📍 Pool Sizing Guide

Sizing Principle: For optimal water quality, your filter should turn over the entire pool volume every 6-8 hours during swimming season.

Formula:

Required Flow Rate (m³/h) = Pool Volume (m³) ÷ Turnover Time (hours)

Pool Size Compatibility:

Pool Type	Volume Range	CC75 Suitability
🏊 Small above-ground	Up to 30,000 L	✅ Excellent – generous headroom
🏊 Medium above-ground	30,000 – 60,000 L	✅ Excellent – ideal match
🏊 Large above-ground	60,000 – 80,000 L	✅ Very Good – comfortable capacity
🏠 Small in-ground	Up to 50,000 L	✅ Excellent – plenty of margin
🏠 Medium in-ground	50,000 – 80,000 L	✅ Very Good – well suited
🏠 Larger in-ground	80,000 – 100,800 L	✅ Good – at maximum capacity

This Filter:

📍 Flow Rate: 16.8 m³/h (280 litres per minute)

📍 Suitable for pools up to: 100,800 litres

📍 Optimal for pools: 40,000 – 80,000 litres (6-hour turnover)

Example Calculations:

• 50,000 L pool ÷ 16.8 m³/h = 3-hour turnover ✅ Excellent
• 70,000 L pool ÷ 16.8 m³/h = 4.2-hour turnover ✅ Very Good
• 100,800 L pool ÷ 16.8 m³/h = 6-hour turnover ✅ Good

⚙️ Installation Requirements

Plumbing Connections:

Requirement	Specification
Inlet Connection	50 mm (1½”)
Outlet Connection	50 mm (1½”)
Union Type	Quick connect (metric and imperial supplied)
Valve Position	Top-mounted lid

Physical Installation:

Requirement	Details
Base	Solid, level concrete or paving slab
Clearance Above	550 mm minimum for lid removal
Clearance Around	350 mm for cartridge access and maintenance
Location	Frost-free area or protected enclosure recommended

Pump Compatibility:

⚠️ Important: The filter must be correctly matched with an appropriate pump for optimal performance.

Parameter	Recommendation
Recommended Pump Flow	12 – 16 m³/h
Maximum Pump Flow	16.8 m³/h
Minimum Pump Flow	8 m³/h (for adequate filtration)

💡 Tip: The CC75 pairs well with most 0.5 to 0.75 HP single-speed pumps or variable-speed pumps. Ensure your pump output does not exceed the filter’s maximum flow rate of 16.8 m³/h.

Installation Notes:

• Position filter on a flat, level surface
• Secure the filter base to prevent movement during operation
• Use recommended solvent cement for all permanent pipe connections
• Allow 24 hours for adhesive to cure before operation
• Hand-tighten the pressure gauge only – do not overtighten

🛠️ Maintenance Guide

Routine Maintenance Schedule:

Task	Frequency	Procedure
Check pressure gauge	Weekly	Note reading; baseline typically 60-100 kPa
Clean cartridge	When pressure rises 50 kPa above baseline	Hose down pleats thoroughly
Deep clean cartridge	Monthly or as needed	Soak in cartridge cleaning solution overnight
Inspect O-rings and seals	Seasonally	Replace if cracked or worn
Check air bleed operation	Monthly	Ensure air releases properly at start-up
Full cartridge replacement	Every 1-3 years	Depending on usage and water conditions

Pressure Gauge Guide:

📊 Clean filter baseline: Typically 60-100 kPa (varies by installation)

📊 Cleaning required: When pressure rises 50 kPa above your baseline

📊 Example: If baseline is 75 kPa, clean when gauge reads 125 kPa

📊 Maximum safe pressure: 350 kPa (3.5 bar)

Cartridge Cleaning Procedure:

1. Turn off the pump and close isolation valves
2. Release pressure via air bleed valve
3. Turn the hand-operated lid lock ring anti-clockwise to unlock
4. Remove the lid and lift out the cartridge
5. Hose the cartridge thoroughly inside and out with a garden hose
6. Clean between all pleats – use a dedicated cartridge cleaning wand for best results
7. For stubborn debris, soak overnight in Waterco cartridge cleaning solution
8. Inspect cartridge for damage; replace if torn or worn
9. Reinstall cartridge (self-centring mount ensures correct positioning)
10. Replace lid and secure lock ring
11. Open valves and restart pump
12. Use air bleed to purge trapped air until steady water stream emerges

⚠️ Important: Do not stand over the lid when opening the air bleed valve. Never exceed 12 months between cartridge cleaning intervals.

Winterisation (UK Climate):

For pools not operated during winter months:

• Run the filter on its final clean cycle
• Turn off pump and isolate the system
• Remove the cartridge and clean thoroughly
• Store the cartridge indoors in a dry location
• Drain all water from the filter tank
• Leave the lid slightly loose to prevent vacuum seal
• Consider covering the unit or relocating to a frost-free area
• Never leave standing water in the filter during freezing conditions

💎 Filtration Performance

Metric	Value
Filtration Rating	Approximately 30 microns (standard cartridge)
Filter Area	6.9 m² (75 ft²)
Flow Rate	16.8 m³/h

Micron Rating Comparison:

Rating	What It Captures
100+ microns	Large visible debris only
40-100 microns	Sand, hair, visible particles
20-40 microns	Fine particles, some algae spores
10-20 microns	Very fine particles, most algae
5-10 microns	Extremely fine particles, bacteria clumps

The CC75 Advantage:

The Trimline CC75’s 30-micron filtration captures particles finer than a human hair, effectively removing dirt, debris, skin cells, sunscreen residue, and algae spores. The substantial 6.9 m² pleated surface area provides excellent dirt-holding capacity, meaning longer intervals between cleaning compared to smaller filters.

As the middle model in the Trimline range, the CC75 offers the best balance between filtration capacity and physical size. It provides 50% more filter area than the CC50 whilst remaining compact enough for most residential equipment spaces – the ideal choice for typical UK garden pools.

Q: How often do I need to clean the cartridge?

A: Clean the cartridge when the pressure gauge reads approximately 50 kPa above its normal operating baseline – typically every 1-4 weeks depending on pool usage, bather load, and environmental factors. Heavy use periods may require more frequent cleaning.

Q: How do I clean the cartridge?

A: Remove the cartridge from the filter housing and hose it down thoroughly with a garden hose, paying particular attention to cleaning between all the pleats. For stubborn dirt or oils, soak the cartridge overnight in a dedicated cartridge cleaning solution.

Q: How long does the cartridge last?

A: With proper care and regular cleaning, a quality cartridge typically lasts 1-3 years. Factors affecting lifespan include frequency of use, water chemistry, bather load, and environmental debris. Genuine Waterco replacement cartridges (part 1597273075) are available, along with quality aftermarket alternatives.

Q: What pump do I need?

A: Match the CC75 with a pump delivering between 12 and 16.8 m³/h. Most 0.5 to 0.75 HP pumps are suitable. The pump flow rate should not exceed the filter’s maximum of 16.8 m³/h.

Q: Does this filter require backwashing?

A: No. The Trimline CC75 is a cartridge filter that does not require backwashing. Simply remove and hose clean the cartridge when the pressure gauge indicates cleaning is needed. This makes it ideal for locations with water restrictions or limited drainage.
