RQ-H95 - Atlas H95 Replacement Quartz Sleeve and Luminor RQ-600

This is the replacement quartz sleeve for the Atlas H95 ultraviolet disinfection system, also sold under the Luminor RQ-600 name. It's a domed-end sleeve supplied complete with its O-ring seal, and WrekinWater stocks it as a straightforward drop-in replacement for a cloudy, scaled or scratched original.

Signs your quartz sleeve needs replacing

• The sleeve looks cloudy, scaled or scratched rather than clear.
• There's a brown or yellow tint to the quartz itself.
• Your UV monitor or alarm is triggering even though the lamp is lit.
• It's been in place for around 12 months or more, the standard replacement interval.

The quartz sleeve keeps the UV lamp completely dry while still letting UV-C light pass through into the water around it. As the quartz scales up or scratches with age, less UV light actually reaches the water, so disinfection becomes unreliable even though the lamp is still glowing and everything looks normal on the outside.

WrekinWater is a family run business that has supplied UV and water treatment parts to more than 50,000 customers over 15 years from Bettisfield, Shropshire, and holds an "Excellent" rating on Trustpilot. Ordering the correct sleeve for your specific Atlas or Luminor model first time avoids a wasted return.

How to replace it

1. Turn off the UV unit and isolate the water supply to the housing.
2. Drain the chamber and undo the retaining nut or union cap at the base.
3. Carefully withdraw the UV lamp, then slide out the old quartz sleeve.
4. Wipe the housing clean and fit the new O-ring before inserting the new sleeve.
5. Refit the lamp, reassemble the retaining nut or union, and restore water and power.
6. Run water to drain for a minute or two before using it for drinking.
