🔬 How It Works

The H.R.UV-C Single Classic employs advanced UV-C technology combined with a revolutionary super reflective chamber:

Water enters H.R.UV-C → Passes through E-PTFE reflective chamber → UV-C light destroys microorganisms →

1️⃣ E-PTFE SUPER REFLECTIVE CHAMBER

The unique E-PTFE (Expanded Polytetrafluoroethylene) reaction chamber provides the highest UV reflective index on the market. This extremely repellent material maintains up to 95% UV reflection, dramatically amplifying the exposure of microorganisms to sterilising UV-C radiation.

2️⃣ UV-C LAMP STERILISATION

The powerful 55W low pressure/high output UV-C lamp emits germicidal ultraviolet light at 254 nanometres. This wavelength penetrates microorganism cell walls and disrupts their DNA/RNA, preventing reproduction and effectively neutralising:

• Bacteria
• Viruses
• Algae
• Fungi
• Parasites (including Cryptosporidium and Giardia)

3️⃣ AMPLIFIED PATHOGEN DESTRUCTION

The combination of the UV lamp and the super reflective E-PTFE chamber means microorganisms receive multiple exposures to UV-C radiation as light reflects throughout the chamber. This dramatically increases sterilisation efficiency compared to standard UV systems.

→ Only sterilised water returns to your pool

Key Advantages of E-PTFE Technology:

• Highest UV reflective index available
• Extremely repellent surface maintains reflectivity
• Up to 95% UV reflection amplifies sterilisation
• No harmful gases or by-products produced
• Neutralises pathogens that traditional chemicals cannot

🔆 Lamp Life Indicator System

The H.R.UV-C Single Classic features an analogue lamp life indicator with colour-coded LED status:

LED Colour	Hours Remaining	Action Required
🟢 Green	9,000 – 500 hours	Normal operation
🟡 Amber	499 – 1 hours	Order replacement lamp
🔴 Red	0 hours	Replace lamp immediately

How the Indicator Works:

At initial power on, the LED indicator lights red for one second to confirm the 9,000-hour setting, then immediately changes to green to indicate the timer has started.

When the timer reaches less than 500 hours, the LED changes from green to amber — this is your signal to order a replacement lamp from your distributor.

When the timer reaches zero, the LED changes to red, signalling that the UV lamp should be changed immediately.

Resetting the Timer:

After changing the UV lamp, press and hold the reset button until the LED indicator goes off and then comes back on. When released, the LED will show red for one second followed by green, confirming the timer has restarted at 9,000 hours.

🛠️ Installation

Mounting Requirements:

Requirement	Specification
Position	Vertical or horizontal wall mounting
Clearance	Minimum 1 metre from one side for lamp access
Fixing	Wall mounting kit included
Environment	Dry, permanent, weather-proof area

Critical Installation Notes:

⚠️ Install AFTER pump, filter and heater

⚠️ Install BEFORE chemical dosing equipment

⚠️ Do not run this unit dry

⚠️ Do not cover this unit

⚠️ The unit must not be submerged in water

⚠️ Leave minimum 1 metre clearance for lamp/quartz sleeve replacement (lamp can be replaced from either end)

⚠️ Must be installed within a dry, permanent weather-proof area

⚠️ If water or moisture enters the enclosure, warranty will be void

⚠️ Carefully examine the unit after installation — do not power on if there is water on any parts not intended to be wet

💡 Tip: Flow direction is factory set for water entering on the left and exiting on the right. This can be reversed by rotating the flow switch 180 degrees (½ turn) if required.

💡 Winter Storage: If unused during winter months, drain the unit to prevent frost damage. Water must not be allowed to freeze inside the unit as this will cause severe damage.

