📐 Pool Sizing Guide

Sizing Principle:

The filter flow rate should turn over the entire pool volume in 6-8 hours for optimal water quality.

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 – Ideal match
🏠 Large Above-Ground	40,000-60,000 L	✅ Very Good – Recommended
🏊 Small In-Ground	Up to 50,000 L	✅ Excellent – Perfect sizing
🏊 Medium In-Ground	50,000-80,000 L	✅ Good – Suitable with 8hr turnover
🏢 Small Commercial	Up to 60,000 L	✅ Good – Entry-level commercial

This Filter:

📍 Flow Rate: 10m³/hr (10,000 litres per hour)

📍 Suitable for pools up to: 60,000-80,000 litres (with 6-8 hour turnover)

📍 Example calculation: A 60,000L pool ÷ 10m³/hr = 6 hours turnover time ✅

🔌 Installation Requirements

Plumbing Connections:

Requirement	Specification
Inlet Connection	1.5″ (38mm)
Outlet Connection	1.5″ (38mm)
Valve Position	Side Mount
Connection Type	Threaded

Physical Installation:

Requirement	Details
Base	Solid, level, horizontal surface required
Location	As close to pool as practical
Ideal Position	0.5m below pool water level (if possible)
Drainage	Install near a suitable drain point
Clearance	Allow adequate space around filter for maintenance

Pump Compatibility:

⚠️ Important: Filter must be matched with an appropriate pump for optimal performance.

• Recommended pump flow rate: 8-10m³/hr
• Minimum pump flow rate: 6m³/hr
• Maximum pump flow rate: Do not exceed 10m³/hr
• Typical pump size: 0.5HP to 0.75HP

💡 Tip: Use plastic fittings and PTFE tape for all connections. Never use iron pipe fittings or hemp for the valve connections.

🔄 Maintenance Guide

Routine Maintenance Schedule:

Task	Frequency	Method
Check pressure gauge	Weekly	Record baseline reading
Backwash	When pressure rises 0.5 bar above baseline	Run until sight glass clears
Rinse after backwash	After each backwash	30-60 seconds
Inspect seals and gaskets	Seasonally	Replace if worn or damaged
Check sand level	Annually	Top up if low
Full sand replacement	Every 3-5 years	Replace completely
Chemical sand cleaning	Annually	Use filter cleaner product

Pressure Gauge Guide:

📊 Clean filter baseline: 0.8 kg/cm² (11.4 PSI)

📊 Backwash required: 1.3 kg/cm² (18.5 PSI)

📊 Maximum safe pressure: 2.0 kg/cm² (28.4 PSI)

Valve Positions:

• Filter – Normal filtration operation
• Backwash – Reverse flow to clean sand media
• Rinse – Settle sand after backwash (run 1 minute)
• Waste – Bypass filter, drain water to waste
• Recirculate – Bypass filter, return water to pool
• Closed – Stop all water flow

⚠️ Critical: Always switch off the pump before changing valve positions.

Winterisation (UK Climate):

• Perform a backwash and rinse cycle
• Drain filter tank completely via drain valve
• Remove filter lid to allow ventilation during storage
• Store drain plug safely
• Cover filter or store in frost-free location if possible
• Never leave water in filter during freezing conditions

🪨 Filter Media Information

Compatible Media Types:

Media Type	Filtration Rating	Lifespan	Benefits
Silica Sand (16/30 grade)	20-40 microns	3-5 years	Economical, proven performance
Glass Media	5-15 microns	10+ years	Finer filtration, uses 20% less
ZeoSand	3-5 microns	5 years	Superior water clarity

Media Capacity: Approximately 75kg of 0.5-0.7mm silica sand

Sand Loading Instructions:

1. Position filter in final location with pipework connected
2. Remove lid and gasket
3. Fill filter halfway with water (protects laterals during loading)
4. Pour required quantity of sand into filter
5. Clean gasket seating area
6. Replace gasket and secure lid

Signs Media Needs Replacing:

• Poor water clarity despite correct chemical balance
• Short filter cycles between backwashes
• Sand or debris returning to pool
• Pressure gauge not returning to baseline after backwash
• Channelling visible in sand bed

❓ Frequently Asked Questions

Q: What size pool will this filter handle?

A: The ZZFBS500 is suitable for pools up to 60,000-80,000 litres. With its 10m³/hr flow rate, it will turn over a 60,000 litre pool in 6 hours, or an 80,000 litre pool in 8 hours.

Q: How often do I need to backwash?

A: Backwash when the pressure gauge reads approximately 0.5 bar (7 PSI) above your clean baseline reading, typically every 1-2 weeks during the swimming season depending on pool usage and debris levels.

Q: What filter media should I use?

A: The filter is designed for 0.5-0.7mm (16/30 grade) silica sand, requiring approximately 75kg. You can alternatively use glass media (use 20% less by weight) or ZeoSand for improved filtration performance.

Q: How long does the filter media last?

A: Silica sand typically lasts 3-5 years with proper maintenance. Glass media can last 10+ years. Annual cleaning with a filter cleaner product helps extend media life.

Q: What pump do I need with this filter?

A: Match with a pump delivering 8-10m³/hr for optimal performance. A 0.5HP to 0.75HP pump is typically suitable. Never exceed the filter’s maximum flow rate of 10m³/hr.

Q: Is the valve included?

A: Yes, the ZZFBS500 comes complete with a 6-way side mount multiport valve, pressure gauge, and drain valve ready for installation.

Q: What is the working pressure limit?

A: The maximum working pressure is 2 kg/cm² (28.4 PSI). Normal operating pressure should be around 0.8-1.3 kg/cm².

Q: Can I use this filter with a salt chlorinator?

A: Yes, the HDPE construction is resistant to the slightly higher salt levels found in salt-chlorinated pools.
