📐 Pool Sizing Guide

Sizing Principle: The filter flow rate should turn over the entire pool volume within 6-8 hours for optimal water quality. The Brasil ZZFBS400 delivers a flow rate of 6 m³/h, making it suitable for pools up to 48,000 litres.

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 – generous capacity
🏠 Medium above-ground	20,000-40,000 L	Ideal fit
🏊 Large above-ground	40,000-48,000 L	Suitable with 8-hour turnover
🏠 Small in-ground	Up to 30,000 L	Excellent performance
🏠 Medium in-ground	30,000-48,000 L	Good performance

This Filter:

• 📍 Flow Rate: 6 m³/h
• 📍 Suitable for pools up to: 48,000 litres
• 📍 Optimal for pools: 20,000-40,000 litres

🔌 Installation Requirements

Plumbing:

Requirement	Specification
Inlet Connection	1.5″ (38mm)
Outlet Connection	1.5″ (38mm)
Valve Position	Side mount

Physical Installation:

Requirement	Details
Base	Solid, level surface required
Clearance above	Minimum 300mm for lid removal
Clearance around	500mm minimum for maintenance access
Installation level	Ideally 0.5m below pool water level

Pump Compatibility:

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

• Recommended pump flow rate: 4 – 6 m³/h
• Pump must not exceed filter’s maximum flow rate of 6 m³/h
• Ensure pump provides adequate pressure for backwashing

💡 Installation Tip: Use PTFE tape and plastic fittings only. Do not use iron pipes or hemp for connections to the multiport valve.

🔄 Maintenance Guide

Routine Maintenance:

Task	When	How
Check pressure gauge	Weekly	Normal: 0.8-1.0 bar
Backwash	When pressure rises 0.5 bar above baseline	Run for 2 minutes until sight glass clears
Rinse after backwash	After each backwash	Run for 1 minute
Inspect seals	Start and end of season	Replace if worn or damaged
Check media level	Annually	Top up if below recommended level
Full media change	Every 3-5 years	Replace completely

Pressure Gauge Guide:

• 📊 Clean filter: 0.8 bar (baseline)
• 📊 Backwash needed: 1.3 bar (0.5 bar above baseline)
• 📊 Maximum safe: 2.0 bar

Winterisation (UK Climate):

1. Perform a final backwash and rinse cycle
2. Turn off pump and close all valves
3. Open drain valve and remove drain plug to empty tank completely
4. Remove filter lid to allow air circulation
5. Store in frost-free location if possible
6. Never leave water in filter during freezing conditions

⚠️ Important: Water left in the filter tank can freeze and cause irreparable damage to the vessel.

🪨 Filter Media Information

Compatible Media:

Media Type	Filtration	Lifespan	Benefits
Silica Sand (0.5-0.7mm)	20-40 microns	3-5 years	Economical, widely available
Glass Media	5-15 microns	10+ years	Finer filtration, lighter weight
ZeoSand	3-5 microns	5 years	Superior water clarity

Media Capacity: Approximately 35 kg

Media Loading Instructions:

1. Position filter in final location with plumbing connected
2. Remove lid and internal diffuser if fitted
3. Fill filter with water to approximately half capacity
4. Slowly pour in required quantity of sand or glass media
5. Clean lid seal seat thoroughly
6. Replace lid and tighten securely

Signs Media Needs Replacing:

• Poor water clarity despite correct chemical balance
• Short filter cycles between backwashes
• Cloudy water returning to pool after backwash
• Sand or media passing through to pool

🔬 Filtration Performance

Metric	Value
Filtration Rating (Sand)	20-40 microns
Filtration Rating (Glass)	5-15 microns
Filter Area	0.12 m²
Filtration Velocity	50 m³/h/m²

Micron Rating Guide:

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

💡 Upgrade Tip: Consider using recycled glass filter media (RGFM) instead of sand. Glass media provides finer filtration (5-15 microns vs 20-40 microns), requires approximately 15% less media by weight, and lasts significantly longer than traditional sand.

⚙️ Valve Positions & Functions

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

Position	Function
Filter	Normal filtration – water passes through media and returns to pool
Backwash	Reverses flow to flush dirt from media to waste drain
Rinse	Settles media after backwash, directs water to waste
Waste	Bypasses filter, sends water directly to waste drain
Recirculate	Bypasses filter media, returns water directly to pool
Closed	Stops all flow through valve – use when opening pump strainer

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

🎯 Ideal Applications

Application	Pool Size	Suitability
🏠 Residential above-ground pools	Up to 48,000 L	Excellent
🏠 Residential in-ground pools	Up to 40,000 L	Very good
🏡 Garden plunge pools	Up to 20,000 L	Excellent – over-specified
🏊 Swim spas	Up to 15,000 L	Good with appropriate pump

Particularly Suited For:

• First-time pool owners seeking reliable, easy-to-maintain filtration
• Above-ground pool installations where space is limited
• Replacement of ageing or undersized filters
• Budget-conscious installations requiring quality performance

❓ Frequently Asked Questions

Q: What size pool will this filter handle? A: The Brasil ZZFBS400 is suitable for pools up to 48,000 litres when operating with an 8-hour turnover cycle. For optimal performance, we recommend pools between 20,000 and 40,000 litres.

Q: How often do I need to backwash? A: Backwash when the pressure gauge reads approximately 1.3 bar (0.5 bar above your clean filter baseline). This typically occurs every 1-2 weeks during swimming season, depending on pool usage and debris load.

Q: What filter media should I use? A: The filter is compatible with silica sand (0.5-0.7mm grade), glass filter media, or ZeoSand. Media capacity is approximately 35 kg. We recommend glass media for superior filtration and longer service life.

Q: How long does filter media last? A: Silica sand typically requires replacement every 3-5 years. Glass filter media can last 10 years or more with proper maintenance.

Q: What pump do I need? A: Match with a pump delivering 4-6 m³/h. The pump flow rate must not exceed the filter’s maximum rating of 6 m³/h. Ensure the pump provides adequate pressure for effective backwashing.

Q: Can I use this filter with a heat pump or heater? A: Yes, the HDPE construction and 2 bar pressure rating make it suitable for use with pool heating systems. Maximum operating temperature is 40°C.

Q: Is this filter suitable for saltwater pools? A: Yes, the HDPE construction is resistant to the corrosive effects of saltwater chlorination systems.
