🔄 Maintenance Guide

Routine Maintenance Schedule

Task	Frequency	Details
Check pressure gauge	Weekly	Record baseline reading when clean
Backwash filter	Every 1-2 weeks	When pressure rises 0.5-0.7 bar above baseline
Rinse after backwash	After each backwash	Run for 30-60 seconds until water clears
Inspect pump basket	Weekly	Remove debris, check for damage
Check pump lid seal	Monthly	Replace if worn or cracked
Inspect filter media level	Annually	Top up if low
Full media replacement	Every 5-7 years	Or when water clarity declines

Pressure Gauge Guide

📊 Clean filter baseline: 0.8 – 1.2 bar (typical)

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

📊 Maximum safe operating pressure: 2.5 bar

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

Backwashing Procedure

1. Turn off pump
2. Set multiport valve to BACKWASH position
3. Turn on pump and run until sight glass shows clear water (typically 3-5 minutes for 30″ filter)
4. Turn off pump
5. Set valve to RINSE position
6. Turn on pump for 45-60 seconds
7. Turn off pump
8. Return valve to FILTER position
9. Resume normal operation

💡 Note: The 30″ filter requires longer backwash cycles than smaller filters due to greater media volume. The Lacron fishbone lateral design is 15% more efficient on backwashing than standard star configurations, helping offset this.

Winterisation (UK Climate)

• Drain all water from pump, filter tank, and pipework completely
• Remove and store drain plugs safely
• Set multiport valve to WINTER position (between settings)
• Cover or store pump in frost-free location
• Never leave water in the system during freezing conditions—ice damage is not covered by warranty
• For commercial installations, follow site-specific winterisation procedures

🪨 Filter Media Information

Total Media Capacity: 200kg

Media Loading for 30″ Filter (Recommended Configuration)

Layer	Media Type	Quantity	Purpose
Bottom	Pea Gravel (3-5mm)	50kg	Even flow distribution, protects laterals
Top	Grade 16/30 Silica Sand	150kg	Primary filtration

⚠️ Important: The 30″ filter requires a pea gravel base layer for optimal performance. The gravel ensures even water distribution across the filter bed and reduces bacterial growth in dead zones below the laterals.

Alternative Media Options

Media Type	Sand Quantity	Gravel	Filtration Rating	Lifespan
Silica Sand + Gravel	150kg	50kg	20-40 microns	5-7 years
Glass Media + Gravel	120kg	50kg	5-15 microns	10+ years
Zeolite + Gravel	120kg	50kg	3-5 microns	5 years

Media Loading Procedure

1. Fill filter 1/3 full with water before adding media (protects laterals)
2. Add pea gravel first, ensuring level layer just covering laterals
3. Add sand carefully on top of gravel layer
4. Do not overfill—media should be approximately 2/3 of tank depth

Signs Media Needs Replacing

• Poor water clarity despite correct chemical balance
• Short filter cycles between backwashes
• Channelling visible through clear lid
• Media visible in pool returns
• Filter more than 7 years old (sand) or 10 years (glass)

🛠️ Multiport Valve Positions & Functions

Position	Function
FILTER	Normal filtration—water flows through media and returns to pool
BACKWASH	Reverse flow to clean media—dirty water exits via waste line
RINSE	Settles media after backwash—run for 45-60 seconds
WASTE	Bypasses filter—water drains directly to waste (for lowering water level)
RECIRCULATE	Bypasses filter—water returns to pool without filtration
CLOSED	Stops all water flow—use only when pump is off
WINTER	Between positions—relieves pressure on spider gasket for storage

⚠️ Important: Never turn multiport valve handle while pump is running—this can damage the spider gasket.

❓ Frequently Asked Questions

Q: What size pool will this filter and pump combination handle? A: This combination is suitable for pools up to 108,000 litres with optimal 6-hour turnover, or up to 130,000 litres with 8-hour turnover. The filter’s design flow rate is 22.5 m³/h, with the pump delivering 18 m³/h.

Q: How does the 30″ compare to the 24″ model? A: The 30″ offers significantly more capacity: 22.5 m³/h vs 14.5 m³/h flow rate, 0.46 m² vs 0.20 m² filter area (130% more), 200kg vs 125kg media capacity, and 2″ vs 1.5″ valve connections. It’s designed for pools 80,000L and above.

Q: Why does the 30″ filter need pea gravel? A: Pea gravel creates an even flow distribution layer at the bottom of larger filters. Without it, “dead zones” can develop below the laterals where water doesn’t circulate properly, potentially leading to bacterial growth and reduced backwash effectiveness.

Q: How often do I need to backwash the filter? A: Backwash when the pressure gauge reads 0.5-0.7 bar above the clean baseline reading. Due to the larger filter area, this typically occurs every 1-2 weeks depending on pool usage and debris levels.

Q: Is this combination suitable for commercial pools? A: This is rated for light commercial applications up to 130,000 litres. For full commercial use, verify compliance with local health and safety regulations—some jurisdictions require higher turnover rates or additional filtration for public pools.

Q: What filter media should I use? A: Load 50kg pea gravel first (covering laterals), then 150kg Grade 16/30 silica sand on top. For finer filtration, glass media (120kg) can replace sand while keeping the gravel base.

Q: How long does filter media last? A: Silica sand typically lasts 5-7 years, glass media 10+ years, and zeolite approximately 5 years. Replace when water clarity diminishes despite correct chemical balance.

Q: Is this combination suitable for saltwater pools? A: Yes, both the Lacron filter and Aquaspeed pump are fully compatible with salt chlorinated pool systems.

Q: What warranty is included? A: The filter tank carries a 5-year warranty with 1-year warranty on components. The pump has a 2-year warranty with 1 year on mechanical seal and capacitor. Contact Parts4Tubs for full warranty terms.

Q: Is the 1.5HP pump adequate for this filter size? A: Yes, the 1.5HP Aquaspeed delivers 18 m³/h which is well-matched to the filter. The pump is designed to work within the filter’s optimal flow range without exceeding it, ensuring efficient filtration and extended media life.
