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

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

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

What is the Purpose of a Sleeve in UV Filtration?

The clear tube that protects a UV lamp is called a "UV sleeve" and is generally made of quartz. The UV quartz sleeve is an essential part of any UV water filtration system. The protection sleeve 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.

How Often Should a UV 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 UV light effectiveness. Thorough cleaning and maintenance of the quartz sleeve is recommended every 12 months. You may want to clean the UV sleeve at the same time you're replacing the UV lamp each year. The quality of your household water may necessitate cleaning the sleeve more often. In fact, some customers pull out their quartz sleeve and clean it every few months. NOTE: Some UV lamps have a lifespan longer than 12 months, but generally UV lamps should be changed out every 12-24 months.

When Should a UV 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.

How to Clean a UV Lamp?

A UV lamp 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. Learn more about how to replace a UV lamp here.
