<p>The disinfectant device for the toilet pan leaves no residual traces, and operates by ultra violet rays on the inside surface of the pan on the top and on the lid. The ultra violet source is contained in the toilet lid(s). A second disinfectant lid folds down over the seat. When the lid is lowered, a switch lights up the ultra violet tubes or lamps. The ultra violet radiation does not reach the user, in normal use. The ultra violet device can also be used for toilets with only one lid.</p> |
