📐 Pool Sizing Guide

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

Formula:

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

Pool Size Compatibility

Pool Type	Volume Range	Suitability
🏊 Medium above-ground	20,000-40,000 L	✅ Excellent – optimal performance
🏊 Large above-ground	40,000-60,000 L	✅ Very good – efficient turnover
🏠 Small in-ground	Up to 50,000 L	✅ Excellent – ideal match
🏠 Medium in-ground	50,000-72,000 L	✅ Good – 8-hour turnover
🏠 Large in-ground	72,000+ L	⚠️ Consider larger model

🛠️ Installation Requirements

Plumbing Connections

Requirement	Specification
Inlet Connection	1½” (38mm)
Outlet Connection	1½” (38mm)
Valve Position	Top mount
Connection Type	Female thread

Physical Installation

Requirement	Details
Base	Solid, level concrete pad or paving required
Clearance Above	Minimum 500mm for valve operation and media loading
Clearance Around	Minimum 300mm for maintenance access
Location	Sheltered position recommended; protect from direct weather

Pump Compatibility

⚠️ Important: The filter must be correctly matched with an appropriate pump for optimal performance.

Parameter	Recommendation
Recommended Pump Flow Rate	6-9 m³/h
Maximum Pump Flow Rate	Do not exceed 15 m³/h
Pump Position	Before filter (pressure side)

💡 Tip: Oversizing your pump can reduce filtration efficiency and increase wear. Match your pump output to the filter’s normal flow rate of 9 m³/h for best results.

🔄 Maintenance Guide

Routine Maintenance Schedule

Task	Frequency	Method
Check pressure gauge	Weekly	Note baseline and current reading
Backwash filter	When pressure rises 0.5-0.7 bar above baseline	Run until sight glass clears (2-3 minutes)
Rinse after backwash	After each backwash	30-60 seconds on Rinse position
Inspect valve seals	Seasonally	Check for leaks; replace if worn
Check media level	Annually	Top up if level has dropped
Full media replacement	Every 5-7 years (sand)	Complete media change

Pressure Gauge Guide

📊 Clean filter baseline: 0.8-1.0 bar (typical)
📊 Backwash required: When pressure rises 0.5-0.7 bar above baseline
📊 Maximum operating pressure: 2.5 bar

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

Winterisation for UK Climate

Proper winter preparation is essential to protect your filter from frost damage:

1. Switch off and disconnect the pump from electrical supply
2. Set multiport valve to Winterise or between two positions
3. Drain the filter tank completely using the drain plug at the base
4. Remove and store the drain plug in a safe place
5. Leave the air release valve open to prevent pressure build-up
6. Cover the filter or move to a frost-free location if possible
7. Never leave water in the filter during freezing conditions – ice expansion can crack the tank

💡 Tip: Performing a final backwash before winterisation helps remove accumulated debris and keeps the media in good condition over winter.

🪨 Filter Media Information

Compatible Media Types

Media Type	Filtration Rating	Lifespan	Benefits
Silica Sand	20-40 microns	5-7 years	Economical, proven performance
Glass Media	5-15 microns	10+ years	Finer filtration, longer lasting
ZeoSand	3-5 microns	5 years	Superior water clarity, ammonia removal

Media Capacity

Media	Quantity Required
Sand (Grade 16/30)	150 kg
Support Gravel	120 kg
Total Media	270 kg

Loading Order

1. Ensure laterals and stand pipe are correctly positioned
2. Add support gravel layer first (120 kg)
3. Add sand or glass media on top (150 kg)
4. Use the folding diffuser for easy access
5. Fill tank with water before first backwash

Signs Media Needs Replacing

• Poor water clarity despite correct chemical balance
• Shortened filter cycles requiring frequent backwashing
• Cloudy water returning to pool after filtration
• Visible channelling or clumping in media bed
• Filter media escaping into pool

🔬 Filtration Performance

Metric	Value
Filtration Rating	20-40 microns (with sand)
Filter Area	0.3 m²
Media Bed Depth	Approximately 500mm

Micron Rating Guide

Rating	What It Removes
40+ microns	Large visible debris, leaves, insects
20-40 microns	Sand, dirt, visible particles, hair
10-20 microns	Fine particles, some algae spores
5-10 microns	Very fine particles, most algae, pollen
Under 5 microns	Bacteria, finest particles (requires DE or enhanced media)

💡 Upgrade Tip: Switching from sand to glass media can improve filtration from 20-40 microns down to 5-15 microns, delivering noticeably clearer water with fewer chemicals required.

⚙️ Valve Positions & Functions

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

Position	Function	When to Use
Filter	Normal filtration – water flows through media and returns clean to pool	Daily operation
Backwash	Reverses flow to flush debris from media to waste	When pressure rises 0.5-0.7 bar above baseline
Rinse	Settles media and clears residual debris to waste	30-60 seconds after each backwash
Waste	Bypasses filter, sends water directly to drain	Vacuuming heavy debris, lowering water level
Recirculate	Bypasses filter, returns water directly to pool	Distributing chemicals, troubleshooting
Closed	Stops all water flow through valve	Pump maintenance, winterisation

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

❓ Frequently Asked Questions

Q: What size pool will this filter handle?
A: The PPG Filter Top 620 V6 is suitable for pools up to 72,000 litres with an 8-hour turnover cycle, or up to 54,000 litres for optimal 6-hour turnover. This covers most medium to large residential swimming pools.

Q: How often do I need to backwash?
A: Backwash when the pressure gauge reads 0.5-0.7 bar above the clean baseline reading. This is typically every 1-2 weeks during the swimming season, though frequency varies based on pool usage and debris load.

Q: What filter media should I use?
A: The filter is compatible with silica sand (Grade 16/30), glass media, or ZeoSand. Sand capacity is 150 kg with 120 kg of support gravel. Glass media offers finer filtration down to 5-15 microns.

Q: How long does filter media last?
A: Sand media typically lasts 5-7 years before replacement is needed. Glass media can last 10+ years. Signs of worn media include poor water clarity and shortened filter cycles.

Q: What pump do I need?
A: Match your pump to deliver 6-9 m³/h for optimal performance. The pump flow rate should not exceed 15 m³/h (the filter’s maximum backwash capacity). Most 0.5-0.75 HP pool pumps are suitable.

Q: What warranty is included?
A: The filter comes with a 5-year manufacturer’s warranty on the tank. Contact Parts4Tubs for full warranty terms and conditions.

Q: Can I use this filter with salt water pools?
A: Yes, the polyester-reinforced tank and internal components are resistant to salt water corrosion. Ensure all external plumbing connections are also salt-compatible.

Q: How do I know when to replace the sand?
A: Replace sand when you notice consistently poor water clarity despite correct chemical balance, very short filter cycles, or sand particles appearing in the pool. This typically occurs after 5-7 years of use.

Q: What is the difference between this and the Side Mount version?
A: Top mount filters like this model have the multiport valve on top of the tank, making them more compact and ideal where horizontal space is limited. Side mount filters have the valve on the side, which some find easier to access.

Q: Can this filter be automated?
A: Yes, the Praher valve is compatible with the AquaStar automatic backwash system for hands-free operation. Contact Parts4Tubs for compatible automation accessories.
