How to Clean a UV Sleeve

How often should a quartz sleeve be cleaned?

Regularly cleaning the UV quartz sleeve of your UV water purifier is important because contaminant buildup on the sleeve can hinder UV transmission and reduce overall system effectiveness. Thorough cleaning maintenance of the quartz sleeve is recommended every 12 months (when replacing the UV lamp), and the sleeve should be replaced every 24-36 months. Depending on the quality of your water, you may need to pull out the quartz sleeve and clean it every few months.

Instructions for Cleaning a UV Quartz Sleeve: 

  1. Close all faucets and turn off the water supply.

  2. Press the pressure button to release the pressure from the cartridges.

  3. Unplug the power. There may be an alarm that goes off as a warning.

  4. Check to make sure the UV system is not too warm. You may want to allow the system to cool down for 10 minutes.

  5. Carefully remove the protective cover or safety cap (at the top of the UV system) by squeezing the tabs, but make sure the lamp plug wires remain connected.

  6. Remove the lamp plug, but make sure the strain relief wires remain connected.

  7. We recommending putting on gloves before removing the lamp/sleeve as oils on the skin can damage the UV lamp or sleeve.

  8. Remove the lamp/sleeve assembly along with the sleeve bolt from the chamber.

  9. Unscrew the UV lamp by holding the sleeve bolt.

  10. Unscrew the sleeve bolt and remove o-rings from the quartz sleeve.

How do you clean a UV light?

A UV light should not be cleaned. Instead, it should be replaced at least every 12 months or 9,000 hours of service.

Many UV systems have a controller that indicates when it's time for a lamp replacement. The UV system indicator may be a visual cue like a green light, an audible alarm or an LED display countdown from 365 until the replacement due date.

How often should a UV quartz sleeve be replaced?

It is recommended that all quartz sleeves be replaced every 2-3 years. Completely replacing the sleeve every 24-36 months will ensure the UV system continues to operate properly. 36003034.jpg

What is a quartz sleeve?

The clear tube that protects a UV lamp is called a sleeve and is made of quartz. The UV quartz sleeve is an essential part of any UV water filtration system. This barrier can gradually become coated with mineral deposits and other contaminants, but its' job is to be a barrier between the UV lamp and the water flowing past.
