🛠️ Maintenance Guide

Routine Maintenance Schedule:

Task	Frequency	How
Check pressure gauge	Weekly	Normal reading: 0.5-1.0 bar (clean filter baseline)
Backwash filter	When pressure rises 0.5-0.7 bar above baseline	Typically every 1-2 weeks
Rinse after backwash	After each backwash	Run rinse cycle for 30-60 seconds
Inspect pump strainer basket	Weekly	Remove debris, clean as required
Check pump lid O-ring	Monthly	Lubricate with silicone grease
Inspect valve seals	Seasonally	Replace if worn or cracked
Check sand level	Annually	Top up if media has settled
Full sand replacement	Every 5-7 years	Replace with 90kg grade 16/33 sand

Pressure Gauge Guide:

📊 Clean Filter Baseline: 0.5-1.0 bar

📊 Backwash Required: When pressure rises 0.5-0.7 bar above baseline

📊 Maximum Safe Pressure: 2.5 bar

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

Winterisation (UK Climate):

Proper winter preparation protects your investment from frost damage:

• Drain filter tank completely via drain plug
• Remove and store drain plug indoors
• Set multiport valve to “Winterise” position between settings or remove for storage
• Drain pump housing and remove drain plugs
• Cover filter and pump or relocate to frost-free location
• Never leave water in filter or pump during freezing conditions

🪨 Filter Media Information

Compatible Media Types:

Media Type	Capacity	Filtration Rating	Typical Lifespan	Benefits
Silica Sand (16/33 grade)	90 kg	20-40 microns	5-7 years	Economical, proven performance
Filter Glass	~80 kg	5-15 microns	10+ years	Finer filtration, reduced backwashing
ZeoSand	~75 kg	3-5 microns	5 years	Superior water clarity

This Package Includes: 90 kg Grade 16/33 silica sand (pre-measured for optimal 250mm bed depth)

Signs Media Needs Replacing:

• Poor water clarity despite correct chemical balance
• Short filter cycles between backwashes
• Cloudy water returning to pool after filter cycle
• Channelling visible in filter bed
• Media more than 7 years old

Media Replacement Tips:

💡 When replacing sand, consider upgrading to glass media for finer filtration and longer service life

💡 Always use pool-grade filter media, never play sand or builder’s sand

💡 Maintain correct 250mm bed depth for optimal filtration performance

💎 Filtration Performance

Performance Metric	Value
Filter Area	0.20 m²
Bed Depth	250mm
Standard Sand Filtration	20-40 microns
With Glass Media	5-15 microns
Maximum Flow Rate	9.4 m³/h (157 lpm)
Filtration Velocity	48 m³/hr/m² (residential rating)

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, improved clarity
3-5 microns	Ultra-fine particles, bacteria, exceptional clarity

Performance Notes:

The Exotuf E500’s 250mm bed depth provides excellent depth filtration, trapping debris throughout the sand bed rather than just at the surface. This design extends filter cycles between backwashes whilst maintaining consistent water clarity. The hydraulically balanced lateral system ensures even water distribution for maximum media contact.

⚙️ Multiport Valve Positions & Functions

Position	Function	When to Use
Filter	Normal filtration mode	Daily operation – water passes through sand bed
Backwash	Reverse flow cleans media	When pressure gauge reads high – run until sight glass clears
Rinse	Settles media after backwash	Always run for 30-60 seconds after backwashing
Waste	Bypass filter to drain	Vacuuming heavy debris, lowering water level
Recirculate	Bypass filter to pool	Circulating chemicals, heating without filtering
Closed	Stops all water flow	Pump maintenance, valve servicing

⚠️ Important: Always stop the pump before changing valve positions to prevent damage to internal seals.

❓ Frequently Asked Questions

Q: What size pool will this filter handle?

A: This system is rated for pools up to 56,500 litres based on a 6-hour turnover. For optimal performance, we recommend pools between 25,000 and 55,000 litres. Larger pools up to approximately 75,000 litres can achieve acceptable 8-hour turnover.

Q: How often do I need to backwash?

A: Backwash when the pressure gauge reads approximately 0.5-0.7 bar above your clean filter baseline. This typically occurs every 1-2 weeks during the swimming season, though frequency varies based on pool usage and environmental debris.

Q: What filter media should I use?

A: This package includes 90 kg of grade 16/33 silica sand. When replacing media, you may use standard pool sand, or upgrade to glass media (~80 kg) for finer filtration down to 5-15 microns with longer service life.

Q: How long does the filter media last?

A: Silica sand typically lasts 5-7 years with proper care. Glass media can last 10+ years. Signs of worn media include reduced water clarity and shortened filter cycles.

Q: Is the pump suitable for salt chlorinated pools?

A: Yes, the Certikin Swimflo pump is manufactured from corrosion-resistant composite materials suitable for both standard chlorine and salt chlorinated pool systems.

Q: How does this compare to the 24″ model?

A: The 20″ E500 is ideal for pools up to 56,500 litres, whilst the 24″ E600 handles pools up to 81,000 litres. Choose based on your pool volume for optimal turnover rates.

Q: What pump maintenance is required?

A: Weekly strainer basket cleaning, monthly O-ring inspection and lubrication, and seasonal mechanical seal checks. The self-priming design minimises maintenance requirements.

Q: What warranty is included?

A: The Exotuf filter tank carries a 10-year warranty for residential installations. The multiport valve has a 2-year warranty, and the Swimflo pump includes a 2-year manufacturer warranty. Contact Parts4Tubs for full warranty terms.

Q: Can I install this myself?

A: Whilst DIY installation is possible for competent individuals, we recommend professional installation by a qualified pool technician to ensure optimal performance, safety compliance, and warranty validity.

Q: What electrical supply do I need?

A: The 0.75HP Swimflo pump requires a single-phase 220-240V supply. A dedicated RCD-protected circuit is recommended. All electrical work should be completed by a qualified electrician.
