to be cleaned periodically with pressure air and the air suction filter units in the EC-F / EC-FD
universal unit have to be cleaned or replaced. They are located in a plug-in box underneath the
cooler unit. The filter elements are removed as follows:

Remove the crossbars holding the filter element by pulling with moderate force in the direction
of the filter element axis;
