Initially and after a period of non-use, disinfection of the plumbing system downstream of the filter is re- commended, in some circumstances, before putting it into operation. Ultraviolet Irradiation The unit should incorporate a device for monitoring or sensing ultraviolet transmission througli the maximum depth of water in the chamber The monitoring or sensing device should be designed to trigger an alarm should the lamp or sensor fail or if insufficient ultraviolet light reaches the sensor Ultraviolet irradiation will work best when voltage or cycle variations do not exceed manufacturers' specifications. Since ultraviolet treatment does not provide residual bactericidal ac- tion, disinfection of the distribution system is recommended after any period of non-use. The device should be cleaned regu- larly Tlie output of an ultraviolet device decreases with age, so the lamp should be changed periodically as ,1 typicdl l\ irrudiiitiiin deviw m.
