📐 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	CC50 Suitability
🏊 Small above-ground	Up to 20,000 L	✅ Excellent – generous headroom
🏊 Medium above-ground	20,000 – 40,000 L	✅ Excellent – ideal match
🏊 Large above-ground	40,000 – 55,000 L	✅ Very Good – comfortable capacity
🧖 Hot tubs and spas	Up to 3,000 L	✅ Excellent – more than adequate
🏡 Plunge pools	Up to 15,000 L	✅ Excellent – perfect fit
🏠 Small in-ground	Up to 68,400 L	✅ Good – at maximum capacity

This Filter:

📍 Flow Rate: 11.4 m³/h (190 litres per minute)

📍 Suitable for pools up to: 68,400 litres

📍 Optimal for pools: 25,000 – 55,000 litres (6-hour turnover)

Example Calculations:

• 30,000 L pool ÷ 11.4 m³/h = 2.6-hour turnover ✅ Excellent
• 45,000 L pool ÷ 11.4 m³/h = 3.9-hour turnover ✅ Very Good
• 68,400 L pool ÷ 11.4 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	500 mm minimum for lid removal
Clearance Around	300 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	8 – 11 m³/h
Maximum Pump Flow	11.4 m³/h
Minimum Pump Flow	5 m³/h (for adequate filtration)

💡 Tip: The CC50’s compact size makes it ideal for smaller single-speed or variable-speed pumps. Ensure your pump output does not exceed the filter’s maximum flow rate of 11.4 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 80 kPa, clean when gauge reads 130 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 and spas 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	4.6 m² (50 ft²)
Flow Rate	11.4 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 CC50 Advantage:

The Trimline CC50’s 30-micron filtration captures particles finer than a human hair, effectively removing dirt, debris, skin cells, sunscreen residue, and algae spores. Despite its compact size, the 4.6 m² pleated surface area delivers impressive filtration capacity for smaller pools and spas.

The cartridge design provides consistent whole-media filtration without the channelling issues sometimes found in sand filters. Combined with zero backwash water loss, the CC50 offers both effective filtration and water efficiency – particularly valuable for spa and hot tub owners who want to minimise water changes.

💬 Frequently Asked Questions

Q: What size pool will this filter handle?

A: The Waterco Trimline CC50 is suitable for pools and spas up to 68,400 litres. For optimal 6-hour turnover, it’s ideal for pools between 25,000 and 55,000 litres. The 11.4 m³/h flow rate makes it perfect for smaller residential pools, above-ground pools, and spa installations.

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. Spas may require more frequent cleaning due to higher bather loads relative to water volume.

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, oils, or lotions (common in spa use), 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. Spa cartridges may need more frequent replacement due to higher concentrations of body oils and lotions. Genuine Waterco replacement cartridges (part 1597273050) are available, along with quality aftermarket alternatives.

Q: What pump do I need?

A: Match the CC50 with a pump delivering between 8 and 11.4 m³/h. The pump flow rate should not exceed the filter’s maximum of 11.4 m³/h. Many smaller single-speed or variable speed pumps are ideal partners for the CC50.

Q: Does this filter require backwashing?

A: No. The Trimline CC50 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 spas, hot tubs, and locations with water restrictions.

Q: Is this suitable for a hot tub or spa?

A: Yes, the Trimline CC50 is excellent for spa and hot tub applications. The operating temperature range of 4°C to 50°C accommodates heated water, and the compact 605mm height fits neatly into spa equipment compartments. The flow rate is well-suited to typical spa circulation pumps.

Q: What warranty is included?

A: Waterco provides a comprehensive 10-year tank warranty (5 years full coverage plus 5 years pro-rata) and 1 year warranty on all other components. Commercial installations attract a 1-year tank warranty. Contact Parts4Tubs for full warranty terms and conditions.

Q: What is the micron rating?

A: The standard Waterco pleated polyester cartridge filters to approximately 30 microns, capturing particles finer than a human hair. This provides effective removal of dirt, debris, algae, and other contaminants for clear, healthy water.

Q: How does the CC50 compare to the larger CC75 and CC100?

A: The CC50 is the most compact model in the Trimline range, ideal for smaller pools up to 68,400 litres. The CC75 handles pools up to 100,800 litres, while the CC100 suits pools up to 136,800 litres. Choose based on your pool volume and desired turnover rate.
