5.8 Filter mats
Cleaning intervals
The cooling air is drawn in through two dust filters. Depending
on the installation site, clean the filter mats or, if necessary,
replace them after approx. every 100 hours of service. To
ensure a trouble-free service of the unit, exclusively use original
spare filter mats.
Take the opportunity to check the heat exchangers of the air-
conditioning unit as well to see if they are dirty. (Section 5.10).
Dirty heat exchangers considerably reduce the capacity of
the air-conditioning unit. Vacuum-clean the heat exchangers if
necessary.
