Control is the basis of maintenance. If you carry out the inspection carefully, arising prob-
lems can be avoided.
9.1 Inspection interval
When the surrounding air is polluted, the required coolant air quantity cannot be
achieved, because the dirt will clog up the ventilation grids.
Even before clusters of dirt inside the appliance can block the required heat dissipation.
Layers of dirt on the ventilation grids are a warning signal which you should keep an eye
on.
h check the devices (e.g. air filters) within the switching cabinet which ensure the re-
quired environmental conditions and be sure to keep the maintenance intervals given
by the manufacturers.
h weekly check the specified environmental conditions.
The specified environmental conditions you will find in chapter Z Appendix D - Technical
specifications – from page 97.
h monthly check the mixture ratio of the anticorrosive
(applies to window variant F only).
