🧹 Maintenance Guide
Routine Maintenance Schedule
| Task | Frequency | Details |
|---|---|---|
| Check pressure gauge | Weekly | Record baseline and monitor increase |
| Inspect pump strainer basket | Weekly | Clean debris, check for damage |
| Backwash filter | When required | When pressure rises 0.5-1.0 bar above baseline |

Pressure Gauge Guide
📊 Clean Filter Baseline: 0.5-1.0 bar (typical)
📊 Backwash Required: 0.5-1.0 bar above baseline
📊 Maximum Safe Operating Pressure: 2.5 bar
Visual Monitoring Advantage
💡 Top Mount Benefit: The clear valve mounting ring allows you to visually confirm:
- Water clarity during filtration
- Debris removal during backwashing
- When backwash cycle is complete (water runs clear)
- Proper rinse cycle operation
Backwash Procedure
- Turn off pump – Always switch off before adjusting valve
- Set valve to BACKWASH – Rotate multiport valve handle
- Turn on pump – Watch through clear ring until water runs clear (2-3 minutes typical)
- Turn off pump – Switch off before changing valve position
- Set valve to RINSE – Settle the filter media
- Turn on pump – Run for 30-60 seconds
- Turn off pump – Switch off before returning to filter mode
- Set valve to FILTER – Return to normal operation
- Turn on pump – Resume normal filtration
Winterisation (UK Climate)
❄️ Essential Steps for Frost Protection:
- Switch off pump and isolate electrical supply
- Set multiport valve to WINTERISE or CLOSED position
- Remove drain plug from filter tank base
- Drain all water from filter tank completely
- Remove pump lid and drain pump housing
- Remove drain plugs from pump (if fitted)
- Store all drain plugs safely for spring
- Cover filter and pump or relocate to frost-free storage
- Disconnect and drain all pipework where possible
⚠️ Never leave water in filter or pump during freezing conditions – ice expansion can crack tanks and housings.

❓ Frequently Asked Questions
Q: What size pool will this package handle?
A: This complete system is suitable for pools up to 72,000 litres with an 8-hour turnover, or up to 54,000 litres for a 6-hour turnover. This covers most residential above-ground and smaller in-ground swimming pools.
Q: What’s the advantage of top mount over side mount?
A: The top mount configuration features a unique clear valve mounting ring that allows you to visually monitor water clarity during filtration and see when backwashing is complete. The compact design also offers a smaller footprint, ideal for tight plant room spaces.
Q: Is this package suitable for saltwater pools?
A: Yes, both the Vision filter and Aquaspeed pump are fully compatible with salt chlorination systems. The pump features a 316 stainless steel mechanical seal specifically for salt pool applications.
Q: How often do I need to backwash the filter?
A: Backwash when the pressure gauge reads 0.5-1.0 bar above your clean filter baseline reading, or when you notice reduced water clarity through the clear valve ring. In typical domestic use, this is usually every 1-2 weeks during the swimming season.
Q: What filter media is included?
A: This package includes 90 kg of filter grade silica sand. The filter is also compatible with glass media and ZeoSand alternatives if you prefer finer filtration.
Q: How long does the filter sand last?
A: Filter sand typically lasts 5-7 years before requiring replacement. Glass media can last 10+ years and provides finer filtration.
Q: Can I replace the sand with glass media?
A: Yes, the Vision filter is fully compatible with glass filter media. Glass requires approximately 30% less by weight (around 63 kg), offers finer 5-15 micron filtration, and lasts significantly longer than sand.
Q: What warranty is included?
A: The Vision filter tank carries an impressive 10-year warranty for residential installations. The Aquaspeed pump has a 2-year limited warranty (1 year on mechanical seal and capacitor).
Q: Is this compatible with my existing pipework?
A: The system uses standard 1.5″/50mm connections with quick connect unions included. The pump comes with 2″ connections and 1.5″ reducers are supplied for the 0.75HP model, offering flexibility for most domestic installations.
Q: Can I use this filter with Baquacil?
A: No, Vision filters are NOT suitable for use with Baquacil products. Use only with chlorine, salt chlorination, or bromine sanitisation systems.
Q: What electrical supply do I need?
A: The 0.75HP Aquaspeed pump requires a 220-240V single phase supply. It comes with approximately 1.5 metres of pre-wired cable. All electrical installation must be carried out by a qualified electrician.
Q: How does the clear valve ring help with maintenance?
A: The transparent mounting ring allows you to see water flow during operation. During backwashing, you can watch the water change from dirty to clear, confirming when the cycle is complete. This visual feedback helps you maintain optimal filter performance.
