How much maintenance to the UV system is required?
A. Aside from a periodic cleaning of the quartz tube and scheduled lamp replacement (easily accomplished by the homeowner after 13,000 hours), no other maintenance of the Series 4 system is required. Consult the Series 4 Owner Manual for full specifics. Note that due to pond water containing larger amounts of organic materials, cleaning of the quartz tube more often may be required in some installations. Should green water appear in the pond, the fouling of the quartz tube and operation of the lamp should be checked.
