Note This unit is protected by a micro switch which prevents the UVC light from illuminating when the cover is removed even if the power is on. This is a safety mechanism as UV light can be damaging to eyes and skin.In order to check the UVC lamp is operating remove the spray bar and hold a piece of plain paper up to the UVC outlet. A faint blue reflection should be seen. This operation may need to be carried out at dusk as the UVC lamp emits a faint a dim blue light under normal operation