Plumbing Notes:

• All factory unions are made from ABS plastic
• When gluing connections to ABS pipe, use ABS cement
• When using PVC pipe, use Transition cement
• No need to use mastic or PTFE tape — use the O-rings provided in the groove on the manifold assembly
• Apply glue evenly to all contact surfaces to reduce risk of leakage

🔧 Maintenance

Routine Tasks:

Task	Frequency
Check lamp life indicator	Monthly
Inspect connections for leaks	Monthly
Replace UV lamp	When indicator shows red (0 hours) / 9,000 hours
Clean quartz sleeve	During lamp replacement
Replace O-rings	Annually
Inspect lamp connectors	Annually

Analogue Lamp Life Indicator:

LED Status	Meaning	Action
🟢 Green	9,000–500 hours remaining	Normal operation
🟡 Amber	499–1 hours remaining	Order replacement lamp
🔴 Red	0 hours – lamp expired	Replace lamp immediately

Annual Maintenance Includes:

• Changing lamp if necessary
• Inspection and cleaning of quartz sleeve (replace if any cracks are discovered)
• Replacing all O-rings
• Replacing lamp connectors (white plastic insert inside the blue lamp shroud) if corroded, wet, damaged or overheated
• Inspecting plastic body and blue compression fittings for excessive wear

⚠️ Important: Before performing any maintenance, isolate from the main power supply, turn off the circulation pump, and drain the unit.

⚠️ Warning: UV light is damaging to eyes and skin. Never handle or look directly at an illuminated UV lamp.

Quartz Sleeve Cleaning:

Clean the sleeve and polish with a soft cloth or paper towel. In hard water areas, limescale can be removed by soaking the sleeve in a proprietary kettle descaling solution (follow manufacturer’s instructions).

💡 Note: Failure to remove limescale will limit the effectiveness of the UV lamp.

Replacement Parts Reference Codes:

❓ Frequently Asked Questions

Q: What is the E-PTFE reflective chamber?

A: E-PTFE (Expanded Polytetrafluoroethylene) is a super reflective material that provides the highest UV reflective index on the market. It maintains up to 95% UV reflection, dramatically amplifying microorganism exposure to sterilising UV-C radiation for supreme efficiency.

Q: How does UV-C sterilisation work?

A: UV-C light at 254 nanometres penetrates microorganism cell walls and disrupts their DNA/RNA, preventing reproduction and effectively neutralising bacteria, viruses, algae, fungi, and parasites including Cryptosporidium and Giardia.

Q: What size pool is this suitable for?

A: The HR-55-UK is designed for pools up to 55,000 litres (55m³) with a minimum filtration turnaround of three times per day. Ideal for medium to large residential pools and smaller commercial installations.

Q: How does this compare to the Mini Classic?

A: The Single Classic (55m³) offers nearly double the capacity of the Mini Classic (30m³) with a more powerful 55W lamp versus 30W. It handles higher flow rates (16m³/h vs 12m³/h) for larger pool systems.

Q: Will this fit my system?

A: The H.R.UV-C connects via 2″/63mm stepped ABS unions, with reducers included for 1½”/50mm pipe. Ensure your flow rate is at least 1.5m³/h and does not exceed 16m³/h.

Q: How long does the UV lamp last?

A: The UV lamp has a usable life of 9,000 hours under normal conditions, which is approximately 2 years. The analogue lamp life indicator monitors remaining hours and alerts you when replacement is needed.

Q: How do I reset the lamp life timer?

A: After replacing the lamp, press and hold the reset button until the LED indicator goes off and then comes back on. When released, the LED will show red for one second followed by green, confirming the timer has restarted at 9,000 hours.

Q: Does this eliminate the need for chemicals?

A: UV-C sterilisation does not provide residual sanitisation, so it must be used in conjunction with chemical sanitisers. However, it significantly reduces chemical dependency by destroying pathogens that chemicals cannot, and helps reduce chlorine odours.

Q: Is this compatible with salt water?

A: Yes. The H.R.UV-C is 100% compatible with chlorinated salt water and sea water pools.

Q: What’s the warranty?

A: 2 years within Europe, 1 year outside Europe. The warranty does not include serviceable parts such as lamps, quartz sleeves, and O-rings.

Q: Is there a Pro model available?

A: Yes. The HRP-55-UK includes a digital lamp life countdown and intelligent peristaltic dosing pump for automated chemical dosing.

Q: Are there smaller or larger models available?

A: Yes. The Mini Classic (HR-30-UK) treats pools up to 30m³, and the Double Classic (HR-110-UK) treats pools up to 110m³.
