Safety switch for the UV lamp cover
The UV lamp cover is protected with a safety
switch. The safety switch has a reed switch and
comprises two components. The safely switch
ensures that the UV lamp only generates UV radia‐
tion in its fitted state. If the safety switch is
removed, then the UV lamp switches off. If the
safety switch is not fitted and thus remains closed,
e.g. after installation and maintenance work, then
the UV lamp cannot be started.
Maintenance of the UV system is limited to cleaning the UV sensor
window and replacing the UV lamps at the end of their maximum
permissible service life. In systems with wipers, replace the wiper
element and the O-ring of the clamping screw as well.
In systems that have a fan in the control cabinet, regularly replace
the filter mats of the fan and air outlet filter on the control cabinet
(normally once per year). Keep an operating log as a record; a
form is included in the Appendix.
