initial cost.

Signs Media Needs Replacing

• Poor water clarity despite correct chemical balance
• Shortened filter cycles between backwashes
• Cloudy water returning to pool after filtration
• Visible channelling or clumping in media bed
• Filter not holding pressure properly

🛠️ Valve Positions & Functions

The 40mm multiport valve provides six operational positions:

Position	Function	When to Use
Filter	Normal filtration mode	Daily operation – water flows through media to pool
Backwash	Reverse flow to clean media	When pressure rises 0.5-1 bar above clean baseline
Rinse	Settle media after backwash	Always run for 30-60 seconds after backwashing
Waste	Bypass filter, drain to waste	Vacuuming heavy debris, lowering water level
Recirculate	Bypass filter, return to pool	Distributing chemicals, heating without filtering
Closed	Stop all flow through valve	Pump maintenance, equipment servicing

⚠️ Important: Always switch off the pump before changing valve positions to prevent damage to internal components.
