The 602810-102 UV sterilizer lamp and sleeve combo is a matched UV replacement set that includes a replacement UV lamp and a quartz sleeve for compatible UV water disinfection systems. Replacing the lamp and sleeve together helps restore UV performance when annual lamp service is due, when the sleeve is cloudy or scaled, or when you want to complete the most important UV maintenance items in one service visit.
Model number: 602810-102
What is the 602810-102 UV Sterilizer Lamp and Sleeve Combo Used For?
- Routine UV system maintenance when UV lamp replacement is due

Compatibility Checks
Before ordering, confirm:
- Your UV system model lists 602810-102 as the correct lamp and sleeve combo
- The part number on your existing lamp/sleeve documentation matches 602810-102
- The lamp connection style matches your system controller and connector
- Sleeve length and end fit match your UV chamber requirements
Do not substitute a different lamp or sleeve that looks similar. UV lamps and sleeves are model-specific.
What’s included

- (1) quartz sleeve
If your product listing specifies that O-rings or seals are included, keep that language exactly as shown on the product page. If not listed, do not assume they are included.
Installation Guidance: 602810-102 UV Sterilizer Lamp and Sleeve Combo
Install difficulty: moderate
Straightforward service, but correct handling and leak-free sleeve resealing are important.
- Turn off power to the UV system and allow the chamber to cool.
- Shut off the water supply if required for sleeve service on your system.
- Open the controller access area and disconnect the lamp connector.
- Remove the existing lamp carefully. Avoid touching the glass with your bare hands.
- Remove the existing quartz sleeve as directed for your UV chamber.
- Inspect sleeve seals and seating surfaces. Replace seals if your system uses serviceable O-rings that show signs of wear or leakage.
- Install the new quartz sleeve and confirm it is seated correctly.
- Insert the new UV lamp and reconnect the connector securely.
- Restore water and check for leaks at sleeve seals.
- Restore power and confirm the system returns to normal operation and clears any service indicators.
- Recheck for leaks after a short run time and again later the same day.
Replacement Triggers
Replace the lamp and sleeve combo when:
- It has been about one year since the last lamp change (common UV maintenance interval)
- The system displays a lamp-life or lamp-related alert
- The lamp still lights, but performance is reduced due to age
- The sleeve is cloudy, scaled, stained, etched, cracked, or cannot be cleaned effectively
- Maintenance history is unknown, and you want to reset UV performance to a known baseline
Maintenance Schedule
- Replace the UV lamp on a consistent schedule (commonly about once per year)
- Inspect the quartz sleeve during lamp service and replace if not cleanable or if etched/cloudy
- Inspect seals during service and replace if flattened, cracked, or leaking
- Maintain upstream sediment filtration to reduce turbidity and help keep the sleeve cleaner
FAQs on UV Sterilizer Lamp and Sleeve Combos
Q: How do I confirm 602810-102 is the correct lamp and sleeve combo for my system?
A: Match your UV system model number and confirm it lists 602810-102, or match the part number shown in your system documentation or previous order history.
Q: Why replace the lamp and sleeve together instead of just the lamp?
A: Lamp output declines over time, and a cloudy or scaled sleeve can block UV light. Replacing both helps restore UV exposure and reduces the need for repeat service.
Q: My UV lamp still turns on. Do I still need to replace it?
A: Often yes. A lamp can light while producing less UV output, which is why routine replacement is common.
Q: Do I need to shut off the water to replace this combo?
A: Lamp replacement typically requires powering off. Sleeve service may require shutting off water, depending on your system design and sleeve access.
Q: Will replacing the lamp and sleeve clear UV alarms?
A: It can if alarms are related to lamp life or reduced UV transmission from the sleeve. If alarms persist, check connections and consider troubleshooting the ballast or controller.
Q: Can I install this myself?
A: Many homeowners can with careful handling and correct resealing. If you are not comfortable servicing the sleeve and seals, a technician is a good option.
Q: Do I need new O-rings during sleeve replacement?
A: If seals show wear, flattening, cracks, or leak signs, replacement is recommended to prevent leaks.
