What Is Included This combo kit contains one genuine VIQUA S410RL-HO high-output UV replacement lamp, one QSO-410 quartz sleeve, and two O-rings required for proper installation. Compatible Systems The QL-410 combo kit is compatible with the following VIQUA UV systems: VH410, VH410-V, VH410M, VH410M-V, VH410-F20, PUV-14, JSA-1000, and UV-Q-01 series. Recommended Replacement Schedule Replace your UV lamp every 12 months. UV lamps naturally weaken over time and lose disinfection effectiveness after one year of use, even if the light is still visibly on. Replace your quartz sleeve every 24 months or sooner if mineral build-up, cracks, or chips are visible, as a dirty or damaged sleeve blocks UV light from reaching your water. Why Genuine VIQUA Parts Matter VIQUA UV systems and lamps are tested and certified together as a complete unit. Using a genuine VIQUA lamp guarantees your system continues to deliver the certified UV dose your water requires. Aftermarket and counterfeit lamps may appear identical but often fail to provide adequate UV output, putting your household water safety at risk. Using non-VIQUA lamps also voids all UV system certifications and may compromise your manufacturer warranty. Specifications Lamp Model: S410RL-HO. Sleeve Model: QSO-410.
