📏 Pool Sizing Guide

Sizing Principle:

Your filter’s flow rate should turn over the entire pool volume within 6-8 hours for optimal water quality.

Formula:

Pool Capacity (litres) = Flow Rate (m³/h) × Turnover Time (hours) × 1000

This Filter’s Capacity:

📍 Flow Rate: 22 m³/h
📍 6-Hour Turnover: Suitable for pools up to 132,000 litres
📍 8-Hour Turnover: Suitable for pools up to 176,000 litres

Pool Size Compatibility:

Pool Type	Volume Range	Suitability
🏊 Large above-ground	40,000-60,000 L	Excellent – generous capacity margin
🏠 Medium in-ground	50,000-80,000 L	Ideal match with optimal turnover
🏠 Large in-ground	80,000-130,000 L	Well suited for 6-8 hour cycles
🏠 Very large in-ground	130,000-175,000 L	Suitable with 8-hour turnover
🏢 Small commercial	Up to 130,000 L	Good choice for light commercial use

💡 Tip: For best water quality, select a filter that can turn over your pool volume in 6 hours rather than 8, providing a comfortable safety margin.

🛠️ Installation Requirements

Plumbing Connections:

Requirement	Specification
Inlet Connection	2″ (50 mm)
Outlet Connection	2″ (50 mm)
Valve Position	Top Mount
Pipework	50 mm / 2″ compatible

Physical Installation:

Requirement	Details
Base	Solid, level concrete or paving slab required
Clearance Above	Minimum 500 mm for valve operation and lid removal
Clearance Around	Minimum 300 mm for maintenance access
Location	Sheltered, well-ventilated area preferred

Pump Compatibility:

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

• Recommended pump flow rate: 18-22 m³/h
• Maximum flow rate: Do not exceed 22 m³/h
• Pump must generate sufficient head pressure to overcome filter resistance
• Match pipe diameter to 2″ connections for optimal flow

🔄 Maintenance Guide

Routine Maintenance:

Task	Frequency	Procedure
Check pressure gauge	Weekly	Note baseline and monitor for increases
Backwash filter	When pressure rises 0.5-1.0 bar above baseline	Run until sight glass shows clear water
Rinse after backwash	After every backwash	Run for 30-60 seconds to settle media
Inspect seals and O-rings	Seasonally	Check for wear, replace if damaged
Check media level	Annually	Top up if level has dropped
Full media replacement	Every 5-7 years	Replace sand completely

Pressure Gauge Guide:

📊 Clean filter baseline: 0.5-1.0 bar (note your specific reading)
📊 Backwash required: When 0.5-1.0 bar above your baseline
📊 Maximum safe operating: 2.5 bar

⚠️ Warning: If pressure exceeds 2.5 bar, stop the pump immediately and investigate the cause.

Winterisation (UK Climate):

For pools that will not be used during winter months:

• Drain the filter tank completely using the drain plug
• Remove and safely store the drain plug to prevent water accumulation
• Consider covering the filter or relocating to a frost-free area
• Never leave standing water in the filter during freezing conditions
• Inspect all seals before recommissioning in spring

🪨 Filter Media Information

Compatible Media:

Media Type	Filtration Rating	Typical Lifespan	Key Benefits
Silica Sand (#16)	20-40 microns	5-7 years	Economical, proven performance
Glass Media	5-15 microns	10+ years	Finer filtration, eco-friendly
ZeoSand/Zeolite	3-5 microns	5 years	Superior clarity, ammonia removal

Media Requirements:

• Sand capacity: 175 kg
• Gravel base layer: 50 kg (required beneath sand)
• Total media weight: 225 kg

Signs Media Needs Replacing:

• Persistent cloudy water despite correct chemical balance
• Very short filter cycles between backwashes
• Sand or media particles visible in pool water
• Filter pressure remains high even after backwashing
• Media has become compacted or channelled

🔬 Filtration Performance

Metric	Value
Flow Rate	22 m³/h
Filtration Area	0.45 m²
Filtration Velocity	50 m³/h/m²
Filtration Rating (Sand)	20-40 microns
Filtration Rating (Glass)	5-15 microns

Micron Rating Guide:

Rating	What It Captures
40+ microns	Visible debris, leaves, large particles
20-40 microns	Sand, dirt, visible suspended particles
10-20 microns	Fine particles, some algae spores
5-10 microns	Very fine particles, most algae, superior clarity

💡 Upgrade Tip: For enhanced water clarity, consider using glass media instead of sand. Glass media can filter down to 5-15 microns and typically lasts twice as long as traditional sand.

⚙️ Valve Positions & Functions

The 6-way multiport valve provides complete control over your filtration system:

Position	Function	When to Use
Filter	Normal filtration mode	Daily operation – water passes through media and returns clean to pool
Backwash	Reverses flow to clean media	When pressure gauge rises 0.5-1.0 bar above baseline
Rinse	Settles media after backwash	Always use for 30-60 seconds after backwashing
Waste	Bypasses filter, drains to waste	Vacuuming heavy debris, lowering water level
Recirculate	Bypasses filter, returns to pool	Circulating chemicals without filtering
Closed	Stops all water flow	Pump maintenance, winterisation

⚠️ Important: Never operate the valve handle whilst the pump is running. Always switch off the pump before changing valve positions.

🎯 Ideal Applications

Application	Pool Volume	Suitability
🏊 Large above-ground pools	40,000-60,000 L	Excellent – provides generous filtration capacity
🏠 Medium residential in-ground	50,000-80,000 L	Ideal – well matched for typical family pools
🏠 Large residential in-ground	80,000-130,000 L	Very good – comfortable 6-8 hour turnover
🏠 Very large residential	130,000-175,000 L	Suitable – operates at higher end of range
🏢 Small commercial/holiday lets	Up to 130,000 L	Good – robust construction suits commercial environments

❓ Frequently Asked Questions

Q: What size pool will this filter handle?

A: The EHS760/T is suitable for pools up to approximately 175,000 litres with an 8-hour turnover, or 132,000 litres with a 6-hour turnover. For optimal water quality, we recommend sizing for 6-hour turnover where possible.

Q: How often do I need to backwash?

A: Backwash when the pressure gauge reads 0.5-1.0 bar above your clean baseline reading. This is typically every 1-2 weeks depending on pool usage and debris levels.

Q: What filter media should I use?

A: The filter is compatible with standard silica sand (175 kg), glass media, or zeolite. You’ll also need 50 kg of gravel for the base layer. Glass media offers finer filtration and longer lifespan.

Q: How long does the filter media last?

A: Silica sand typically lasts 5-7 years with proper maintenance. Glass media can last 10+ years. ZeoSand typically lasts around 5 years.

Q: What pump do I need?

A: Match with a pump delivering approximately 18-22 m³/h. The pump should not exceed the filter’s maximum flow rate of 22 m³/h. Ensure your pump has adequate head pressure for your system.

Q: What is the maximum working pressure?

A: The maximum working pressure is 2.5 bar. The filter has been tested to 4 bar (20,000 cycles). Recommended operating pressure is 0.5-1.6 bar.

Q: Can this filter be used with heated pools?

A: Yes, the EHS760/T is rated for a maximum operating temperature of 50°C, making it suitable for heated pool applications.

Q: What warranty is included?

A: Please contact Parts4Tubs for full warranty terms and conditions applicable to this product.

Q: What is the weight when filled with media?

A: Empty weight is 33 kg. With 175 kg sand and 50 kg gravel, total weight when filled is approximately 258 kg. Ensure your installation base can support this weight.
